Has anyone tried these? Gimmick or effective? Thanks

Gimmick. You have no proof that you are actually killing the moles. And even if you did kill the moles, when neighboring moles move in your customer will start questioning your method. They can’t deny the proof of a dead mole in a trap. Save your money and time and get some traps and learn to be efficient with them.

I agree with parts of that. I do have a Burrow rx. Yes you can’t be sure you have killed them all. They seem to work best for me in winter-spring while soil is wet. Once dry our soil cracks and you get to many escapes areas. I do like to use on jobs that have lots of area, lots of activity and are a fair distance away. I do make extra trips to trap afterwards, but feel it does save some time and work.

I appreciate the response and honesty wws. My feeling is, if you have make extra trips to trap afterwards, you're not saving yourself time and work, you're doubling your work.

All depends, If I'm looking at 50 acres with lots of damage? Roll thru and gas the place up. come back and there are only a few left to trap It's a time saver. Our moles don't tunnel shallow like I see pictures of. They are mostly 6 inches to a foot underground. I'm pretty good at trapping but a big project does take multible trips.
