SPRINGFIELD, Ill. The Illinois Department of Agriculture is scheduled to complete its 2004 Gypsy Moth treatment program this month with applications of pheromone flakes to moth-infested sites in six northern Illinois counties.

Weather permitting, the final applications of the year will be made the week of June 20 in Carroll, Cook, DuPage, Kane, Will and Winnebago counties. Five, yellow, single-engine, fixed-wing airplanes will apply the flakes, a sexual attractant that disrupts the mating of the moth, to trees in ten treatment areas.

The treatment areas consist of 18,540 acres of land and include four sites in DuPage County, two in Cook County and one each in Will, Kane, Carroll and Winnebago counties. The DuPage County sites will affect the communities of Bartlett, Wayne, Roselle, Bloomingdale, Medinah, Itasca, Warrenville and Naperville, as well as non-residential areas of Burr Ridge, Willow Springs and Lemont and parts of the DuPage County Forest Preserve.

In Cook County, affected areas include the cities of Westchester, LaGrange, LaGrange Park and Western Springs, as well as forest preserves adjacent to Palos Heights, Crestwood, Midlothian, Oak Forest and Orland Park.

South Naperville will be treated in Will County, and Batavia will receive an application of pheromone in Kane, along with portions of forest preserve. Other treatment sites include an area southeast of Mt. Carroll along Cyclone ridge, Telegraph, Daggert and Route 75 in Carroll County and a rural area near Meridian and Montague in Winnebago County.

The Gypsy Moth is a destructive, non-native pest that feasts on the foliage of trees and shrubs. Large populations are capable of stripping plants bare. Pheromone, the material being applied to control the moths, is non-toxic to humans and other mammals, birds, fish and most insects.

The applications currently are scheduled to begin Thursday, June 24, and will take one to two days to complete. However, the schedule is subject to change because of inclement weather or delays the aerial applicator may experience while finishing similar work in Ohio and Indiana.

Funding for the treatments comes from the Slow the Spread program, a state and federal effort to control the spread of the Gypsy Moth.
