There are over 3000 documented species of spiders in North America. The vast majority of these are not dangerous. Most of them have fangs that are not strong enough or are too small to pierce human skin. If they manage to bite, they leave behind red wounds that are itchy and heal in about a week.
Spiders with fangs strong enough to puncture human skin and inject toxic venom can cause major health problems.
How spider bites look like?
If you suspect you have been bitten by a spider these are the signs to look out for:
- Skin damage
- Muscle pains
- Red or purple colored blister
- Breathing difficulties
- A red welt
- High blood pressure
- Swollen lymph glands
Because they more often than not affect skin tissues, spider bites take quite a while to heal.
Here are a few types of spider bites and their symptoms.
They are found all over the United States. They have two large eyes at the center of their faces and six eyes in a row below these. They are about 4 inches in length and very hairy. They stalk their prey on the ground.
When you get bitten by wolf spider, you will experience pain, swelling and redness at the bite site. Your lymph nodes may swell also because of the bite. The bite can cause tissue damage though this rare. Healing takes as long as 10 days.
Brazilian wandering spider
Mostly found in South and Central America this spider measures in at 5 inches long. It’s movements are very quick and aggressive. It’s venom is one of most toxic in the world.
This spider’s bite is extremely painful. It results in drooling and heavy sweating. Around the bite, the skin will get hot, swell, and turn red. The Brazilian wandering spider bite can be fatal.
If bitten get to an emergency room immediately.
This spider is ubiquitous in North American houses. Its body is hairy and stout and about half an inch long. It moves in erratic jerky jumps. If threatened it will bite.
This spider’s bite can be as painful as a wasp sting.
Symptoms present as pain, headaches, swelling, redness and itching.
The Black widow has a black shiny body with long spindly legs. It’s bulbous abdomen has a red hourglass shaped mark. It prefers quiet places like woodpiles, storage boxes in attics and piles of dead leaves to name a few.
A bite from a black widow feels like a pinprick. The fangs will leave two puncture marks on the skin.
Black widow bite symptoms include:
- Pain and burning at bite site
- High blood pressure
- Nausea and vomiting
- Muscle cramping
- Increased salivation
Get to a doctor as soon as possible if you experience any of these signs and more so if it’s an elderly person or a child.
This spider thrives in desert climates. It is about 3 inches in length. It has large jaws and a bite can inflict a significant cut in human skin which may experience mild bleeding and swelling.
For spider bites it’s better to err on the side of caution. See a doctor.
The funnel spider happens to be one of the deadliest arachnids in the world. The critter, which is native to Australia, is considered to rank the deadliest creature because it can kill within 15 minutes with just a single bite. In fact, there are reports indicating that about 15 deaths were caused by bites from this spider between 1927 and 1981.
Although male funnel spiders are more dangerous than their female counterparts, they live for about 8 years less.
In Australia, the funnel spiders can be found within a range of 100 miles in Sydney, and most are found in crevices between rocks, under houses, or in trees and holes. Humans are more vulnerable to their bites more than any other domesticated animals, such as dogs and cats.
The Common Species
These spiders are generally shinny and black and have a distinctive appearance. Although there are about 40 species, the common one is the Sydney Funnel-web (Atrax robustus).Until the discovery of the anti-venom in 1980, there were more than 13 human deaths that were caused by the males of this species.
Male Sydney funnel-web spiders contain a component in their venom which is missing in females. The toxin is referred to as Robustoxin, which is the active chemical that makes these spiders rank among the deadliest in the planet. Interestingly this toxin only affects primates (humans, apes, and monkeys)but is relatively less hazardous to other animal species.
Funnel Spider Hideouts and Distribution
Unfortunately, these spiders’ natural habitat is found in densely populated areas such as Sydney, Australia. The discovery of the anti-venom has greatly diminished the danger posed by the venom from these spiders. In about 40 years, no death has been caused by the Sydney funnel-web spiders, but the fear of these critters is still a reality in Australia.
Funnel-web spiders are commonly found within silken retreats underground, while some can inhabit places like hollows and crevices in trees. Most of the species prefer moist habitats like shaded gullies in the middle of forests. The species is widely distributed in Australia from South Adelaide (Adelaide Hills) to parts of Victoria, Tasmania, and along the east coast of Queensland.
