Gypsy Moth Caterpillar Infestation

Dear residents,

My office has received many calls about the infestation of gypsy moth caterpillars to parts of the Town of Glenville. Gypsy moths are an invasive species that feed on tree leaves and typically follow a seven- to 10-year cycle. When populations rise rapidly, they are usually followed by a crash from a host-specific virus or fungus. These rainy days we are currently experiencing may actually help create with this natural control.

Unfortunately, gypsy moths are here to stay and the best we can do is to make sure they don’t spread uncontrollably and cause major destruction to our trees. At this stage in the caterpillars lifecycle, the best way to eliminate them is to physically pick them off the trees and drown them. You must wear proper protective equipment when handling the caterpillars which may cause rashes in some individuals. Please keep in mind that healthy trees can withstand an attack and even endure a gypsy moth infestation, so the best prevention is taking appropriate care of your trees with proper watering, fertilization, and pruning.

We have included more information on the Town website, under parks, protecting our trees, gypsy moth fact sheet. (Link here.)

I have invited Scott Moxham, the DEC forester for our region, to join our Town Board meeting to give a short presentation about gypsy moths and potential interventions on Wednesday, June 9th  at 7 p.m. Please attend to learn more.

All the best, 

Chris Koetzle 

Town Supervisor
