Squirrels love to eat flower bulbs. My main defense against them is planting bulbs they don’t like. I’m big on daffodils and little spring flowers like the muscari.

Philly.com real estate columnist Al Heavens offers some other strategies in “Outfoxing bulb-thief squirrels.”
* Apply animal urine–your dog’s or the commercially available product from foxes.
* Stake hardware cloth over the sensitive area, but remember to remove it in time to let the bulbs grow up.
