The late summer and early fall for the northern United States continues to stay warm and chinchbug damage remains obvious.  At  this time symptoms appear like drought injury, but when water is added the turf fails to green-up.  Damage is present under trees and through the lawn.  Chinch bugs overwinter as adults and then lay eggs in early spring.  The eggs hatch and the nymphs begin to suck the juice out of the leaves.   It may take 30 to 90 days for the nymphs to reach adulthood.  Usually there are two generations per year.

To detect the presence or absence of chinch bugs spread the turf on the outer edges of the damaged area.  They are not normally found where the turf is already severely injured or dead.  The adults are small appearing black with very short whitish wings.  The chinch bugs also move slowly.  Injury will be most prevalent in Kentucky bluegrass with minimal damage in perennial ryegrass and tall fescue.
