How Do Pesticides Kill Bugs  

     If used correctly, pesticides are effective in increasing food production and eliminating pests and diseases. However, pesticides do have harmful effect on the environment and can prove detrimental to animals, insects and plants. If you have a problem of bugs in your garden, before reaching for a pesticide see if you can use safer alternatives.

     Not all bugs are pest. Most of them are beneficial and prey on other insects. If you use pesticides to kill bugs, you will also be killing the good bugs along with the bad ones. You should use pesticides to kill bugs as a last resort.

      Once you decide to use pesticides against bugs, you should make sure that you read the label carefully so that you understand everything it says. Make sure that the pesticide is for the specific bug you have identified in your garden. Do not think that miticide and insecticides are the same. Miticides are used for mites while insecticides are used for bugs.

      Most pesticides kill bugs by affecting their nervous system. The pesticides interrupt the information being sent by neurotransmitters in the synapses. A chemical is produced by the bug’s body which is used to send information through the synapses. This chemical is known as acetycholine. An enzyme called cholinesterase binds with acetycholine, and does not allow the muscles to get over-stimulated and the muscles are allowed to rest.

     Under normal circumstances, acetycholine in the bug’s body sends messages to the muscles through the synapses. Cholinesterase ensures that the levels of acetycholine stay at acceptable levels. When we spray the bugs with pesticides, cholinesterase is affected and keeps it from binding with acetycholine. This leads to the muscles getting over-stimulated and ultimately leads to paralysis and death of the bug.
