I'm planning on applying the insecticide to control mosquitoes, but don't know how it will effect my earth worm population.
If earthworms come into contact with the area treated with Onslaught, they will be effected the same way other insects will be effected. Typically earthworms tend to stay several inches below the surface and remain hidden away from insecticide applications but if they do end up surfacing in treated areas they will be eliminated. For the most part insecticides are not selective.
