Fall Armyworms Infestation Guide

Adult Armyworms are a common pest found in Bermuda grass, Ryegrass, St Augustine, and Zoysia grass. The name “Armyworms” is because they travel in groups and move through very fast. Armyworms are hard to spot in the beginning. They are small at first (about 1/8 inch). As a result, if you are not cautious, a large infestation can occur before you notice. The larvae feed for 2-3 weeks, and when fully grown, they are 1 to 2 inches long. Armyworms move quickly and reproduce in large numbers. The females can lay over 2,000 eggs. Armyworms typically lay their eggs are at the base of host plants. Adult Armyworms though, prefer to lay eggs on lush plants and grasses.

This is why early detection and treatment are essential to control the infestation of the fall armyworms. The most severe cases happen when armyworms attack during hot, dry weather. Therefore, it is crucial to watch for moths and damage when it is hot. In most cases, people find Armyworms, it is too late. However, you are not alone and we are here to help you!
