How to get rid of bagworms

What are Bagworms?

Bagworms are a type of moth that live in bags made from silk and bits of leaves. A bagworm larva grows inside this bag by feeding on leave, and it attaches its bag to tree branches or other surfaces using silken threads. The bags are brown or green in color and can reach up to 10 centimeters in length. Bagworms themselves are small, with adults measuring only a few millimeters in length.

What are bagworms?

Bagworms are a type of moth that live in bags made from silk and bits of leaves. A larva grows inside this bag by feeding on leaves, and it attaches its bag to tree branches or other surfaces using silken threads. The bags are brown or green in color and can reach up to 10 centimeters in length. Bagworms themselves are small, with adults measuring only a few millimeters in length. When fully grown, the caterpillar bagworm will pupate inside the bag, emerging as an adult bagworm moth a few weeks later. Bagworms are found all over the world, and while they can be a nuisance to gardens and crops, they generally pose no threat to humans or animals.

The lifecycle of a bagworm

Bagworms go through four stages in their lifecycle: egg, larva, pupa and adult. They lay their eggs inside a bag, which hatch after about two weeks. After hatching from the eggs, the larvae immediately begin to build their own bags. The larvae feed on leaves as they grow, adding bits of plant material to their bag as they go. The caterpillar will pupate inside the bags. The pupa stage lasts for a few weeks, after which the adult moth emerges.

The adult moth is short-lived, surviving for just a few days to mate and lay eggs. Females lay as many as 1,000 eggs during their brief lifetime and can produce several generations per year, with each generation causing increasing damage to plants.

What damage do bagworms cause?

bagworm defoliationAccording to the USA National Phenology Network, bagworms defoliate up to 50 different species of evergreen and deciduous trees and shrubs. Because bagworms feed on leaves, this can cause significant damage to trees, shrubs and other plants. Bagworms are particularly fond of evergreens and can strip a tree of its foliage in just a few days. They can also infest crops such as corn and sorghum, and in large numbers, they can defoliate an entire field.
