The best wasp killers, compared.
Top pick: Zero In wasp nest powder triple Best value: Zero In wasp nest powder 300g – £5.50 puffer with 4.3 from 3,921 ratings, the largest review base here for a hidden entrance. Updated October 2026.
A wasp killer for a UK household is an amateur nest treatment, or a flying-insect aerosol for a wasp in a room. Powder goes on a hidden entrance: an air brick, cavity, soffit gap or ground hole. Foam goes on a papery comb you can see, if the jet reaches it. Quality is the match between the entrance and the pack, plus an amateur label with a named active. The [wasp killer buying guide](/hub/pest-control/wasp-killer/sub/wasp-killer-buying-guide) sets the order: name the job, read the label, then compare price. Treat at dusk or dawn with both feet on the ground. A high nest, a sting allergy, or a suspected yellow-legged hornet means you stop. The usual nest products are a permethrin dust in a puffer, applied at an entrance you can see, or a foaming aerosol aimed at a papery nest you can see.

Question 1 of 2
What can you see?
The Zero In AMZ910M triple pack was £11.99 on 16 October 2026, with 4.6 from 539 ratings, the highest star line in this set. It is the same class of permethrin entrance powder as ZER910, sold as a multi-pack for the home, sheds, garages and gardens, with a child-resistant cap. The title says a triple pack, while the unit-count field reads “1 1”, so three tubs are not a settled fact from the listing alone. In the first 50 UK reviews, several people used one bottle of the three, and a few needed another evening. One reviewer still saw activity after three tubs, which is the limit of a puffer when the powder never reaches the comb. The listing has no nest-count claim and no speed claim. You still have to get close to the entrance. It fits a second hole or a spare evening, and it is a poor buy if one £5.50 tub would cover a single small entrance.
Pros
Cons
Best for: More than one entrance, or a spare tub kept for a second evening on a hidden nest.
Less suitable: A single small nest if you only want the £5.50 tub, and any job that needs a long foam jet.
Specifications
Common questions
Is this a different powder from the single Zero In tub?
The listing also says permethrin nest powder in a puffer, for indoor and outdoor entrances, morning or evening. The title adds a triple pack. The unit-count field reads 1 1, so the pack count is not clean on the listing.
Does the listing give a speed?
No. A listing question asks if it kills wasps quickly. The spec block does not answer it.
What did reviewers say about how much they used?
In the first 50 UK reviews, several people used one bottle of the three. A few needed repeat applications, and one still saw activity after three tubs.
Raid’s duo pack was £8.70 on 16 October 2026, with 4.5 from 347 ratings, and it ranks in grocery insect sprays rather than Bee, Wasp & Hornet Control. The title says a fly, wasp and mosquito spray in a 2×300 ml pack. The bullets describe an indoor knockdown mist for insects in flight or for a room, not a nest. Most of the first 50 UK reviews are about flies and the smell of the mist. A few mention a wasp in the air, and none describe soaking a comb. The unit-count field says 1.0 millilitre and the volume field says 100 millilitres, so the pack size in the title and the spec block disagree. No active is named on the listing, and some addresses outside mainland UK are excluded from delivery. It is the can for flies or for one wasp in a room when there is no flight line into the wall, and it is the wrong product for an air brick, loft, hedge or cavity.
Pros
Cons
Best for: Flies or a wasp in a room when there is no nest to treat.
Less suitable: Any nest in a wall, loft, air brick or hedge.
Specifications
Common questions
Does this treat a wasp nest?
The listing does not say so. Bullets describe a spray for mosquitoes, flies and other flying insects, used on the insect or in a room. The title adds wasp.
Is the pack two 300 ml cans?
The title says 2×300 ml. The unit count says 1.0 millilitre and the item volume says 100 millilitres, so those fields disagree.
What did the UK reviews talk about?
Most of the first 50 reviews are indoor flies and the smell. A few mention a wasp in flight. They do not describe soaking a nest.
Nippon 5NWP300 is a 300 g permethrin dust at £7.99, with 4.4 from 1,265 amazon.co.uk ratings on 16 October 2026. The bullets tell you to dust the nest or leave piles at the entrance, indoors or outdoors, without stirring the colony. The public label, HSE 9219, is the clearest statutory box in this set: it names permethrin and it warns about bats, bees and fish tanks. That label is why it is the top pick here, just ahead of the cheaper Zero In tub, even though it costs £2.49 more and has fewer ratings. Reviews split between a hole that was quiet by morning and wasps still flying with powder on them. One review says the spout came off when the bottle was squeezed upside down. The Amazon volume field says 300 gallons, which does not match a 300 g tub, so ignore that figure. It suits an entrance you can dust at close range, including one a foam jet has already missed.
