GARDENERS are battling a huge rise in “sleepless slugs” experts warn.

The UK is seeing a huge slug population explosion due to the warmest winter on record and a wet summer in 2015.


Slugs have kept eating and breeding throughout the year, instead of going into hibernation as usual, because the temperature remained relatively high over the winter.

The warm winter has also meant an abundance of food supply for the slugs, meaning they are much bigger than usual.

Pippa Greenwood, featured on Radio 4’s Gardeners’ Question Time yesterday and urged gardeners to spend the bank holiday weekend manually hunting for slugs.

“A damp evening is ideal,” she said.

“Look out for the eggs as well as the slugs themselves.”

“They’re a couple of millimetres in diameter and are often in clumps.”

She also advised laying down natural nematodes such as Nemaslug.

“You can buy several million at a time off the internet,” she said.

“They’re totally harmless to other wildlife.”


Gardeners can help prevent slugs from eating their plants by:

  • Removing cover for slugs such as leaves and bricks
  • Putting copper tape around plants
  • Creating a rough area near their plants with crushed glass or sand
  • Putting plants by ponds so water-dwelling predators of slugs, such as frogs and newts, can keep their population down
  • Placing plants that repel slugs – such as those from the geranium family – next to those that attract them, such as Hostas
  • Chemicals should be avoided because they could be poisonous to other animals, such as birds, cats and dogs. If you do use slug or snail pellets, the Royal Horticultural Society recommends iron phosphate pellets because they are less toxic than Metaldehyde.
  • Nemaslug nematodes- which kill slugs by feeding off them parasitically are 100% organic and are safe for children, birds, cats and dogs and work extremely well even in wet conditions.


Normal seasonal weather conditions, cold, frosty winters and dry summers, usually keep the slug population down, but this winter was significantly wamer with December 2015 being the warmest since records began in 1910, with temperatures sitting at an average of 7.9°C.

Fact: Slugs remain active when temperatures remain above 5C, and with little snow or frost, they have simply kept going through the cold months. They lay up to 200 eggs per cubic metre, and it’s estimated that the average UK garden could be home to up to 20,000 slugs (unless you use Nemaslug of course).


If you have already applied Nemaslug this season then you will be already be seeing the benefits, but if you haven’t now is the time to start tackling the pests.

Chafer Grubs, their lifecycle and when to treat them with nematodes


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.


Nemaslug Slug Killer is the simple organic solution for slug control in your garden that is safe for children, pets and wildlife.

A regular regime of using Nemaslug every six weeks is the best way to keep slugs at bay throughout the growing season.
