The state Department of Agriculture, Trade and Consumer Protection (DATCP) works with the U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS) to enforce a spongy moth quarantine in Wisconsin, with the goal of limiting the spread of the spongy moth to new, uninfested areas.

The quarantine now covers 53 of Wisconsin’s 72 counties. The quarantine regulates woody nursery stock, Christmas trees, firewood, logs and outdoor household items. Quarantine regulations apply to businesses and private citizens.

As of early July, we have seen a mix of live and dead caterpillars and tree defoliation that is typical of a late-stage spongy moth outbreak. Reports of defoliation have been received as far north as Florence County.

Recent aerial surveys in southern Wisconsin spotted defoliation in the same general areas as in 2023, but the defoliation has generally been less intense this year. Information for northern Wisconsin has yet to be made available. Refoliating oaks, growing a second set of pale-looking leaves, were seen in Walworth County in early July.

Eastern white pines (Pinus strobus) can be beautiful trees in urban and forested areas (they can tower above the rest of the forest’s trees), but they can also attract a deadly disease.

White pine blister rust (Cronartium ribicola), also known as WPBR, is a fungus that can attack branches and the main stem of white pine, causing cankers that continue to grow each year and creating dead spots that can girdle branches or the main stem. Damage from a girdling canker may take years to become severe enough to cause tree decline and mortality. That means you may be able to help your trees and prevent mortality.
