Gardening Naturally Slug Nematodes 40sq.m

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.

How Nematodes for Slugs Work in the Soil

Slug nematodes occur naturally in soil but in low numbers. By applying additional nematodes, you increase their presence and quickly reduce slug populations. Once inside the slug, the nematodes feed and multiply, spreading to other slugs in the area. This breaks the slug life cycle and helps protect your plants from root and leaf damage.

When to Apply Nematodes for Slugs in UK Gardens

For best results, apply nematode slug control every six weeks during the growing season when soil is moist and above 5ºC. Starting treatment before planting gives protection as young plants establish. Applications can continue through spring, summer, and autumn to maintain control and reduce future slug problems.

How to Apply Slug Nematodes Around Plants
