- Treated online: Yes, usually. Photo and video assessment, prescription when appropriate.
- Midge bites often swell and blister more than mosquito bites; a large local reaction is common and rarely dangerous.
- Midges swarm at dawn and dusk near water and still air; covering up and repellent at those hours prevents most bites.
- Only female midges bite, and the midges found in Europe do not transmit disease to humans.
- A bite still getting worse after 48 hours deserves a medical opinion.
Midge bites are miserable rather than dangerous. Call 112 instead of booking if bites are followed by swelling of the face, lips, tongue or throat, difficulty breathing, widespread hives with faintness, or collapse. Redness spreading fast with fever needs same-day in-person care.
How an online consultation helps with midge bites
? Before your appointment: take two daylight photos: a sharp close-up of the worst area with a coin or ruler for scale, and a wider shot showing the spread of bites. If swelling is growing, photograph it morning and evening; the sequence tells the doctor whether it is peaking or advancing.

normal bites, large local reactions, scratched-open patches and early infection each need a different plan, and the difference shows in photos taken a day apart.
after assessment, the doctor can prescribe stronger topical steroids and the right antihistamine strategy instead of another round of whatever the supermarket had.
heavily scratched midge bites are a classic route to skin infection; the doctor checks your photos against the 48-hour rule and treats what needs treating.
repellents, timing and clothing advice matched to where the midges keep finding you, whether that is a Scottish glen, a lakeside cabin or your own garden.
What do midge bites look like?
Midge bites appear as clusters of small, red, intensely itchy bumps, often a dozen or more at once on skin that was exposed outdoors: ankles, wrists, the hairline, ears and the back of the neck. Each bite is usually smaller than a mosquito bite, but the itch is often worse, and in people who react strongly the bumps merge into swollen, hot patches or form small blisters.[2] The number is the giveaway: midges attack in swarms, so where a mosquito leaves one weal, midges leave a constellation. Bites usually calm over three to seven days, with scratched or blistered bites taking longer.[4]

Can midge bites cause an allergic reaction?
Yes. Every midge bite involves a small allergic-type response to midge saliva, which is why it itches, and some people go further, developing large local swellings or widespread reactions. A true midge bite allergic reaction severe enough to be dangerous is rare, but it exists, and knowing the four levels helps you match your response to what is happening.[1] Reactions also differ between people and seasons, so last year’s mild bites do not guarantee this year’s.
Normal local reaction
Itchy red bumps that peak over the first day or two and fade within a week. Annoying, completely expected, and safely managed with self-care: cold compresses, antihistamines and hydrocortisone cream.
Large local reaction
In sensitised people, single bites swell into hot, red, itchy plaques several centimetres across, sometimes with blistering, peaking around 24–48 hours and lasting up to a week or more. Uncomfortable and alarming to look at, but still a local reaction; it responds to regular antihistamines and prescription-strength topical steroids after assessment, and it is the level of reaction an online consultation handles particularly well.
Widespread hives
Itchy raised weals appearing beyond the bitten skin, on areas that were never bitten, mean histamine is being released more widely. This deserves a same-day medical review even when breathing is normal; treatment is usually antihistamine-based, and our hives page explains the condition itself.
Anaphylaxis
Extremely rare with midges, but it is the level everyone should be able to recognise: swelling of the face, lips, tongue or throat, difficulty breathing or swallowing, wheeze, dizziness, faintness or collapse within minutes to an hour of bites. That is a 112 emergency, not an online appointment, and adrenaline, not antihistamines, is the treatment that saves lives.[3]
Where and when do midges bite?
