Pest Identification: Chinch Bugs
These turfgrass pests can do extensive damage to your yard quickly. Chinch bugs have piercing parts in their mouths that attack and suck grass stems and crowns dry, making your yard look like it suffers from severe drought damage. Their devastation doesn’t stop there. They also release a toxin into the grass blade that prevents the plant from conducting water, causing it to yellow and wilt even after the bug has left the area. Chinch bugs can quickly kill entire patches of your lawn, if not your entire yard. Drought, or other yard stresses, can make the damage worse.
Appearance and Behavior of Chinch Bugs
There are two main types of chinch bugs, the hairy chinch bug and the southern chinch bug. The hairy chinch bug attacks turfgrasses growing in northern states and are the chinch bugs the most common to New England.
Adult chinch bugs have black bodies, reddish legs, and distinctive white triangle patterns on their wings when folded. They range from ⅛ to ⅙ inch in length. Chinch bugs overwinter as adults in protected areas, such as thatch, tall grass, or plant debris, and begin laying eggs in the spring.
Females deposit between 300 to 500 eggs on roots, lower leaves, and stems. Pink or red nymphs emerge from the eggs anywhere from seven days to 30 days, depending on the temperature. In some years, up to five generations may develop in one year. Once they hatch they immediately begin to suck the plant's sap. Recently hatched chinch bugs grow rapidly and molt five times before they mature. Their color darkens as they mature.
Chinch bugs are commonly found in the sunny parts of a yard. They move from lawn to lawn by walking and can even be seen crossing sidewalks or driveways on sunny, warm afternoons.
