The first round of aerial treatments to slow the spread of gypsy moths in Porter, LaPorte, and Fulton counties and an eradication site in Wayne County was completed May 24th.
The first round of treatments involved aerial application of the bacteria referred to as Btk, into the treetops in areas infested with gypsy moth. Btk occurs naturally in soil and kills the caterpillars as they feed on leaves.
Further details about mating disruption treatments will be announced in June.
The gypsy moth is one of North America’s most devastating invasive forest pests. For more information, call 1-866-NO-EXOTIC (663-9684) or call the local county extension office at 1-888-EXT-INFO (1-888-398-4636).
