The best Spider sprays, compared.
Top pick: Pestshield spider and creepy crawly killer (6 x 200 ml) Best value: Acana Natural Spider Stopper (500 ml) – About £7.99 for one 500 ml bottle with peppermint and clove oils named, 3.9 from 485 ratings. The lowest shelf price for a single bottle, not the lowest price per litre. Updated October 2026.
A spider spray is a bottle or an aerosol for house spiders that come indoors, most often in autumn. You buy one on amazon.co.uk either as a barrier for frames and thresholds, or as a contact spray that kills a spider you hit. Those jobs are not the same. A barrier is sold to leave the spider alive. A killer is sold to stop the one in front of you. Sealing gaps, vacuuming webs and fewer prey insects still come first. You tell a suitable bottle by the job on the label, a named oil or active, a repeat interval, and where you may spray. Indoor frames, doorways and skirting are the default. Sheds and outdoors need a label that allows them. Rain strips an outdoor film. Do not soak beds, cots or food surfaces unless the label says so. A killer follows biocidal product type 18. A repellent follows type 19. No active and no HSE number means the bottle is not shown as authorised. What to check on the label is in the [spider spray buying guide](/hub/pest-control/spider-spray/sub/spider-spray-buying-guide).

Personal buying guide
Question 1 of 2
What should the spray do?
Pestshield is six 200 ml unscented aerosol cans, 1.2 litres at £12.10, sold to kill spiders and crawling insects when you spray them directly. Across 122 amazon.co.uk reviews it holds 4.4 stars. Buyers report that a direct hit kills small spiders within minutes. Reviewers also note that a larger spider can walk off, that continuous spraying empties a 200 ml can in about 20 seconds, and that the spray does not stop the next spider entering. The saved page does not name an active ingredient, an HSE number or a residual interval. The title says insect killer, one bullet says insect repellent, and a size field prints 33.33 ml beside 200 ml. Dividing £12.10 by 1.2 litres is about £10.08 a litre. That arithmetic does not make it a cheaper barrier. Treat it as a contact knock-down spray.
Pros
Cons
Best for: Buyers who want an unscented contact aerosol to kill a visible spider on the spot, rather than a scented frame deterrent.
Less suitable: Households who want a barrier that leaves no dead spiders, or anyone who needs a named active on the page before they buy.
Specifications
Common questions
Does this spray deter spiders or kill them on contact?
The title calls it an insect killer. One bullet prints insect repellent. Customer reviews state that a direct spray kills spiders within minutes and does not keep new spiders away.
Does the listing name the active substance?
No. The saved amazon.co.uk page does not state an active ingredient, an HSE number or a repeat interval.
Why does the size line say 33.33 ml?
The title and bullets state 6 x 200 ml aerosols. A separate size field prints 33.33 ml, which is 200 ml divided by 6. Ignore that field.
This STV International twin pack is two 500 ml bottles, 1 litre at £12.90, sold under a Zero In humane mint title for windows and doors. Across 517 amazon.co.uk reviews it averages 4.1 stars. Buyers who saw fewer spiders report repeating the spray about every two weeks, or after rain washed an outdoor film away. One reviewer says two 500 ml bottles only just covered a three-bedroom semi-detached house. Others say spraying in hot weather with the windows open did not stop spiders coming inside. The listing conflicts with itself: the title is a humane mint deterrent, and the bullets open with a killer claim for beds, kennels and carpets. Do not treat those bullets as the formula, and do not expect an insecticide from them. At £12.90 a litre it costs more per litre than the STV981 triple pack.
Pros
Cons
Best for: Shoppers who specifically want two bottles of Zero In mint spray and will follow the physical bottle, not the mismatched Amazon bullets.
Less suitable: Buyers who want the listing and the bottle to agree, or a lower price per litre from the three-bottle STV981 pack.
Specifications
Common questions
Why do the bullets mention killing when the title says humane?
The title is a Zero In humane mint spider repellent for windows and doors. The bullets open with a killer claim and say insects are killed within minutes. Treat the bullets as a listing conflict, not as the formula.
How often did reviewers re-apply it?
Reviewers who reported fewer spiders describe repeating the spray about every two weeks, or after rain washed an outdoor treatment off.
Are surface and pet questions answered on the page?
No. The saved listing includes questions on surfaces, strong scent and pets, and leaves them unanswered. Read the bottle label.
