What's eating my garden beet?
Beet leaf miner (Pegomya hyoscyami)
Signs: White or pale-green blister mines in leaves; heavily mined leaves dry out and die
Control: Crush mines between fingers to kill larvae; remove and destroy affected leaves; cover with fine mesh to prevent adult fly access
Black bean aphid (Aphis fabae)
Signs: Dense colonies on young shoots and leaf undersides; sticky honeydew, leaf curl, reduced vigor
Control: Squash small colonies early; insecticidal soap; encourage hoverflies with umbellifers nearby
Slugs and snails
Signs: Holes in young leaves; roots scarred at soil surface; seedlings eaten off
Control: Evening patrols; iron phosphate pellets; rough barriers (grit, bark) around rows
Birds (pigeons, sparrows)
Signs: Seeds scraped from surface; seedling leaves pecked and torn
Control: Cover seedbeds with fine bird-proof netting until plants are well established

Garden Beet pests — FAQ
What is eating my garden beet?
Garden beets are commonly damaged by leaf miners (the larvae that blister leaves), aphids on young shoots, and slugs targeting seedlings and roots. Birds — especially sparrows and pigeons — peck at germinating seeds and young leaves. Deer and rabbits graze the leafy tops. Leaf miner is the most persistent and widespread threat.
