The Giant Destroyer Garlic Tunnel Tubes Mole & Gopher Repellent - Repels Moles & Gophers in Gardens & Lawn Areas - Highly Concentrated Garlic Oil Animal Repellent - 20 Tubes

This is a humane way to repel moles, gophers and groundhogs from your yard. We used this last year and it worked. We made a hole into their tunnels and dropped it down. We did it about every five feet. Yes, our yard smelled like garlic for a day or so. Was it worth it - YES!! We have dogs, they didn't care. They popped up another tunnel and we did the same thing. Now they are gone! It worked two years in a row. This is really, really strong smelling! make sure you read the directions and use it the right way. My wife was trying to put them in without opening them. Honestly, it might have worked, but better to use it full force.
