Gypsy moth spraying set for Monday over Vancouver

The second round of spraying for Asian gypsy moths is scheduled for Monday morning.

According to Washington Department of Agriculture spokesman Hector Castro, spraying over the Port of Vancouver and near some nearby residential areas is expected to begin at 5:45 a.m. Monday and be completed by 7 a.m.

Low-flying aircraft will spray the insecticide BTK to combat the highly destructive invasive moths. However, the work is entirely weather-dependent and could be rescheduled in the event of high winds or rain.

Officials planned three insecticide applications to combat the moth. The first was Sunday, April 17. The third and final application will be announced later, but no solid day is planned.

“We’re not going to make that call until we get through the second application,” said Bruce Pokarney, director of communications for the Oregon Department of Agriculture. Although Vancouver is under Washington’s jurisdiction, Oregon is handling the logistics for spraying Vancouver due to its proximity to spray sites in Portland.

The spray disperses bacteria, bacillus thuringiensis var. kurstaki. It has been used for decades in organic farming, and research has shown no health impact to humans, fish, pets or bees — only caterpillars. Still, officials recommend residents stay inside during and for 30 minutes after the spraying.
