According to the University of Florida IFAS Extension, the Southern chinch bugs can rapidly damage a lawn. The patchy areas of yellowing grass are usually the first indication of chinch bug activity. Uncontrolled chinch bugs will rapidly kill the grass which will begin to appear brown. Homeowners ofter mistake the damage for drought.
These damaged areas of the grass are generally circular in shape. They expand outward as the insects move from dying grass into healthier grass. These southern insects attack the open sunny areas first. Areas of the lawn that are under drought stress are also a target. Consequently, periods of drought cause elevated chinch bug abundance and damage. The thick thatch areas of the lawn provide refuge from natural enemies and environmental conditions.
t’s easy to determine if you have chinch bugs. Simply part the grass where the brown damaged lawn meets the green grass. Then look for small insects that are damaging the turf.
Although adults can fly, they preferentially walk from plant to plant, which also makes them easier to detect. Chinch bugs love the thatch area of the grass. But, when populations are high, you will see them resting on leaf blades or crawling across the lawn. Although these insects are small, there are a few easy methods for detecting them in a lawn.
Some causes for chinch bugs is mowing your grass too short or improper irrigation. This will dry your lawn out create the perfect condition for chinch bugs to begin their damage.
