A few posts back I told you about my latest attempt at tackling our mole problem. It was with a Solar Mole Chaser.
They were $10 a piece at Harbor Freight. I got four. On the box it says it covers a 6000 sq ft area, or a litter bigger than a 40 foot radius circle, if my high school algebra memory is still correct: pi r squared.
To sum up: Solar - yes. Mole Chaser - not so much.
Take a look:
Save your money. If you're keeping score at home that's Moles - 4 / Rancher Ron - 0.
