Common Grape Hyacinth pests — FAQ
What is eating my common grape hyacinth?
Common Grape Hyacinth (Muscari botryoides) is generally very hardy but aphids cluster on flower spikes, and narcissus bulb fly can attack the bulbs. Squirrels and mice dig and eat the bulbs in autumn and winter. Slugs nibble emerging foliage. This species is largely trouble-free; its main vulnerability is bulb predation by rodents.
