Officials will set more than 14,000 gypsy moth traps across Minnesota this spring as part of the state's annual monitoring program for the destructive tree pest. Gypsy moth caterpillars eat the leaves of many trees and shrubs.
Agricultural officials are preparing their largest air war ever to protect the forests of northeastern Minnesota and northwestern Wisconsin against gypsy moths.
Even though it's the middle of a frigid Minnesota winter, officials are already planning to eradicate three gypsy moth infestations in the Twin Cities area this spring.
