Armyworms: These caterpillars move and feed in large groups, stripping turf and vegetation around facilities in a matter of days. Heavy outbreaks leave brown, bare patches and weaken grounds, creating poor site conditions and swarms of adult moths later in the season.

Webworms: Known for spinning large silk webs in trees and shrubs, webworms defoliate branches and create unsightly nests. When webs break open, the caterpillars drop onto walkways, equipment, and outdoor work areas, disrupting employees and causing sanitation concerns.

White-Marked Tussock Moth Caterpillars: Easily identified by their red spots, white tufts, and black pencil-like hairs, these caterpillars cause painful skin irritation when touched. They commonly appear on trees near industrial units and can fall onto people or property, creating both safety issues and workflow disruptions.
