For gardeners managing larger planting areas, Gardening Naturally Vine Weevil Nematodes large garden pack offers reliable biological control of vine weevil larvae across borders, containers and planting beds. Vine weevil larvae feed on plant roots beneath the soil surface, causing sudden plant collapse and serious damage to ornamental plants and fruit crops. Treating the soil with beneficial nematodes targets the pest at its most destructive stage. Effective Biological Vine Weevil Control This product contains Heterorhabditis bacteriophora, a species of beneficial nematode widely used in natural pest control. Once introduced into moist soil, the nematodes actively seek out vine weevil larvae feeding around plant roots. After entering the larvae, they multiply and spread through the soil, helping reduce the pest population across the treatment area. Ideal for Large Gardens This large coverage pack is suitable for: Garden borders Raised beds Ornamental planting schemes Strawberry beds Large container collections It provides coverage for up to 100 m², making it ideal for larger gardens or multiple treatment areas. Best Treatment Times Apply when vine weevil larvae are active in soil: Spring (March–May) Late summer to autumn (August–October) Nematodes require soil temperatures above 8°C and moist soil conditions. Note: These are a live product and have an expiry date of around 2 weeks. Easy Application Simply mix the nematodes with water and apply around plant roots using a watering can or applicator.
