DNR Announces Aerial Spraying for Spongy Moth Caterpillars in Devil’s Lake State Park

Advisory for Property Taxpayers Mailing Tax Payments: USPS policy change on postmarks may affect tax payments. In August 2025, the U.S. Postal Service changed when postmarks are affixed to incoming mail. Instead of being affixed when the item is first received by the post office, postmarks are now stamped at regional sorting centers. Please be aware that this change may affect when your envelope containing your tax payment is postmarked. Property tax payments received by mail are considerd timely based off of the USPS postmark. To avoid a tax payment becoming delinquent due to the postmark change, consider the following options: If you plan to pay your property taxes by mail, mail your payment earlier, or, use a service such as certified mail. Make a payment in-person during the hours of M-Th 9am-3pm, and Fridays 11am-2pm through January 30th, except for holidays.

DNR Announces Aerial Spraying for Spongy Moth Caterpillars in Devil’s Lake State Park

The Wisconsin Department of Natural Resources (DNR) today announces aerial spraying operations will soon take place over four DNR properties to combat spongy moth caterpillars, formerly known as gypsy moth.

Spongy moth caterpillars strip trees of their leaves, potentially killing high-value trees. Spongy moth outbreaks occur every five to 10 years, and this year’s high populations threaten tree defoliation in high-use areas of some state properties.

The aerial spraying will take place in late May to early June, with the exact date and times depending on weather conditions and caterpillar development. The DNR plans to avoid spraying during the extended Memorial Day weekend if spraying has not taken place before then.
