Do you have Bagworms in your Columbus, Ohio, yard?

Pupa of the Bagworm (Oiketicus kirbyi) attached to a wire fence.Bagworms are caterpillars that live on host plants in bags made from their silk. The worms use foliage, bark and other debris to camouflage the bags, which range in size from 1.5 to 2.5 inches long.

There may be 300 to 1,000 eggs laid each year, in each bag. The eggs hatch in late May or early June and the newly-born larvae crawl out the bottom of their bag and spin down a strand of silk. Usually the wind catches these wandering larvae and gusts them up to another nearby tree or bush. Once the larvae choose a host tree that they like, they start making a bag and settle in.

Once the bagworm larvae are nestled in their host tree they may eat the plant buds, needles or leaves, causing branch dieback and dead areas. Not only is this unsightly, but if the worms eat too much of the foliage the entire tree may die.

Plants that Bagworms Prefer Include:

  • Arborvitae
  • Red Cedar
  • Pine
  • Spruce
  • Cypress
  • Willow
  • Maple
  • Elm
  • Poplar
  • Oak

Bagworms often go unnoticed until they are already mature. If you have a bagworm infestation in your yard, here are two ways to handle it:

  1. Pick Bagworms by Hand: You can go around your yard and pick the bags off of your plants and destroy them. The bag is suspended from extra silk wrapped around a branch. The silk is very durable and can damage the branch as the tree grows so make sure to remove the silk band when you remove the bags.
  2. Control Bagworms with Chemicals: Bagworms can be controlled with certain insecticide sprays. There are four stages in a bagworm’s life: egg, larva, pupa and adult. Depending what part of the life cycle they are in, pesticide applications can kill the larvae after the eggs have hatched.
