The best Slug pellets, compared.
Top pick: FERRIS Slug & Snail Killer Pellets 800 g Best value: Pestshield 4 × Slug & Snail Killer 300 g – About £0.91 per 100 g of the claimed 4 × 300 g fill at about £10.93, with 4.3 from 586 reviews. Half-full reviews limit that figure. Updated October 2026.
Slug pellets are a ferric phosphate bait you scatter on moist soil so slugs and snails stop feeding. UK gardeners use them on hostas, seedlings, lettuce and allotment beds. They are not a wool or seaweed barrier, and they are not nematodes you water into the soil. You recognise a suitable tub by a named active substance, a printed gram rate, and a pack that arrives closed. Metaldehyde products became illegal to sell and use in Great Britain from 1 April 2022, so an old tub belongs with local-authority waste. Ferric phosphate is the remaining amateur active substance. It often carries an organic-growing claim, and it usually leaves no corpses on the path. It is still a pesticide. The label rate binds you. Dogs can get stomach upset if they eat enough. Wildlife guidance, including from the RHS, is against pellets, including ones sold for organic growing. How to read the active substance and the skip rules is in the [slug pellets buying guide](/hub/pest-control/slug-pellets/sub/slug-pellets-buying-guide).

Question 1 of 2
Where are you using them?
The FERRIS 800 g tub is about £11.99 and shows 4.5 from 1,217 reviews, a higher star line than Provanto, but that count is shared with the two-pack. The bullets name ferric phosphate and also a nematode infusion, and nothing else on the listing shows a watered-in nematode pack, so that second claim is a listing conflict. Scatter is given as 5 g per square metre on bare ground, flower beds, vegetable patches and greenhouses. Organic-gardening wording appears without a named certifier, and rain resistance is not stated. The package line is 870 g against an 800 g title, which is a mismatch to check on the tub you receive. At about £1.50 per 100 g of the title fill it is dearer than Sluggo and Provanto without a larger independent review sample. Blue dye helps you see a scatter. It does not make the nematode sentence a biological control.
Pros
Cons
Best for: You want a stated 5 g rate and a greenhouse line, and you will ignore the nematode bullet.
Less suitable: You want nematodes, a certifier named on the page, or a star line that is not shared with another ASIN.
Specifications
Common questions
Do these pellets contain nematodes?
The bullets say both ferric phosphate and a nematode infusion. Nothing else on the listing shows a watered-in nematode pack. Treat the nematode line as a listing conflict.
Can you use them in a greenhouse?
The listing says bare ground, flower beds, vegetable patches and greenhouses, at 5 g per square metre.
Are the 1,217 reviews only for this tub?
No. The same star line and opening review titles appear on the two-pack ASIN B0DTTRF4VG.
This is the FERRIS two-pack at about £18.99, the dearest row in the basket, with a unit count of 2 and an item weight of 1.76 kg while the title still says 800 g. It carries the same 4.5 from 1,217 reviews as the single tub, so you are not paying for a second test. The bullets repeat ferric phosphate, the nematode infusion and 5 g per square metre for beds and greenhouses. At about £1.19 per 100 g of two 800 g fills it is cheaper per gram than the single FERRIS tub and still dearer than Provanto or a full Pestshield multipack. The nematode sentence is still unverified dry bait, not a substitute for a product you water into the soil. Rain resistance is not stated. Buy both tubs only if you already accept that conflict and you will use the fill. A higher star does not outrank the larger Provanto sample.
Pros
Cons
Best for: You have already decided the FERRIS single is acceptable and you want a spare tub in the same order.
Less suitable: You are paying the premium because 4.5 looks stronger than 4.4, or you think the pack contains nematodes.
Specifications
Common questions
What is in the pack?
The title says 800 g and 2 pack. The unit count is 2 and the item weight is 1.76 kg.
Where does the listing say to use it?
Bare ground, flower beds, vegetable patches and greenhouses, at 5 g per square metre.
