Bed Bugs - The Beat Goes On Too
Thursday February 16, 2012
Question:
We know bedbugs are dificult to treat. We are currently treating a residential single family home where bed bugs were found in 2 rooms and inspected for in every room. We use Temprid at the labeled rates, but after the initial spraying and repeated follow ups every 10 days we are still seeing adult, nymph and egg stages of these critters. The main culprit is a child's wooden bed frame and headboard. Many cracks and crevices are present and breaking down of the bed is not an option. This doesn't concern me as much as the fact that I fan spray the head board, out in the open, on a decorative groove that every 10 days still has live adult bugs collecting there and living in the area where the residual should be. How can they still be there time after time (6 total treatments, full inspection and treatment each time)? What can we do to make the treatment more effective? Could it be resistance? I hear nothing but good results from Temprid by others and chemical reps.

Answer:
I will approach this from several angles, and the first will be the wisdom of constantly applying a toxic material to the headboard of a child's bed. Now, let me qualify that a bit. Temprid is an excellent insecticide composed of 2 active ingredients - the pyrethroid cyfluthrin and the non-pyrethroid imidacloprid. There is nothing wrong with either of these materials, and I suspect that bed bugs confined to a surface in contact with these active ingredients for a long enough period of time is going to die. Yes, The Common Bed Bug demonstrates a VERY high degree of ability to become resistant to most active ingredients, but it is not yet completely immune to them. But, because of this high level of resistance our industry experts still tell us that total reliance on insecticides is probably not the solution to bed bug eradication. And, as you state, 100% eradication must be the goal or the problem will continue.
