Slug damage continues to take a heavy toll on UK gardens, with many green-fingered enthusiasts facing the frustration of ruined vegetables, shredded ornamental plants, and failed seedlings year after year.
Whether you're growing in containers, raised beds, allotments or traditional borders, slugs remain one of the most persistent and destructive garden pests.
Their damage is often underestimated until it’s too late. Slugs can decimate young crops overnight, targeting tender growth when plants are at their most vulnerable. That’s why long-term, preventative slug control is vital for gardeners looking to protect their hard work.
And one of the most effective, natural defences available is Nemaslug® 2.0, a biological slug control that works in harmony with nature and delivers results below the soil surface, where the real damage begins.
Why autumn is a key time
Slugs remain active well into the cooler months and continue laying eggs until soil temperatures drop below 5ºC. By applying Nemaslug 2.0 in autumn, gardeners can target both adult slugs and reduce the number of viable eggs in the soil - halting next spring’s population before it starts.
This final seasonal application offers:
- Early season protection for emerging seedlings and young plants
- Longer-term control by breaking the slug lifecycle
- Peace of mind knowing your garden is defended naturally ahead of the winter
How it works
Nemaslug contains millions of Phasmarhabditis nematodes - microscopic, soil-dwelling organisms that naturally target slugs. Once applied to moist soil, the nematodes seek out slugs, enter their bodies, and release bacteria that quickly kill the host. The nematodes then multiply inside the dead slug and spread out to find more prey, continuing the cycle of protection. Once their food source is exhausted, the nematodes naturally decline to background levels making them an environmentally responsible option for any garden.
Unlike pellets or chemical sprays, Nemaslug remains effective during the wet autumn months. It works in harmony with nature, causing no risk to pets, wildlife, bees, or birds and because it’s applied to the soil, it targets slugs where they live, not just where they feed – an approach unique to beneficial nematodes.
Added benefits of autumn use:
- Soil health is maintained, with no chemical residues or runoff
- Perfect for no-dig and organic gardens
- Ideal for raised beds, greenhouses, and ornamental borders
- Delivered fresh to your door with simple instructions
