Insect bites and bed bugs in hotels usually cause itchy red lumps that settle within a week. Wash the bites, use a cold compress and ask a pharmacist about anti-itch treatment. If bites appear in lines on skin exposed during sleep, tell the hotel and protect your luggage. Spreading redness, fever or facial swelling needs a doctor.
Mosquito, flea or bed bug?
It is often impossible to be sure which insect bit you, and the treatment is similar. A few patterns help:
- Mosquito bites: scattered, itchy lumps on exposed skin, especially after evenings outdoors or with windows open in summer.
- Bed bug bites: often in lines or small clusters on areas exposed while sleeping, such as the face, neck, arms and hands. They may appear a day or more after the bite.
- Flea bites: small, very itchy spots, often around the ankles and lower legs.
Describe the pattern and timing to a doctor rather than trying to name the insect.
Signs of bed bugs in your room
NHS guidance lists signs to look for:
- Small spots of blood on the sheets
- Tiny dark spots on mattresses and furniture
- Small insects or shed skins in the seams of the mattress, the headboard or furniture joints
- An unpleasant musty smell in the room
Bed bugs are not a sign of a dirty room; they travel in luggage and can turn up anywhere, including good hotels.
What to do about the room and your luggage
If you think there are bed bugs:
- Tell reception or the host straight away and ask to move to a different room, preferably not next to or above the original one.
- Keep luggage off the floor and bed, on a luggage rack or in the bathroom.
- Check your luggage, clothes and seams before moving them.
- Wash clothes on a hot wash or tumble-dry them on high heat.
- Inspect your luggage again when you get home before unpacking inside.
Photograph the evidence and keep a note of what the hotel says, in case you need to make a complaint or claim.
Caring for bites
Most bites settle on their own. NHS guidance suggests:
- Wash the area with soap and water.
- Apply a cold compress or a cloth-wrapped ice pack for about 10 minutes.
- Raise the affected area if it is swollen.
- Try not to scratch, to reduce the risk of infection.
- Ask a pharmacist (Eczane) about antihistamines or an anti-itch cream, and tell them about any conditions or medicines.
For mosquitoes, use insect repellent, keep windows screened or closed in the evening and ask your hotel about plug-in repellent devices. "Sinek kovucu" means insect repellent. If you plan trips to rural areas or forests, check yourself for ticks afterwards, remove any carefully, and get medical advice if you develop a fever in the following days.
Preventing bites in Istanbul
Mosquitoes are most active in the evening and at night from late spring to autumn, especially near water, in parks and on the Princes' Islands. A few simple habits reduce bites a lot:
- Use an insect repellent on exposed skin in the evening, reapplying as the label directs, and put sunscreen on first if you use both.
- Wear long sleeves and trousers for evening meals by the Bosphorus or in garden restaurants.
- Keep windows closed or screened in the evening, and use the air conditioning or a fan at night; mosquitoes struggle in moving air.
- Check your bed and luggage rack for signs of bed bugs when you first arrive, before you unpack.
- Store luggage zipped and off the floor throughout the stay.
Bee and wasp stings
Wasps are common at outdoor cafés in late summer, drawn to sweet drinks, fruit and baklava. Check cans and glasses before sipping, and keep food covered. If you are stung, scrape the sting out sideways with a fingernail or the edge of a card if it is still in the skin, wash the area, and apply a cold compress. Pain, redness and swelling around the sting are normal and usually settle within a day or two.
A sting in the mouth or throat, or any sign of a wider allergic reaction such as hives elsewhere on the body, swelling of the lips or difficulty breathing, needs urgent help. Our guide to allergic reactions while travelling explains the signs.
What to tell the doctor
A doctor will want to know when and where the bites appeared, whether they are in lines or scattered, whether anyone travelling with you has similar bites, and whether you have had a fever, swollen glands or feel unwell. Photos taken each day show whether redness is spreading. Mention any recent trips to rural areas or forests, and any medicines or creams you have already used.
Useful words at the pharmacy

- Tahtakurusu: bed bug
- Kaşıntı: itching
- Sinek kovucu: insect repellent
Getting home without bed bugs
Before you pack to leave, check your luggage seams, pockets and shoes in good light. At home, unpack straight into the washing machine where possible, wash on a hot cycle or tumble-dry on high heat, and vacuum the suitcase before storing it. Keep the case away from beds and sofas for a few days.
When a bite needs medical attention
See a doctor, at your accommodation or a clinic, if:
- The bite is not improving after a few days, or is getting worse
- A large area around the bite, roughly 10 cm or more, becomes red and swollen
- There are signs of infection: pus, increasing pain, warmth, or redness spreading
- You have a fever, swollen glands or flu-like symptoms
- You were bitten or stung in the mouth or throat, or near the eyes
A doctor visit at your hotel can assess an infected or very swollen bite, and a nurse can follow up with wound dressing at your hotel if needed.
