Luckily, squirrels don’t tend to take to suet as often as they do sunflower but we do get the occassional report. The real problem tends to be with the “night shift”. Many people simply take their suet feeders in at night. While this very effective, it only takes forgetting it once that leads to a trip down to the edge of the woods to retrieve the feeder. The simplest solution that I have found is Hot Pepper Suet. No, it doesn’t hurt the birds and they will eat it just as well as many of the other formulas. Mammals have very different taste systems from birds and are quite sensitive to the peppers. They will leave it alone. Some do like to rotate the Hot Pepper with their favorite cake. If you do want to do this, remember to wear cloves while handling the pepper cakes.
