Slug nematodes (Phasmarhabditis californica) are microscopic worms that naturally target slugs in the soil. When applied, the nematodes seek out slugs, enter their bodies, and feed from within.

Within a few days the slugs stop feeding and die shortly after. Safe for use around pets, children, and wildlife, these nematodes for slugs in UK gardens offer a simple, chemical-free way to protect plants.
