Question: What can you tell me about using milky spore and/or nematodes to control the grubs in my lawn? I'm hoping to deter the skunks and voles that have been digging it up.

Answer: Beneficial nematodes are naturally-occuring microorganisms; they feed on the larvae of many insect pests, including Japanese beetle grubs, root weevils, and cutworms. However, they will not harm earthworms or other beneficial creatures (including people!)--they are very specific to their lavae prey. Milky spore disease is caused by the bacteria Bacillus popilliae and is used to control Japanese beetles and some strains of European chafer grubs; the disease does not infect people or pets. Follow label instructions carefully for the proper timing and amount to apply.
