Spongy Moth Spraying Scheduled for Thursday, May 19, 2022

St. Clair County is planning to spray insecticide treatments aimed at suppressing Spongy Moths starting tomorrow, Thursday, May 19, 2002 beginning early in the morning.

Weather conditions are predicted to be optimal for aerial spraying, and A1’s Aerial Spraying LLC will be releasing insecticide on 5,300 acres around St. Clair County. If the weather conditions change, spraying will be rescheduled.

A1’s Aerial Spraying plans to release Btk (Bacillus thuringiensis var. kurstaki) via airplanes on the tree canopies in areas most inhabited by Spongy Moth caterpillars. The insecticide is water-based and approved for use in certified organic food production.
