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 to 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 100sqm (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. 4m x 10m = 40 sq.m or 5m x 8m = 40 sq.m

Question: What is Nemaslug?
Nemaslug is a unique product, containing microscopic worms (nematodes) which seek out slugs and stop them feeding on your plants within 3 days and then kill them.

Question: Why use Nemaslug?
Nemaslug is an effective alternative to chemicals. It is safe to use and harmless to children, pets, birds and wildlife. It also works incredibly well in damp and wet conditions, which is when slugs thrive and do the most damage.

Question: How do I apply Nemaslug?
Nemaslug is applied very simply using a watering can with a coarse rose. Full instructions are on the pack. Application of the standard pack normally takes 30 to 40 minutes. It is important to use the correct amount of water during application since this ensures the nematodes are washed into the soil and gives an even application.

Question: When can I apply Nemaslug?
Nemaslug can be applied any time when slugs are present as long as the soil temperature is 5oC (40oF). We usually stock Nemaslug 365 days of the year, so you can continue to use Nemaslug underglass / in heated greenhouses.

Question: What will Nemaslug control?
Nemaslug will control all common species of small to medium sized slugs up to 8 cm (approx. 3 inches).

Question: How long does Nemaslug work?
One application of Nemaslug will provide at least six weeks control of slugs, we recommend that you re-apply every 6 weeks for the ultimate protection from slugs..

Question: Are there any special precautions?
Only in regards to applying near ponds as Nemaslug might affect water snails. To avoid harming water snails keep the treatment 15cm (6 inches) away from ponds.

Question: Can Nemaslug be used on clay soils?
Nemaslug can be used on clay soils that have been well worked with other organic materials. Do not use if the area you wish to treat is waterlogged or very heavy wet clay.

Question: Is Nemaslug harmful to anything else?
Nemaslug is harmless to other wildlife, pets, birds and children. Its only harmful to slugs and water snails.

Question: Are any special conditions required?
Nemaslug should be applied to moist soil. If applying in hot weather it is better to wait till later in the day when the soil won’t dry out so quickly and the nematodes will have a chance to migrate under the ground during the night. Its beneficial to water it in well after application to ensure you wash all of the nematodes into the soil as they will soon die if they are on the foilage.

Question: What happens if the temperature falls after I have used Nemaslug?
The control may be a little slower. However, the nematodes are capable of surviving even the odd frost.

Question: Will Nemaslug be washed out of the soil during prolonged wet weather?
Unlike some other slug control methods, Nemaslug continues to work well during wet weather – exactly when you need protection against slugs!

Question: Is there any benefit from applying Nemaslug in the autumn?
If you apply Nemaslug in the early autumn you will reduce the number of slugs laying eggs and consequently reduce the new population emerging in the spring.

Question: When is the best time to apply Nemaslug to protect my potatoes against slugs?
The best results are obtained by applying Nemaslug 6 to 7 weeks before harvest. This is when the tubers are most vulnerable to slug attack.

Question: Can I water Nemaslug directly on to plants?
Nematodes live in the soil so, if you can, it is better to apply to the soil. However, if because of dense foliage this is impossible, after application wash them off into the soil with some extra water.

Question: Can I eat produce that has been treated with Nemaslug?
Yes, just wash your fruit and vegetables in the normal way.

Question: Can Nemaslug kill snails?
The nematode used in Nemaslug is a mollusc killer however, nematodes live under the soil and snails tend to stay on the surface, so they don’t come into contact very often. It does have a slight effect on small snails as they remain under the soil for longer.
