Forest tent caterpillar populations have been rising in some northern and west-central Minnesota counties since 2007, and that trend is expected to intensify, the Minnesota Department of Natural Resources (DNR) said.
It seems that those of us with gardens or flowers to keep luscious and healthy throughout the growing season are always dealing with some sort of garden pest. Why is it that the tastiest snack has to be the most gorgeous or best producing plant in the yard?

The Minnesota Department of Natural Resources (DNR) will soon be flying an aerial detection survey across the state to pinpoint where defoliation from forest tent caterpillars has occurred this spring and to what severity.
What are these little buggers, and how can we control them?
Here are the facts:
These caterpillars live throughout the U.S. and nosh on hardwood trees like balsam poplar, basswood, oaks, ashes, birches, alder, fruit trees, and their favorite, quaking aspen. When they are done munching on trees, they often move to other vegetation, including vegetables, small fruits and nursery crops. They rarely eat red maples or conifers, such as pine and spruce.