The Provanto 800 g tub is ferric phosphate bait at about £7.32 in the 19 October 2026 amazon.co.uk scrape, with an OF&G organic-growing claim and a rain-resistant line for vegetables, flowers and ornamentals. Across 6,699 reviews the line is 4.4, shared with the two-pack, so that figure is one pool rather than two tests, and it is still the largest sample in this set. Reviewers describe plant damage stopping without bodies left on the path, which is what this bait is supposed to do. The bullets do not print a gram rate. A listing coverage claim of up to 210 square metres from 800 g works out at about 3.8 g per square metre, and that arithmetic is not Sluggo’s 5 g instruction. A 21 October 2026 check found no featured offer, so about £7.32 may not be the price you can check out. Reviews still mention watching dogs around the blue pellets, and a pet-friendly bullet is a claim, not a clearance from a poison service. It is the top pick here because of the review volume and a named active substance in one closable tub, not because it is a harmless product.
Pros
Cons
Best for: You want one closable ferric phosphate tub with a large UK review sample and you will read the carton for the gram rate.
Less suitable: You need 5 g per square metre printed on the Amazon bullets, a price you can check out today, or a product a poison line has cleared for dogs.
Specifications
Common questions
Can you use these pellets on vegetables?
The listing says vegetables, flowers and ornamental plants, and it claims OF&G registration when used as directed.
Does the listing say they are safe around dogs?
The bullets say safe around dogs, pets and wildlife when applied as directed. That is the listing claim. Reviews still mention watching dogs around the pellets.
Will you see dead slugs the next morning?
Reviews on this listing describe plant damage stopping without bodies left on the surface.
This Provanto listing is the pack of two at about £14.64, with an item weight of 1.6 kg and the same model number, 86601082, as the 800 g tub. The title still says 800 g, and the bullets say the text applies to each unit, so you are buying two fills of the same bait rather than a stronger formula. The star line is the same 4.4 from 6,699 reviews, which means the two-pack does not add a second body of evidence. At about £0.92 per 100 g of the listed 1.6 kg it matches the single tub in this scrape, so the extra pack is storage, not a discount. This listing adds a rainfast claim of up to 10 days and names flowers, fruits, herbs and vegetables. That day-count is a listing claim, not a measurement after a British downpour. You still do not get a printed gram rate, and about £14.64 only helps if you will use both tubs before a lid is left off in a damp shed.
Pros
Cons
Best for: You already want Provanto and you would rather keep a second unopened tub than reorder mid-season.
Less suitable: You are hoping the two-pack is a discount, or you want reviews that apply only to this multipack.
Specifications
Common questions
Is this two tubs or one 800 g tub?
The size field says pack of 2 and the item weight is 1.6 kg. The title still says 800 g, and the bullets say the text applies to each unit.
How long does this listing say the pellets resist rain?
This listing says rainfast for up to 10 days. That is a listing claim, not a measured result.
Are the 6,699 reviews only for this pack?
No. The star line and the opening review titles match the 800 g ASIN B09RQQT8GY.
Neudorff Sluggo is an 800 g tub of blue hydrated ferric phosphate pellets at about £7.99, with 4.3 from 4,830 amazon.co.uk reviews on this ASIN rather than a shared pool. The bullets tell you to scatter 5 g per square metre in the late evening or early morning, and they say there is no wait until harvest on vegetables and fruit. The title also says the tub is for 100 square metres, which does not match 5 g per square metre on 800 g, because that rate covers 160 square metres, so the gram line is the one to follow. The listing says you should not expect slime traces or visible dead slugs. One review reports mould and dead pot plants after heavy rain. That is a single report, not a new dose. Organic-systems wording is on the bullets without a named certifier, unlike Provanto’s OF&G line. At about £1 per 100 g it costs a little more than the top pick, and it is the tub to open when you want 5 g per square metre written on the Amazon page.
Pros
Cons
Best for: You want the gram rate on the listing before you scatter, on vegetables or fruit, and you will ignore the 100 square metre title line.
