Cockroaches come into your house primarily because of two things: food and water. Most species of cockroach prefer the great outdoors to call their home, but other roaches, particularly the American cockroach, prefer the sanctity of your home where they’ll find shelter from the sun (and the elements), and most definitely food and water. Finding a regular supply of food and water is definitely high on their list.
They can come through your pipes and drains, windows, doors, the gaps and cracks on your walls, vents, and a number of other places you won’t even think to look. Once they establish that yes, your home is a nice, cozy place, you best believe they’ll set up shop there. They may call the rest of their family and friends in, or give birth to a whole brood of fresh roaches right under your nose.
What are these sources of food? Well, roaches can eat almost anything. They get most of their nutrients from the bacteria living on their bodies, so they’re not exactly concerned with how healthy their food is – they’ve been known to eat the most unexpected things like toothpaste and even glue (like the glue on the back of stamps). They can eat dead skin flakes, eyelashes, fingernails – they prefer dead things because their jaws are actually quite weak.
If they have their pick, of course, it’ll be a wide array of choices from your garbage bin. So if you want to make your place inhospitable from roaches, keep your garbage properly contained and disposed of in a timely manner. Don’t leave dishes on the sink overnight either, because they will love to clean off those plates if you give them the opportunity.
Roaches are nocturnal creatures, and during daytime, they prefer to find dark, damp places to settle in. Get rid of possible hiding places in your house such as old storage boxes, which are also great places for roaches to lay their eggs in. Fix leaky faucets and make sure you don’t have standing water where you don’t want it (which can also serve as a breeding ground for mosquitoes). You may also want to wrap insulation on pipes that condense, as that can also serve as a regular source of water for roaches – remember, they can live for a month without food, but only for a week without water.
Seal or caulk gaps and cracks on your walls, especially if you have any gaps between the wall and any piping. Invest in screens for your windows and any outside vents, and use weatherstripping on windows and doors.
Also remember that cockroaches are a great source of food for a number of other pests like spiders and cockroaches, so if you have them, there’s a good chance these other pests will want to set up shop in your home too.
If you’ve tried to get rid of cockroaches on your own but still find them in your house after a day or two, then it may be time to call a professional pest exterminator like Watchdog Pest Control for a guaranteed pest-free home.
