Bruce from Birmingham, Al writes,
Will Demand CS get rid of wasps around house?
Demand CS is labeled for eradicating wasps. Concentrates are not considered to be contact kills, especially for wasps. Even if you got close enough with a hand pump sprayer, which do not spray that far, the spray would not kill a wasp fast enough. They would die, but not right away. You can spray surfaces so when bees land on the surface they will pick up the spray and die, but they will not die right away. The only product that provides a fast knockdown of larger flying insects like wasps and hornets is Wasp Freeze, which comes in an aeorosl can but it shoots over 15 feet so you can knock them down from a safe distance. Demand CS will leave a 30 day residual to the treated surfaces. Most folks do not want to have to spray down every bee or wasp in a nest with the wasp and hornet spray so they apply a dust such as Tempo Dust or Delta Dust which will knockdown even those insects that usually do not come out of the nest. The nests should be treated in the evening when the wasps are the least active for your safety.
