“They rarely cause any kind of damage at all,” she said. “Unless you have a tree, and you’re hoping for apples, and that tree is being consumed by the caterpillars, you don’t have anything to worry about.”
I began noticing caterpillar tents in the branches a couple of weeks ago in northwest Minnesota when returning from Lake of the Woods after the Fishing Opener.
Mistakenly thinking they were forest tent caterpillars, I feared the worst. There hasn’t been a severe forest tent caterpillar outbreak in northwest Minnesota since 2001, so I’m glad I was mistaken.
In 2001, forest tent caterpillars defoliated more than 7.5 million acres of hardwood trees and shrubs in Minnesota, DNR statistics show.
