Lisle testified against that decision on April 10, 2025, in the House Committee on Environment and Energy, citing the financial and ecological costs of failed removal operations.
During the event, Lisle instead advocated for further implementation of the beaver deceiver, a device he designed to deal with beavers non-lethally. Lisle founded Beaver Deceivers International in 2001 and has implemented the devices across North America and parts of Europe.
“We spent years just building something, ripping it out, rebuilding it and the stakes were too high to ever give up,” Lisle said.
Each device is tailored to the physical characteristics of each dam site, and Lisle demonstrated their basic structure during his presentation.
A long pipe runs near the surface of the water and is covered with a square-shaped, fenced-in filter. The filter muffles the water flow as it runs through the pipe, subduing the sound that hinders beavers from continuing to build, Lisle said.
The devices allow water to keep flowing while the beavers are tricked into believing they’ve completed a job well done, while the beaver deceiver regulates water levels and damming behavior in a way that preserves the beavers’ habitats.
The Fish and Wildlife Department has installed more than 300 beaver baffles, devices similar to the beaver deceivers, across 3,000 acres of wetland habitat to protect beavers and minimize their damage, too.
Good for you Skip. There are enough beaver-savvy Vermonters to make this work
Bev Soychak, co-founder of the Vermont Beaver Association, encouraged community members to consider flow devices similar to the beaver deceiver rather than trapping, emphasizing that it’s possible to coexist with their wood-chucking neighbors.
“We’re here to encourage beavers to be able to thrive in their environments because of their benefits,” Soychak said. “Instead of killing that beaver, call us and let us do a beaver deceiver, and then you can build around it.”
I’d say with all of you hard at work on the problem your beavers have a fighting chance. If you can’t compromise in Vermont, where can you hope for peace?
