Non-Chemical Management
- Pick out and destroy the foamy-looking, grayish, 1/2" egg cases during the fall and winter. These may be found in bands around twigs or in flattened masses on trunks.
- Several natural parasites and predators help control tent caterpillar populations. Avoid use of broad-spectrum insecticides which kill beneficial insects.
- Strip or prune out and destroy nests and caterpillars as soon as noticed. This is best done in early morning or evening, when caterpillars are gathered in the nests.