Zero In STV981 is three 500 ml bottles, 1.5 litres at £17.25, or £11.50 a litre, of mint oil extract for indoor window frames, doorways and other entry points. The listing says to re-apply every two to three weeks or after cleaning, and the nozzle twists between a mist and a stream. Across 13,064 amazon.co.uk ratings it holds 3.9 stars. Amazon often rolls parent reviews together, so that count is not 13,064 purchases of this triple pack. Feedback splits between quieter rooms over a couple of days and spiders back within days. Reviewers also report a trigger neck that leaks onto the hands, and a strong peppermint scent when first sprayed. The specification row prints aerosol while the bullets describe a trigger bottle, and the title says non-toxic. The 2023 safety data sheet lists peppermint oil under 1%, an EUH208 skin-sensitiser line, and says to keep the bottle out of reach of children. It is the top pick here because the per-litre price, the named extract and the stated repeat interval are on the page.
Pros
Cons
Best for: Households treating several indoor windows, doors and skirting gaps every two to three weeks who want the lowest per-litre cost among the mint barriers.
Less suitable: Buyers who only want a single trial bottle, dislike a strong peppermint scent, or expect a contact spray that kills a spider on sight.
Specifications
Common questions
How often does the listing say to re-apply?
The title and bullets state that the barrier lasts up to 2–3 weeks and should be re-applied every 2–3 weeks or after cleaning.
Is it an aerosol or a trigger spray?
The specification row says aerosol. The bullets and customer reviews describe a trigger bottle with a nozzle that twists from stream to mist.
Does the listing say it harms spiders?
No. The bullets state that the mint oil extract barrier does not harm spiders. The title also says non-toxic, which biocidal advertisements must not claim.
Acana Natural Spider Stopper is one 500 ml water-based spray at £7.99, about £15.98 a litre, using peppermint and clove oils around the home, garages and sheds. Across 485 amazon.co.uk reviews it averages 3.9 stars. Buyers use it on window frames, doorways and shed thresholds. The Amazon title claims up to 12 weeks and says the formula will not stain. The bullets give no week count. A retailer directions page for the same 500 ml bottle says to repeat every two to three weeks, so the bottle wins over the title. Reviews divide between fewer spiders in treated rooms and spiders back across frames after a few days. The saved listing leaves questions on pet safety and scent strength unanswered. It is the best value when you want one bottle rather than a multi-pack. It is not the lowest price per litre.
Pros
Cons
Best for: Shoppers who want one bottle at about £7.99, with peppermint and clove oils, for a few window frames, a utility room or a garden shed.
Less suitable: Anyone expecting one spray to last 12 weeks, or anyone who needs 1.5 litres for a whole house at the lowest cost per litre.
Specifications
Common questions
Does Acana Spider Stopper kill spiders?
No. The title and bullets describe it as a deterrent, with no dead spiders, using a water base with peppermint and clove oils.
Where does the listing say you can use it?
The bullets name around the home, garages, sheds and other indoor spaces. The title also states it will not stain.
Is pet safety answered on the listing?
No. The saved listing includes a question on pets and strong scent, and neither is answered in the specification block. Read the bottle.
Invigortex WildGuard is one 1 litre ready-to-use bottle at £12.95, about £12.95 a litre, for indoor and outdoor entry points including windows, doors, skirting, sheds and garages. The bullets name peppermint, lavender and eucalyptus oils with castile soap. You shake the bottle and do not dilute it. The bullets say to test a hidden patch, keep the bottle away from children, and never spray people or animals. The saved amazon.co.uk listing has no customer ratings and no reviews, so there is no UK buyer note on the nozzle, the scent or how long the film lasts. The page also omits a week count and prints a 5 litre option name in the size field against the 1 litre volume. Until reviews exist, it sits behind the Acana bottle and the Zero In triple pack.
Pros
Cons
Best for: Shoppers who want 1 litre of peppermint, lavender and eucalyptus for sheds or thresholds and will try a listing with no reviews.
Less suitable: Buyers who rely on amazon.co.uk reviews, or who want a lower price per litre from the Zero In triple pack.
Specifications
Common questions
Does it need to be diluted?
No. The bullets state that the 1 litre bottle is ready to use, with no dilution. Shake it before you spray.
Can you use it on every surface, or on pets?
The bullets say to test an inconspicuous area first, keep the bottle out of reach of children, and never spray directly onto people or animals.
Are there customer reviews on the saved listing?
No. The saved amazon.co.uk file has no star rating and no review count for this bottle.
Five amazon.co.uk spider sprays are scored from the captured star rating with a log-scaled review count, whether the page names an oil or active and a repeat interval, and price per litre with deductions when the title fights the bullets. There is no laboratory test. Listings with no customer ratings score zero on the review component and cannot take a category badge. The top pick is the highest score. Best value is the single bottle with the lowest shelf price when you want one bottle rather than a multi-pack. A lower price per litre on a contact killer is not treated as a cheaper barrier.
Stars and review sample
60%amazon.co.uk stars count with the review count on that listing, on a log scale across the five kept pages. A large count ranks above a higher star line from a thin sample. A page with no ratings scores zero here.
