Army Worms
Fall Armyworm is the caterpillar form of a moth. They don’t overwinter in Kansas but migrate from Mexico and the Southern States. The females lay eggs in large clusters, and the caterpillars hatch and feed together, migrating in search of fresh grass. The caterpillars can be identified by the parallel stripes running the length of their bodies. In the fall, they are a significant turf pest when they can completely defoliate entire lawns and golf courses, turning them brown. While they generally don’t kill established lawns, they may if the populations are high enough.
Since the fall armyworm is a caterpillar, it can be controlled with Captain Jack’s Deadbug Brew, which contains Spinosad and is all-natural. Bug Blaster 2.4, which includes Bifenthrin, is highly effective.
