There are woodchucks and/or rabbits living under my shed. How can I make them find a new home?
I'm in Massachusetts where it is illegal to trap them or to catch & relocate them.
I've tried used cat litter and flooding with the hose, but failed.
Some hunting stores will sell fox or coyote urine. I didn't believe it either but for a startling price you can buy a little squeeze bottle. The smell makes them think a predator is in the neighbourhood and they may move along.
If they do you can backfill the hole with gravel and top with a plug of chicken wire.
This is not a guaranteed solution but you have limited options.
Have a dog that likes to hunt come and visit for a while. Check for a local falconer or bowhunter too. Hunting season appears to be closed for deer season, but will then be open through February on rabbits, year-round on groundhogs (and what dogs do by themselves does not fall under the jurisdiction of the DFW.)
Camphor and/or mothballs are other approaches to the "odor them out" method.
