Pest identification
What's eating my yellow crocus?
Birds (sparrows, house sparrows, starlings)
Signs: Yellow flowers systematically pecked open or demolished — yellow forms are the most heavily targeted crocus colour.
Control: Stretch black thread or humming tape just above the flowers; move pots to a sheltered spot during peak bloom.
Squirrels and mice
Signs: Corms dug up and eaten; patches fail to emerge or are drastically thinned.
Control: Plant under wire mesh or in wire cages; cover with grit after planting.
Aphids
Signs: Colonies on stems and leaf bases in spring; sticky honeydew; slight leaf distortion.
Control: Insecticidal soap spray; plants are short-lived in leaf so treat early.

Yellow Crocus pests — FAQ
What is eating my yellow crocus?
Yellow Crocus (Crocus flavus) is a prime target for birds — yellow-flowered crocuses are pecked at far more frequently than purple or white forms, likely due to their visibility. Squirrels and mice dig corms eagerly. Aphids may colonise spring foliage, and vine weevil grubs can damage corms in heavy soils or containers.
