Are you afraid of cockroaches?
If so it’s all ok - after all, these creepy crawlies send a chill down just about everyone's spine. Their rigid exoskeletons, eery moving antennas, thorny legs, and scurrying movements are all very intimidating and scary. Let alone when they decide to launch out and fly at you. It’s enough to keep you awake at night. Perhaps as you have contemplated your own fear of these denizens of the dark places you may have asked yourself this question - “Why are cockroaches so hard to kill?"
I will attempt to shed some light on this question.
General Information About Cockroaches
Cockroaches, along with spiders, ants and rodents are the most common types of pests in many homes and other buildings. As the sun goes down and we lay down to sleep, they begin to sneak out of cracks and crevices and wander around our homes in search of food - and they find it in the kitchen, trash bins, storage places, drainage, and sewers.
Living with cockroaches in your home is unfortunate because they actually have quite filthy habits and can produce a nasty smell. In fact some people can even become allergic to their scent through continued exposure. It may surprise you to learn that cockroaches also carry bacteria or fungi with them that may cause diarrhea, dysentery, typhoid fever and cholera.
There are around 3500 species of cockroaches but only a few are considered as pests because of their desire to cohabit with people. Some of these pest species are:
Why Are Cockroaches So Hard To Kill?
But back to our original question - why are cockroaches so hard to kill?
It basically comes down to 4 main reasons.
Cockroaches are really good at hiding. This allows them to survive even if they are continuously attacked by humans. Cockroaches breed and hide in the spots of your house where you least expect them to be. They live under the basement, in your garage, in decaying cardboard, unused luggage, boxes of books, under kettles and microwaves, under dishwashers and washing machines and even up in your roof space.
By remaining well-hidden cockroaches ensure that their offspring grow into maturity. This means that without intervention, the cockroach population in your house will never decrease.
That’s right! Cockroaches will eat almost anything that they can get their mandibles on. They eat the food we like such as bread, meat, biscuits and fruits. But they also eat all kinds of decaying matter that even other insects find unappetising. Sometimes, if they fail to find food in the house, they may even resort to eating fabric, soaps, cardboard, bookbinding, toenails. and even other cockroaches.
Studies show that cockroaches learn to avoid traps. Researchers discovered that traps and baits only work on cockroaches if they are newly installed. As time goes by, the effectiveness of the traps and baits decrease because cockroaches learn to avoid and somehow foresee the impending danger and avoid it.
Cockroaches are very hard to kill because of their strong immune systems. The immune systems of cockroaches are designed to destroy microbes and fungi that kill other insects through natural disease and fungal infection, which in turn gives cockroaches long lifespans allowing them to produce many offspring.
