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.

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.  Spot treatment of bedbugs with chemical formulations can make matters worse by allowing them to disperse and or develop resistance to the insecticide used.

Studies indicate that resistance to many of the chemical pesticides currently used is increasing in some bedbug populations in many areas of North America.<ref>http://www.faqs.org/periodicals/201006/2054573271.html</ref>  According to research at the University of Kentucky College of Agriculture, some of the latest “super bedbugs” can survive for up to 16 days after being directly sprayed with currently used pesticides designed to kill insects immediately.  Bedbugs have a cuticle on the outside of their body that is almost impenetrable to many insecticides used today, therefore the bugs do not pick up dried residues very well.  Bedbugs developed resistance to DDT  in 1950s, and then to its successors such as organophosphates like diazinon and malathion which were being used to clear up remaining infestations.<ref>http://www.earthfiles.com/news.php?ID=1768&category=Environment</ref> DDT resistance can lead to pyrethroid resistance, as both pesticide classes act on the same target site.<ref>http://newyorkvsbedbugs.org/2010/01/21/kdr-pyrethroid-resistance-widespread-in-u-s-bed-bug-populations/</ref>

Normally, it takes about ten years testing on rats and dogs for mutagenic effects and costs about $200 million for such a chemical to be approved by the EPA.

Bed bugs have not shown resistance to a relatively new material, ''chlorfenapyr''.<ref>http://newyorkvsbedbugs.org/2009/11/01/basfs-bed-bug-prevention-pitch/</ref> However, chlorfenapyr may require ten or more days kill the bugs, during which the bugs may still be active and females may wander and deposit viable eggs in other locations. Currently, microencapsulated materials such as contain esfenvalerate or lamba-cyhalothrin may offer the best rapid reduction of susceptible populations.<ref>http://ento.psu.edu/extension/factsheets/bedbugs</ref> Also reported effective against some pyrethroid-resistant bugs were two pyrethroid-based dusts, as well as diatomaceous earth.<ref>http://newyorkvsbedbugs.org/2009/05/22/finally-researchers-on-the-efficacy-of-dusts/</ref>
