Why Do Cockroach Die on Their Back?
WouterHave you ever noticed that when a cockroach is about to die, it often falls on its back? It’s a common phenomenon, but it’s also extremely disgusting. Here are some possible reasons. One, the roach probably received a toxin sprayed around the house, which is meant to kill disease vectors on the legs. This, in turn, messes with the cockroach’s nervous system and internal circuitry.
Cockroaches are not usually seen in the daylight, but if you find a cockroach in your home, you should not take it lightly. They carry a variety of diseases and are dangerous to humans. In addition to spreading disease, cockroaches also have an instinct to play dead. They may not be able to move their head, but they will move their body and legs for several hours, even days or weeks.
Another reason cockroaches die on their backs is because of a chemical insecticide. Insecticides affect the nervous system and cause muscle spasms. This makes cockroaches unable to right themselves on smooth surfaces. This makes them vulnerable to predators and other dangers.
During the process of death, the cockroach has difficulty regulating its body temperature. A common commercial insecticide acts on the nervous system and causes insects to convulse and kick their legs uncontrollably. Once they reach this point, they’re unable to turn over, and their legs are pointing upwards.
