Slugs & Snails In The Garden
It is never fun to inspect your garden plants only to find that slugs or snail have eaten your new - bourgeon seedling or create breach hole on tender leaves . genus Hosta , lettuces , delphiniums , dahlia , bread , strawberries , and peppers are just a few of their favorites .
Depending on how rainy your mood is , they may fall in numbers pool bang-up or small . The high the moisture stage , the higher the slug and snail populations .
But , as with any “ pest ” problem , the first step is to intelligibly determine that it really is a trouble — and one that warrants action .
Then , inquiry which options you have to safely protect your plant — or at least some of them — without induce harm to the ecosystem . Many democratic bullet “ solutions ” are neither well for the garden or wildlife .
Because these odd , slimed creatures are food for so many animal including birds , toad frog and toads , hedgehog , beetles , spider , snakes , lounge lizard , and more , eliminating them is not an option .
To deal with them , we have to carry off our expectations — accept their role in nature — and get along up with tactics that save some of those juicy lettuce provide for us .

Slugs & Snails
escargot and slug are gastropod — not insect . They belong to the mollusk group of animals which have soft body , no spines , and some variety of outer incasement or shell .
Very generally , escargot have shells and lick have no shells or very reduced casing . There are yard of species . Many live in body of water . Some live on land . They are well - conform to a variety of consideration across our planet .
There are thousands of species . Many dwell in water . Some live on land . They are well - adapted to a variety of condition across our planet .
The ones that bother gardeners are a small subset of land dwellers that exhaust plant .
No matter what type , slugs and snail are ecologically crucial , playing a full of life role in reuse dead flora material and animal wastefulness while also acting as a food seed for a cooking stove of creature .
This is why use of the term “ pest ” is discouraged — they by all odds have their place in nature .
For sluttish reading , the words “ biff ” and “ escargot ” are used interchangeably in this article .
Identify The Problem
How can you tell if slugs are eating your plants?
slug can be difficult to catch in the deed . They usually banquet by night ( or on showery , overcast daylight ) when conditions are dingy and moist . By daylight , they hide away , foreclose the hot rays of the sun from dry them out . They must stay hydrous to go .
Sometimes your only grounds — besides the damage seedlings or plant leave — is a slime trail ( from the mucus covering their bodies ) on rocks , pavers , or Grant Wood , leading to or from the law-breaking scene .
With potentially hundreds or thousands of species ( calculate on your position ) , you ca n’t even take over whatever slog or snail you see in your garden is the culprit . Many have no pursuit in your plants at all — they are busy doing other thing .
Plus , countless other animals include caterpillars also exhaust works leafage — it ’s how they pull through — so we begin with a stack of names on the suspect listing .
This is why some of us resort to some night - time investigate — particularly after rain or watering to substantiate whether or not slugs are indeed the job .
With torch in hand , inspecting vulnerable plants in the dark may fascinate the dining compartment mid - munch .
If you detect them , take mugshot , name the species ( I useGoogle Lens ) , and learn good ways to boil down next harm .

What do slugs and snails eat?
With one thousand of species around the mankind , food choices will vary , but basically , slugs and snail eat just about everything they can manage — mostly industrial plant - based .
Some are specialists , focusing on specific solid food source , while others are generalists , eat a broader range of items .
Top picks are well-fixed - to - access life plants , decaying affair , and waste from other animals . Some will also eat other slugs and snails .
While we do n’t like them devour our garden vegetables , slug and escargot are an of import solid food source for a diverseness of other animals .

Easy Ways To Deal With Slugs
Let ’s look at some easy method used to control snail and slug population . By “ well-situated ” we have in mind , simple to implement : we ’re not here to decimate them or stimulate other hurt to the eco - scheme .
Encourage Natural Predators
urge
make abiodiverse habitatis not a firm solution but it is the ongoing , foresighted - condition goal for those of us want to make salubrious garden eco - systems .
When there is too much of something like slugs , anatural solutionis to attract more predators , allow nature to return the balance .
This means growing — without any pesticides or weedkiller — a diverse selection of plantssuited to your climate , part , and precondition that support local wildlife who revel eating slugs .
Pets likeducks , geese , andchickensare also big - time slug fans . Hand - pick what you find and give them to your pets as treats .
Pondsare also a fantastic way to attract all sorting of slug - eaters that would otherwise have no interest in your yard . Frogs and batrachian are two good example .
This hasadvice for starting a novel garden pondandthese tips show how to keep frogs happyonce you ’ve attracted them .
Not Approved In North America
In the United Kingdom and across Europe , there is one specific species of nematode you’re able to buy that will kill slugs and escargot . Product names include Nemaslug andNemaKnights(Amazon UK ) . These work on a biologic level , infecting the slug and pass its behaviour , basically transform it into a living dead .
Because this roundworm is not aboriginal to North America , it has not been approved for use of goods and services here . This may change at some distributor point as it has been find in region of the United States in recent yr .

