Lawn Pests and Nematodes

Lawn Pests – Leatherjackets & Chafer Grubs

Leatherjackets are about 25mm (1″) long, greyish black, legless and with no distinct head. They are the larval stage of the crane fly (daddy long legs) which appear towards the end of August and lay eggs within days. These hatch within two weeks and start to feed.

Chafer grubs are creamy coloured, about 15mm (0.6”) in length with distinct legs (unlike vine weevils). Chafer beetles emerge from lawns and lay eggs, which hatch into grubs feeding. They burrow deeper for winter and lie dormant before surfacing in spring to emerge as beetles.

Both leatherjackets and chafer grubs attack grass roots resulting in slow growth and yellow patches. Grass is easily pulled up, with little or no root.

Wildlife, such as foxes and badgers, can create damage by digging to search for grubs, as do rooks, magpies, crows and woodpeckers – a good sign of an infestation. Dig up a piece of turf and inspect it for pests.

Some things you might not know about slugs

Potatoes are susceptible to slug attack later in the season than most other plants.  This means that you can delay applying Nemaslug till 6-7 weeks before harvest, when the tubers are most likely to be eaten by slugs.

Slugs will feast on your fruit and vegetable crop, including your:

  • Lettuce
  • Celery
  • Cauliflower
  • Cabbage
  • Brussel Sprouts
  • Asparagus
  • Strawberries
  • Tomatoes
  • Slugs will also attack the leafy parts of plants, especially hardy ornamentals like Hostas


Some things you might not know about slugs:

  • Slugs are hermaphrodite (have both male and female sex organs).
  • Each Grey Field Slug can have up to 90,000 grandchildren.
  • Slugs have approximately 25,000 teeth.
  • Slugs consume around twice their own body weight each day. If you consider that an average slug weighs 0.1 oz, it will consume an amazing 28oz of plant material in a growing season.
  • Young slugs tend to stay underground, feeding on humus (decaying organic matter). This creates an unseen menace, developing out of sight and just waiting for your young seedlings to be planted.


Slimy slug facts…

  • Each slug lays about 300 eggs in batches of up to 50 in crevices in the soil.
  • Slug eggs are slightly oval in shape, white in colour and measure 2-3 mm in diameter.
  • They hatch in 3 weeks in the spring, whilst eggs laid in the autumn can over-winter before hatching.
  • Slugs breed all year round. There are two overlapping generations usually with peaks of egg laying in March-April and September-October.
  • In northern Europe the life cycle takes 12-15 months.
  • Britain is the slug capital of the world.
  • Our moist climate, without the extremes of hot or cold, is ideal for them.
  • Each cubic metre of soil contains on average up to 200 slugs.

Know your British Slugs

Slugs can be a gardeners worst nightmare and can cause havoc in the garden.  It pays to know your slugs as that way you can combat them effectively with Nemaslug, your natural nematode pest control – environmentally friendly and safe for children, pets and wildlife.

[tabs tab1=”Grey Field Slug” tab2=”Garden Slug” tab3=”Keeled Slug”  tab4=”Black Slug”  layout=”horizontal or vertical” backgroundcolor=”” inactivecolor=””]

[tab id=1]

The most common and serious slug pest. Highly variable in colour (but usually light grey or fawn).  It measures 3 cm (1.5 inches).




[tab id=2]

Similar in size to the grey field slug, but with a much tougher skin. Usually darker in colour (grey to black), with their underside a distinctive yellow, which also characterises their slime trail.


[tab id=3]

Grey in colour with a ridge down the back, they are generally larger than the Grey Field Slug (about 6 to 7 cm or 2.5 inches). On the whole they are regarded as mainly subterranean in behaviour, living and feeding under ground.


[tab id=4]

This one is much larger than the others, measuring up to 20 cm (8 inches) and is black in colour (though the young stages can be yellowish with dark tentacles). As such, it can be very conspicuous in your garden.  This may lead gardeners to conclude that this is the most common slug and is causing all the damage, when in reality the real menace (the Grey Field Slug and/or the Garden Slug) is resting underground. There are also some sub species of this slug that are similar in most respects, except that they have a distinctive reddish brown to yellow colour.

How quick is the British Snail?

For the first time Scientists at Exeter University have been studying the British Snail’s behavioral patterns and the answer is:

“1 metre per hour, according to Dr Dave Hodgson and his team at Exeter University,  who claims that they can cover a typical garden in just one night.”

The study which was initially intended to discover how the Lungworm, an infectious parasitic worm was spread by slugs and snails.

Lungworm which is typically spread by the consumption of Snails and/or dog poop, can be fatal in dogs, and owners are encouraged to be aware of the risks associated with the parasite.

Speedy Snails travel at 1 metre per hour

FACT: Snails often follow each others slime trails to piggy-back on the slime trails of other snails!

It’s time to apply Nemaslug

Following the recent wet weather, slugs and snails will be having a “field day” in your garden, and with the risk of frost almost over most areas of the UK should be safe to make their first application of nemaslug.

Nemaslug Slug Killer Tips:

Always put your Nemaslug / nematodes in the fridge as soon as they have been delivered.
If applying with a watering can make sure your watering can and rose is clean & clear of debris.

Don’t forget that the air temperature is not the same as the soil temperature – visit our gardening weather section for the soil temperature in your area.
Before applying your nematodes, have a quick hunt around for slug hotspots and treat those areas with a little extra Nemaslug.

Apply your Nematodes at the end of the day just before sunset to reduce the risk of the nematodes “drying out” before they work into the soil.
