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://newyorkvsbedbugs.org/2010/01/21/kdr-pyrethroid-resistance-widespread-in-u-s-bed-bug-populations/</ref><ref>http://www.faqs.org/periodicals/201006/2054573271.html</ref>  This Resistance is genetically conferred to subsequent populations which then show resistance to other chemical tools within the same class of chemistry. Thus the problem involves all pyrethroids and is likely only to get worse.<ref>http://termidorpartners.com/store/Downloads/BASF-626-Bed-Bugs-Guide.pdf</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 the dried residues of such very well.  Bedbugs developed resistance to DDT in the 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 possibly 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>
