How Long Do Cockroaches Live After Being Sprayed With an Insecticide?

Cockroaches can migrate into your home even after you’ve applied a cockroach-killing insecticide. Their guts are full of pathogens that can cause diseases. Even if they don’t have an active immune system, roaches can spread harmful germs by walking on clean surfaces and doing “number two” anywhere.

If you have ever witnessed a cockroach submerged in water, you might have thought that it’s dead, but you were wrong. Despite their open circulatory system, they are able to survive for up to half an hour in water. They also hold their breath so they don’t get too dehydrated.

Cockroaches are a crucial part of our ecosystem. They have six legs and a bulky body, so they are prone to falling over and dying. When killed, they don’t migrate to the center of the room. They roll onto their backs. When they die, they lose muscle control and are unable to straighten their legs, causing them to fall.

However, cockroaches can live up to two weeks after being sprayed with an insecticide. Although the spray doesn’t fully poison them, they can latch on to something and escape. It’s also possible for them to close their airways, preventing the poison from reaching their internal organs. In addition, their exoskeleton is strong and resistant to chemicals.
