[[Insecticide]]s known to kill bedbugs include synthetic pyrethroids such as  allethrin, tetramethrin, permethrin, esfenvalerate, bifenthrin, cyfluthrin, cypermethrin, deltamethrin, d-phenothrin, imiprothrin, lambda-cyhalothrin, resmethrin, and tralomethrin. Other chemicals include chlorfenapyr, chlorpyrifos and propoxur, which are not all EPA approved for consumer use due to their hazards to human health. <ref>'Bed Bug Increase Due to Pesticide Regulation?'', University of Illinois Extension, Illinois Pesticide Review, May, 2009</ref><ref>[http://www.bedbugbattleplan.com/content/view/42/33/ Bed Bug Insecticides]</ref>

Botanical insecticides containing natural pyrethrins are sometimes employed, and repel and can “knock down” bed bugs for a some time, but natural pyrethrins deteriorate quickly and fail to provide the necessary residual action which some other materials supply.