Less suitable: You want the cheapest 100 g, an OF&G name on the bullets, or a bait you can judge by corpses the next morning.
Specifications
Common questions
How much does the listing tell you to scatter?
The bullets say 5 g per square metre in the late evening or early morning. The title also says for 100 square metres, which does not match 5 g per square metre on 800 g.
Can you eat the crop afterwards?
The listing says there is no wait until harvest on edible and non-edible plants, and to use it on vegetables and fruit.
Does the listing expect visible dead slugs?
The bullets say there are no slime traces and no visible dead slugs.
Pestshield sells four 300 g tubs of mini blue ferric phosphate pellets at about £10.93, with 4.3 from 586 reviews on this ASIN. On the claimed 1.2 kg that is about £0.91 per 100 g, the lowest figure in the set, which is why it is the best value here. The item-weight field says 1.44 kg, and the bullets do not print a gram rate or name edible crops. Organic wording appears without a certifier. More than one review says the tubs arrived about half empty, with the pellets several centimetres below the lid, so the price per 100 g only holds if the tubs are actually full. In the scrape the rank sat at 83 in Slug & Snail Control, far below Provanto. Four small tubs can suit a shed where you want a spare lid. They are a poor bargain if you count 1.2 kg and find half of it missing.
Pros
Cons
Best for: You want the lowest price per claimed 100 g and you will check that each tub is full before you rely on the weight.
Less suitable: Half-empty packs are the complaint you most want to avoid, or you need a printed scatter rate.
Specifications
Common questions
How many tubs are in the pack?
The title says 4 × 300 g. The item weight is 1.44 kg. Reviews say the four tubs arrived, and some looked about half full.
What active substance is on the listing?
The bullets say ferric phosphate and mini blue pellets.
Did reviewers find the tubs full?
More than one review says the tubs were about half empty, with the pellets several centimetres below the lid.
Neudorff Sluggo Ultra+ is a 650 g bottle at about £8.50 with 4.3 from 167 reviews, a much smaller sample than the Sluggo 800 g tub. The Amazon listing does not name an active substance or a gram rate, the only bullet on the listing is Natural, and the organic word sits on the title. Neudorff’s own Ultra+ page states 20 g/kg and 2.5 g per square metre, a different instruction from Sluggo’s 5 g, and that rate is not printed on this ASIN. Do not copy the 800 g tub’s dose onto this bottle. Reviewers report birds, especially crows, eating the pellets unless the crop is covered, and one buyer hoped they were friendly to hedgehogs. At about £1.31 per 100 g of the 650 g fill it looks dear until you use the manufacturer’s lower rate, which you cannot read on the page you are buying from. The listed weight is 671 g, and this is a bottle for someone who will read the carton in the hand.
Pros
Cons
Best for: You already know Ultra+ from the carton and you will dose from that label, not from the Sluggo 800 g bullets.
Less suitable: You need the active substance and the gram rate on the Amazon page, or birds are clearing bait from an open bed.
Specifications
Common questions
Does this Amazon listing state the active substance?
No. The title is Neudorff Sluggo Ultra+ pellets and the only bullet is Natural.
What do the reviews say about wildlife?
Reviewers report birds, especially crows, eating the pellets unless the crop is covered, and one buyer hoped they were hedgehog friendly.
Growing Success Advanced is 575 g, including 15% extra, at about £7.49, with ferric phosphate named, a claim of certification for organic use that does not name the certifier, and an amazon.co.uk line of 4.2 from 122 reviews. The bullets cover plants, seedlings and crops, say crops can be eaten shortly after application, and say the bait stays effective after rain, watering and sunlight. The manufacturer page states 5 g per square metre, and that figure is not on this Amazon listing. Which? has reported results from ferric phosphate and named this product in that account. That is their trial, not a laboratory test for this page, and it does not place this tub above the larger review samples. The complaints that dominate the reviews are lids off in transit, crushed cardboard and pellets spilled into the delivery bag, and the title says granules while the bullets say pellets. At about £1.30 per 100 g it is an inexpensive named bait when the tub arrives closed.
