How Does Bug Spray Affect Insects?


Most bug sprays work by using an acetylcholinesterase inhibitor. Bug sprays with these chemicals inhibit the body's neurotransmitters signal processing in the brain of the insect and prevent signals from moving properly through the body. Without the appropriate signals to reach members of the insect, it is unable to move.
Acetylcholinesterase is the chemical in bug spray that breaks down acetylcholine. Acetylcholine is needed to transmit the directions from the brain of the insect to all vital organs. Once the insect is sprayed, the chemicals within the body begins, and slowly begins blocking neurotransmitters. As the chemicals within the body begins, acetylcholine is broken, and the bug will start to lose control of his extremities. The signals further deterioration and the bug moves its front legs, they are unable to move again. This process continues as the inhibitor moves further into the body of the insect. As it penetrates deeper, the signals from the brain of the insect is inhibited to reach the vital organs as well. Circulatory and respiratory systems are unable to respond to commands from the brain of the bug and start to close. The insect will lose control of all his motor functions and die quickly.
