Mechanical Removal
When pests are visible and large enough, removing them via the "pick and squash" method is an option for the non-squeamish. Try the following on insects you cannot see.

1. For chinch bugs: Prepare a soap drench with 2 tablespoons of dishwashing liquid per 2 gallons of water in a watering can. Thoroughly water an off-color patch and then cover it with a flannel sheet. Wait fifteen minutes; then scrape clinging bugs off the sheet and into a garbage can, and close the cover.

2. For sod webworms: Drench the target areas with soap solution and watch for the worms to climb up from the thatch layer. Rake them up and dispose of them in the garbage or in water.