Pros
Cons
Best for: An entrance you can dust at close range, including after a foam can has missed a hidden nest.
Less suitable: Anyone who needs a jet from several metres, or a pack whose listing fields are tidy.
Specifications
Common questions
Does the listing say it works on hornets?
The listing asks that question. The spec block does not answer it. The bullets describe wasp nests and permethrin.
Is the 300 gallon line a real volume?
The Amazon attribute says 300 Gallons. The unit count and size say 300 g. Treat 300 g as the pack and ignore the gallon figure.
What went wrong in reviews?
Some of the first 50 UK reviews say wasps were still flying the next day, sometimes still coated in powder. One review says the spout came off when the bottle was squeezed upside down.
Zero In ZER910 is a 300 g permethrin puffer listed at £5.50 on amazon.co.uk on 16 October 2026, with 4.3 from 3,921 ratings. The listing points it at nest entrances, cracks and cavities, indoors or outdoors, in the early morning or late evening, and it claims up to five nests. In the first 50 UK reviews, people often describe a hidden hole going quiet after one puff, including holes where a foam can had already failed. You still have to stand close enough to puff the entrance, and dusk only reduces how many wasps are flying. A second evening comes up often enough that the five-nest line is a pack claim, not a result you can count on. The item-weight field says 220 g against a 300 g pack line, so the quantity on the page is not tidy. It is the best value in this set for an air brick, soffit gap or ground hole you can reach with both feet on the ground.
Pros
Cons
Best for: A wasp entrance in an air brick, soffit gap or cavity when you can treat from the ground at dusk.
Less suitable: A visible nest you want to soak from several metres, or a single wasp in the kitchen.
Specifications
Common questions
Does the listing say this powder is for indoors?
Yes. The bullets name roof spaces, wall cavities, sheds, garages, outbuildings and garden areas, and they say indoor and outdoor use.
What active does the listing name?
Permethrin. The bullets also say to read the label and that the cap is child-resistant.
How many nests does the pack claim?
The listing says a 300 g puffer can treat up to 5 wasp nests when used as directed. That is the pack claim, not a result from these reviews.
Zero In ZER556 is the only foam in this set: a 600 ml trigger can at £12.94, with 3.6 from 5,173 amazon.co.uk ratings, the lowest star line here. The listing claims a jet of up to 4 metres and treatment of 4 to 7 nests, late in the evening, indoors or outdoors, and the title includes hornets. The Amazon bullets do not name an active. The maker’s own page names tetramethrin and 1R-trans-phenothrin, which is a different source from the star line. Reviews agree it can knock down a papery nest the foam actually hits, in a shed, hedge or loft you can stand in. They often dispute the 4 metre figure, with reports of about 12 inches, 18 inches or 2 metres, especially if the can was not shaken. Several say it does nothing through an air brick, because the foam stops on the face of the brick. Only 39 review texts sit against 5,173 ratings, so buy it for a comb you can see, and only after a test squeeze reaches that comb.
Pros
Cons
Best for: A papery nest you can see, in a shed, hedge or loft you can stand in, if a test squeeze reaches it.
Less suitable: An air brick or cavity where the comb is out of sight.
Specifications
Common questions
Does this listing name the active?
Not in the captured bullets. They describe a foam jet, a 4 metre reach and 4 to 7 nests. They do not print an active substance. The maker’s page names tetramethrin and 1R-trans-phenothrin.
Can the listing be used on hornets?
The title and bullets say wasp and hornet nest killer foam. A pet question on the page is not answered in the spec block. A yellow-legged hornet nest is a report, not a shop-foam job.
Did reviewers get 4 metres?
Some of the 39 UK reviews describe a long jet. Others report about 12 inches, 18 inches, or 2 metres, often when the can was not shaken or pressure was low.
This is an editorial comparison of five amazon.co.uk listing extracts, not a laboratory efficacy or safety test. Prices, stars and review counts are the figures captured on 16 October 2026 and may change. The score is out of 100 before deductions for a pack field that contradicts the title, or for a main reach claim that UK reviews on that ASIN dispute. None of these scores is a safety ranking, and none of them says a nest dies overnight.
