Gypsy Moth

Village History With Moth

The Village completed aerial spraying in 2008 to curb the gypsy moth population. We will assess the results to determine what will be done in 2009. Read General information regarding the Gypsy Moth.

Listed are some steps a homeowner can take to prevent infestation (These have not been tested by the Village nor are they sworn to be 100% effective).
  • Keep trees watered and healthy
  • Wrap burlap around the trunk of the tree to catch the larvae as they climb and then dispose of the caterpillars in a bucket of soapy water.
  • Have an arborist scrape the egg masses off of the trunks.
  • Companies such as Bayer Advanced and Safer Brand market traps to catch the moths as they fly.


Gypsy moth infestations are a nuisance to residents, and uncontrolled populations can be detrimental to the health of trees as moth larva eat most leaves. According to Urban Forest Management, the Village's professional forestry advisors, oaks usually suffer more than other tree species from an attack. Deciduous trees in good condition prior to infestation can withstand one or two consecutive years of defoliation before decline, while evergreens die after one complete defoliation.

Hendrickson Flying Service (HFS)

This year, the Village contracted with Hendrickson Flying Service (HFS) of Rochelle, Illinois to conduct the spraying. HFS provides gypsy moth spraying services to several municipalities in Lake County, as well as the State of Illinois. Because the Illinois Department of Agriculture has suspended gypsy moth control efforts in Lake County, it is up to individual municipalities to address the problem.

A biological insecticide by the name of Foray 48F was used to treat the gypsy moths.
