Focus On Proper Lawn Care

Since chinch bugs fly, it won't be possible to prevent them from landing or laying eggs in your turf. However, there are ways to prevent damage and a large chinch bug infestation, focusing on proper lawn management to keep your lawn healthy.

Step 1

Cultural Control

(Proper Lawn Care)
As with almost any lawn pest, weed, or disease, a strong and healthy lawn can better fight off and withstand pressures from pests. Following a lawn care schedule will help to ensure you're doing everything you can to keep your lawn at its best, including:
  • Mowing grass to about 2-2 1/2 inches
  • Fertilizing at the proper amounts and timing, careful to avoid over-fertilization
  • Irrigating lawn in times of drought is important, but overwatering or improper watering can make your lawn weaker.

Step 2

Manage Lawn Thatch

Excess thatch causes problems when it comes to chinch bugs.

Thatch, which is a buildup of dead and living grass and other organic matter, and it creates a perfect environment for chinch bugs to feed and live.

An excess thatch also inhibits your control efforts against chinch bugs, since the thatch will bind up the chemicals in your control products, making them far less effective.

To control excess thatch, you can use a vericutter machine to vertically mow the thatch in your turf. Proper lawn maintenance will help you avoid thick thatch in the future.

Step 3

Preventative Control Products

If chinch bugs are a consistent problem year after year, a preventative chinch bug pesticide can be applied in early spring before eggs hatch. May is a good target month, but talk to your local extension office for a more accurate date to apply a preventative pesticide.
