Best mosquito repellent spray in this UK set

Updated: 23 October 2026

You want a name, not another ingredient lecture: which bottle on amazon.co.uk to put in the basket, and which listing to leave. In this set the top pick is Pyramid Trek 50, the most-reviewed spray that states 50% DEET, in a 100 ml bottle at £9.99. The best-value DEET-free bottle is the Autan picaridin pump at £8.50. Star rating alone would have sent you to a 4.6-star multipack whose brand field does not match the title. The full table is on the [mosquito spray comparison](/hub/pest-control/mosquito-spray). We compared the saved listings on 21 October 2026 and did not cage mosquitoes. A qualifying purchase can earn a commission at no extra cost to you.

What best means here

Best, on this page, means the skin spray that states the active UK travel advice names first, with enough reviews to show the complaints, at a size you can finish. That is 50% DEET on skin, for people who tolerate it. UKMEAG puts 50% DEET ahead of the alternatives. If you will not use DEET, the second pick is a picaridin spray at about 20%. The rule behind the criterion is on the mosquito spray buying guide. The 4.6 from 1,810 reviews sits on a £21.20 pack of three 125 ml aerosols titled Jungle Formula Maximum. The brand field says LUHME and the saved bullets do not print a DEET percentage. Which? has described Pyramid Trek 50 as highly effective in its own testing. That is not a ranking of these rows.

Pyramid Trek 50

Pyramid Trek 50, ASIN B000VRZ26Y, is 100 ml at £9.99, 4.4 from 5,101 reviews. The listing states 50% DEET, up to 6 hours, unscented, and ages 12 and over. People report fewer bites on holidays and in UK heat, and also an oily or thick feel, marks on white shirts, the odd leak, and, in one review, plastic that melted. Ticks are asked on the page and are not named in the bullets. It is the top pick when everyone who will wear it is 12 or over. It is a weak choice if you need a label that says under 12, a DEET-free formula, or a room fly spray.

Lifesystems and Autan

Lifesystems Expedition, URL ASIN B082JJ5N9V, is a 50 ml pump at £8.95, 4.5 from 1,300 reviews. It states 50% DEET, up to 8 hours, and children aged 2 and over. The bullets call it non-flammable and flight carry-on compliant, which is the brand's claim. Reviewers mention grease, a squirt rather than a mist, leaking caps, and sticky nail polish. The details block prints ASIN B082JHVDWJ while the URL is B082JJ5N9V. You get half the fill of Pyramid for almost the same money. If the problem is DEET itself, Autan, B088RTJXHS, is £8.50 for 100 ml, 4.5 from 2,234 reviews, DEET-free and picaridin-based, for children over 2. The bullets give up to 8 hours for common mosquitoes, 6 for tiger mosquitoes, and 4 for biting flies and ticks. The percentage is missing from those bullets; the amazon.co.uk description states 20% icaridin. The strength comparison is on DEET or picaridin.

What not to call the best

The Jungle-titled aerosols are the star-rating trap: 125 ml a can, awkward against a 100 ml cabin rule at many UK airports, with smell, oil, plastics, and broken caps in reviews. Buy that pack only after you have checked the can for the active and the brand. Wilson's citronella area spray is £9.99, 3.9 from 88 reviews. The catalogue says 250 ml, and the bullets say it deters rather than kills. Skin Shield is £9.99, 4.2 from 15 reviews, with citronella and lemongrass, a from-6-months line, and a 100 ml field against a bullet that says 250 ml. UK travel advice does not treat citronella blends as reliable repellents. Raid, £8.70, 4.5 from 347 reviews, is an indoor killer. Reviewers describe fast fly knockdown. Keep it off skin.

Common questions

Which bottle is the top pick here, and for whom?
Pyramid Trek 50, when you want stated 50% DEET in 100 ml at £9.99 and everyone using it is 12 or over. The reason is the active plus 5,101 reviews. Skip it for a 2+ label or a DEET-free bottle.
Why not the 4.6-star pack?
That 4.6 from 1,810 reviews is three 125 ml aerosols titled Jungle Formula Maximum, with a LUHME brand field and no DEET percentage on the saved bullets. Each can is also over the 100 ml size many UK airports use at security.
What is the DEET-free pick?
Autan at £8.50 for 100 ml, 4.5 from 2,234 reviews. Treat 20% icaridin as the figure in the amazon.co.uk description, because the short bullets omit it. Choose it when you are avoiding DEET.
Is Lifesystems better than Pyramid?
Better when you need 50 ml, a 2+ age line, and a carry-on claim. Worse when you want 100 ml and the largest review count. Both state 50% DEET. The details-block ASIN does not match the URL.
Should I buy the citronella sprays?
Only for a patio or bin smell with Wilson, or a scented mist with Skin Shield, when you are not relying on it for a malaria-risk trip. The review bases are 88 and 15.
Is Raid a best mosquito spray?
Not for bite prevention on skin. Raid at £8.70 is the indoor flying-insect killer, with fast knockdown in reviews. Actives, pets, and stains are unanswered on the saved page.
Who should skip Pyramid?
Skip it if the user is under 12 and you will not ask a pharmacist, if you want DEET-free, or if you need a room killer. Skip it too if an oily finish and marks on light clothes are already a deal-breaker.
