Natural  insecticides include orange oil, cedar oil, freshwater food-grade [[Diatomaceous earth]]. The latter rightly applied, can slowly work to control or kill bedbugs 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>

In addition to normal measures such as laundering, it was DDT, followed by malathion, diazinon, etc. was effective in largely eradicating bedbugs in the recent past, as one thorough application of these older insecticides typically worked as bugs succumbed after crawling or resting contact with previously treated surfaces. As most of today's sprays lack similar residual potency (and with many also being repellent), desiccant (drying) dust formulations may play an increasing role in eliminating and preventing bedbugs in harborage areas.<ref>[http://www.mypmp.net/bed-bugs/bed-bugs-are-dusts-bed-bug-bullet ''Bed Bugs: Are Dusts the Bed Bug Bullet?''] Pest management professional, May, 2009</ref>

Repeat treatments with any 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.  Fogging is not advised, as besides the health risk to humans, they are considered to be less effective, and most contain pyrethroids, which has an associated excitatory flushing effect and by spraying into a space rather than harbourage, bugs are likely to disperse and can spread an infestation.<ref>[http://bedbugger.com/2007/05/30/bombs-dont-work-on-bed-bugs-citation-anyone/ Bombs and foggers don’t work on bed bugs and can make them worse]</ref>