Fit for the stated job
25%Full credit needs a nest entrance or a visible comb, with powder or foam to match. A flying-insect aerosol keeps a low score because it is not a nest treatment.
Amazon rating
20%Up to 20 points from the amazon.co.uk star line divided by 5. Stars are not the same figure as the editorial score.
Listing clarity
20%A named active, a consistent pack, a stated timing and a usable applicator each add points. A published HSE number on the public label adds clarity. Conflicting pack fields do not.
Review volume
15%At least 5,000 ratings score 15, at least 3,000 score 13, at least 1,000 score 11, at least 500 score 8, at least 300 score 6, and a thinner count scores 4.
Value in this set
15%Up to 15 points from the shelf price against a nest job, not from price alone. The £5.50 puffer is the best value because the nest job and the review base are both there.
Review sentiment
5%Up to 5 points, reduced where the same complaint returns: a second evening, a short jet, or wasps still flying.
Name the job before you compare prices. A hidden entrance, a visible comb and a wasp in the room are three products, not one. Powder, foam and a knockdown spray are not substitutes. Then confirm an amateur label, and only then look at pack size, the listed reach and the GBP price. “Up to 5 nests” or “4 to 7 nests” is a maker claim, not a promise about your wall.
A wasp killer on this page is an amateur biocide for a nest, or a flying-insect aerosol that knocks down wasps in a room. The usual nest products are a permethrin dust in a puffer, applied at an entrance you can see, or a foaming aerosol aimed at a papery nest you can see. Hidden entrances — an air brick, a cavity, a soffit gap or a ground hole — are a powder job, because workers carry the dust in.
Foam stops on the face of the brick. Reviews on the Zero In can say it does nothing when the comb is out of sight. A hidden entrance is a powder job.
Workers need to carry dust in. Closing the entrance the same evening wastes the puff, and a second evening comes up often enough that the five-nest line is a pack claim.
A room aerosol knocks down insects in flight. It does not treat a nest. A yellow-legged hornet is a report via Asian Hornet Watch, not a shop tub. Do not dust in the rain, and do not treat a 4 metre claim as measured.
The first split is the job, not the star line. A hidden entrance — air brick, cavity, soffit gap or ground hole — needs powder. Workers carry the dust in, so you leave the hole open. A visible comb within the jet’s real reach needs foam. A wasp in the room, with no flight line into the wall, needs a knockdown spray. Those three are not substitutes. You also have to be able to treat at dusk or dawn with both feet on the ground.
Confirm amateur use and read the statutory box: HSE number, active, bees, water and bats. Do not buy a professional-only pack. Bendiocarb dust, Ficam D, is withdrawn, and BPCA says using or storing it is illegal. COPR guidance says the pack must state the actives and an HSE number, and must not claim to be non-toxic. In this set Nippon’s public label, HSE 9219, is the clearest box: permethrin, plus warnings on bats, bees and fish tanks.
Three typical situations, each with a recommendation from this comparison.
You can see a flight line into an air brick, soffit gap or ground hole, and you can treat at dusk with both feet on the ground. Nippon 5NWP300 is the top pick: permethrin, public label HSE 9219, £7.99, 4.4 from 1,265 ratings. You still stand close to the hole.
The job is the same hidden entrance, and you want the lowest nest-powder price in this set. Zero In ZER910 is £5.50 with 4.3 from 3,921 ratings. “Up to 5 nests” is a pack claim, and some reviews needed a second evening.
The papery nest is in a shed, hedge or loft you can stand in, and a test squeeze reaches it. Zero In ZER556 is the only foam here, £12.94, 3.6 from 5,173 ratings. Reviews often dispute the listed 4 metre jet. It is a poor fit for an air brick.
The top pick is Nippon wasp nest powder 300 g. It is the highest score because the public label carries HSE 9219 and permethrin, with 4.4 from 1,265 ratings at £7.99. The best value is Zero In ZER910 at £5.50, with 4.3 from 3,921 ratings, one point behind on the composite because Nippon’s published label is clearer, not because the cheaper tub failed the entrance job. The 600 ml foam is only for a comb you can see and reach. Raid’s duo is for a wasp in a room, not a nest. None of these scores says a nest dies overnight.
