"... In particular, the blood meal will be very effective - against both squirrels and rabbits. You can buy blood meal at your local garden supply store. Scatter the blood meal around the perimeter of your garden and in between your rows - following the package directions (Don't be stingy!) Be sure to reapply after rain or watering."
