Applying Nemaslug Nematodes
There are two main methods for applying Nemaslug - with a watering can with a coarse rose or by using a hose end feeder.
40m2 Nemaslug - Watering can application:
1. Dissolve the entire contents of the pack in a bucket containing 4 litres of water to create a stock solution.
2. Stir vigorously and immediately take 0.5 litre of the stock solution, add to an empty watering can fitted with a very coarse rose (≥1.4mm diameter holes) and fill with 4.5 litres of water.
3. Apply the solution to an eighth of the soil area to be treated.
4. Repeat steps 2 and 3 until the whole area is treated. 5. Water the treated area after application.
This pack fills 8 watering cans of 5 litres and treats up to 40m2 (50sq yds). Also easily applied with a recommended garden hose end feeder.

The soil temperature should be 5ºC (40ºF) or over (this is also when plants start to grow). Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied Nemaslug. Metaldehyde based slug pellets are reported not to be effective below 7ºC.
Use the whole pack before the expiry date, which is marked on the inside of the pack and will be at least a couple of weeks. Apply in a broad band around your plants to increase the chances of slugs coming into contact with the nematodes.
Potatoes are susceptible to slug attack later in the season than most other plants. So you can delay applying Nemaslug till 6-7 weeks before harvest, when the tubers are most likely to be eaten by slugs.
A regular regime of using Nemaslug every six weeks is the best way to keep slugs at bay throughout the growing season.
Nemaslug facts:
- Nemaslug uses the nematode Phasmarhabditis hermaphrodita. One application of Nemaslug provides 300,000 nematodes for every square metre of soil, giving at least six weeks control of slugs. This is generally enough time for seedlings and bedding plants to get well established.
- Nemaslug is easy to apply and does not leave any unsightly residues.
- Slugs treated with Nemaslug will stop feeding in 3 days and die in about a week. The majority of the slugs will die underground, so don’t expect to see dead slugs lying around.
- Apply to moist soil. The soil temperature should be 5ºC (40ºF) or over (this is also when plants start to grow). Nematodes are capable of surviving the odd frost, so don’t worry if the temperature falls after you have applied Nemaslug. Metaldehyde based slug pellets are reported not to be effective below 7ºC.
- Unlike some controls, Nemaslug continues to work well during wet weather – exactly when you need protection against slugs!
- Nemaslug might affect water snails. To avoid harming them, keep the treatment 15 cm (6″) away from ponds.
- If you have a heavy clay area, ensure you apply Nemaslug to well worked soil. The product is less effective on cloggy clay soil, which has not been worked and/or has become waterlogged.
- Nemaslug comes in two pack sizes to treat small or medium gardens up to 40 sq.m (50 sq.yds) and larger gardens or allotments up to 100 sq.m (125 sq.yds).