Species that live underground naturally occur between rocks and logs. They have tube-like openings of silk, and mostly bare distinct silk strands also known as trip lines.These lines help to alert the spiders of the presence of prey whenever they are hunting. Funnel web spiders normally take small vertebrates like frogs and lizards. They also consume insects and other spiders.
These spiders simply ambush the prey and overpower them. They bite and drag prey into their retreat where they feed on them. In order to hunt, these spiders are highly sensitive to vibrations. Encounters with humans are often accidental and happen when people are digging. Human encounters can also occur when males are roaming around to look for companions during the mating season.
The funnel-web spiders are readily preyed upon by centipedes.
Funnel SpiderBite Symptoms
Symptoms of funnel-web spider bite starts early and may include:
- Tingling around the mouth
- Profuse salivating
- Muscle spasms
- Watery eyes
- Twitching of the tongue
- Elevated heartbeat
- Respiratory distress (which) can be fatal
The Australian funnel spider is native and exclusive to Australia. it is often confused with the funnel weaver spiders in the family Agelenidae, found in the states. The funnel Weaver from the states in not poisonous and neither are the two spider species related in any way.
The funnel-web spiders are commonly found in Australia and the males happen to be among the deadliest species in the world. Their bites can cause a fatality in less than 15 minutes. The anti-venom to their toxic chemical was invented in 1980, and no death has been reported ever since.
Commonly found throughout the United States, The Brown recluse spider and wolf spider are often confused for each other. They look alike and even inhabit similar surroundings. There are, however, discernable differences.
The Brown recluse spider gets its name from its preference to live in areas of a home that are secluded. They live for about 18 to 24 months. The best way to identify the brown recluse is a ‘violin shaped’ marking at the back of its head. This has earned brown recluses the names fiddleback or violin spiders.
Brown recluses are about half as large as the wolf spider. People cannot tell them apart because they are both brown. The brown recluse, however, always has a uniformly covered abdomen, tan to dark brown. Its legs are slender, often covered in fine hair. Wolf spiders are brown, gray or tan, with dark markings.
Brown recluses molt and shed their exoskeleton five times before reaching adulthood. A mature brown recluse is about as big as a fifty cent piece.
Brown recluses usually rest on their webs during the day but come out at night to hunt for their food. They will catch live prey or feed on dead insects, even other brown recluse spiders.
While most spiders have eight eyes, the brown recluse has 6, arranged in a semi-circle.
The Wolf spider is large, hairy and not as venomous as its appearance. An adult wolf spider is about 1.5 inches. It gets its name from its stealth tactics when hunting for prey. Wolf spiders will also prey on brown recluse spiders.
Wolf spiders have prominent eyes that shine in light, almost like a cat’s. Don’t go stroking one on the head. Wolf spiders also have excellent night vision and are experts at camouflage.
Wolf spiders live almost everywhere in the world, especially in grasslands and meadows, but also in mountains, deserts, rainforests and wetlands. Their favorite hiding places are abandoned buildings, closets, sheds, attics, garages, yards and basements.
Brown recluse venom vs Wolf venom
Both brown recluses and wolf spiders are venomous, but not lethal. However, there is a very good reason why these often confused spiders should be told apart. A wolf spider’s bite will not do any serious damage. Redness or swelling may occur, but would disappear after a few days.
A brown recluse’s bite is usually painless, because they have very small fangs. Redness or swelling usually appears 3 to 8 hours after being bitten. An itchy or burning sensation will then develop over the course of several hours.
The venom injected by the brown recluse is usually localized to the bitten area. If the venom is minimal, the discomfort goes away after about 4 days. If not, the venom spreads, causing necrosis.
The Brown recluse and wolf spider are rarely aggressive and would only bite when feeling trapped.
If bitten, you should try and find the spider before it scurries off. Elevate the area and apply ice. The ice helps to slow down the spread of venom in the body. Immediately seek medical help.
Camel spiders are a global sensation due to online viral feeds. There are many urban legends and exaggerations about their size, speed, behavior, appetite and lethality. But the real deal is just as interesting.
