Controlling insects on a lawn can make it a safe and visually appealing place.
Lawns frequently suffer from insect pests, which can harm the lawn's appearance if you don't control the problem. Identifying the problem helps homeowners decide what type of pesticide to use. Lawns suffering from insect infestations show signs of wilting, dead areas or defoliation, and some insects bite humans and pets. Does this Spark an idea?
Grub Killer
Various insect pests, such as the chafer and the Japanese beetle, feed lawn root systems during their larval stages. White grubs are most active during the midsummer, but grub damage often does not become apparent until the fall. Patchy areas will lift up when you pull them. Control grubs in mid-July to August when they actively feed, using lawn insect killers that contain imidacloprid, halofenozide or alofenozide. Newer formulations provide successful control when applied in June and July. Check the label to determine the best time to apply.
Red Imported Fire Ant
In the 1930s, the red imported fire ant (Solenopsis invicta) was accidentally introduced into the United States from South America. The ant has a forceful character and will confront humans or pets. The ants can inflict a painful sting. The ants build mounds that measure up to 3 feet in diameter and more than a foot tall, housing more than 100,000 ants. Control the ants with broadcast insect killers that contain hydramethylnon, abamectin B1, fenoxycarb or boric acid. Insecticide drenches, granules or sprays applied to the mound may also help.
Chinch Bugs
Chinch bugs (Blissus insularis) can cause extensive damage to St. Augustine lawns if not controlled quickly. The insect also infects bahia, zoysia, Bermuda and centipede grass varieties. Infected lawns show circular patterns of brown. Damage usually occurs in hot, dry weather. The bugs prefer to eat in the warm sunlight. Control chinch bugs by apply insect killers that contain acephate, diazinon, chlorpyrifos or synthetic pyrethroid. Use pesticide sprays or granule spreads.
Chiggers
Chiggers usually occur in areas of tall grass or woody regions, but they often wander onto lawns. Once on a lawn, they look for humans or pets. Chiggers enjoy sucking the liquefied tissue of victims. The insect's mouth injects a fluid into the feeding site that helps break down the cell tissue, so the insect can better swallow it. The bite location usually swells and itches. Control chiggers by applying granules that contain cyfluthrin, bifenthrin or deltamethrin.