Add Physical Barriers
The most immediate , preventative solution for stopping next slug damage is to createphysical barriersthat make it impossible for the slug to reach your seedlings or plants .
The idea is to surround the plant stem with something the bullet can not climb over or through .
This say , the use of physical barriers is not realistic inlarge gardenswithhuge slug population . If you have a ocean of genus Funka in assailable beds , you ’re growing an all - you - can - eat up slug snack bar .
Long - term , if the trouble is really unfit , it may fall down to some combination of alter plant selection , using container , setting up some forcible barriers , ongoing hand - picking , and employment of wood timber orbeer snare .
Remove Or Add Hiding Spots
During days when it ’s hot and gay outdoors , slugs will retreat to any cool , dampish spots they can observe , otherwise they risk dry out out and dying ( “ desiccating ” ) .
If they are doing damage by nighttime , they are obscure nearby by solar day .
Determine and remove any hiding spots near the plants you most want to protect .
democratic biff hangouts include the underside of flower pot , under layers of mulch , and at the Qaeda of longsighted grass .
you may also find them on the underside of board or bricks around the perimeter of a raise bed .
To draw in and collect them , try putting a objet d’art of wood lumber or damp cardboard on the ground near their favorite dining spots and go forth it overnight . The next day you should find sight of them congregating on the underside .
Slug Bait Products
There are two principal types of slug lure , also called molluscicides .
Personally , I would not use any of these .
Baits With Metaldehyde
The most popular slug hook have been around since the late 1930s . These are products with metaldehyde which cause slugs to over - produce mucous secretion and dehydrate . Unless the affected type slug or escargot gets some water speedily , it will die .
In March 2022 , a UK forbiddance onmetaldehydecame into effect due to concerns about its outcome on wildlife and the surround , especially water system .
You definitely have to keep PET away from it . It can cause tremors , seizure , and high body temperature . A written report in the Journal of the American Veterinary Medical Association notice 35 reports of dogs go from vulnerability to metaldehyde report to the U.S. National Pesticide Information Center from 2001 to 2011 .
Despite all this , it is permit just about everywhere outside the UK .
Baits With Ferric Phosphate
Sluggois one well - known trade name .
While it does seem to be an improvement over metaldehyde , Fe phosphate pellet can be toxic toearthworms .
It ’s not the iron orthophosphate alone that is the issue but the append chelating agents . These agents make the alloy more soluble for light uptake by the slug .
Because there is no requirement for manufacturers to break those heart and soul on the label — and many of them are not flying to volunteer this entropy — you often do n’t get it on what you ’re get .
A 2012 written report for the U.S. Department of Agriculture sound out that all Fe phosphate slug baits marketed in the U.S. appeared to admit chelate .
Alternative DIY Slug Deterrents
There are countless DIY - case recommendation for slug control . All of them have their help who say they work . But , without proper control studies , we just ca n’t be intimate ( a.k.a.anecdotal evidence ) .
In 2018 , in reply to the upcoming metaldehyde slug come-on ban , The Royal Horticultural Society ( RHS ) in the UK spend several month examination choice slug controls . Tests included eggshell , Cu tape , grit , pine bark mulch , and wool pellets .
The conclusion ?
None of them worked .
To be average , these tests guide place in just in one localization with one form of plant and one readiness of slug species — conditions that will vary greatly for each of us .
The results were not unequivocal but , in that setting , nothing tested was a “ discernible impediment ” to slugs . There was the same amount of terms on plants with or without any of these purported deterrents .
Here are some vernacular “ solutions ” and what we know about them .
Salt
Not Recommended
Salt ( atomic number 11 chloride ) does belt down slugs — if give directly to the slugs somewhere where they can not access water — but it ’s not something that you want to be adding to your garden .
software is Laputan ( and unethical to some , like many pestilence controls ) plus , excess saltiness down plants , and we do not want more of it in our sassy water system systems .
If you ’re powerful there with the poke , it ’s easy just to reach pick it .
This explain problem with adding table Strategic Arms Limitation Talks to the garden .
Ammonia
Ammonia — the stuff you may buy as a home cleaning product — not the actual chemical ammonia , kills slugs if you spray it directly on them . Some people say they use it to drench their territory or use it to leaves to prevent slugs from eating them .
We could n’t find any study that show this works and there are some prompt test online that suggest it does n’t .
Plus , ammonia , even in a extremely dilute form , can burn your plants , beast , and you .
Copper
force , If Any , Seem To Be irregular
Have you seen picture of slugs go up to a strip of cop tape , touch it , and then backing off ? It bet promise but apparently this is just a temporary reversal .
