They Are Working
They appear to be working. I have had a severe mole problem in the past. I have seen very little mole activity since installing the sonic spikes. The most difficult part for me saw deciding where to put the spikes. They needed to be in the sunlight to recharge their battery and I was wanting to place them close to a tree or in a flower bed so that I would not run over them with the mower. I did keep buy more of them to help with the location problem. I think that I presently have 12 spikes working in our yard. They are kind of pricey, but not as pricey as some things that I have tried in the past. And if they keep working like they presently are, they will be a great bargain, and I can reuse them next year.
