The varmints are fattening themselves for winter while destroying the crops with bite marks.
Robert Randall, who has a 60-acre orchard in Standish, Maine, said he's never seen anything like it.
"They're eating the pumpkins. They're eating the apples. They're raising some hell this year. It's the worst I've ever seen," he said.
Evidence of the squirrel population explosion is plain to see along New England's highways, where the critters are becoming roadkill.
Last year, there was a bumper crop of acorns and other food that contributed to a larger-than-normal squirrel population this summer across the region, said Rob Calvert, wildlife biologist from the New Hampshire Fish and Game Department.
This summer, there's not as much food, so the squirrels are looking for nutrition wherever they can find it, including farms, Calvert said.
New England is home to both red and gray squirrels. Known for their bushy tails, the rodents are a common sight in city parks and backyards, and people enjoy watching their frenetic movements.
They eat everything from beechnuts and acorns to berries and seeds.
And, apparently, apples, peaches, high-bush blueberries, pumpkins and gourds. In New Hampshire, squirrels have been raiding corn fields, dragging away ears.
"It is crazy. You see squirrel tails everywhere," said Greg Sweetser, who has a boutique apple orchard in Cumberland Center, Maine. In the past, he said, squirrels have sometimes nibbled on apples that had fallen to the ground. But this season they're skittering into the trees, scurrying to and fro, and making their mark.
Oftentimes, the squirrels will take a single bite, then move on.
But a single bite is all it takes to ruin fruit.
In Vermont, where the harvest is just beginning in earnest, farmers are keeping a watchful eye because rodent damage has been a growing problem for its apple producers, said Eric Boire, the president of the Vermont Tree Fruit Growers Association.
The good news for farmers is that boom years for both acorns and squirrels are uncommon. Thus, it's likely that populations will return to normal soon.
The fact that squirrels are hustling to find food, and getting run over in prodigious numbers on highways, suggests the culling already has begun, Calvert said.
As hungry as the squirrels are, it's unlikely that they'll inflict massive economic damage.
"Every year in farming, there's something that we're dealing with," said Margie Hansel, an owner of Hansel's orchard in North Yarmouth, Maine. "It is what it is. It's part of farming. You expect to have something like this happen every once in a while."
