We seem to return to is thread at least once a year when the rodents wreck havoc upon our crocus. Since I live in an area without predators other than a stray cat on occasion, other measures are required which involve either trapping and relocating the rodents or removing them in other ways. I can tell you that it can become a full time occupation. I removed 60 squirrels one year just by setting a Have-a-hart trap and taking the squirrels on a ten mile ride. It is either them or your bulbs as I see it. Arnold