Pros
Cons
Best for: You want a small named ferric phosphate pack for seedlings and you will reject a tub that arrives open.
Less suitable: You are ordering for the whole allotment and a spilled bag would waste the dose, or you need the gram rate on the listing.
Specifications
Common questions
Can you use it on seedlings and crops?
The bullets say plants, seedlings and crops, certified for organic use, and that crops can be eaten shortly after application.
What do reviewers complain about?
Lids off in transit, cardboard tubs crushed, and pellets spilled into the delivery bag. The slug control itself is praised when the contents arrive.
JKG’s 800 g listing is about £8.95 with 3.9 from 29 reviews and only eight review texts on the listing, the thinnest and lowest star line here. Amazon’s item form is powder, the bullets also say rain-resistant pellets, and the listing does not state an active substance, so this is not a confirmed ferric phosphate bait. A coverage line of up to 100 square metres has no gram rate beside it, and the organic-based wording appears without a certifier. One review says the advert suggested indoor use while the pack said to keep it away from children and pets, yet the bullets describe outdoor beds and paths. The package weight is 870 g against an 800 g title, and the dimensions match the FERRIS single’s box size, which is another reason to read the label before you scatter anything. At about £1.12 per 100 g the price is not the problem. The missing active substance is. Skip it when you need a named ferric phosphate pellet.
Pros
Cons
Best for: You already hold the physical pack and the label names ferric phosphate at a rate you can follow.
Less suitable: You are choosing from the Amazon page alone and need a named active substance before you buy.
Specifications
Common questions
What is the active substance?
The listing does not state one. Amazon’s item form is powder, while the bullets say rain-resistant pellets.
Can you use it indoors?
One review says the advert suggested indoor use and the pack said keep it away from children and pets. The bullets describe outdoor beds and paths.
Nine amazon.co.uk slug and snail listings were compared from a 19 October 2026 scrape. The number on each card is the star rating times 20, so 4.5 is 90 and 4.4 is 88. Shared review pools are counted once when a badge is chosen. They are not a second penalty inside that number. There is no laboratory trial. The weights below are how the top pick and the best value were chosen when a higher star line was set aside. The top pick is the Provanto 800 g tub: ferric phosphate named, one tub, 4.4 from 6,699 reviews. FERRIS scores 90 and does not take that badge, because the pool is shared, the sample is smaller, and a nematode bullet conflicts with dry bait. Best value is Pestshield 4 × 300 g at about £10.93, about £0.91 per 100 g of the claimed fill, with 4.3 from 586 reviews. Half-full reviews limit that badge. It is not a safety ranking. A 21 October 2026 check found no featured offer on Provanto 800 g.
Review sample
30%The card number is the amazon.co.uk star rating times 20. A shared pool, such as Provanto’s 6,699 or FERRIS’s 1,217, counts once when the badge is chosen. A larger independent sample outranks a higher star on a smaller shared pool.
Named active substance
25%Expect ferric phosphate on the listing. If the page will not name the active, another brand’s safety line is not borrowed. A nematode sentence on dry pellets is a listing conflict, not a second active.
Gram rate on the listing
20%A printed gram rate for that tub outranks a coverage slogan. Sluggo prints 5 g per square metre. Ultra+ is a different rate, and it is not on the Amazon listing. Rates are not swapped between brands.
Listing consistency
15%Points come off for a title that disagrees with the pack count, a powder item form beside a pellet bullet, a missing certifier on an organic line, and reviews that describe half-empty tubs or lids off in transit.
Price per 100 g
10%Best value is the lowest price per 100 g of the claimed fill, not the cheapest tub and not a safety score. The figure only holds if the tubs arrive full.
Start with the active substance, then the gram rate, then whether the tub arrives closed. Slug pellets here are ferric phosphate bait, not a barrier and not a nematode. Shelf prices in the 19 October 2026 scrape run from about £7.32 to about £18.99. The top pick is a single Provanto tub. The best value is the Pestshield multipack if the tubs are full. Nothing on this page is a laboratory trial.
