Chinch bugs are small sucking insects about 1/8 inch long that drink the juices inside the grass Mostly in St. Augustine grass. Chinch bugs will leave areas of the lawn injured. To see if chinch bugs are a problem, remove the bottom of a coffee can; place at the edge of the damage; fill with soapy water; if many of these small, black insects rise to the top then you have a problem.

Grubs are some of the most destructive insect pests in lawns. Turf is damaged when the grubs (the larval or immature stages of certain beetles) chew off the grass roots just below the soil surface. The root injury reduces the turf’s ability to take up water and nutrients and withstand the stress of hot, dry weather..
Control: GrubsAway (1.4lbs. to 1.8lbs. per 1,000 sq. ft.)
Mole Crickets are burrowing insects about one inch long. They eat the tender roots of turfgrass and make visible trails, Mostly in Bahia grass and Bermuda grass. Mole Crickets also are food for such rodents as moles.
Control: Mole Cricket Bait with 5% Carbaryl (0.9 lbs./ 1000 square feet)
Sod web worms and Army worms are caterpillars about 1-2 inches long. These caterpillars feed on the blades of grass. The blades of grass will have notches in them if worms are feeding. The adult of these worms is a moth. Mostly in St. Augustine and Bermuda grass. If the lawn appears injured from notches eaten from the grass, the turf should be treated.
