Aerial treatments to slow the spread of the invasive gypsy moth are
scheduled to begin Thursday, May 17, at the Tiosa site in Fulton County.
Detailed maps of treatment sites can be found at gypsymoth.IN.gov.
The plane should arrive in Tiosa around 6:30 a.m., and the treatment
should take about an hour.
Treatments could be delayed if weather conditions become unfavorable. A
second treatment is scheduled for early next week.
