I've marked all the cicada killer holes in my yard (89). I bought Dione dust because it will kill the larvae but it's going to rain all week and that makes Drione dust ineffective. So if I use Delta Dust instead, will it also kill the larvae?
Delta Dust Insecticide is actually the most recommended dust for cicada killer wasps holes as it is 100% waterproof so will still work when wet.
