DNR Says Expect Lots of Spongy Moth Caterpillars

(Raymond Neupert, WRN) Expect to see more spongy moth caterpillars this year.

The Department of Natural Resources says that weather conditions this spring were both favorable for the moths and unfavorable for the DNR's preferred pesticide, a fungus that specifically targets the moths. That could mean a population explosion over the next two years.

Forestry experts say people should be aware that many trees and shrubs could be stripped of leaves this year, and that people shouldn't cut down bare trees because the leaves can grow back. Lumber production may also be down because of the stress on trees.