Named formula and interval
25%Points follow a named oil or active, and a practical re-application window when the listing prints one. No active and no repeat interval score lower. A week count that appears only in a title, not in the directions, is not taken as the interval.
Price per litre and consistency
15%Shelf price per litre uses the captured GBP price and the title volume. Points come off when the title and the bullets describe different products, or when a size field contradicts the pack.
Start with the job on the label, then the named oil or active, then the repeat interval. A spider spray is either a barrier for frames and thresholds or a contact spray for a spider you can see. Shelf prices captured here run from about £7.99 to about £17.25. Nothing on this page is a laboratory test, and none of the five listings prints an HSE number.
A spider spray on amazon.co.uk is one of two products. A barrier goes on frames, doorways, thresholds and skirting. A contact spray is for a spider you can see. Reviews of that type describe death in minutes and little stay-away effect. The British Pest Control Association still starts with a glass and a card, web removal, and fewer prey insects. Native spiders are not described as a health threat. False-widow call-outs peak in October. Judge the bottle.
Pestshield reviews describe death in minutes and little stay-away effect. Zero In’s listing says the mint barrier does not harm spiders. The twin pack’s killer bullets contradict that kind of title. Match the job before the price.
Acana’s amazon.co.uk title says up to 12 weeks. A retailer directions page for the same 500 ml bottle says every two to three weeks. Zero In states two to three weeks, or after cleaning. The bottle wins.
Barriers belong on frames and thresholds, not the middle of the room. Do not soak beds, cots or food-prep areas unless the label says so. Rain strips outdoor film. Do not treat the twin pack’s killer bullets as a named insecticide.
Deter and kill are different products. A mint barrier is sold for entry points and is not a promise that every spider stays out. A contact killer is for the spider you hit, and reviews of the unscented aerosols here say it does not keep the next one out. Stars do not encode that fork. A higher star line on a killer is still a killer. Read what is named. Peppermint and clove, or peppermint with lavender, eucalyptus and castile soap, are on those pages.
Indoor frames are the default. Sheds and outdoors need a label that allows them. Do not soak beds, cots or food surfaces unless that label says so. Open windows in hot weather bypass a frame film. Proof is the amazon.co.uk count on that listing, not a slogan. No ratings means no review component. Non-toxic, natural, pet safe and HSE approved are not clearances. Biocidal advertisements must not use those words, and the Health and Safety Executive does not endorse products.
Three typical situations, each with a recommendation from this comparison.
You want a mint barrier on indoor frames and you will repeat it every two to three weeks. Zero In STV981 is three 500 ml bottles, 1.5 litres at about £17.25, about £11.50 a litre, with 3.9 from 13,064 ratings. The listing says the extract does not harm spiders. Reviewers report leaking triggers and spiders back within days. The specification says aerosol. Skip it if you wanted one trial bottle or a spray that kills on contact.
You want the lowest shelf price for a single bottle, not the lowest price per litre. Acana Natural Spider Stopper is 500 ml at about £7.99, peppermint and clove oils, 3.9 from 485 ratings, for the home, garages and sheds. The title says up to 12 weeks. A retailer directions page for the same bottle says every two to three weeks. Leave it if you need 1.5 litres for a whole house.
You want a direct hit, not a scented frame film. Pestshield is six 200 ml unscented aerosols at about £12.10, with 4.4 from 122 ratings. Reviews say small spiders die within minutes, a large one may walk off, and new spiders still come in. The listing names no active and no repeat interval. It is the wrong row if you wanted no dead spiders.
The top pick is Zero In spider repellent STV981, three 500 ml bottles, at about £17.25. It is the highest score: 1.5 litres at about £11.50 a litre, a named mint oil extract, a stated repeat of every two to three weeks or after cleaning, and 3.9 from 13,064 amazon.co.uk ratings. That count is the figure on the page, and Amazon often rolls reviews up to a parent. Reviewers report leaking triggers, a strong mint scent, and spiders back within days. The specification says aerosol against a trigger bottle, and the 2023 safety data sheet carries an EUH208 line for peppermint oil. The best value is Acana Natural Spider Stopper at about £7.99 for one 500 ml bottle, 3.9 from 485 ratings, when you want a single bottle rather than a multi-pack. Its title says up to 12 weeks. A retailer directions page says every two to three weeks. About £15.98 a litre is higher than the triple pack. None of these scores is a laboratory test, and none of the five pages prints an HSE number.
Acana Natural Spider Stopper (500 ml)
About £7.99 for one 500 ml bottle with peppermint and clove oils named, 3.9 from 485 ratings. The lowest shelf price for a single bottle, not the lowest price per litre.
