Natural  insecticides include orange oil, cedar oil, freshwater food-grade [[Diatomaceous earth]]. The latter rightly applied, can slowly work to control or kill bed bugs by cutting them as they travel, often resulting in their death by dehydration.  Silica aerogel (a synthetic desiccant dust) mixed with chemical insecticides has reported to be highly effective,<ref>http://www.mypmp.net/bed-bugs/bed-bugs-are-dusts-bed-bug-bullet</ref> especially  when combined with a blend of bed bug alarm [[pheromones.]]<ref>[http://www.bioone.org/doi/abs/10.1603/033.046.0323 Journal of Medical Entomology, Addition of Alarm Pheromone Components Improves the Effectiveness of Desiccant Dusts Against Cimex lectularius]</ref> Lower humidity is recommended for using diatomaceous earth, and the manner of application as well as the source of diatomaceous earth can be a deciding factor in how well it works, and more research is needed to establish its effectiveness.<ref>http://newyorkvsbedbugs.org/2010/01/11/australian-de-trial</ref>

=====Pesticide resistance=====

===Pesticide resistance===

Some studies have concluded that resistance to ''many'' of the chemical pesticides currently used is increasing in some bed bug 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 a report from the University of Kentucky College of Agriculture, some of the latest “super bed bugs” can survive for up to 16 days after being directly sprayed with currently used pesticides designed to kill insects immediately.
