Nemaslug slug nematodes, stop slugs destroying your plants in your garden. Once the nematodes are applied the slugs stop feeding after a few days and die in a week. For total control apply every 6 weeks. Start your slug control early and apply at least a week before planting to ensure your garden is safe from slugs.

Slug nematodes are microscopic, transparent worms, which feed and multiply inside the slug. Easy to apply and completely safe to use around children, pets and wildlife, making it the perfect solution for organic gardening.

The nematodes come complete with instructions and can be applied using a watering can or nematode applicator. You just apply to moist soil when the soil temperature is above 5ºC (41ºF) and ensure the soil does not dry out for at least two weeks after applying nematodes. Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied the nematodes.
