Is Having Slugs and Snails In Your Garden Good or Bad?
Make a donation. Slugs are widespread animals which can cause problems in the garden, eating holes in leaves, stems, flowers, tubers and bulbs. They can cause damage throughout the year on a wide range of plants, but seedlings and new growth on herbaceous plants in spring are most at risk. Slugs are gastropods; single-shelled, soft-bodied animals in the mollusc group of animals. Slugs can use their rasping tongues to make holes in leaves, stems, buds, flowers, roots, corms, bulbs and tubers of many plants.
There are many control options available for slugs and snail but despite this they remain a persistent pest. The RHS is carrying out a scheme of research on gastropod control methods to improve the advice we can give to home gardeners. Most slugs feed at night , and the slime trails , if present, can alert you to the level of activity. Damage is usually most severe during warm humid periods. Slugs can make a meal of a wide range of vegetables and ornamental plants, especially seedlings and other soft growth.
Hostas , delphiniums , dahlias , gerberas , sweet peas and tulips are regularly attacked by slugs, and it can be difficult to grow these plants if you have a big slug problem.
In the vegetable garden peas , beans , lettuce , celery and potato tubers are often damaged. Many larger slugs primarily feed on decomposing organic matter such as dead leaves dung and even dead slugs. In the compost heap they can be a valuable part of the composting process. Slugs are so abundant in gardens that some damage has to be tolerated. They cannot be eradicated so targeting control measures to protect particularly vulnerable plants, such as seedlings and soft young shoots on herbaceous plants will give the best results.
A biological control 'Nemaslug' specific to molluscs, with no adverse effect on other types of animal, is available in the form of a microscopic nematode or eelworm that is watered into the soil. The nematodes Phasmarhabditis hermaphrodita enter slugs' bodies and infect them with bacteria that cause a fatal disease. Best results are achieved by applying in the evening to moist but well-drained soils; control may be less successful in heavy soils, such as clay.
The nematode is available from refrigerated cabinets in some garden centres or by mail order from suppliers of biological controls download pdf below. There are many preventive measures that have been used by gardeners to minimise slug damage. Most of these do not have any scientific evidence to prove that they are effective. These measures include:. Most of these non-chemical control options have very little scientific research into them, but the RHS is hoping to address this knowledge gap and is carrying out a range of scientific studies.
The slugs that damage potatoes spend much of their time in the soil where they do not come into contact with slug pellets. The nematode treatment see above can be effective.Damage usually begins during August and becomes progressively worse the longer the crop is left in the ground.
Early potatoes usually escape damage; maincrop potatoes should be lifted as soon as the tubers have matured if the soil is known to be slug infested. Heavy applications of farmyard manure and other composts can encourage slugs, and so inorganic fertilizers should be used where slugs are a problem. Potatoes vary in their susceptibility to slugs. Damaged potatoes are more vulnerable to storage rots and the crop should be sorted into sound and damaged tubers, with the latter being stored separately for early consumption.
Following the manufactures instructions scatter slug pellets thinly around vulnerable plants, such as seedlings, vegetables and young shoots on herbaceous plants. It is important store pellets safely and scatter them thinly as they can harm other wildlife, pets and young children if eaten in quantity.
As of March there is only one type of slug pellet approved for use in gardens, those based the active ingredient ferric phosphate. This type of slug pellet is approved for use by organic growers. To protect children and pets pellets must be used and stored carefully, as directed on the packaging.
Metaldehyde ban In September the government announced the withdrawal of metaldehyde slug control, with product sales ending in March and remaining stocks to be used up or disposed of by 31 st MarchThe withdrawal was planned following advice from the UK expert committee on pesticides and the Health and Safety Executive HSE who consider that metaldehyde poses an unacceptable risk to birds and mammals.
An initial withdrawal in was overturned due to problems with incorrect implementation.Please be aware that these and other product names may be relaunched using ferric phosphate as the main ingredient instead, and check any products you have stored to make sure they are used up or disposed of safely by the end of MarchInclusion of a pesticide product does not indicate a recommendation or endorsement by the RHS.
It is a list of products currently available to the home gardener. Most plants, once established, will tolerate some slug damage and control measures can be discontinued. The RHS is researching sustainable control options for slugs and snails.

