Largely found in the South, army worms are known to infest lawns and cause severe damage, all within a few days. During the months of August and September is when they begin to feed on lawns and bermuda grass.
Identification & Signs of Infestation
Army worms are the larvae of moths and are light green or tan in their early stages and dark green or brown in later stages. You can identify them by a series of green, yellow, or brown stripes down their body. They are also approximately 1 ½ to 2 inches in length.
The first signs of an army worm infestation in your lawn are brown patches of turf, which quickly grow bigger. Another sign is usually several birds clustered on an area of turf. But, as army worm numbers grow, the birds are not able to rid you of them completely.
Fortunately, army worms are not capable of damaging your lawn permanently. In the fall, army worms rarely kill grass but can severely weaken it. When identified early enough they can easily be controlled. Although the grass blades may be chewed from their feeding, the crowns are not damaged. Therefore, your lawn will be able to recover as long as you keep the damaged area or areas well fed and watered after proper treatment is given.
