i've only had trouble with moles maybe once or twice, they just left a huge trail in my yard of ground up dirt. they didn't give me much trouble, i wouldn't worry about them too much unless you are having serious issues on a weekly basis.
leave the worms here is a green way to get rid of the molls::2 tbsp chill powder,4tsp hot sauces and 4tbsp of dish washing liquid mix with warm water make 2 quarts adjust as needed pore on the moll hills and runs
No they are not. And I don't have groundhogs here. I am blessed with MOLES. TONS OF THEM
Best resolution: chewing gum!!! kind of manual intense but instead of poison or some other natural chemical that will irritate worms or something else......use a small gardening shovel and dig on top of the mole hill till you reach their tunnel. Drop a few pieces of gum into them and cover. Moles will eat the gum and die. No body to take care of!
