In DE, we have “Zeckenrollen”. [1] They are filled with cotton material that mice will carry to their nest. And it’s treated with some tick killing substance.
Same thing, it is indeed permethrin on cotton balls in cardboard tubes. I've used them for several years. They help but they aren't a complete solution. Another thing I've tried is to attempt to control mice (remove wood piles and other places they nest) which also helps a little. There are a -lot- of mice in the woods if you live in a rural area. The owls in the area help too by eating the mice. A neighbors guinea hens used to roam my yard once in a while. Nothing has worked as well as Met52 so far. As far as I can tell there are no federal or state attempts to stop the spread, the problem has just been growing year after year.
Probably treated with permethrin. I've seen lots of guides about soaking cotton balls in permethrin and sticking them in cardboard tubes to place where mice might be nesting.
