According to a study carried out on Ortho Home Defense, it contains a chemical bifenthrin that is considered relatively safe and kills off bugs that pyrethroid-based insecticides can’t. It is also effective against bed bug eggs and larvae.12 It should be sprayed as a spot treatment in any crevice where bed bugs can reside.

"In the past, bedbugs have repeatedly shown the ability to develop resistance to products overly relied upon for their control. The findings of the current study also show similar trends in regard to chlorfenapyr and bifenthrin resistance development in bedbugs," study researcher Ameya Gondhalekar, research assistant professor at Purdue's Center for Urban and Industrial Pest Management, said in the Entomology Today statement. "With these findings in mind and from an insecticide resistance management perspective, both bifenthrin and chlorfenapyr should be integrated with other methods used for bed bug elimination in order to preserve their efficacy in the long term."

Bedbug infestations seem to be increasing around the world at an alarming rate, possibly due to insecticide resistance. [1] Resistance to pyrethroid insecticides is already widespread in the United States. The bedbug occurs in aggregations when conditions are favorable, but the arthropods disperse when conditions are unfavorable. [2] Active female dispersal can potentially lead to treatment failures and should be taken into account when using control methods.

Often, bedbug bites are clustered along lines usually following arms and legs. Theories range from the idea that bedbugs are feeding along blood vessels to the idea that bedbugs remain with their bodies touching the bedding while they feed, and the bugs are left to feed only along lines where the skin is touching the bedding in just the right manner.


To get rid of bed bugs in a mattress, use an aerosol spray labeled for bed bug treatment, such as Bedlam Aerosol Spray, and spray or mist the insecticide onto the mattress. Focus on the seams, tufts, and folds of the mattress and spray until the mattress is damp. Allow mattress to dry before remaking the bed with freshly laundered sheets that have been run through a dryer on high heat.
Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building.
