Spongy moths have triggered quarantine notices in many counties in the state. Those in lighter shading on the right side of the map have had a quarantine on moving regulated articles such as trees, logs, pulpwood, bark and bark products and many others, since 2017. The most recent quarantine was Douglas County in northwestern Wisconsin. This quarantine includes Christmas trees and firewood. It is also important, when moving or closing up the cabin and taking outdoor items home, to closely inspect all outdoor items to ensure there are no spongy moth egg masses hitching a ride on them as well.

Time to be on the look out for spongy moth eggs
Spongy moths, formerly known as Gypsy moths, are known to defoliate hundreds of kinds of trees, shrubs and plants, but are a special concern for oak, aspen, birch and willow in Wisconsin. At this time of the year, spongy moth egg sacks can be found attached to nearly anything that is outdoors, whether that be trees or even garden equipment or outdoor furniture.