Biting midges thrive wherever damp ground, still air and warm summers meet. Scotland’s Highlands and west coast are the famous example: the Highland midge emerges from boggy ground in numbers that can define a holiday, typically from late spring to early autumn. But midges are a European phenomenon, not a Scottish one: Scandinavian lakes and forests, Alpine valleys, Irish moorland, coastal marshes from the Atlantic to the Baltic, and river deltas across the continent all breed them. They swarm at dawn and dusk, on still, humid, overcast days, and near standing water and long vegetation; strong sunshine dries them out and even a light breeze grounds them, which is why the windy side of a beach is bite-free while the sheltered picnic spot is not. Only the females bite, taking a blood meal to mature their eggs, and unlike mosquitoes they cannot bite through fabric, so covered skin genuinely is safe skin. Midges in Europe do not transmit disease to humans; the misery they cause is real but purely skin-deep.[2]
What the doctor checks in an online midge bite consultation
The assessment is structured, and the pattern does most of the talking. In a midge bite consultation, the doctor will typically check:
- The bite pattern and count: clustered bites on exposed skin point to midges; lines under clothing or bites appearing overnight indoors point elsewhere.
- Where you were bitten: boggy ground, lakesides, coastal marsh or garden at dusk, and in which region, which frames the season and the culprit.
- The reaction level: normal bumps, large local plaques, blistering, or any weals beyond the bitten skin, graded from your photos.[1]
- The 48-hour trend: settling, peaking or spreading, which is the main line between reaction and infection.
- Signs of infection: spreading redness, warmth, pus, swollen glands or fever, checked against your timeline.
- Any systemic features: hives elsewhere, swelling away from bites, wheeze or faintness, which change the urgency entirely.
- Health background and medicines: eczema, diabetes, immune-suppressing treatment and pregnancy, which change infection risk and which treatments the doctor recommends.
Which midge bite treatment might the doctor recommend?
Treatment follows the reaction level. This is the decision framework our doctors use, aligned with European and UK guidance on insect bites:[1]
Swipe sideways to compare →
| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Clusters of itchy bumps, settling over days | Cold compress, pharmacy antihistamine, hydrocortisone cream | Usually yes, if reassurance or identification is wanted | Not usually needed |
| Large hot swollen plaques or blistered bites | Regular oral antihistamine plus prescription-strength topical steroid after assessment | Usually yes | Swelling still advancing after 48 hours despite treatment |
| Widespread hives beyond the bitten skin | Same-day review and antihistamine-based treatment | Often yes, same day | Any breathing difficulty, throat tightness or faintness is a 112 emergency |
| Redness spreading after 48 hours, pain, pus or fever | Assessment for infection; antibiotics only if there are bacterial signs | Often yes, with clear photos | Red streaking, fever with shivering or rapid spread need same-day in-person care |
| Face or throat swelling, wheeze, collapse | Emergency treatment for anaphylaxis | No | Call 112 immediately[3] |
Availability of individual medicines and who may prescribe them vary by country; your doctor confirms what applies where you are.

What you can do yourself
Wash the bitten skin, cool it with a cold compress or a cloth-wrapped ice pack for ten minutes at a time, and take a non-drowsy pharmacy antihistamine such as cetirizine or loratadine; taken regularly during a midgy week rather than after each flare, it works noticeably better. One percent hydrocortisone cream calms individual bites, and keeping nails short limits the damage when you scratch in your sleep.[4] Leave blisters intact. What does not help: antiseptic creams on unbroken skin, and folk remedies from bog myrtle to vinegar, which have charm but no evidence.[1]
Prescription treatment
A prescription is never issued without a consultation; the doctor grades the reaction first. Large local reactions usually earn a more potent topical corticosteroid and a structured antihistamine plan, sometimes with a sedating antihistamine at night while the itch peaks. Widespread hives are treated with regular antihistamines and reviewed. Infected bites get an antibiotic course matched to local guidance, and the stewardship line applies: antibiotics are only prescribed when there are genuine signs of bacterial infection, such as spreading redness after 48 hours, pus or fever, because they do nothing for allergic swelling or itch.[1] For people whose every summer is defined by dramatic reactions, the doctor can also discuss whether formal allergy assessment adds anything, honestly including when it does not.[3]
How can I prevent midge bites?
Midge prevention is about stacking small advantages, because no single measure stops a determined swarm:
- Repellent on every exposed patch: DEET or icaridin products are the evidence-backed core; reapply as directed, especially after sweating or swimming.[1]
- Cover up, tightly woven: midges cannot bite through fabric, so long sleeves, trousers tucked into socks and a buff around the neck remove most of the target area.
