Slugs are the number 1 garden pest, feeding on the foliage, flowers, stems and roots of plants. Slugs come in all shapes, colour and sizes, including the small, black, sneaky ones which live underground and the fat frilly monsters up to 4inches/10cms long. The good news is that Nemaslug® will polish them all off naturally. Nemaslug® should be applied OUTDOORS between March and October. Each unit contains 12 million nematodes. Suitable for organic growers. Leaves no residue - once applied, all you see is your plants.


Nemaslug® is totally harmless to children, pets and wildlife. Nemaslug® is so green that birds & hedgehogs can happily eat slugs after application.
• Nemaslug® is easy to use - simply mix the harmless powder with water and apply to the soil
using a watering can or with a hose-end feeder.
• Nemaslug® works for 6 weeks - even in wet weather which is just when your plants need protection.

How to use:
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 a 5 litre watering can fitted with a very coarse rose and fill with 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 40 m2 (50sq yds). Also easily applied with a recommended garden hose applicator – see inner sleeve or visit

Nematode application methods – Nematodes are supplied as powders which are mixed with water and applied directly to the soil with a watering can, hose-end feeder or sprayer. You should use a coarse rose on the watering can a Haws No 7 is recommended, or we find the hose-end feeder very successful.

  • Nemaslug

    Posted by Karen Allen on 15th Apr 2019

    We first used this product in 2018. It is easy to apply and effected a dramatic reduction in slug numbers in our garden. The fact that the nemaslugs are delivered as needed (at 6 weekly intervals), makes it very easy to keep on top of the required schedule. Nemaslug is completely safe to use posing no risk to other animals, plants or the soil.

  • Very effective

    I applied the treatment quite late in June after slugs started to eat young plants and it considerably reduced the amount of slugs. There are just a few left that haven’t been in contact with the soil. The standard pack allowed to cover 20 balcony planters 50cm wide.

    This is a great product - my Hostas are slug-free for the first time.

  • Effective and simple to apply

    Posted by Karen Allen on 4th Sep 2017

    Prior to using Nemaslug we had a moderate slug problem, we were using various conventional methods (pellets, barriers etc) with no discernable effect on the slug population. Since using Nemaslug the effect has been dramatic with far fewer slugs in evidence and virtually no damage to plants. I will definitely use this product in future.

  • Goodbye Slugs!

    Posted by Vivian on 21st Jul 2017

    I was recommended this product by a number of friends because it is safe for bests and wildlife. Used it this week for the first time and have seen a significant reduction in the number of slugs. Will definitely be ordering this product earlier this year and using it as this year a lot of my bedding plants and plantings were decimated by slugs!

  • so glad i bought this

    Posted by Pauline Doran on 1st Jun 2017

    As I've tried many products over the years for my invasion of slugs I decided to try nemaslug slug killer. After a heavy shower of rain, I mix up the packets as described on packet . Two days later I didn't see any slugs, now a week on and still no sign. I would definitely buy again.
