I want a longer residual for bedbugs. Can I mix with DE and spray it without water?
Tempo Ultra WSP should only be mixed with water and applied to indoor crack and crevices. It is labeled for bedbugs but should not be the only product used for a bedbug infestation alone. First, using powders or dusts alone will not effectively get rid of a bedbug infestation. Insecticide dusts and powders take about a week to actually kill insects and in that time the bedbugs can still bite and reproduce. We offer bedbug kits that contain all of the different products you need to eliminate bedbugs and retreatments should be done every 7-10 days until you do not receive a bite for 30 days. Most dusts only need to be applied once every few months and unless you vacuumed. We also highly recommend using mattress and boxspring encasements to help eliminate bedbug infestations. These bedbug proof covers will trap existing bedbugs and eliminate hiding places and make inspections easier. How to Get Rid of Bedbugs Article
