Pest Patrol: Summer

White Grubs: Peel back a bit of lawn starting in mid- to late August, when they chew on grass roots, destroying the roots' ability to absorb water. Damaged patches will roll up easily, like carpet.

Treatment: Once soil reaches 70 degrees F, use a pump sprayer to spread beneficial nematodes (microscopic worms) mixed in water.
