Bagworms look like small pine cones that hang from the branches of trees and shrubs. Many people do not realize they have them until the damage has already begun.
The best way to get rid of bagworm cocoons is to handpick them off the infected tree and dispose of them in the garbage.

Insecticides can only be used in the larval stage, which usually occurs at the end of June or when Japanese Lilac Tree's are in bloom. Any other time and the insecticide may not work. We recommend using Captain Jack's Dead Bug Brew.

Bagworms prefer juniper, arborvitae, spruce, pine, and cedar and may live on other trees and shrubs, including deciduous. Heavy infestations over several years, especially when coupled with other stresses, can lead to plant death.
