Hi I'm new to this site (and the caring for a lawn), so forgive if I sound ignorant. We are having trouble with voles or moles? in our St. Augustine lawn. We live in Beaufort, SC (Lowcountry) where this is common. I'm told to spread Talstar to control the grubs that the voles feed upon. I'm apprehensive due to the toxicity it appears to have. The bag doesn't go much into detail on when best to apply it. Any tips, suggestions, advice would be greatly appreciated. Thanks.
