If you wish to use Nemaslug during the colder months (generally October - March) UNDERGLASS or in sheltered gardens where the soil is already warm enough then please select this product when ordering.

The soil temperature should be 5ºC (40ºF) or over when applying Nemaslug. The treatment will be much less effective if the soil temperature falls below 5ºC (40ºF) after application. 

Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied Nemaslug.


What is Nemaslug?

Nemaslug, is a natural organic pest control - environmentally friendly and safe for children, pets and wildlife. 

It uses the nematode Phasmarhabditis californica, which was discovered by scientists at the government research institute at Bristol, England.

Nemaslug continues to work well during wet weather - exactly when you need protection against slugs, unlike most other slug controls.

One application of Nemaslug provides 300,000 nematodes for every square metre of soil, giving around six weeks control of slugs, this is generally enough time for seedlings and bedding plants to get well established.

For protection throughout the growing season consider ordering a Nemaslug Programme where we automatically send a pack every 6 weeks.

When should I apply Nemaslug outdoors?

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.

Regularily applying Nemaslug every six weeks is the best way to keep slugs at bay throughout the growing season.

TIP: 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.

If you have a heavy clay area, ensure you apply Nemaslug to well worked soil. Nemaslug is less effective on cloggy clay soil, which has not been worked and/or has become waterlogged.

Nemaslug might affect water snails. To avoid harming them keep the treatment 15 cm (6") away from ponds.


What if I want to use Nemaslug in my greenhouse?

If you want to apply nematodes to your greenhouse when the outdoor soil temperature is <5ºC (40ºF) please order this product. Underglass/indoor usage category - all nematodes featured in this section are sent 365 days a year.


Which pack size do I need?

Nemaslug comes in two pack sizes to treat small or medium gardens up to 40m2 (50 sq.yds) and larger gardens or allotments up to 100m2 (125 sq.yds).
