Recent advances in genomic and post-genomic technologies have facilitated a genome-wide analysis of the insecticide resistance-associated genes in insects. Through bed bug, Cimex lectularius transcriptome analysis, we identified 14 molecular markers associated with pyrethroid resistance. Our studies revealed that most of the resistance-associated genes functioning in diverse mechanisms are expressed in the epidermal layer of the integument, which could prevent or slow down the toxin from reaching the target sites on nerve cells, where an additional layer of resistance (kdr) is possible. This strategy evolved in bed bugs is based on their unique morphological, physiological and behavioral characteristics and has not been reported in any other insect species. RNA interference-aided knockdown of resistance associated genes showed the relative contribution of each mechanism towards overall resistance development. Understanding the complexity of adaptive strategies employed by bed bugs will help in designing the most effective and sustainable bed bug control methods...

The good news is that the Masked Hunter (a member of the assassin bug family) is a natural predator of bedbugs...
...the bad news is that Masked Hunters are natural predators of bedbugs :-)

This reminds me,
The illegal invasion brought on an invasion of bed bugs in the border states and those annoying critters are real hard to get rid of (fortunately Dems haven't figured out how to get them to vote yet.)
This should be added to the conditions of 'amnesty reform': A comprehensive bed-bug check.

Amen. They had malaria, polio, bed bugs, and everything like that all but wipe off the planet in 1958 and that was too good for them.....
To: Rides_A_Red_Horse
Now that would be a bit of overkill! Heck, why not just use a nookular bomb? If you are going for overkill do it with style!

The bed bugs did not evolve enough to survive what my mom had in store for them.
Once every summer, she would have all the bedding and cot frames placed on the top level terrace of our house in 100+ degree heat with the sun blaring down. Any bugs alive were flying out of there and were laying dead upside down after a few feet of travel.

Dust off and nuke em from orbit. It’s the only way to be sure.

” Undocumented” bed bugs....

Take away their beds and those bugs will go home :)
