[[Insecticide]]s known to kill bedbugs include [[deltamethrin]], a synthetic pyrethrin, one of many pyrethroids,  . Other chemicals include benseneacatate, chlorfenapyr, chlorpyrifos, cyfluthrin, esfenvalerate, fencalerate, lambda-cyhalothrin, permethrin, phenothrin, propoxur and resmethrin, not all of which are EPA approved. <ref>[http://www.bedbugbattleplan.com/content/view/42/33/ Bed Bug Insecticides]</ref> Isopropyl alcohol also works as a contact killer, as do certain  insecticides while others also provide some degree of residual effectiveness.< Insecticides are classified according to their application method: Crease and Crevice, Indoor Surface, Indoor Space, and Fumigation. <ref>http://www.bed-bug.org/insectisides-for-bed-bugs/</ref>

Natural  insecticides include cedar oil, [[Diatomaceous earth]] as well as slica and quartz. The latter three can slowly work to control or kill bedbugs by cutting them as they travel, resulting in their death by dehydration.  

Natural  insecticides include cedar oil, food-grade [[Diatomaceous earth]] as well as slica and quartz. The latter three can slowly work to control or kill bedbugs by cutting them as they travel, resulting in their death by dehydration. However, diatomaceous earth is less effective at higher humidities, and the source of the diatomaceous earth can be a deciding factor in its effectiveness.<ref>http://newyorkvsbedbugs.org/2010/01/11/australian-de-trial</ref>

An additional insecticide is one which does not actually kill bedbugs, but instead it works to prevent reproduction by disrupting the development of immature bedbugs, resulting in being unable to reproduce. This process takes longer but it can ensure an eventual end of the infestation, if contact with all bedbugs is made, but usually this chemical is used in conjunction with other insecticides.<ref>http://www.bed-bug.org/insectisides-for-bed-bugs/</ref> Repeat treatments with any legal insecticide are advised and are almost always necessary. Inhalation of all  insecticides is to be avoided. Spot treatment of bedbugs with chemical formulations can make matters worse by allowing them to disperse and or develop resistance to the insecticide used.
