NemaControl Vine Weevil is a highly effective biological control treatment for vine weevil larvae using naturally occurring beneficial nematodes (Steinernema kraussei or Heterorhabditis bacteriophora). These microscopic organisms actively seek out and destroy vine weevil larvae in the soil before they can damage plant roots. Safe for use in ornamental beds, borders, planters, nurseries, and polytunnels, NemaControl offers reliable pest control without harmful chemicals.
Apply during the key activity period for larvae (typically March–May and August–October) to prevent costly damage to your plants.
Features & Benefits
✅ 100% natural pest control – safe for children, pets, wildlife & pollinators
✅ Targets damaging vine weevil larvae before they reach adult stage
✅ Easy-to-apply via watering can or sprayer
✅ Effective in protected and open environments (greenhouses, nurseries, borders)
✅ No harvest interval or re-entry restrictions
Applications & Uses
NemaControl is ideal for:
Commercial nurseries and horticultural operations
Garden centres and public planting schemes
Ornamental plantings, hanging baskets, raised beds, planters
Residential gardens, balconies, and polytunnels
The nematodes work by entering the body of the vine weevil larvae, releasing a bacteria that kills the pest within 24–72 hours. The nematodes then reproduce within the host, continuing the control cycle.
Application Rates & Timing
Apply when soil temperatures are consistently above 5°C. Best applied early morning or evening and during damp conditions to avoid UV exposure.

What Damage Do Vine Weevils Cause?
Vine weevil larvae are one of the most destructive pests in UK gardens and nurseries. These C-shaped grubs feed on the roots of a wide variety of plants including heucheras, fuchsias, primulas, strawberries, rhododendrons, and many container plants. Severe infestations can result in:
Wilting and yellowing of leaves
Sudden plant collapse
Root loss leading to death of young or potted plants
Early control with nematodes is essential to prevent widespread damage.
