Chinch bugs can wreak havoc on your lawn and can be very difficult to control. They can also enter your home in great numbers. These tiny pests can be identified by their black-and-white markings and small wings, which extend halfway down their abdomens.
The chinch bug can also be identified by the damage they cause to your lawn. Yellowish-brown patches of grass along sidewalks, curbs and driveways are signs of chinch bug infestations.
Chinch bugs can seriously harm St. Augustine grass, which is typically found in the southeastern U.S. The chinch bugs feed on the grass by piercing the stems and sucking out its juices. They then inject a toxin that causes the grass to turn yellowish or brownish.
Keeping your lawn healthy can reduce chinch bug infestation. Keep thatch to a minimum and aerate. Water properly so the lawn is neither too wet nor too dry. These methods will help keep chinch bugs from destroying your yard.
