I used Viper and an IGR in a 1 gal sprayer and I'm not seeing as many, but I am still seeing some. I was wondering if this kills on contact or if they take it to the nest.
The cypermethrin active ingredient in Martins Viper Insecticide Concentrate is picked up in the residual, and carried back to the nest. It works by affecting the pests' central nervous system.
