[Tweeters] Repelling rats and squirrels

[GENE BULLOCK via Tweeters]

Cayenne pepper treated "hot" seed and suet repels rats and squirrels, but is expensive. But you can buy cayenne pepper oil and treat the seed and suet yourself. I have also had success against rats and squirrels by using predator guards and a catch tray to prevent spillage on the ground. But the feeder must be far enough from jumping off points.
