Will applying insecticides to kill grubs help control moles?
One of our biggest frustrations with moles is the perennial misinformation that an insecticide application to kill grubs will solve the mole problem. This is the “lie that will not die.” Forty years ago, it might have been true that an insecticide application would discourage moles because back then, the insecticide ingredients being used were highly toxic to people, pets, and wildlife, but they were especially toxic to the “Mole Main Meal” – earthworms.
All pesticides that were highly toxic to earthworms were discontinued or banned long ago. Insecticides available today do not kill earthworms; therefore, the white grub treatment does NOT remove the mole food source
