Evergreen Bagworms might sound harmless, but they can seriously damage your trees!
These pests are actually the larval stage of a moth, not worms. They threaten both deciduous and evergreen trees, causing severe damage if left unchecked.
Officially called Thyridopteryx ephemeraeformis, these bagworms get their name from the protective “bag” they build around themselves. They spin silk threads and attach twigs and leaves to their bodies, creating a growing casing that provides camouflage and shelter.
Bagworm Lifecycle: The female lays eggs in her bag, which sticks to the tree after she dies. Over winter, these eggs hatch into larvae in late spring or early summer. The larvae attach to trees, build their own bags, and gradually expand them as they grow. After about two weeks, they transform into moths, with males flying off to mate.
How to Manage Bagworms:
Remove them by hand: Pick off the bags manually.
Prune branches: Cut away affected parts of the tree.
Encourage predators: Attract birds and parasitic wasps.
Use insecticides: Apply bagworm-specific treatments.
Prevention Tips:
Inspect regularly: Check trees in spring and summer.
Maintain tree health: Prune and nourish your trees.
Remove infestations: Get rid of bagworms as soon as you spot them.
Space trees properly: Reduce risk by spacing trees adequately.
Monitor nearby plants: Bagworms can spread between trees.
Even though Evergreen Bagworms might not look menacing, they can do a lot of harm. Keep a close eye on your trees to keep them healthy!
