The evidence of a mole running through the yard can be so frustrating. I spend a lot of time working hard in the yard and a mole comes along and leaves his burrowing mounds across my front lawn. A mole must not be a creature to sit in one place very long because it can leave a long trail in no time at all. No doubt about it, that mole has got to go.
I purchased a Windmill Mole Chaser from Harbor Freight to deal with the mole problem in my yard. The concept seems simple enough. A rotating windmill planted in the yard creates a sound that echoes underground. Moles must have sensitive ears. Since they are blind creatures they must depend more on their hearing. Apparently the sound created from the windmill sends them off in another direction.
A Windmill Mole Chaser deals with problem moles without using dangerous toxins or traps. The blades are 18" long by 2-1/2" wide. The blades are mounted to a bearing which allow the windmill to turn. A directional blade rotates the windmill so that it works with the wind. The assembly is mounted to a small pole which is simply inserted in the ground.
I looked at a solar powered mole chaser that emitted a periodic ultrasonic sound that chased the moles away, but I figured the ultrasonic sound would drive the dogs in the fenced in back yard crazy too. I do not have much of a problem with moles in the back yard. Think about it. It will come to you.
I monitered the area where I installed the windmill mole chaser and this product does work. The area where the windmill mole chaser is installed shows no signs of mole activity. The only drawback that I found is the welding is weak.
If only the cat was as good as the dogs with getting rid of moles I would not have a mole problem.
