You’ve come to best and right place to learn about trapping moles. BUT, you also have to do your homework and research. The ARCHIVES on this website offers a wealth of information and will answer all of your questions. We’ve all been through what you’re experiencing at one time or another. You also get to learn what’s going on in other parts of the country pertaining to types of mole traps, subspecies of mole, mole habits and habitat regarding your subspecies, soil types, trapping techniques, etc. If you have trouble negotiating the website’s ARCHIVES, do a Google Search “Mole Trapping, Trapperman Forums.”
What type of soil are you trapping in? Are you trapping the surface foraging/feeding tunnels or the deeper tunnels? What other types of mole traps have you used prior to using the No-Mole? Have you tried any of the scissor traps (OOS, Talpex, etc) or Trapline Products (Steve Albano) mole traps?
No need to wear gloves unless your soil gets muddy or you have to deal with Sandburs or Fire Ants. Unless you somehow squeezed urine, feces, musk juice or other pheromones from previously caught moles, I doubt scent on your bare hands or traps will bother moles.
If you are trapping in an urban setting, it’s not unusual to trap 2-3 moles in a 3-5 day trapping period then get a call back 1-2 weeks later. Moles are supposed to be territorial. It may take some time for neighboring moles to find out the moles you caught are gone before re-colonizing their tunnels. Mole population density, climate, availability of earthworms, beetle larvae, soft bodied insects. etc. also come into play. Unless you live in a rainy climate, those homeowners with the greenest landscape will be your best mole customers!
Put your hands in the dirt and set some mole traps! Experience is the best teacher! Good luck.
