Pest identification
What's eating my tiger nut?
Wireworms (Agriotes spp. larvae)
Signs: Tunnels bored through developing tubers; rotting entry points invite fungal disease; stunted plants with reduced tuber yield
Control: Rotate planting sites annually (wireworms build up in permanent beds); cultivate soil before planting to expose larvae to birds; beneficial nematodes (Steinernema carpocapsae) applied to moist soil
Voles and mice
Signs: Tubers gnawed or entirely removed underground; surface runways visible around plants; large harvest losses in small gardens
Control: Line raised beds with fine wire mesh (hardware cloth) below the soil; snap traps placed in runs; reduce mulch cover where voles hide
Aphids (Rhopalosiphum spp.)
Signs: Yellowing, sticky foliage; colonies cluster on new shoots; weakens plants and can vector viruses
Control: Strong water jets to dislodge; insecticidal soap spray; encourage natural predators (lacewings, ladybirds)

Tiger Nut pests — FAQ
What is eating my tiger nut?
Tiger nut (Cyperus esculentus) tubers are targeted by wireworms, white grubs, and voles underground. Above ground, aphids and thrips attack the sedge foliage. Voles and mice tunnel to consume tubers in garden beds. Being a sedge grown for underground tubers, soil-dwelling pests are the primary threat.
