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>
