Abstract

Bed bugs may be severe pests in poultry houses, especially broiler breeder houses, leading to stress, anemia, and lowered egg production in the birds. Insecticides are important tools in managing these pests; however, efficacy data for many commercially available products is lacking. This laboratory study evaluated 8 insecticides (5 traditional residual products and 3 natural or “green” products) against bed bugs collected from a poultry house in Mississippi during August 2014. Invader® (propoxur), Ravap® (rabon and vapona), and Cimexa® (silica gel) killed 100% of bed bugs when exposed to ceramic tiles sprayed with the products 24 hours earlier. Interestingly, Ravap®(rabon/vapona combination) is labeled for use inside poultry houses even with birds present. Cimexa® is a non-toxic powder which desiccates bugs. Tempo® and Suspend® (pyrethroids) killed 73% and 93% of bed bugs, respectively, indicating that the poultry house field strain used in this study was likely not pyrethroid resistant. The organophosphate, Durashield® (chlorpyrifos), also showed good efficacy against poultry bed bugs, killing 96% of the bugs in this test, but cannot be used in the presence of birds. Alpine dust® (diatomaceous earth/dinotefuran) and EcoExempt® (phenethyl propionate/soybean oil/clove oil), both considered natural products, only killed about half of the exposed bed bugs in this study (46% and 45% control, respectively).
