Pest Control Community

I have become aware of the fact that Gypsy Moth treatments are to begin in Montgomery County as early as May 1st this year. Gypsy moths, not to be mistaken for the Eastern Tent Caterpillar, are part of the Maryland Department of Agriculture’s pest “suppression program” - a unique collaborative between state, local, and landowner jurisdiction to control potential widespread defoliation in our region.

Although the Eastern Tent Caterpillar is commonly mistaken for the Gypsy Moth Caterpillar, as both are equally prolific in Maryland, the latter is vastly more destructive to our native trees. Per the Maryland Department of Agriculture, in some parts of the country, “large outbreaks have affected hundreds of thousands of acres statewide.”

The effects of defoliation of trees in healthy hardwoods can sometimes be reversed, but in many cases, the trees are weakened and fall prey to other forest pests or even disease.

Many enviromental factors play an important role in controlling Gypsy Moth populations and certainly common predators such as wasps and several bird species also contribute as natural enemies. It is important to understand that since the early 1970’s, in Maryland alone, our State Department of Agriculture has conducted many worthwhile efforts to control Gypsy Moth propagation.

The State Dept., USDA Forest Service, local jurisdiction, and local homeowners have partnered together to form the Gypsy Moth Cooperative Suppression Program.
