1st Gypsy moth treatment complete, 2nd planned for May 16 for Kosciusko and Porter counties
Start Date: 5/12/2017
Event Description:
Weather conditions were favorable today, and the first treatment to slow the spread of gypsy moth at eight sites in Fulton, Kosciusko, Marshall and Porter counties was completed by 9:45 a.m. ET.

The second treatment for four sites, three in Kosciusko County and one Porter County, is planned for Tuesday, May 16, weather permitting. If weather does not allow for treatment on Tuesday, it will be done on Wednesday or the next day that weather allows. Low wind speeds, which usually occur in early morning after sunrise, and no rain for six to 24 hours after treatment are the needed conditions.

During treatments, people may see a yellow airplane flying 75-125 feet above the treetops.

Using today’s treatment timeline as a guide, the second treatment should start between 5:30-6 a.m. ET and should end between 8-8:30 a.m. ET. As with the first treatments, the times may change depending on the weather.

Delays will be announced on the Gypsy Moth Twitter site, Postponements will be announced on there and by news release.

Detailed maps of the treatment sites are at The sites scheduled for treatment on Tuesday include Harrison Township, Pierceton West, Rosella and Valparaiso South.

The airplanes distribute a spray containing the bacteria Bacillus thuringiensis var. kurstaki, often referred to as Btk, into the treetops of infested areas where gypsy moth caterpillars feed. Btk occurs naturally in soil. Btk kills gypsy moth caterpillars as they feed on tree leaves by disrupting their digestive systems.

Btk has been used for decades by organic gardeners and has an excellent safety record with people and animals. People who live or work near the treatment areas might choose to take common-sense precautions, including staying inside when the planes are flying, and for about 30 minutes after treatments are complete. This gives the material time to settle out of the air and adhere to treetops.

Two treatments to slow the spread of gypsy moth are planned for mid- to late June. One site is situated where Fulton, Kosciusko, Miami and Wabash Counties meet, and the other site is in Porter County.
