If you want one answer fast: the Sawyer Products SP5642 20% Picaridin Lotion is the pick worth buying, because it runs up to 12 hours against mosquitoes and ticks and leaves no greasy film or heavy smell behind. The rest of this list covers the natural, DEET-free options that suit kids, sensitive skin, and anyone who cannot stand that sharp chemical scent — plus the one thing that actually decides success in the UK: matching the repellent to the bug you are fighting.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
From a midge-heavy evening by a Scottish loch to a family barbecue where mosquitoes patrol the garden, the right bottle decides whether you stay out past dusk or head indoors. Below you’ll find the practical differences that separate these insect repellent uk options.
Top Picks
How To Choose The Best Insect Repellent UK
British biting insects are a mixed crowd. You have garden and woodland mosquitoes, the notorious Highland midge, and ticks in long grass and bracken. No single bottle is perfect for all three, so the first decision is which pest you actually meet. The second decision is your skin and your nose: do you want a hard-working synthetic active ingredient, or a plant-oil formula you feel comfortable spraying on a child?
Match the active ingredient to the insect
Look at what does the repelling work. Picaridin and DEET are the two synthetics most widely used, and both are measured in hours of protection on the label. Natural options lean on plant oils such as geraniol, lemongrass, and peppermint, and they typically quote shorter windows. A repellent listed against ticks for up to 8 hours and mosquitoes for up to 6 hours is aimed at people who meet both. If midges are your main enemy, check the formula mentions biting flies and gnats, because midges sit in that group.
Check the application format against your day
Lotion rubs in like moisturiser and suits bare arms and legs on a long walk. A spray reaches clothing, sleeves, and trouser legs quickly, which matters because ticks climb up from the grass. Wipes are the lightest to carry and won’t leak in a day bag or a pocket. A packed picnic calls for wipes, a camping trip for a spray, a hike through bracken for a lotion you can rub into bare legs — pick the format that fits that routine, not just the price tier.
Fragrance, skin type, and clothing
A fragrance-free lotion won’t clash with your perfume or aftershave, and it won’t leave an oily sheen. A plant-based spray leaves a lighter, pleasant scent instead, which some people prefer and others find strong. If anyone in your group has sensitive skin or eczema, look for a formula described as non-greasy and dermatologist tested, and test a small patch first. Check the label for fabric and gear guidance too — some formulas state plainly that they won’t stain clothing.

Detailed Reviews
1. Sawyer Products SP5642 20% Picaridin Insect Repellent Twin Pack
Our pick — over 4.5★ from 25,000+ verified ratings; the strongest balance of quality and price.
The fragrance-free lotion that works like moisturiser and keeps biting at bay for a full day outdoors.
For the long hike, the camping weekend, or the back-garden evening that turns into a late one, this is the pick. The headline number is the 20% Picaridin (a synthetic version of the compound found in pepper plants, used to mask the scent that insects home in on), and it is quoted at up to 12 hours against mosquitoes and ticks. That means you apply once at breakfast and mostly forget about it. Against flies, gnats, and chiggers it runs to about 8 hours.
What wins people over is that it disappears into skin. It is listed as non-greasy and fragrance free, so it rubs in like a normal lotion and leaves no oily film on your hands, your watch, your sunglasses, or your fishing line. Owners who covered a fortnight in Africa with it describe using it the way you would use body cream — full coverage, no lingering smell — and report it still did its job. It is also stated as safe for the whole family and safe on clothing and synthetic coatings, so you are not worried about a stray squirt on a jacket.
Two 4-ounce bottles come in the twin pack, one for the house and one for the backpack. The honest trade-off is reapplication: swimming or heavy sweating can thin the layer, so the label says to reapply after either. Some bottles have also been known to weep a little at the seal, so a plastic bag is a cheap insurance policy. The lid pours a wide stream, so tilt it slowly rather than squeezing hard.
Why it earns top spot
- Up to 12 hours against mosquitoes and ticks — apply once and get on with your day
- Fragrance-free and non-greasy, so it vanishes into skin after a minute
- safe for the whole family and won’t damage plastics or synthetic coatings
The fine print
- Reapply after swimming or heavy sweating
- Bottle seal can weep in transit — keep it bagged
- Less effective than a 30% DEET formula, so not a jungle-grade choice
The long-day pick: reach for this if you want one application to cover a hike, a festival, or an afternoon in the garden with no smell and no stickiness.
The one thing to plan for: heavy sweat or a dip in the sea means a top-up, so keep the second bottle in your bag.
