Long Life Slug Nematodes 280g (20m²)

Long life slug nematodes are supplied as slow-release pearls designed to help manage slugs in garden soil. Once applied, beneficial nematodes are introduced gradually, helping limit slug activity around plants, borders, raised beds, and containers.

Slug nematodes for use in garden soil

The nematodes are held within small gel-based pearls that begin to break down after watering. As they disperse, the nematodes move through damp soil where slugs are active, helping reduce feeding on leaves and roots.

Gradual release for extended soil activity

This pearl format allows nematodes to be released over time rather than in one dose. The staged release helps maintain activity in the soil for longer during each treatment period, supporting more consistent slug management.

Reapplication guidance

For continued control, repeat treatments are recommended. Reapply approximately every six weeks during periods when slugs are active.

The extended shelf life means the product can be stored and used when needed, allowing flexible timing rather than immediate use.

Application method

Apply around 15g per square metre (roughly one and a half teaspoons), spreading evenly across moist soil. Water thoroughly after application to activate the nematodes and ensure even distribution.

When to apply in the UK

Use during cooler parts of the day such as evening, or when weather conditions are damp or overcast. Soil temperature should be at least 5°C. Keep soil moist for three to four weeks after application to support movement through the soil.

Typical application periods are early spring (March to April) and autumn (September to October).

Frequently Asked Questions

What does “long life” mean?
It refers to the extended storage period. Unlike standard nematodes that need to be used quickly, this format allows you to store and apply when needed before the expiry date.

Do I need to apply more than once?
Yes, repeat treatments are needed for ongoing control. Reapply roughly every six weeks during active periods.

How do these nematodes work?
They are released from the pearls after watering and move through moist soil to find slugs.

What area does one pack treat?
Each pack covers up to 20m² when applied at the recommended rate.

When should I apply them?
Apply in cooler, damp conditions when soil temperatures are above 5°C.

How long should the soil stay damp?
Maintain moisture for three to four weeks after application.

Can I use the pack in stages?
Yes, you can apply smaller amounts as needed, provided the product is stored correctly and used before the expiry date.
