First, I have never been very successful at trapping them. I have tried the scissor traps with little success. Just don't have the technique right. So I have been looking for another method.
Years ago I noticed that if I stuck a garden hose down the mound and washed water into the tunnel, overnight the mole would push the dirt back up. Sometimes they didn't do that, suggesting the mole wasn't working the area any more.
Yesterday, I stuck the hose down some holes in an area where the mounds had been refreshed since I had last mowed the lawn. Then I dropped in some dry ice, which if you remember your basic chemistry, evaporates into CO2, an odorless, tasteless, toxic gas which is also heavier than air. Put a little newspaper on top, then covered with dirt to seal it. The newspaper was to insure the CO2 could disperse into the tunnel freely without also being wasted up to the atmosphere.
So far, no sign of mole activity!
I have plenty of more tunnels to try this on.
Dry ice at our local market is $1.29 a pound. It's heavier than I expected; my half pound was only good for about 6 holes. If the system works, I'll probably need about 20 pounds!
