How To Get Rid of Bagworms in Trees in Clovis, CA

The summer is a wonderful time for outside activities and events for humans, but it’s also prime time for a bagworm infestation. This season is when many homeowners wonder how to get rid of bagworms in trees.

Bagworms can be some of the most irritating pests for the gorgeous yard, trees, and landscape you’ve worked so hard to build. Cut Rite Tree Service is here to provide licensed tree service in Clovis, CA, and protect your beautiful outdoor space from harm.

What Is a Bagworm?

A bagworm is the larvae of a bagworm moth. They get their name because they create silky sacks that hang from evergreen trees. Those sacks can hold 1,000 eggs, and the eggs hatch around early June. Those larvae then eat your tree branches, which can destroy them.

Bagworm Problems and What You Can Do About Them

Bagworms gravitate toward coniferous trees like spruce and juniper. However, they’ll attack more than 100 tree species. Bagworm larvae eat tree buds, needles, and other plant material. In the worst infestations, bagworms can eat 80% of the tree or more. This completely kills the tree.

What Bagworms Eat

Bagworms make themselves at home in more than 100 tree species. They prefer coniferous (evergreen) trees including:

  • Spruce
  • Juniper
  • Red Cedar
  • Arborvitae
  • Pine

Bagworms also like other trees, including:

  • Poplar
  • Maple
  • Boxelder
  • Willow
  • Sycamore
  • Honey Locust
  • Oak
  • Linden

How To Get Rid of Bagworms Before They Hatch

How to get rid of bagworms in trees is simple — you just cut the bags off the tree branches and throw them away. You need a pair of sheers, a bucket of water and dish soap, and some plastic bags. The steps are:

  1. Lift the branch.
  2. Cut the bagworm egg sack off.
  3. Drop the bag into the bucket of soapy water.
  4. Put the egg sack into a sealed plastic bag.
  5. Throw the bag away.

Then you repeat this process every autumn, winter, and spring to halt the bagworm population before it starts.

How To Get Rid of Bagworms After They Hatch

If the bagworms have already hatched, spray them with insecticide. The best time to spray is when they’re actively feeding. This is usually late spring to early summer.

The caterpillars prepare for adulthood in the late summer and eat less. That means they won’t eat the insecticide.

If they’ve already stopped eating, wait until next season to spray.

Natural Ways To Get Rid of Bagworms

Some people don’t want to spray insecticide on their trees. You can use sprays with the active ingredient Bacillus thuringiensis var. Kurstaki.

It’s a bacteria found in soil that makes the bagworms stop eating. Without eating, they’ll die in a few days.

You can also attract natural bagworm predators by putting a birdfeeder in your yard. The birds eat the bagworm caterpillars.
