Craig from Montevallo, Al writes
If earthworms come into contact with the area treated with Bayer Advanced Complete Insect Killer For Soil & Turf, they could be affected the same way other insects will be affected but are pretty protected with the mucus on their bodies. 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.
