I've been battling a mole problem for the past 4 years. I have tried everything on and off the market. From spring traps, repellents and gas bombs. One time I set off so many gas bombs that my entire yard had a green haze rising out of the ground. Looked like a Hollywood cemetery scene. Absolutely nothing has worked. I bought this Molecat while at the Washington State Fair, went home and set it. Less than 24hrs later..."pop"....one dead mole. Finally a win for me!!!
