Pest identification
What's eating my chantenay carrot?
Carrot fly (Psila rosae)
Signs: Larvae tunnel through roots leaving rusty brown channels; foliage turns red-yellow; unmanaged infestations can destroy over 50% of the crop.
Control: Grow under insect-proof mesh (Enviromesh) from sowing to harvest; erect a 60 cm vertical barrier of polythene sheeting around the bed; avoid thinning at dusk when the fly is most active.
Willow-carrot aphid (Cavariella aegopodii)
Signs: Colonies on foliage; sticky honeydew; transmits carrot motley dwarf virus, reducing yield by up to 50%.
Control: Mesh covers exclude the flying adults; reflective mulch deters landings; insecticidal soap for uncovered beds.
Slugs & snails
Signs: Ragged holes in leaf tops and occasional shallow scoring on young roots in damp, heavy soils.
Control: Ferric phosphate pellets; nematodes (Phasmarhabditis hermaphrodita) applied to moist soil; improve drainage.
Carrot moth caterpillar (Depressaria radiella) / cutworms
Signs: Caterpillars shred carrot foliage or cut seedlings at ground level, primarily in late summer.
Control: Hand-pick caterpillars in evening; Bt spray on young caterpillars; disturb soil around plants to expose and desiccate cutworm larvae.

Chantenay Carrot pests — FAQ
What is eating my chantenay carrot?
Chantenay carrot's short, stout roots are prime targets for carrot fly larvae, which tunnel through the flesh. This is by far the most damaging carrot pest in the UK and US. Willow-carrot aphids coat foliage and vector viruses. Slugs chew leaf tops in wet seasons. Physical barriers are the most reliable defence.
