The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has initiated a comprehensive survey to track the presence of spongy moths across 36 counties in the state. This effort is particularly focused on identifying new populations in areas that were previously uninfested, especially in western Wisconsin.

Monitoring and Data Collection

Amanda Miller, the Spongy Moth Trapping Coordinator at DATCP, explained that the traps are essential for both monitoring known populations and detecting new ones. Despite a significant decrease in spongy moth numbers last season, new outlier populations have been identified, necessitating this survey to prevent potential damage to trees.

The traps used in this survey are small green boxes that emit a scent mimicking flightless female spongy moths, attracting and capturing adult males. While these traps primarily serve to gather data rather than directly reduce the moth population, the information collected is vital for future control strategies.

Survey Operations

DATCP staff will monitor selected traps during mid-summer, with all traps scheduled for removal from late August through September. These staff members are easily recognizable by their high-visibility vests and identification badges. Each trap is labeled with a contact number and QR code, allowing property owners to report any issues or request trap removal.

For those seeking more information on the spongy moth trapping program, resources are available on the DATCP Spongy Moth Traps and Egg Mass Surveys webpage. Additionally, inquiries can be directed to the hotline at (800) 642-6684 or via email at [email protected].
