Nemaslug 2.0 slug nematodes are a natural organic pest control for reducing slug damage in planted beds, borders and vegetable plots. These slug nematodes are microscopic transparent worms that live in the soil and feed and multiply inside slugs they come into contact with. These nematodes are also known as Phasmarhabditis californica. Unlike synthetic pest control options, these highly specific natural predators will hunt day and night to protect your vegetables from unwanted intruders while leaving other beneficial insects alone.

How does it work?

After being applied to moist soil, the nematodes will seek out any pest slugs below the ground. As slugs move around and towards your plants, they will pick up nematodes, which will enter through openings in the slug. Within days the slug will stop feeding, and most die within a week. This usually takes place beneath the surface, so no trace is left in your vegetable beds. The nematodes will continue to feed and breed, expanding their population, range and effectiveness until food becomes scarce.

How do I use them?

Nemaslug is supplied as a dry powder which can be mixed with water in a watering can and then applied to the area you want to protect. We advise applying them after the last frost but early in the growing season to prevent slugs from pressuring young plants. Once applied, try to make sure that the soil doesn't completely dry out to ensure that the nematode population remains healthy and strong.

Is it safe?

Nematodes are completely natural and prevalent in most gardens throughout the UK. Nemaslug predatory nematodes are simply a more precise and effective version, which will only target the local slug population. They are designed for use where pets and other wildlife are present,

When is the best time to use Nemaslug?

The best time to use these nematodes would be when the soil temperature is reliably above 5°C, usually by the end of February or March. They can be used all through the warm part of the year up until around October. Of course, if you wanted to use them in a covered environment where the temperature will not drop below 5°C, you could use them year-round.

Application Advice:

1. Dissolve the entire contents of the pack in a bucket containing 4L of water to create a solution.
2. Stir vigorously and then take 500ml of the solution and add it to a 5L watering can fitted with a coarse rose and fill with water.
3. Apply this to a 5m² area
4. Repeat steps 2 and 3 until the whole area has been treated

In total, you should go through 8 watering cans (40L of water) and cover a 40m² area. For the larger 100m² pack, simply start with 10L of water for the initial solution and apply with 20 watering cans to a 100m² area.
