Was in my feedstore today and they had a large display of this product called shakeaway. They seem to come in different "flavors" for different animal issues. They had one for rodents and listed mice, moles, voles, and rats along with chipmunks etc.. says you just sprinkle around..they have a website too.. shake-away.com seemed a bit pricey for a small can it was like 13 bucks.. I have a stupid rat that seems to evade my cat and other cats and has taken up residence under my watergarden/koi pond and even chewed a hole somewhere in liner because my water level went down.. I find his tracks in fresh snow.. and he has avoided my trap efforts as well. I hate to revert to poison because of my own animals and stuff in the area. Just wondering about this stuff..Told my barn cat I was going to stake him to the area. He has brought me rats before but cant seem to get this one.. who has now cost me money and time in the spring to dismantle many many rocks and find the leak he created!!!!! Oh and I know it is a rat because I saw him scurry in the rocks once.
