What chemical soluton can kill bedbugs?

None at present: They have become resistant to all insecticides.I have no doubt that a feverish search is being made for a chemical that will work.

They are very : Resistant. Declutter entire bedroom & any other effected rooms. Check this site for instructions: http://treatmentforbedbugs.Com/ place all junk in tightly sealed plastic & dispose of it. Wash clothing, linens, towels in hot water. Dry on highest heat - then repeat. Place clean items in a sealed bag to prevent re-infestation. Steam clean what you can't place in drier. Vacuum everything using.