The camel spider is not an actual spider, but a ‘solifugae’, meaning ‘those that flee from the sun’. Also called sun spiders and wind scorpions, camel spiders were first found in the Middle East and later in the sandy areas of the South West United States and Mexico.
Nearly 900 species have been discovered. They have been called camel spiders because they were originally found in regions where camels are native, not because the spiders feed on the stomachs of camels as popularly perceived.
Bite victims can rest easy. The camel spider is not venomous in nature. In fact, they hardly cross paths with humans due to their habit preference. Camel spiders are not dangerous to humans and will only bite in self defense. The danger of being bitten by a camel spider is minimal.
They, however, have a powerful set of jaws called chelicerae, about one third of their body weight. A large camel spider can inflict a painful nip, but nothing that needs medical attention.
Appearance and behavior
Different myths and stories about camel spiders began to spread during the Gulf war and resurfaced at the beginning of the Iraq war in 2003.
Camel spiders are usually about 6 inches in length when fully grown. They can run at an average of 10 mph. That’s about one third the speed of a professional marathon athlete. They are beige to brown in color.
The camel spider’s body is very hairy, down to its legs. Females are usually larger than males, with longer legs.
Before breeding, females will overfeed, as they will not hunt when reproducing. Males breed directly or deposit a sperm packet and pass it to the female with their chelicerae. A female camel spider can lay anywhere from 50 to 200 eggs. She will guard the eggs until they hatch.
Camel spiders are nocturnal, seeking shelter during the hot hours of the day and hunting at night. They will seek any form of shade when the opportunity arises, including human shadows. This gives the false impression of camel spiders following and even attacking humans.
Very little is known of camel spiders. This is because it’s very difficult to keep them alive in controlled conditions. Although they are not dangerous, camel spiders are subject to vilification and death as humans fear them.
Depending on the species, some camel spiders are carnivorous and some are omnivorous. The vast majority of species prey on termites, beetles, other insects and anthropods. Large species are opportunistic feeders and will feed on virtually anything captured.
Camel spiders will use their powerful jaws to seize their victims and turn them to pulp in a chopping and sewing motion. They are not venomous but will utilize digestive fluids to liquefy their victim’s flesh. This makes it easy to suck the remains into their stomachs.
A spider bite gives everyone the shivers. Read on what to do in case of one
Most spiders aren’t dangerous. Many spider fangs are not strong enough to bite through human skin.
The small percentage of spiders that can puncture human skin and deliver venom can cause major health problems.
Signs of a spider bite
You might get bitten by a spider and not be aware of it until much later when you notice the bite. There are signs to look out for to identify a spider bite including the following:
- Pimples parallel to each other, a purple or red color blister
- Skin damage
- Red welts
- Muscle pain
- Pain on the bite site
- Headaches, fever, nausea, chills, breathing difficulty, sweating and anxiety.
Spider bites may affect the skin tissues and therefore take long to heal. Keeping the site of the bite clean is vital to avoid infection.
Bites from non venomous spiders can be treated at home by :
Elevating the bite site will help reduce the swelling, apply an ice pack at intervals of ten minutes. Also clean the bite site with water and antibiotic soap to wash out any bacteria. Applying topical antibiotic to the bite area and taking an over the counter antihistamine under the guidance of a pharmacist will help. If the symptoms are not fading away seek see medical attention.
Types of spiders, effects of their bites and treatment to take
- Black widow
This spider is black with a red hourglass mark on its abdomen. It’s got long spindly legs and bulbous abdomen. It prefers hidden places such as storage boxes, Wood piles, under logs and leaf debris. The black widow inhabits the western and southern areas of North American. The black widow bite feels like pinprick and its fangs leave two puncture marks on your skin.
When bitten by a black widow you will experience headache, muscle cramping, sweating, nausea, vomiting, and increased saliva emission. Other symptoms may include pain and burning at the bite site, restlessness, numbness and high blood pressure.
Medical intervention is necessary. You need to get to an emergency room quickly.
