What is the strongest most effective chemical to kill bed bugs?

I have used temprid SC for about 8 treatments. most bugs appear to have been killed I am still seeing some new activity we recently moved I don't know if I have disturbed colonies that were dormant or if I had inherited some new ones. from what I have read it may be wise to switch to another poison or use two poisons I am almost out of time. I need to buy some more so I need some direction please as for proneness please believe me I have been extremely thorough. I have also used two packs of the nuvon strips in blue tubs. the items in the blue tubs have been in there for over a month. I have some clothing in black plastic bags that have not been treated yet but have not been opened yet either. before I revisit the tubs for the bags I wish to make sure I have an all clear in my new house.


While, Temprid SC is the best liquid insecticide to use for treating bedbugs, it will not treat an infestation alone. Please take a look at our Bed Bug Kit #2 or Bed Bug Kit #3 . These kits contain all the necessary products to fully treat and eradicate a bedbug infestation.

Temprid SC or Fenvastar EcoCap is mixed in a 1 gallon sprayer and applied around the perimeter of the room(s) along baseboards, floorboards, headboards and walls.

Cimexa Dust is applied to wall voids, inside box spring, crack and crevices where bedbugs can't go (behidn picture frames, under furniture, cracks of dresser drawers, join cracks and hollow tubing of bed frames, etc) - Only need a fine coating, do not over dust. Using 2oz of dust per 100sq ft, 1/4oz of dust to each wall void. How to Apply Dust Article here

Bedlam - Spot Treatments on mattresses, upholstered furniture, drawers, bed frames, carpeted areas, and curtains. Provides contact kill and leaves 2 week residual.

Steri-Fab - Alcohol based contact kill that does not leave any residual after it is dry making it safe for comforters, mattresses, sheets, cushions, dog beds etc.

Bellow Hand Duster - used to apply dust to crack & crevice, under baseboars, box springs. Fill 1/2 way with dust, not to the top b/c it needs air to pump the dust out.
