A few months ago I posted an article on tent caterpillars. You have probably noticed that we are now experiencing an “invasion” of fall webworms. This pest is different from the tent caterpillar in that they build their nests out on the tips of branches in the fall. These nests will continue to expand to include more and more of the tree as the season advances. Because this pest is active so late in the season, there is little threat to the health of the tree. They can also be easily controlled in the landscape simply by breaking open the nest and destroying the caterpillars inside. This also allows for predation by birds and wasps.