Tarantulas are big and hairy. The can have a leg span of 6 inches they have big visible fangs. They are quite timid and will only bite when absolutely cornered. Though they look menacing their bite is not considered fatal to humans. The bite feels like a bee sting. The bite site will become red and feel warm. Other signs are: itching, rash, breathing difficulty, low blood pressure, and swelling.
You will need to see a doctor if you exhibit these symptoms.
- Brown recluse spider
The brown recluse spider gets its name from its color and habit of hiding away in secluded dark places. It’s got a unique violin shaped mark on is back and long legs. It inhabits Kansas, Missouri, Louisiana, Oklahoma, Tennessee and Arkansas.
The initial bite is not painful. It starts to turn red itchy and hurts after eight hours. A red ring similar to a bullseye forms around the bite. If not treated the bite will worsen killing surrounding tissue. It can cause, seizures, jaundice and kidney failure.
There is no anti venom for the brown recluse spider venom. To minimize chances of infection wash the bite site with water and antibiotic soap. See a doctor who will most likely prescribe antibiotics.
If you have noticed any large spiders lurking in your home or yard, it may be wise to call pest controller or exterminate them and reduce chances of spider bites.
They may be dark colored when they first hatch but before long baby tarantulas molt and acquire their hair and colorful designs like the adult tarantula. However, they don’t have venom whey when they first hatch
Like other spiders tarantulas carry an egg sac contain many spiderlings on average from 500 to 1000. Once the eggs hatch their parental responsibility ends there. Hundreds of spiderlings crawl out when the eggs hatch and they are left to fend for themselves.
As pets, tarantulas live anywhere. In their natural setting they like drier and warmer climates. In North America they inhabit the desert regions of Arizona, Texas and carlifonia. A majority of tarantulas species live in burrows abandoned by other spiders or burrows the holes themselves working with their fore legs and fangs. Some tarantula species weave webs in trees. These webs are funnel shaped.
What tarantulas eat
Like most spider species, tarantulas feed on insects like beetles, grasshoppers, caterpillars and cicadas. But the big tarantulas eat bigger prey such as birds, frogs, snakes, bats and rodents.
Most tarantulas have to hunt since they don’t have webs. They feel vibrations through their feet and body hairs. When they detect prey they jump on it and hold it using their front legs. They bite the prey and inject venom and digestive enzymes liquefying it for ingestion. Though some tarantulas can kill their prey with a bite, they cannot eat solid food.
All species of tarantula are venomous and use the venom to primarily inject and paralyze prey. Tarantulas are not interested in biting people, they will first try to get away from a threat, if that fails they bare their fangs and rear up in a threatening position. This is usually enough of a deterrent. Even then when they bite they will often bite without injecting any venom. The bite feels like a bee sting. In case you get bitten, err on the side of caution and seek medical attention.
Tarantulas are nocturnal and territorial but when the mating urge is on it overpowers every other sense and that’s when males will move during daylight regardless of the danger they are exposing themselves to. Female tarantulas hang around in their burrows waiting for a male to show up. Male tarantulas wander around looking for a mate. They deposit sperm on a web ball and carry it in on themselves as they move, searching for a female. When they locate a burrow with a female occupant they will tap on webbing lining the burrow to announce their presence. The male will engage in a mating ritual and if the female tarantula is receptive he will deposit the sperm and escape to avoid getting eaten. Males will die shortly after reproduction even if they avoid getting snacked on by the female.
After fertilization the female lays a silk cocoon with an egg sac holding at least 500 eggs. This happens inside the burrow. She will stay with the eggs guarding them until hatching time.
When the weather turns cold tarantulas will seek warm places such as a burrow or even inside homes. If you see them inside your home it is best to call a pest control professional.
Most black spiders with white spots are a type of jumping spiders. It’s not surprising that a lot of people react with fear and aversion to seeing a spider. Although hard to believe, most don’t pose any danger to humans. However, some spiders like a juvenile black widow which has white spots are very dangerous. There are over 3000 species of spiders in the United States and many are black with white spots. m
Most of them are harmless to humans. It’s useful to know how to tell them apart.
