After you spent many hours of planting bulbs, the last thing you want to see are squirrels digging them up. Squirrels love to eat flower bulbs and have a keen sense of smell for finding them. To keep squirrels away, you need to make your bulb area less desirable to squirrels so you'll be able to enjoy your beautiful flowers.
Sprinkle a small amount of used cat litter over the area where your bulbs are planted. This will give off the odour of a nearby cat and keep squirrels away.
Sprinkle blood meal around the border of your bulb garden. The odour helps keep squirrels out of your bulb garden.
Place chicken wire over the bulbs. Measure out the bulb bed, then unroll the chicken wire and cut the amount you need. Lay wire over the bulb bed. Weigh the corners down with rocks or bricks. Cover the chicken wire with an inch of compost or organic mulch, and remove the rocks or bricks if you wish. If you had planted bulbs earlier, remove any mulch before applying the chicken wire.
Make an anti-squirrel spray. Bring 1 quart of water to a boil. Remove from heat and add 2 tablespoons cayenne pepper and ½ teaspoon hot sauce. Allow it to cool to room temperature. Pour into a sprayer and spray the bulb area and plants.
Sprinkle cayenne pepper over the area. Squirrels hate the smell of cayenne pepper.
If you are growing plants bigger than the open spaces of the chicken wire, simply cut the chicken wire to accommodate the larger plant base.
