Insect Overview
The Brown Tail Moth is a destructive insect that primarily affects hardwood trees, including oaks and apples. The caterpillars of this moth cause severe defoliation and can weaken trees significantly. In addition to defoliation, their toxic hairs can cause skin irritation in humans and animals.
Brown Tail Moths thrive in early spring when they hatch and begin feeding on tree foliage. The damage caused by these caterpillars can stunt tree growth, increase susceptibility to other diseases, and reduce overall tree health.
Early detection and control are essential to minimize damage. Regular monitoring of trees during the spring and early summer months is crucial to identifying infestations before they become widespread.
Symptoms
- Defoliation of tree foliage, particularly in the spring and summer months.
- Presence of webbing on tree branches and leaves.
- Skin irritation caused by contact with the toxic hairs of the caterpillar.
Recommended Treatment
Apply Vivid-II as a treatment to control Brown Tail Moth infestations. Follow the application instructions for proper dosage based on tree size and pest severity. The treatment should be applied during the early stages of infestation, typically in late spring when caterpillars are actively feeding.
Treated Species
Many tree species may be affected by Brown Tail Moth Treatment Guide. However, Vivid II is only approved for use on the following trees per the EPA product label.
- Ornamental Trees (including forest, ornamental, non-crop-bearing trees, and woody shrubs)