White-backed garden spider
The white-backed garden spider has white spots on its black back. These spots range from white to yellow to cream. The abdomen is oval shaped and there are strips of black and white on the legs. This spider is a beneficial because it eats other insects in your garden. That means it is a natural pest controller in your garden.
Wolf spiders have white spots on the back. They have eight eyes placed in a very unique order, two very small eyes at the very top, two big eyes below those and right at the bottom in a row are four small eyes. Most species patterns of color are not pure black and white but shades of gray. They have a hairy body measuring about an inch excluding the legs. The Wolf spider does bite people and though their venom is not fatal you will need a doctor to take care of that bite. The wolf spider digs a burrow and hides in it and waits for prey to pass by.
The bold jumping spider is black with white markings on its abdomen this includes an upside down smiley face looking pattern. The bold jumping spider moves in quick jerky movements and quick jumps. Females are bigger than males. Males have tufts of hair that appear like eyebrows. These creatures I sound mostly in open fields and have white or cream spots on their backs. While most spiders span a web to trap their prey, the jumping spider does not. Instead these spiders use their jumping prowess to take down their prey by catching them unawares. Bold jumping spiders can take leaps 50 times their body length. These spiders make a tent like web to protect themselves from harsh weather, store eggs and shelter when molting.
Male jumping spiders will attempt to copulate with any female they come into contact with. The indiscriminate mating habits of the males can sometimes turn fatal resulting in being eaten by the females which are more aggressive and bigger. There are even instances where male jumping spiders attempt to mate with spiders of different species often with deadly results. The male jumping spider, uses a specialized appendage to inject its semen directly into the female’s ova as females don’t have an opening for insemination. Jumping spiders live for about a year.
Purse web spider
The purse web spider is black and has white spots right behind its big fangs. Owing to their size and shape they can be mistaken for the black widow but they don’t have the widow’s red hourglass pattern.
While most of these spiders are harmless to humans they can be a nuisance and downright scary when they get into our homes. Call your local pest controller to determine what type of spiders you have and the best course of action to get rid of them.
The camel spiders are found in Africa, North America, South America and Europe. There are over 1100 species. They have four pairs of legs and what seems to be a fifth pair right at the beginning of the jaws. These are called pedipalps and are actually sensory organs, they help channel prey to the jaws. The body is divided distinctly in two sections like ticks, spiders, scorpions, mites, but these critters are not true spiders, they are in the animal order solifugae. They live in dry climates. They have a leg span of approximately 6 to 7 inches and body length up to 15 centimeters.
They are quite aggressive but have no venom. When they feel threatened they rear back and rub the jaws together producing a rasping, hissing noise. This is known as stridulation.
Camel spiders are mostly nocturnal and top predators. During the day they like to hide under rocks, logs and in underground burrows to keep away from the desert sun. They mostly live in dry climates. They prey on anything from termites, beetles, wasps, silverfish, scorpions to spiders and other solifugids. They will even cannibalize each other. Ants are the one thing it seems they don’t have a taste for. The camel spider will just kill the ants and not eat them.
How they hunt
Many arachnids modus operandi is to just sit and wait for prey to blunder into their traps and webs. Camel spiders are different. They are fast and quite indefatigable. They will run and keep running and when they meet a potential meal they will use those humongous jaws to cut them up, smear enzymes into the injuries and suck out the liquefied insides. They have to eat a lot to keep up their high rate of metabolism.
When a camel spider encounters something that moves it will rear up and begin feeling out the object with its pedipalps which have a friction adhesive quality. This enables the camel spider to climb even a smooth glass surface and latch on to their prey. It is curtains for the prey when that happens.
When mating, the male will caress the female with his pedipalps. The female falls into a trance like state. Next the male pushes his mandibles all the way into the genital opening of the female and moves them violently back and forth just like when he is feeding and then he pulls out. At this juncture the male of some species lay a packet of sperm on the ground. Using his jaws he will insert the sperm packet into the female’s genitals. In other species the male will briefly push his genital opening on to the orifice of the female genitals.
If there is any deviation in whatever manner from this sequence the female awakens from her hypnotic state looking to raise hell. She will twist and thrash around until she is free from the male. Then she will go after the male bite, kill and eat him.