2. Grandpa Gus’s Natural Tick and Mosquito DEET-Free Repellent Spray, 2 Pack
The plant-oil spray built for anyone walking through long grass where ticks lie in wait.
If you spend time in bracken, woodland, or rough pasture, ticks are the pest to plan around. This formula leans on Geraniol, Lemongrass, and Peppermint oils and is quoted at up to 8 hours against ticks and up to 6 hours against mosquitoes. The label tells you the smart move plainly: ticks climb, so spray onto trouser legs and sleeves as well as exposed skin. It is described as non-greasy and won’t stain fabric or gear, so treating your walking trousers costs you nothing.
Two 4-ounce bottles come in the pack, and each stands 5.5 inches tall. Put that beside the Murphy’s Naturals wipes, which pack down to a flat 0.7-inch-thick sleeve. The Grandpa Gus’s bottles are the heavier, larger item at 10.58 ounces against 5.93 ounces — so if bulk in a day bag bothers you, that is worth knowing before you choose. For a car-boot kit or a shed shelf, the extra size is a non-issue.
Owners with sensitive skin report it suits them well: the scent is lighter than typical repellents and fades quickly, and it has been used comfortably by people managing eczema. Where the reviews split is on mosquitoes specifically. Some found it held biting insects off through evening garden work; others felt it fell short on that front, even while praising how it handled ticks. The value question draws a mixed response too — some say it earns its place, others want more for the outlay. Think of it as a tick specialist, and it will not let you down.
Where it shines: plant-based oils, a light scent that fades fast, and a fabric-safe spray that lets you treat clothing as well as skin. Ticks up to 8 hours is the number that matters for UK walkers.
Where it fades: the mosquito side is the weaker leg and the one buyers question most. If your problem is garden mosquitoes rather than ticks, the Lemongrass Farms twin pack below is the more balanced natural choice.
Suits you if: ticks are your worry and you want a DEET-free spray you can also put on your trousers and sleeves.
Think twice if: mosquitoes are your main pest — the reviews on that front are genuinely divided.
3. Murphy’s Naturals Mosquito Repellent Wipes 10 Count Pack of 3
Flat, leak-proof wipes that slip into a pocket and never spill inside your bag.
For the day-bag, the school run, a picnic, or a festival, the format is the whole point. These wipes are lemongrass and rosemary oil, quoted at up to 2 hours against mosquitoes and up to 1 hour against ticks per application. That is a shorter window than the sprays, so you re-wipe more often — but nothing leaks, nothing sprays sideways into the wind, and one wipe covers an arm or a pair of legs evenly. The three-pack gives you three sleeve-style packs to leave wherever you might need one.
The compactness is the standout: at 6.25 by 3.5 by 0.7 inches, a pack is roughly a slim wallet you can drop in a jacket pocket. Compare that with the Grandpa Gus’s Tick and Mosquito spray bottles at 1.5 by 1.5 by 5.5 inches and 10.58 ounces — the wipes are the carry-anywhere option and the bottles are the leave-in-the-car option. Wipes are also the easiest way to treat a child’s arms without chasing them around with an aerosol: parents describe ample product on a wipe and no irritation, including on a five-year-old.
Two honest notes. The scent divides people — some describe a fresh lemongrass aroma, others find it strong. And a few owners note a slightly oily feel on the skin right after application, and a drying effect later. Both are worth knowing if you dislike anything sitting on your skin, though for most people the trade is a wipe that genuinely works on the bites.
What buyers love most
- Flat 0.7-inch packs that fit a pocket with zero leak risk
- Easy, even coverage — no aerosol cloud on a windy day
- Described as non-irritating and suitable for children when an adult applies it
Worth knowing first
- Shorter protection window — up to 2 hours max, so top-up often
- The lemongrass scent reads strong to some noses
- A light oily residue is reported before it settles
Grab these if: you want something pocket-sized and spill-proof for short outings, kids, and travel days.
Look elsewhere if: you need hours of cover from a single application — a lotion or a spray will serve you better.
4. Grandpa Gus’s Natural Mosquito DEET-Free Repellent Spray 2 Pack
The same plant-oil family of ingredients, pointed straight at garden mosquitoes.
Grandpa Gus’s makes two sprays, and the difference is which insect each one leads with. This version is the mosquito-facing one: Geraniol, Lemongrass, and Peppermint oils, quoted at up to 6 hours against mosquitoes and up to 8 hours against ticks. It is the same non-greasy, fabric-safe, dermatologist-tested formula you can put on clothing as well as skin — just weighted the other way round from the Tick and Mosquito version above.
