Preventing squirrels from eating bulbs
This sounds like normal squirrel behavior. Some controls include:
Plant bulbs that squirrels do not like to eat such as: Allium (Ornamental allium), Anemone (Grecian windflower), Chionodoxa (Glory of the snow), Frittilaria, Galanthus (Snowdrop), Hyacinthoides hispanica (Spanish bluebell), Leucojum (Snowflake), Muscari (Grape hyacinth), Narcissus (Daffodil), and Scilla.
Protect newly planted bulbs with a piece of one-inch mesh chicken wire extending at least a foot beyond the edge of the bed and mulch. Sprinkle crushed oyster shells (available at farm co-op stores) over the surface of the garden to deter digging.
Remove access to food sources such as bird feeders. Some squirrel proof feeders may deter squirrels. Rake fallen acorns and other nuts from the ground.
