Browntail Moth

Browntail moth caterpillar

This spring, the Town will conduct a spraying program of street trees in the public right of way to combat the infestation of Browntail moths. Spraying will take place from 4:00 am until 7:00 am.

Spray Schedule update: The Town's spraying program was completed on Friday, May 25.

The Town’s contractor, Whitney Tree Service, will spray a chemical called Conserve SC from the roadway with a truck mounted mistblower to treat infested trees on the public roads marked in yellow on the map linked in the list below. Only those trees located in the public right of way that have nests will be sprayed as part of this project. Property owners with nests on other parts of their property will need to hire a qualified contractor.

For more information, contact Melissa at Town Hall at or 699-5335.
