Caterpillar Nests in Trees – What You Need to Know

Those Silky Webs Aren’t Harmless

If you’ve noticed silky, web-like nests in the crooks of your tree branches around Chester County, you’re not alone. These nests are made by caterpillars—typically fall webworms or eastern tent caterpillars—and while they may seem like a seasonal nuisance, they can actually do real damage to your trees if left unchecked. At Friendly Services, we’ve been helping neighbors identify and remove these nests the right way as part of our complete landscape services.

Why Caterpillar Nests Are a Problem

Caterpillar nests in trees often lead to defoliation—meaning the little critters eat the leaves faster than the tree can recover. While healthy, mature trees can usually survive a bout of feeding, repeated infestations over several seasons may weaken the tree and make it more vulnerable to disease or other pests. Young or ornamental trees are especially at risk in areas like West Chester, Kennett Square, and Malvern, where native plantings are common in residential landscapes.

How to Get Rid of Caterpillar Nests

The best time to remove caterpillar nests is early in the morning or late evening when the insects are gathered inside. You can prune and dispose of infested limbs (safely and properly, of course), or knock them out using a long stick and then bag them up. Avoid the urge to burn the nests—this can cause more harm than good and may violate local safety regulations here in Chester County. For taller trees or heavier infestations, our tree services team is equipped and trained to handle removal safely.

Prevention Is Just as Important

Preventing caterpillar nests begins with proper shrub and tree maintenance. Regular pruning reduces the dense growth that attracts webworms. Additionally, spraying trees with an insecticidal soap (when appropriate) can help control larvae without harming beneficial insects. And remember, keeping your landscape tidy—especially in early spring and late fall—can also help minimize overwintering eggs. If you need help with any of this, Friendly Services is right here in the neighborhood.