Slugs and snails, along with other animals including conches and limpets, are gastropods. A gastropod is a single shelled, soft-bodied animal in the mollusc group of animals.
The name gastropod comes from the Greek words gaster, meaning stomach, and poda , meaning feet. All gastropods have a muscular foot that they use to move around. Slugs have evolved to have a reduced shell that often cannot be seen from the outside. There are 44 species of slug in the UK, only some of which cause damage to plants. Many species feed on dead plant matter so some slugs of the slugs in the garden may actually be beneficial.
Slugs vary in size from the grey field slug Deroceras reticulatum , which is no more than 5cm about 2in long, to the large black slug Arion ater , which can be 12cm about 5in when fully extended. Some slugs vary in colour; Arion ater can be black, orange-brown or buff coloured. Most slugs feed in or on the soil surface, but keeled slugs Milax species live and feed mostly in the root zone. Slugs remain active throughout the year, unlike snails, which are dormant during autumn and winter. Warmer weather, combined with damp conditions greatly increases their activity.
Slugs are most active after dark or in wet weather.Reproduction occurs mainly in autumn and spring, when clusters of spherical, yellowish-white eggs can be found under logs, stones and pots. Despite the array of control measures available they are still considered persistent pests. To tackle this the RHS launched scheme of research inCurrent and recent work includes investigating:.

Slugs and snails seem to lie in wait for the unwary gardener. No sooner have the first tender young shoots emerged in spring or new bedding been planted, than the tell-tale signs of feasting slugs and snails are noticed: irregularly shaped holes in leaves and sparkling slime trails criss-crossing newly planted beds. Slugs and snails will attack any soft growth, with a particular liking for lush plants such as hostas. Slugs or snails? You can tell whether your problem is slugs or snails or both! Snails also tend to be a bit fussy about what they eat, often feasting on the softer tissues between ribs of a leaf, leaving tell-tale skeletonised remains. Slugs, on the other hand, tend to stay around ground level and simply eat everything within rasping distance. Keeled slugs actually live underground, eating roots and tubers.

With more people spending time in their gardens throughout the pandemic, the Royal Horticultural Society RHS saw an 88 percent increase in pest and disease enquiries last year.
Slugs are the number 1 problem for gardeners trying to grow hostas. The plants are a favorite food for slugs and snails and are a very common problem to deal with.
How To Get Rid of Slugs and Snails in the Garden
When slugs and snails feed on sodium ferric EDTA bait — even in small amounts — they immediately stop eating. The defeated pests slink back to hiding places, where they die in three to six days. Even if sluggish pests are seen, they're no longer doing damage. However, staying vigilant is a must. Slugs and snails hatch from eggs, so the next invasion may be waiting. Be mindful; remove plant debris and avoid overwatering.
Four easy ways to eliminate slugs
Snails and slugs are troublesome pests that can cause serious damage in the garden. They love cool, moist weather and feed at night or on rainy days, so they usually go unseen when they are doing their damage. They are commonly found hiding under upturned flower pots, dense groundcover plants and any debris in the garden. A study by Dr Dave Hodgson, associate professor of ecology at the University of Exeter in the UK revealed that the top speed of a snail is a sluggish one metre per hour but they will travel distances of up to 25 metres in a hour period, and seek out areas of shelter overnight. That is enough range to cover most backyards! Snails and slugs feed on a both living plants and decaying plant matter.
Snails and slugs feed on a both living plants and decaying plant matter. They cut holes in the middle of leaves, eat seedlings completely to the ground.
How to Get Rid of Slugs
Skip to content. Earwigs, slugs and snails require humid, damp habitats for shelter and reproduction.They hide during the day, and then come out to feed and scavenge at night.
By on. In the two previous posts I looked at ways to use Coffee Grounds in the Garden and the effect of coffee grounds on ants. There was one outstanding question that did not get resolved. Do coffee grounds deter slugs from eating your plants? Since I could not find any scientific work on this topic I decided to run some tests myself. Photo Source: All About Slugs.
For many gardeners, the slug and snail population seemed to explode last year, with many fraught and distressed gardeners asking for my advice on the best way to protect their plants from slugs and snails.
After all, snails are slimy, ugly, and destructive enough to harm your lawn and garden. As an experienced provider of pest management services , we understand how to help homeowners keep their properties clean, clear, and snail-free. If you have a snail problem, the first step is to figure out what caused it. Like any pest, snails are probably seeking two things when they appear on your property: food and shelter. Because of their slimy, moist bodies, snails thrive in environments that shelter them from the heat of the sun.
