Most cost effective system I have ever used.
I have spent over $1000 on mole bombs, traps, electronics, and weird liquid concoctions. Only verified 2 moles in over 5 years. The first night I set out the Molecat, scratch one mole. I have identified multiple moles over my 1 acre. In one week the Molecat has gone off three times with no further hills in those areas. Most impressive system.
