Bagworms look like small pine cones that hang from the branches of trees and shrubs. Many people do not realize they have them until damage has already begun.
The best way to get rid of bagworm cocoons is to handpick them off the infected tree. Place them in a trash can versus tossing them on the ground as they will climb back up into the plant.
Insecticides can only be used in the larval stage, which usually occurs at the end of June or around the time 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 but can also live on other trees and shrubs, including deciduous.
Heavy infestations over several years, especially when coupled with other stresses, can lead to plant death.
