Professional Inchworm Management

Inchworms, also known as cankerworms or spanworms, are more of a nuisance with the threads that they dangle by when walking through. They can make some holes in foliage but usually don't cause enough damage to harm the tree. Our targeted treatment programs help manage these pests when they become problematic.

Inchworm control for spring tree protection

Commonly Affected Trees

Oak trees
Elm and ash

Treatment Timing

Early intervention is critical for inchworm control. We apply treatments in early to mid-spring when caterpillars are young and most vulnerable, before significant damage occurs. Timing based on degree days and tree phenology ensures maximum effectiveness.

Protect Your Trees

Severe defoliation weakens trees and makes them susceptible to other pests and diseases. Our preventive treatment programs keep inchworm populations under control, preserving the health and beauty of your landscape.