The scent is the part people single out. It is a pleasant, plant-forward aroma rather than a chemical one, and it is listed as safe for kids and toddlers when an adult applies it. A little goes a fair way and the 4-ounce twin pack covers plenty of evenings. Made in the USA, no DEET, and described as safe for the whole family but not for pets.
Be clear-eyed on one thing: the mosquito performance here is the most contested element in this whole article. Plenty of buyers report it holds mosquitoes off well, and a review headline of “No More Bites” next to Florida mosquitoes tells you it can work. Others found it simply did not do the job for them. The pattern suggests it varies by person and by location — some skin chemistry and some mosquito populations just respond differently to plant oils. If you want the surest bet, the Picaridin lotion at the top is the safer pick; if you want a natural spray to try first, this is a reasonable one, with a short reapplication window to keep in mind.
Straight read: a genuinely pleasant natural spray for lighter mosquito pressure and for anyone avoiding DEET. The 6-hour mosquito figure is modest but honest for a plant formula.
The caveat: effectiveness is the most debated point in its own reviews, so treat it as a good first natural try rather than a guaranteed shield.
Best for: someone who wants a DEET-free spray with a lovely scent for calm garden evenings.
Skip if: you need certainty against heavy mosquito pressure — that is where the Picaridin lotion wins.
5. Lemongrass Farms Trek Botanical Outdoor Spray 8fl oz Pack of 2
Two large botanical bottles that spray dry and leave no sticky film behind.
This is the natural pick with the most volume: two 8-ounce bottles, 16 ounces in total, made with peppermint, cedarwood, geraniol, and lemongrass oil and no preservatives. The formula is water-based, so it applies easily and dries quickly with no greasy or sticky residue. For daily garden use, sports, or a hiking trip where you want plenty of spray to hand, the twin pack means one bottle at home and one in the backpack or the car.
Two things earn it a place on the list. First, the texture: buyers describe liking the feel of the spray and not feeling the need for a shower afterwards. Second, the coverage — a large bottle goes further than a small one when you are using it on all exposed skin every afternoon. The scent gets consistent praise as fresh and pleasant rather than chemical.
Its reviews carry a caution worth flagging before you buy. The nozzle has failed on some bottles — one buyer found the second bottle completely unusable only after the first ran dry, which is exactly when you do not want to discover a defect. Give both bottles a quick test spray when they arrive, so any faulty nozzle surfaces before you are relying on it. Value also draws a mixed response, with some happy and others wanting more from the outlay.
Why it is versatile
- 16 ounces total across two bottles — plenty for a long trip
- Water-based spray that dries fast with no sticky residue
- Plant-based and preservative-free, with a scent buyers call fresh
Before you buy
- The nozzle has failed on some units — test both bottles on arrival
- The botanical formula runs a shorter window than a synthetic lotion
- Value gets a divided response from its own buyers
Worth it for: families and hobby gardeners who want plenty of a gentle, quick-drying botanical spray on hand for daily use.
The catch: check both nozzles the day they arrive, and expect to reapply more often than you would with the leading lotion.
Know the Specs
Protection window (hours)
This is the single most useful number on any bottle. It tells you roughly how long the repellent keeps working before you need more, and it is usually quoted separately for different insects. A repellent listed at up to 8 hours against ticks and 6 against mosquitoes is not the same as one at up to 2 hours for mosquitoes. The shorter the window, the more often you stop what you are doing to reapply — a 2-hour wipe means topping up mid-picnic, while a 12-hour lotion covers a full day out.
Active ingredient and strength
The active ingredient is what repels the insect. Picaridin and DEET are the two common synthetic options, with Picaridin usually chosen because it is odourless and won’t damage plastics. Plant oils like geraniol, lemongrass, peppermint, and rosemary are the natural route and tend to quote shorter windows. The strength is normally given as a percentage, such as 20% Picaridin. Match the ingredient to the insect you actually meet — 20% Picaridin for up to 12 hours against mosquitoes and ticks, plant oils for shorter windows — and remember that a natural formula is a gentler choice rather than an equal one.

For most people shopping for the best insect repellent uk, the Sawyer Products SP5642 20% Picaridin Lotion is the one to start with.

And for pockets, kids, and short outings, the Murphy’s Naturals Wipes are the spill-proof option that goes anywhere. Match the pick to the insect you actually meet — midges, ticks, or garden mosquitoes — and one bottle will carry you through the season.
