Why is there a Suppression Spray Program?
The goal of the Suppression Program is to protect valuable trees from mortality by controlling gypsy moth population outbreaks in areas where the gypsy moth is established.

The Suppression Program assists communities and landowners in the management of gypsy moth by providing the expertise and equipment for aerial sprays. Treatments under this program are paid for by the Roscommon County millage.

The program uses Organic Certified Foray48B® a naturally occurring soil bacteria, Bacillus thruingiensis var. kurstaki or B.t.k., applied by aerial spray.
