What Are Spiders?

Spiders, as we all have been taught since childhood, have eight legs. They actually have four pairs of legs. The way that spiders feed, or eat, is by turning their victim into liquid, and the pieces that don’t turn into liquid are filtered out and caught on their beard. Something else that many do not know about spiders is the fact that most spiders also have eight eyes, even though they don’t see very well. Spiders use touch to navigate with the aid of special hairs located on their feet.

Spiders breathe air, and their lungs are located under their body. Their body is in two parts, consisting of the acephalothorax and a stomach, or abdomen. Spiders are arthropods from the order of Araneae, and can be divided into two groups as modern spiders which made their beginning appearance during the Triassic Period. The two groups or sub-orders are as follows:

Mygalomorphae

Araneomorphae

The oldest surviving sub-order of spiders is the Mesothelae, which are very much like the true spiders. Spiders are known for the web that they produce, but not all spiders produce a web. They make this of proteinaceous spider silk which extrudes from their spinnerets. The common reason known why spiders would do this is to catch their food or prey. When a spider web is no longer in use, it is referred to as a cob-web, but there are exceptions to this also in the world of the spider.

Where Do Spiders Live?

Spiders live most everywhere in the whole wide world, except in the Polar Regions. They can live in almost any habitat imaginable. Spiders also do not live in the ocean, even though they are finding their ways to the edge of it and living amongst the rocks and coral of the intertidal. This area can be under water at times, usually briefly, during high tide, but somehow they survive.

The common House Spider often lives in your home or business, as the name implies. They can live in any structure including schools. House Spiders might spend their entire life inside your home or other structures. They like to live in places where people are not likely to see them.

Every once in a while you will see a House Spider scurrying across the floor or dangling from a thread as they make their spider web. Not all spiders make a web, though. A lot of younger children might think the spider’s web is their home, but they mainly make these to catch food. In this way they are of service when they eat insects which might be a pest to us.

It’s a little scary being too trusting of spiders, especially if you have children because some of them are highly poisonous, such as the female Black Widow. She does not create the beautiful spider web as we know it; she makes a kind of jumbled web which catches larger prey, such as Beetles. Spiders live everywhere, including your home.

What Kinds of Spiders Live in My Area?

The chief kinds of spiders that commonly live in Arizona are as following. It would not be surprising if these are living in your house, business, yard, or around the landscaping in the Arizona area. Spiders seem to love Phoenix, especially. In order to eliminate and develop a plan for keeping them from invading, you will need to work closely with an exterminator and pest control company.

House Spider

Tarantula

Giant Crab Spider

Black and Yellow Garden Spider

Jumping Spider

Wolf Spider

Brown Recluse

Black Widow

Some spiders are more harmful than others. The Black Widow is the most poisonous spider in the whole United States, and yes, it likes the Arizona area. The Brown Recluse is also dangerous. The Tarantula and the Wolf Spider are intimidating, but not a real big threat except in looks. Their bite can be painful. A lot of people like keeping the Tarantula as a pet. You will often see them playing a part in some big Hollywood movie.

Most spiders have a short lifespan, but the Tarantula can live as long as 25 years in ideal conditions. All spiders can bite, even though it is said that the male Black Widow doesn’t bite. It is best to be wary. Even the common House Spider can bite when surprised, but it is usually not serious. Be aware of the spiders that live in your area and take necessary precautions.

What Damage Can Spiders Inflict On You And Your Home?

Spiders cannot inflict as much damage on your home as they do you personally. Spiders are found in almost every home. Almost all spiders bite, and it can be painful, but not all spiders are poisonous enough to inflict harm in that way on a human being.

The most poisonous spider of all in the United States is easily identifiable because of its coloring and marking. It is called the Black Widow. The picture book perfect Black Widow is the female. She is the one that is shiny black with a bright orange, almost red hourglass shape. The bright color against black is really noticeable. She is about one and a half inches long, including her leg span. Usually when people get bit by a Black Widow female she does not inject enough poison to cause severe problems. The male Black Widow is smaller, and they are a grayish/black color with bright orange, reddish spots which are just spots, and not hour glassed shaped. It is said that the male Black Widow does not bite, but maybe that is said because it is not as poisonous as the female.

Other spiders may be in your home, including the Brown Recluse which is also poisonous, but usually does not cause great harm. In rare cases it can cause tissue damage where the bite was inflicted. You should be concerned about the spiders in your home inflicting damage on the humans present, and remedy a spider problem by getting hold of a pest control company as soon as possible.

What Do I Do If I Was Bitten By Spiders?

If you are bitten by spiders or a spider, the best thing to do is wash it well with soap and water. Try to identify the spider if you can, or at least describe its appearance. After you have washed the area good, you can use a cool compress for pain and to alleviate any swelling. You can make a homemade cool compress by using a dampened cold washcloth folded on some ice.

If you have reason to believe that it is a poisonous bite, such as from a female Black Widow or a Brown Recluse, raise the area if it is on an arm or leg. If in doubt, or you know the spider was poisonous, seek medical attention, because it is better to be safe than sorry. This applies even if you feel fine, but know that you got bitten by a Black Widow or Brown Recluse. Many times people will not even know they were bitten by a Brown Recluse because their reaction is so mild. It kind of all depends upon the person and the situation. The Black Widow doesn’t usually release, or inject a full amount of her poison, so the reaction to her might not be as bad as expected. But she can release a lot of poison, and in that case the bite is very serious. You just never know, and it is always best to be prepared if you get bitten by spiders or a spider.

What Can You Do If You Already Have Spiders?

Almost everyone already has spiders in their home, garage, and yard area. If you are beginning to notice an excess of spiders, see if you can identify them. Whether you can identify them or not, it is best to call your pest control company and let them know that you are having a problem with spiders. These are the spiders you might see in Arizona, in and around your house. Almost all spiders can inflict a bite.

Black Widow – Bite is very poisonous. It is considered the most poisonous spider in the United States.

Brown Recluse – Poisonous bite, but not fatal. Can cause serious skin damage to area around bite in rare cases.

It is best to stay away from spiders no matter what kind they are. Most spiders have to be provoked, or surprised to bite you or a loved one. If you already have spiders it is best to seek the advice of a pest control expert, and he/she will help you decide the best plan of action.

How Do You Prevent Spiders From Invading Your Environment?

The best way to prevent spiders from invading your environment is to seek the advice and services of a professional pest control company. There are certain conditions that seem to be an automatic invite for spiders, and clutter in one of them. Spiders love it when a home, business, or other area is cluttered. It makes so many places a great hideout.

Clutter can be in your office, at school in your locker, in your home, storage areas, and your yard. Your yard is a definite starting place for spiders to gain access to your home. Try to keep piles of leaves and other clutter away from your entryways. Often times a spider can gain access to your home in a shopping bag, carton, or box of some other means.

As you are coming and going from your dusty and cobweb laden storage unit, you can carry spiders home with you and into your house without even knowing it. Take time and shake out the stored Christmas decorations you carried in from the shed. A lot of spiders that have a tendency to enter your home lay 100’s of eggs all at the same time. Spiders lay eggs in sacks, and there may be as many as 200 hundred eggs in each sack. Many of the common house spiders lay 9, or so, of these sacs all in one sitting. Black Widows are no exception. Keep it in your mind how many eggs spiders lay as you are seeking to prevent spiders from invading your environment.

Are Spiders Dangerous For My Pets?

Spiders can be dangerous for you, and also for your pets. Many spiders are not a real harm, but a few are. These could make their way to your curious pet, or their bedding. Make sure you always keep your pet’s bedding clean and aired out. Fluff out your pet’s bed, and shake it out doors. Inspect the actual container, or pet abode, if they have one for spiders and other insects which attract spiders. Two spiders that can be harmful to your pet if they get bit by them are the following.

Brown Recluse – The Brown Recluse can inflict a bite which causes soft tissue damage, in rare instances. If your pet has been bitten by a Brown Recluse and displays a reaction on their skin that does not seem to be healing, you will need to take them to your veterinarian for treatment.

Black Widow – The Black Widow is the most dangerous spider in the entire United States. They can bite your pet, the same as they can bite you. Usually a pet gets bitten when they surprise a spider. Spiders do not go out of their way to bite humans or pets.

Pets do have an extra layer of fur which can sometimes make them harder to get bit by a spider. Pets also have areas of skin that is exposed and tender. Around the nose area is a common place for pets to get bit. Yes, spiders can definitely be a danger for your pets.

When Are Spiders Most Active?

Most spiders are nocturnal. This means they come out at night. Many of the insects they feed upon are also nocturnal. In the daytime they have a tendency to hide wherever they can, such as in cracks and crevices, and dark areas where there is excess clutter. They love clutter.

Outside they have a little freer reign, but still like to keep out of sight. You will often see a Garden Spider on its web during the day. Humans are really good at knocking down spider webs. Spiders can build webs really fast. You go to bed, and wake up to a spider web that wasn’t there the night before. Black Widow’s have a different kind of web from the beautiful ones that you see, all built symmetrically. The Black Widow’s web is straggly, and course, with no definite pattern. This is because they catch the bigger insects such as beetles. Many of the larger insects are also nocturnal.

There is a whole busy life going with the insects, rodents, and spiders, as we sleep. As time progresses, as in evolution, some types of spiders have become diurnal, meaning they are most active in the day. But still, they like to keep out-of-sight. Ultra violet radiation seems to play a big role in these modern times affecting the performance of orb webs. Another reason that spiders like to stay unseen during the day is because their predators, such as wasps and birds are after them. On the average spiders are definitely more active at night.

Where Are The Common Hiding Places For Spiders?

There are many common hiding places for spiders. They like to hide in your home, garage, out buildings, and in your yard. They do not like to be seen. Spiders do not go out of their way to bite people, but many spider bites happen because humans are invading their hiding places and accidentally surprise them. You might accidentally surprise a spider hiding in your storage area amongst boxes, in your closet, in your shoes, and also while you are cleaning up clutter. Spiders can also be accidentally disturbed while you are doing yard work, such as cleaning up leaves, or when pulling weeds. Spiders like to hide in brush piles and in your firewood.

Spiders also like to hide under your bed, and other furniture. Spiders can hide in your work area, and in your tool box. Spiders are more likely to be encountered if there is a lot of clutter. Make sure you can see where you are reaching and feeling with your hands. Also if you have a lot of debris in your yard, spiders can be a problem.

Some places spiders like to hide where you most likely won’t surprise them are in cracks and crevices. Cracks and crevices are usually safe hiding places for them. Cracks and crevices are not safe hiding places for them if a pest control service has been hired to eliminate them. There is no place for them to hide from an expert pest control company.

What Is The Birthing Cycle Of Spiders?

When some spiders mate or court they give off a scent or strong odor to attract the opposite sex. They can actually tell by the scent if the other spider is of the same species and rather the female is receptive to mating or not. Sometimes after mating the female spider will kill the male spider. The male spider will often perform rituals and dancing type movements to exhibit that they are attempting the mating process, so they won’t get eaten by the female spider, which is often larger. Most male spiders have relativity short lifetimes and are lucky to survive at least two copulations. There are exceptions to the short lifespan, such as with the Tarantula, who can live up to 25 years or so, especially if kept in captivity as someone’s pet.

Silk egg cases are made by the female through her weaving abilities, and each egg case can contain several hundreds of eggs. Many species of spiders care for their babies after they are hatched. They will carry them around and give them food, such as minute insects.

There is an intermediate interception of the sperm from the male spider where he does not actually put it in the female’s body. The male spiders make sperm webs, just like the female spider makes her silk egg case, as mentioned earlier. The male spider puts his sperm on the sperm web where it is intercepted by the female. The birthing and reproduction cycle of spiders is rather complex, but very productive.

What Is The History Of Spiders?

The history of spiders has been evolving for a long time. There are more than 100,000 species of spiders. Their ancestors, some 380 million years ago, evolved from Chelicerates. These are crab like beings. The Chelicerates, whom are arachnids, are the first true spiders. Spinnerets and silk secretion came at a later date. Otherwise, there were not always spider webs as we know them now.

The oldest known spider type creatures, or land arthropods, are known as Trigonotarbids. They also had eight legs as the spiders of today, and the same pedipalps (almost like an extra pair of legs) near their mouth parts, used as sensory organs. Trigonotarbids are not considered true spiders, even though there are many similarities shared.

The actual species that evolved into the spider, and its close relatives, as we know them today, all over the Earth, is the Tetrapulmonates. The very oldest true spiders are about 300 million years old. They are from the Carboniferous Age.

The spiders we know in North America most likely belong to the group of primitive spiders, called Mesothelae. It is pretty sure that these were ground spiders, which lived close to the Earth. These had their spinnerets underneath their abdomen, instead of at the end like the spiders of today. Their silk was most likely used as a covering for their eggs, instead of the beautifully contrived spider webs we see in this day and age. Except for the Black Widow she does not have a pretty web. Yes, times have evolved in the interesting history of the spider as we know it today.
