Is Imidacloprid dangerous to Earthworms when applied to the soil as a systemic on turf?

I am applying Imidacloprid in mid-Summer to treat for grub larvae. I don't want to adversely affect the underlying earthworms in the lawn's soil

Answer:

Earthworms have a protective mucous on their bodies that helps protect them from pesticides and they live well below the surface of the soil and pesticides cannot penetrate that far down to be effective. The active ingredient in Dominion 2L Termiticide Imidacloprid only has been shown to have acute toxicity to earthworms. In no case did a long term effect on earthworm populations occur, so this product will not harm the earthworms on your property.
