Crystal Lake will use pesticides to eliminate gypsy moth problem

The City of Crystal Lake, in cooperation with McHenry County, will again implement gypsy moth control efforts throughout the city.

Gypsy moth infested sites will be treated by helicopter with an application of Btk, a naturally occurring bacteria used by gardeners as an environmentally friendly alternative to chemical pesticides.

The first aerial treatment is scheduled for Wednesday or Thursday. A follow-up application will occur during the week of June 2. Actual application dates and times are subject to weather conditions.

The gypsy moth is a non-native, leaf-eating insect that feasts on plants and shrubs. Gypsy moths are among the most destructive forest and landscape pests in the United States. Oak trees are the most vulnerable to gypsy moth devastation, but the caterpillars will feed on up to 500 other types of trees and shrubs if oak leaves are scarce.