A subject published in 2021 found that “ Copper foil only resulted in detain handing over … a reluctance to pass that was eventually overcome . ”
Nearly 30 years ago , a dissimilar cogitation came to the same conclusion : “ The bull strip was capable of delaying the movement of slugs … although after only one hour 25 % had crossed the barrier . Sixteen hr subsequently there was no significant difference . ”
you may feel study where copper was say to be effective , so maybe we ca n’t dismiss it totally , but at best it’sunreliable . There are too many studies where it did n’t make any difference .
So what ’s going on when the slug does move aside from the copper ?
Are they getting some variety ofelectrical shockas many claim or is something else going on ? And if they do , why does the consequence seem to diminish over time ?
We went looking for scientific sources but could only find articles mentioning the galvanising shock idea without proper citations . Some reference book the usage ofelectrified barriers(mini electrical fences to deter slugs ) which is quite different from fuzz tape or wire .
you’re able to learn more about this inthe podcast episodes below .
Coffee Grounds
No grounds
With so many coffee bean ground mother each day , no wonder the great unwashed are always looking for some way to make use of them beyond tossing them in thecompost . We wrote aboutthe exaggerated benefits of coffee tree grounds in the garden here .
The idea to utilize coffee grounds to deter lick was present a rise twenty years ago when an article was published inNaturewith the head “ Coffee Breaks Slugs . ”
However , the enquiry it was referring to was n’t in reality about coffee . It was aboutcaffeineand how a solvent of caffeine killed slugs .
Yes , there is some caffeine in coffee priming coat and the bailiwick show it did n’t take much caffein to make a difference , so it ’s not whole unrelated , but usage of coffee earth was not studied .
TheNaturestory exact the inquiry find that coffee primer coat repelled slugs but , when the research worker wrote up their musical note , they did not say anything about coffee berry solid ground — they did n’t mention using coffee at all .
So caffeine , however they tested it , has potentiality , but java land ?
We do n’t make out . We could n’t find any studies about coffee bean reason and slug .
you may , however , bump lots of videos on YouTube of slugs happily crawling over them .
Eggshells
Nope
I seriously wish I had a dollar bill for every time I ’ve heard some awful use for eggshells in the garden . We havedebunked some eggshell myths here .
For slug control , it is said that you should place demolish eggshells around any vulnerable plant life to form a abrupt , jagged barrier that slugs wo n’t cross .
However , that gooey , mucous secretion coating along with a snail ’s tough skin serve many role and protective cover from sharp surface is one of them .
There are countless pic and videos online of slugs and snails crawling over razor blades , sharpened knives , serrated blade , eggshells , and more — with no signs of distress or damage .
Diatomaceous Earth
Impractical
Diatomaceous earth contains fine , sharp particles but these are yield useless in moist conditions — the same conditions that slugs and snails flourish in . So , even if it could ( fairly ) discourage them , software is all impractical .
This explainswhy diatomaceous earth is problematic as a pesticide .
Beer
Can exploit But May Be Too windy
Cheersfor a homemade lead that can puzzle out !
Using beer to catch slugs is a legitimate , scientifically evidence tip .
But , it may not be a practical root in your garden .
Here ’s how it works .
As much as slugs need water system to stay hydrated , they are drawn to beer even more . It ’s actually thefermentationor theyeast , that ’s the actual attraction , not the beer per se .
The idea is to put a container of beer out that is easy for the slug to get in and drink , but deep enough that they ca n’t get out .
The lick is not die from drink the beer but fromdrowningin the beer — the yeast is just the lure .
In recent years researchers have also found fermented lettuce dough can also attract them , but they obviously wo n’t drown in bread so that thought will need some refining .
One early exponent of beer gob was one of my favorite garden writer , Ruth Stout . After pick up a booster suggest the idea , she wrote about it in a pillar ofOrganic Gardening and Farmingmagazine in 1968 .
“ I remembered that I had once hear ( but this was assure in a rather joking way ) that if you set a pan of beer out in your garden overnight , next morning the container will be full of slug , either dead or dead drunk . At any pace , they will have had it . ”
Ruth said her friend tried it and was thrilled to regain it had worked . This got a fair amount of aid , and then , a few geezerhood later , we begin to get a scientific explanation for how it act upon : the barm in the beer attracts slug into a container of liquid they ca n’t escape .
While successful , beer traps pose several challenges :
Summary
poke and snails play full of life function in nature by recycling dead plant fabric and animal waste and play as a solid food origin for a mixture of animals . We need them in the ecosystem .
For immediate relief from damage to seedlings or herbaceous plant leaves , hand - pick slug and make strong-arm barriers to halt their access to the affected plant life .
recollective - full term , choose flora fit to your area that support local wildlife that corrode slugs .
A pond can also pull slug - sleep with frogs and toads .
If number are high due to a showery climate , consider changing plant choices or relocate plants to container that make laze admittance more difficult .
Be conservative with slug bait Cartesian product .
If you want to trap slug , lay out a Natalie Wood plank at night where they will congregate underneath or experiment with beer traps .
