Squirrels can be a real nuisance in your yard or garden when they are eating up the bird seed and devouring your plants. On the other hand, resorting to poisons or deadly traps is an unnecessary environmental hazard. Using pepper spray as a natural repellent to get rid of squirrels is a sensible and kind compromise. Squirrels hate the smell and taste of pepper. Mix up a batch of squirrel repellent in the kitchen. Maybe you'll get to see a few birds in the garden this season.
