How Do Bug Sprays (Like Raid and Baygon) Kill Cockroaches?

Contrary to popular belief, cockroaches cannot survive a nuclear explosion; however, it is true that cockroaches are more tolerant of certain ionizing radiation than humans. Even so, they cannot survive bug spray, as it consists of powerful neurotoxic substances. Bug sprays or insecticides are chemical compounds that inhibit certain physiological functions. Many classes of insecticides differ in their synthesis, how they affect the pest, and whether they indiscriminately affect all insects or are specific to a particular type or family. Insecticides can be lethal in various ways: some insecticides act as neurotoxins, impairing the nervous system, others target respiration and prevent the insect from utilizing oxygen, while others target the insect’s growth and reproduction.
