What are Chinch Bugs?

Chinch Bugs (pronounced sinch or chinch) are small insects, which live in and feed on lawn grasses. They live above the soil and feed on living grass plants by means of a piercing mouthpart called a stylet (similar to a mosquito). The insect inserts its stylet into the leaves, stems or crowns and sucks the juices out of the plant. The damage looks quite similar to drought symptoms and many Weed Man Denver, CO customers mistakenly assume that the lawn needs only water to restore its lush green appearance.

Life Cycle

To control an insect population we must understand its habits and its life cycle. Chinch bugs survive the winter as adults seeking shelter from the cold and snow under shrubs, hedges and leaf litter. In the latter part of the spring (about the time the forsythia blooms fall or when Weed Man is treating your lawn for dandelions) they come out of hiding and venture into the lawn. Here they will mate and the females will seek a hot dry location in which to lay their eggs (usually a south-facing, sloping hillside). Chinch bugs like hot dry locations.

The adult female will lay approximately 250 eggs in the lawn. In about 3 weeks time the eggs begin to hatch and the young chinch bugs (nymphs) begin feeding. Two or more generations can mature each season. The eggs are laid very close together so that when the eggs hatch and the young begin feeding, small patches of small grass begin to appear. If a homeowner ignores the problem or is unaware of it the patches get bigger as the insect matures and seeks food further a field. Chinch bugs can totally ruin a lawn in 3 weeks if no control methods are taken.
