P3 International Sol Mate Solar-Powered Mole and Gopher Repellent Device

The moles came out in force a few weeks ago. We already had some mole deterrents such as this but after 3 years, they have started to work only intermittently. Tired of the Moles tearing up my yard and displacing/stealing my dirt, I ordered 3 of these for our backyard and moved the intermittently working ones to the side yard. They seem to be working so far, had them for a few weeks. The backyard doesnt havent any new holes or mound however, it now seems that the Moles are mocking me, they have moved to the side yard and dug up the area BETWEEN the older repellants there! Now it seems I will have to order a few more....BTW, we have a Shih Tzu and then her friends (another Shih Tzu and a Beagle) and these dont seem to bother them at all.

I got 4 of these, one for each direction of my house. They do work but they must be put ALL the way in the ground. These vermin are deep tunneling and eas roots, so they can't work if if they are barely placed in the dirt. We put them in and there's less than one inch from the top base to ground and have had no more problems.