Slug pellets in this comparison are ferric phosphate bait you scatter on moist soil so slugs and snails stop feeding. UK gardeners use them on hostas, seedlings, lettuce and allotment beds. They are not a wool or seaweed barrier, and they are not nematodes you water into the soil. Metaldehyde products became illegal to sell and use in Great Britain from 1 April 2022, after supply ended on 31 March 2021 and use was allowed until 31 March 2022.
Wool, seaweed and other barriers are a different product. A slug pellet in this set is ferric phosphate bait you scatter. Nematodes are watered in. A dry pellet that claims a nematode infusion is a listing conflict.
Ferric phosphate usually leaves no bodies on the path. Sluggo’s bullets say there are no slime traces and no visible dead slugs. Judge new leaf damage after several days, not a clear path the next morning.
Sluggo’s bullets say 5 g per square metre. Ultra+ is a lower rate on the manufacturer page, and that rate is not on the Amazon listing. Do not use 5 g per square metre on Ultra+, and do not treat a coverage slogan as the dose.
Expect ferric phosphate. If the listing will not name it, do not borrow another brand’s line. JKG is in that gap, and Amazon’s item form says powder. Sluggo’s bullets print 5 g per square metre. The title also says 100 square metres, which does not match 5 g per square metre on 800 g, because that rate covers 160 square metres, so the gram line is the one to follow.
Growing Success reviews centre on lids and crushed cardboard. Pestshield reviews mention half-empty tubs, so about £0.91 per 100 g only holds if the four tubs are full. A two-pack that shares the single tub’s reviews is not a second proof. Provanto’s 6,699 reviews are one pool with the two-pack. FERRIS’s 1,217 reviews are one pool with its two-pack. OF&G means an inputs claim. It does not cancel the label rate, and it does not answer the EDTA question Which? raises.
Three typical situations, each with a recommendation from this comparison.
You want one closable tub and a straight answer on dogs. Provanto Slug & Snail Killer Max 800 g is about £7.32 in the 19 October 2026 scrape, with ferric phosphate named, an OF&G claim, and 4.4 from 6,699 reviews shared with the two-pack. The bullets do not print a gram rate, and a later check found no featured offer. A pet-friendly line is a listing claim. Skip it if you need 5 g per square metre on the Amazon page.
You need a gram rate before you scatter, and a plan for birds. Neudorff Sluggo Slug & Snail Killer 800 g is about £7.99, with 5 g per square metre on the bullets and 4.3 from 4,830 reviews on this ASIN. The title’s 100 square metre line does not match that rate on 800 g. Ignore the title coverage and follow the gram line. Skip it if you want the cheapest 100 g.
You are counting four tubs and you will check the fill before you rely on the weight. Pestshield 4 × 300 g is about £10.93, about £0.91 per 100 g of the claimed fill, with 4.3 from 586 reviews. More than one review says the tubs arrived about half empty. The bullets do not print a gram rate. Skip it if a short fill is the complaint you most want to avoid.
The top pick is Provanto Slug & Snail Killer Max 800 g at about £7.32. Ferric phosphate is named, it is one tub, and the line is 4.4 from 6,699 reviews, the largest sample here, shared with the two-pack. FERRIS scores 90 because 4.5 times 20 is 90, and it does not take the badge: the pool is shared, the sample is smaller, and the bullets claim a nematode infusion the listing does not support. A 21 October 2026 check found no featured offer on the Provanto 800 g, so about £7.32 may not be the price you can check out. The best value is Pestshield 4 × 300 g at about £10.93, about £0.91 per 100 g of the claimed fill, with 4.3 from 586 reviews. Half-full reviews are the limit on that badge. It is not a safety ranking. None of these scores is a laboratory trial.
Pestshield 4 × Slug & Snail Killer 300 g
About £0.91 per 100 g of the claimed 4 × 300 g fill at about £10.93, with 4.3 from 586 reviews. Half-full reviews limit that figure.
