What is Nemaslug?
Nemaslug, is a natural organic pest control - environmentally friendly and is 100% safe for children, cats, dogs, other pets and wildlife.
It uses the nematode Phasmarhabditis hermaphrodita, which was discovered by scientists at the government research institute at Bristol, England.
Nemaslug controls all common species of small to medium sized slugs (up to 8cm - 2.5-3 inches). Start your Nemaslug control regime early in the growing season and you will be able to target the young slugs growing under the ground feeding on humus.
Young slugs tend to stay underground, feeding on decaying organic matter, developing unseen and waiting for young seedlings to be planted. They breed all year with two overlapping generations. Peak egg laying is Mar-Apr and Sept-Oct.
How does Nemaslug work?
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.
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.
Unlike some controls, Nemaslug continues to work well during wet weather - exactly when you need protection against slugs.
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 see our 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 40 sq.m (50 sq.yds) and larger gardens or allotments up to 100 sq.m (125 sq.yds).
To calculate your area measure the width and length of the area to be treated and multiply them by each other e.g. 10m x 10m = 100 sq.m or 5m x 20m = 100 sq.m