- A fine-mesh head net: in serious midge country, a head net over a brimmed hat is the difference between an evening outdoors and a retreat indoors; standard mosquito mesh is too coarse, so look for midge-proof mesh.
- Use wind and sun: midges are grounded by breeze and strong sunshine. Choose the windy beach over the sheltered hollow and the open ridge over the still forest edge at dusk.
- Time your day: dawn and dusk are peak biting hours; midday is usually manageable, and swarms fade quickly once you move away from breeding ground.
- At home: fine window mesh in bedroom windows and dealing with permanently waterlogged corners of the garden reduce the nightly supply.
Travelling to midge country elsewhere in Europe? Pack repellent and any antihistamine that works for you rather than hunting pharmacies on arrival, and if bites still get the better of you mid-trip, an online consultation works from a Highland cottage as well as it does from home. Our guide to skin problems while travelling in Europe covers the wider holiday skin survival kit.
When we treat midge bites online, and when we refer you
We treat online: itchy, swollen or blistered midge bites needing more than pharmacy care; large local reactions that need grading and a proper treatment plan; widespread hives without breathing symptoms, the same day; bites with early signs of possible infection that clear photos can settle; and prevention planning for a season or a trip. If the bites turn out to be from gnats or mosquitoes, the plan simply adjusts; the assessment is the same.
We refer or redirect you: any features of anaphylaxis go to 112 before anything else; rapidly spreading redness, red streaking or fever with shivering needs same-day in-person assessment; bites around the eye with swelling that closes the lid need an in-person check; and people with previous serious systemic reactions to bites should carry an emergency plan agreed with an allergy specialist, which we help arrange rather than replace. Midge bites sit alongside the other bites and stings our doctors assess online.
When to get in-person care
Call 112 immediately if bites are followed by swelling of the face, lips, tongue or throat, difficulty breathing or swallowing, wheeze, widespread hives with faintness, or collapse: these are signs of anaphylaxis, which is very rare with midges but always an emergency.[5] Get same-day in-person care for a red streak spreading from a bite, fever with shivering, or redness expanding by the hour.

Frequently asked questions about midge bites
Can an online doctor prescribe midge bite treatment in the EU?
Yes, after a consultation. A prescription is never issued without one: the doctor grades your reaction from photos and video first, then can prescribe antihistamines, prescription-strength steroid creams or, where there are genuine signs of bacterial infection, antibiotics. Prescriptions can be sent to a pharmacy near you in most EU countries, and prescribing rules vary by country.
How much does a consultation about midge bites cost?
A video consultation costs €47. The exact price is shown before payment, and there is no subscription. If the doctor can’t treat you online, you get a full refund and clear directions to the right care.
How long do midge bites last?
Most midge bites settle within three to seven days, with the itch peaking in the first day or two. Large local reactions can take a week or more to flatten, and bites that have been scratched open or infected last longer. A bite still getting worse after 48 hours deserves a medical opinion.
Why do midge bites swell up so much on me?
Midge bites swell up so much because sensitised skin answers each bite with an exaggerated allergic-type response, not an infection. Reactions to midge saliva vary enormously between people: the swelling is a large local reaction, a hot, red, itchy plaque that peaks over one to two days, and it responds to antihistamines and steroid creams rather than antibiotics.
What is the difference between midge bites and mosquito bites?
Midges attack in swarms and leave clusters of small bites on exposed skin, usually at dawn or dusk near water or boggy ground. Mosquitoes bite singly, leave larger individual weals, can bite through thin fabric, and whine audibly at night. The treatment overlaps; the prevention differs in detail.
Do midges in Scotland carry disease?
No, Highland midges, like other European midges, do not transmit any disease to humans. Their bites can be numerous and intensely itchy, and scratched bites can become infected, but the bite itself carries no infection. Repellent, cover-up clothing and a fine-mesh head net are the classic defence.
When should I worry about a midge bite reaction?
Seek same-day help for hives spreading beyond the bitten skin, redness that keeps expanding after 48 hours, pus, or fever. Call 112 immediately for swelling of the face or throat, difficulty breathing, wheeze or faintness after bites: those are signs of anaphylaxis, which is rare with midges but always an emergency.
