Bedbug Treatment
It seems several of the pesterer controllers don’t have any or very little expertise treating the hemipteron. They still treat with ineffective pyrethroids that tend to repel the hemipteron instead of kill them. as a result of the hemipteron is repelled by the treatment they are doing not receive enough of the insect powder to be effective. to boot, what’s effective has very little residual activity and ends up in re-infestation.
Probably, the largest treatment failure for bedbugs is that not all of the insect’s habitats are found and known before treatment.
