I bought a set of 4 Trapline mole traps which turned out to be rather flimsy wire devices with a spring costing $6 each. I don't know if our moles in Tennessee are bigger than the ones the manufacturer has in California, but there's no way these little devices can kill one of our moles.
I wrote to the maker and he said it should work fine. Well our moles figured out a way to spring the traps and bypass them in the tunnel, and also drag them away so I couldn't retrieve them!
I wrote the owner at www.TraplineProducts.com and got NO REPLY! A good businessman might have replaced my lost traps with the larger sized gopher traps--at least one so I could try it out.
