The DCNR Bureau of Forestry has discontinued what was known as the Cooperative Gypsy Moth Suppression Program.
According to the 2021 DCNR web information, landowners are responsible for their own properties.

Private property was dropped from DCNR’s suppression program due to lack of funding; therefore, it costs homeowners far less to hire an applicator on their own than to participate in state spraying, which includes operation/program/personnel costs.
A list of applicators is available for landowners on the following webpage:
