Multiple chemical applications negatively impacts the health of your soil, which is key to a healthy lawn. After a good rain, go out after dark with a flashlight and handpick as many of the cutworms as you can (drown them in soapy water). They don’t like dry soils, so water well in the mornings. Release beneficial nematodes, which will attack the cutworms (given your soil is likely not biologically rich, it may take some time and a few releases to start to establish a healthy population). The moths should be dealt with as soon as you see them: release tricogramma wasps weekly for three consecutive weeks—they will parasitize cutworm eggs. Apply Eco-bran on the lawn surface to attract (and kill) catapillars.
