Gypsy moth quarantine in Minneapolis neighborhood

Gypsy moths can eat over 300 species of trees. They only surfaced in Minnesota about a decade ago.

MINNEAPOLIS -A Minneapolis neighborhood is under quarantine after a Gypsy Moth infestation. The same voracious moths were eradicated in three Georgia counties. 

The Minneapolis homeowner, who wanted to remain anonymous, says he first found the bugs three weeks ago.

"I saw this dark clump of something on my tree and when I took a closer look I discovered it was a bunch of caterpillars."

Agriculture officials were notified a short time later. Experts found numerous trees oozing with caterpillars.

A quarantine was soon issued to prevent the invasive bugs from spreading to other parts of the city.

"We are restricting the movement of woody debris, like branches, yard clippings and tree trimmings," plant pest regulatory specialist Marissa Streifel says.

The quarantine also prevents homeowners from moving other outdoor items off their property such as boats, trailers, and sheds. 

"If a homeowner needs to move those items they should check them thoroughly for egg sacks and caterpillars that might be on them," Streifel says.

Streifel says the quarantine will be in effect until next spring when the Department of Agriculture can spray pesticide in the neighborhood.

"We have to wait until next spring when the caterpillars are hatching and are in a certain stage," Streifel says. 

"The pesticide coats the leaves and when the caterpillars eat the leaves the bacteria gets in their gut and makes it so they can't absorb nutrients. They basically end up starving."

The pesticide is not supposed to be harmful to humans.

Ag experts say the caterpillars can wreak havoc on trees by eating all their leaves and exposing them to other diseases and infections.

The moths originally came from Europe and Asia and have been in the United States since the 1800s. However, the first recorded sighting in Minnesota wasn't until the early 2000s.

The Georgia Forestry Commission reports Gypsy Moth had been spotted in White, Fanin, and Rockdale counties. Those outbreaks were eradicated by state and federal forestry officials. Those moths were believed to come from individuals moving cargo with egg masses attached to it from infested areas. The Commission says it will be many years before the natural spread brings Gypsy Moths to Georgia. It's one of the reason aggressive quarantine measures are in place.
