Spongy (Gypsy) Moth Resources

The spongy moth (formerly known as the gypsy moth) has been a destructive forest and tree pest in Pennsylvania since 1932. Infestations are cyclic and regional, so different portions of the state may be affected during each cycle.

Throughout the late Spring of 2022, College Township has been made aware of a growing spongy moth infestation in certain portions of the township. No spraying program was budgeted for 2022, but consideration for a program will be given as part of the 2023 budget process. 

The following links are provided to give residents additional information on the spongy moth, as well as, resources to aid in combatting the latest infestation:
