Slugs are the gardener’s worst nightmare.
They are impossible to get rid of once and for all, therefore you need to keep up a constant battle to keep them under control. 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.
The Grey Field Slug – The most common and serious slug pest. Highly variable in colour (but usually light grey or fawn). It measures 3 cm (1.5 inches).
The Garden Slug – 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.
The Keeled Slug – 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.
The Black Slug – 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.
Slug Lifecycle and Geographical Location
- 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.
Slugs can cause some real damage
- Look for irregular holes with smooth edges on leaves.
- Nearby will be evidence of their slime trials. They are particularly fond of succulent seedlings which, when left unprotected, can be totally destroyed in a single night.
- If your seeds do not seem to have germinated, it is possible that slugs have devoured the emerging seedlings underground.
Slugs love potatoes
Slugs will feast on your fruit and vegetable crop, including your:
- Brussel Sprouts
Slugs will also attack the leafy parts of plants, especially hardy ornamentals like Hostas
Slimy Slug Facts
- 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.
