I want to spray my yard for ticks, fleas, and grub worms (Japanese beetles) and I want to be sure that the proper dose of Permethrin won't harm the earthworms.
Permethrin SFR 36.8% is not really selective, so it is possible that it could kill beneficials such as earthworms if they were to come in contact with a treated area.
