Well, Jo Ann and Polly, It might just be a coincidence, I don't know for sure but I strongly suspect it might keep voles out--that's why I asked the question if anyone else has noticed any such relationship. Voles are a real problem here but I can honestly say I've seen no evidence of any sign of voles in there for the last 15 or 20 years but I have seen little tunnels and runways all over the place in my other gardens where I don't have muscari.
