I planted 65 Arborvitae trees in my yards last year. Moles have taken over my yards completely. They especially like to hang around my trees. (probably cause i water them a lot). Will spreading Grubex around the trunks/roots be harmful to my young growing trees?
Grubex would not be harmful to trees as it is only an insecticide that works as a contact kill on existing grubs and plant damaging insects the first 24-48 hours after you apply it. That being said, trying to eliminate grubs from your lawn will not work to eliminate moles. Please see our Mole Control Guide and the appropriate treatment methods to eliminate them from your lawn in a more direct fashion.
