Wisconsin Sets 6,700 Spongy Moth Traps Across 36 Counties This Summer

State Agriculture Department Launches Summer Monitoring Program

The Wisconsin Department of Agriculture, Trade and Consumer Protection is deploying approximately 6,700 traps throughout the state. The initiative targets spongy moth detection and population monitoring. Officials will place these specialized devices in 36 counties across western and central Wisconsin through early July. Most traps will appear along public roadside rights-of-way.

Some traps may require placement on private property. This happens when evidence suggests a new spongy moth population nearby. State officials are asking residents not to disturb the monitoring equipment. The traps serve a critical function in measuring pest populations. They also help identify any new infestations before they spread.

Spongy moths were previously known as “Gypsy moths.” The name change reflects updated terminology in pest management. These invasive insects pose significant threats to Wisconsin forests and urban trees. The monitoring program tracks their movement across the state.

New Populations Emerge in Western Wisconsin

Outlier populations continue developing despite overall decreases. Spongy moth numbers dropped drastically across the state last season. However, new populations are appearing in western regions. Amanda Miller, DATCP spongy moth trapping coordinator, emphasized the importance of this year’s data collection.

“Even though spongy moth populations drastically decreased across the state again last season, there are still new outlier populations developing in western Wisconsin,” said Miller. “Data collected this season will be crucial in the program’s effort to pinpoint these new populations and limit their spread before infestations become large enough to cause damage to trees.”

The traps use a sophisticated attraction method. Small green boxes are stapled to or hung on trees. Each trap emits the scent of flightless female spongy moths. This lure attracts and catches adult male spongy moths. The scent remains undetectable to other insects, animals and humans.

How the Monitoring System Works

Trapping staff will monitor select locations throughout mid-summer. All traps will be removed between late August and September’s end. Staff members wear high-visibility vests and carry proper identification. Each trap displays a phone number for public inquiries. A QR code allows residents to scan for questions or report issues.

Property owners can request trap removal through these contact methods. They can also report any damage to monitoring equipment. The labeling system ensures transparency and public cooperation. State officials rely on community support for program success.

Past infestations have affected communities throughout Wisconsin. Janesville experienced significant problems with spongy moths previously. Local parks saw damage from the invasive species. City operations officials partnered with state resources to address the issue.

Natural Predation Strategies Support Monitoring Efforts

Local governments have implemented native grass programs in affected areas. These initiatives aim to bolster bird and mouse populations. The strategy relies on natural predation to control spongy moth numbers. Birds and small mammals feed on various life stages of the pest. This ecological approach complements traditional monitoring methods.

The combination of monitoring and natural controls offers comprehensive pest management. State officials continue refining their approach based on annual data. Early detection remains crucial for preventing widespread damage. The trap network provides essential information for targeted interventions.

Free Fun Weekend Offers Recreation Opportunities

The Wisconsin Department of Natural Resources announces its 14th annual Free Fun Weekend. The event takes place June 6-7. State park admission fees will be waived for all visitors. Fishing licenses and trail passes are also free during the weekend.

Wisconsin offers extensive outdoor recreation resources. The state maintains 50 state parks and 15 state forests. Visitors can explore 44 state trails. The state also features 84,000 miles of rivers and streams. Roughly 15,000 inland lakes provide additional recreation options.

First-Time Visitors Welcome at State Parks

Steve Schmelzer serves as DNR bureau director of parks and recreation management. He encourages new visitors to explore state properties during the free weekend.

“If you’ve never checked out a Wisconsin state park before, Free Fun Weekend is the perfect opportunity to come visit for the first time,” said Schmelzer.

Families can enjoy beach activities, picnics and hiking opportunities. The state park system offers diverse recreation for all ages and interests. Most state parks and trails will operate from 6 a.m. to 11 p.m. during the event. Select properties will feature new merchandise, including decorative stickers designed by DNR staff.

Free Fishing Weekend Introduces Anglers to Sport

The DNR promotes fishing opportunities during Free Fun Weekend. Residents can try fishing before purchasing annual licenses. Justine Hasz, DNR bureau director of fisheries management, highlighted the weekend’s benefits. The event provides an ideal introduction for beginning anglers.

Equipment availability extends access to the sport. The DNR maintains tackle loaner sites across the state. The Wisconsin Fishing Finder helps locate fishing spots. Free fishing clinics will operate at state and municipal properties. These instructional sessions target beginning anglers specifically.

Both residents and nonresidents can fish without licenses during the weekend. All linear and rail trails will open to the public. Trail passes are not required for any users. ATV, UTV and OHM operators still need proper registration. However, trail passes are waived for the weekend.

Planning Your Free Fun Weekend Visit

Vehicle admission passes are not required at state parks. Visitors should check the DNR Events calendar for specific activities. The Wisconsin State Parks webpage lists additional property information. Advanced planning ensures the best experience during the busy weekend.

The event coincides with National Trails Day celebrations. Trail enthusiasts can explore horseback riding and ATV routes. The combination of free access and seasonal weather creates ideal outdoor conditions. State officials anticipate strong participation across all recreation categories.

The dual initiatives of pest monitoring and recreation access reflect Wisconsin‘s environmental stewardship. Spongy moth trapping protects forest resources for future generations. Free Fun Weekend introduces residents to their public lands. Both programs support sustainable use of natural resources.