In some individuals, spider bites can cause an allergic reaction that should be treated immediately, especially if it is greater than a mild reaction. To avoid getting bitten at home, use a natural spider repellent or when heading outdoors.
The use of natural insect repellent is proving to be a real and serious option to the much more conventional chemical-based remedies such as DEET.
This sort of organic repellent is sort of debatable, as is their treatment by some government authorities around the world. In European countries, for instance, these items are prohibited from sale as a bug repellent, even though there’s obvious proof that they can perform like one.
There aren’t any such limitations for the sale of chemical-based solutions, indicating that the Western European federal government looks at these to be completely risk-free and that the statements of all-natural insect repellent suppliers are bogus.
This may not be accurate, as there exists sufficient proof to suggest hazardous effects of chemical-based remedies, as well as evidence that all-natural solutions act as bug repellents. Research the facts and evidence prior to making your ultimate buying decision.
When examining the potentially dangerous results of chemical-based insect repellent, remember that the cases of significant issues with their use are very small. DEET, for instance, is used by huge numbers of people throughout the entire summer season.
Seizures, along with other direct unfavorable outcomes, are so uncommon that the chemical can be viewed as less dangerous than numerous foods that people are allergic to.
The actual issues with DEET as well as other chemical substances result from extended direct exposure. These issues are much more intangible than the usual immediate causation of illness.
Tests that have been performed on employees at National Recreation area facilities spanning a long period of time show that there’s a damaging impact of prolonged use.
Employees who are subjected to DEET every single day have reduced response times, much less psychological clearness, and elevated disruption of sleeping patterns.
The potential health risks of chemical-based bug repellent can’t be overlooked. It is crucial now that we start to analyze organic bug repellent solutions from an objective perspective, rather than accepting that anything which isn’t chemical substance based is not going to work.
Organic items like citronella oil have already been used as an insect repellent for many years, however, government authorities have recently chosen to prohibit their sale for this purpose. This really is with no proof to claim that they don’t possess the stated attributes.
In reality, evidence firmly shows that these ingredients can and do get rid of bugs. They’re much less harmful to work with, even though some individuals do encounter skin irritability with many organic products.
It really is an instance of attempting several to determine what you happen to be compatible with, and constantly keeping in mind the necessity to apply natural remedies more regularly.
It is sad to know that people are helpless in exterminating tiny bugs, including spiders. This is possible especially for households that are dirty and unsanitary. However, there are some ways that you can do on how to kill spiders and other bothersome insects.
They have become a problem for too long so it is time to exterminate them. Unwanted insects can bring damage to your house and bring diseases. Therefore, you should know how to start preventing them from thriving.
Even though they can be hard to eradicate, there are simple things that you can do to control them. Today, we will give you a few tips on how you can manage the pests at home.
First, consider how clean and tidy is your home. You know that pests will always thrive in dirty places. They make these places their home and food source.
Of course, if your house is full of dirt, they could easily consider it as their home too. You need to clean your house so you can keep the food morsels and trash away from the property.
These are the basic resource of pests that’s why they would like to come back to their home within your house. One of the things that you can do is to keep the trash away from the house.
Also, it is best if you could do general cleaning at least once a month. This will help you identify the potential places in your home where pests could thrive. You could also keep the corners and crevices of the house cleaner.
Next, identifying the types of pests that linger in your house helps a lot. There are so many of them and it requires knowing how they thrive. For example, a rat can live in small holes inside the walls of the house. This is their favorite spot to hide and eat.
Other pesky insects such as roaches and rodents thrive in garbage bins. They like a moist and dirty area that’s why they are disease carriers. They are also drawn to stay in your home’s cracks, crevices, and corners of the walls.
Once these annoying pests are have settled in the house, they have the leverage to attack anyone at any time. A good example is a mosquito.
They are flying inside the house and bite people where they can suck out the blood. Another example is the fly. They would normally hover around when foods are served on the table.
One last solution for you is to call a pest control expert. There are hundreds of these companies that could help you today. You can find some brands on the internet.
Of course, there are some factors that you need to consider first. The initial factor is their experience. You should be able to find their history when it comes to customer service. You can do the same research online as well.
