Quick answer
To treat bed bug bites, wash them with soap and water, apply a cold compress, then use an over-the-counter hydrocortisone cream or calamine lotion and take an oral antihistamine if itching is strong. Keep the bites clean and do not scratch. Most bites heal on their own in 1 to 2 weeks. See a doctor for signs of infection, blisters or an allergic reaction. To stop new bites, the bed bugs in your home must be treated by a professional.
Bed bug bites are rarely dangerous, but they can be itchy, sore and slow to fade, especially if you have a lot of them. This step-by-step guide shows you exactly what to put on bed bug bites, which home remedies are worth trying, how to help the skin heal without marks, and when you need medical care.
As a California bed bug control company, we also want to be clear about one thing from the start: treating the bites and treating the bed bugs are two different jobs. This guide covers both.
Key takeaways
- Most bed bug bites need only simple home care and heal in 1 to 2 weeks.
- Step 1 is always soap and water. Step 2 is cooling the skin. Step 3 is an anti-itch cream or lotion.
- Oral antihistamines help with itching and sleep. Ask a pharmacist which one suits you.
- Many home remedies are unproven, and some (like undiluted tea tree oil or vinegar) can irritate skin.
- Infection, large blisters, fever or swelling of the face need a doctor.
- Bites will keep appearing until the bed bugs are professionally treated.
Which Treatment Do You Need?
Start by matching your bites to the right level of care. Most people fall into the first box.
How to Treat Bed Bug Bites, Step by Step
This routine follows guidance from the American Academy of Dermatology and major medical centers. It works for the large majority of bed bug bites.
- Wash the bites with soap and water. Use mild soap and cool or lukewarm water. This cleans away saliva and bacteria, lowers the chance of infection and often calms the itch. Pat dry gently.
- Cool the skin. Hold a cold compress or an ice pack wrapped in a clean cloth on the bites for 10 to 15 minutes. Repeat a few times a day to reduce swelling.
- Apply an anti-itch cream or lotion. Over-the-counter hydrocortisone cream reduces redness and swelling. Calamine lotion soothes and dries. Use a thin layer and follow the label.
- Take an oral antihistamine if needed. If you have many bites or the itch keeps you awake, an antihistamine tablet can help. Ask a pharmacist which one is safe for you and whether it causes drowsiness.
- Keep your hands off. Do not scratch, pick or pop blisters. Keep nails short. Cover bites loosely with a bandage if you scratch in your sleep.
- Watch the bites for a few days. Most improve within a week. Growing redness, warmth, pus, fever or bites that are not better after 2 weeks need a doctor.

Home Remedies for Bed Bug Bites: What Works and What to Skip
You will find dozens of “natural cures” online. Some are soothing and low risk. Others have little evidence and can irritate already inflamed skin. Here is an honest look.
| Remedy | What it may do | Our take |
|---|---|---|
| Cold compress or ice | Reduces swelling and itch | Helpful |
| Colloidal oatmeal bath | Soothes large areas of itchy skin | Helpful |
| Aloe vera gel | Cooling and soothing, limited proof for bites | Maybe |
| Baking soda paste | Popular, but little evidence, can dry or irritate | Maybe |
| Honey | Some antibacterial action, messy and sticky in bed | Maybe |
| Tea tree or other essential oils | Can cause skin irritation or allergy, especially undiluted | Skip |
| Apple cider vinegar | Acidic, can sting and burn scratched skin | Skip |
| Rubbing alcohol or bleach | Dries and damages skin, bleach is unsafe on skin | Skip |
If a home remedy stings, burns or makes the redness spread, wash it off and stop using it. When in doubt, stick with soap and water, a cold compress and a product made for itchy skin.
How Bed Bug Bites Heal
Knowing what normal healing looks like helps you spot a problem early. For a typical person with a few bites, it goes like this:
Red, raised, itchy welts. This is when treatment helps most.
Swelling goes down and itching eases. Bumps flatten.
Marks fade to pink or light brown and disappear.
Scratched bites may leave dark spots that fade slowly.
Want to compare your bites with what is typical at each stage? See our guide on what bed bug bites look like, and if itching is the main problem, read why bed bug bites itch and how to stop it.
How to prevent dark marks and scars
- Do not scratch or pick. This is the number one cause of lasting marks.
- Treat the itch early so you are less tempted to scratch.
- Keep healing skin moisturized with a plain, fragrance-free moisturizer.
- Protect healing marks from the sun with clothing or sunscreen, since sun can darken them.
- Ask a dermatologist about dark spots that last more than a few months.
Treating Bed Bug Bites in Children, During Pregnancy and on Darker Skin
Babies and children: start with washing and cool compresses, and keep their nails short. Check with your pediatrician or pharmacist before using any cream or antihistamine, because many products have age limits. Dress kids in light, long-sleeved pajamas to reduce scratching at night, and call the doctor if a child has many bites, a fever or bites that look infected.
During pregnancy or breastfeeding: soap and water, cool compresses and oatmeal baths are low-risk first steps. Talk to your doctor, midwife or pharmacist before using hydrocortisone cream or taking an antihistamine, so they can suggest an option that is right for you.
Brown and Black skin: bites may look purple, dark brown or gray instead of red, and they are more likely to leave dark spots (post-inflammatory hyperpigmentation). Treating the itch early and not scratching is especially important. Use sun protection on healing marks, and see a dermatologist if dark spots last for months.
When to See a Doctor for Bed Bug Bites
Tick any statement that applies. If even one is checked, contact a doctor or urgent care.
Emergency: call 911 or get emergency care right away for trouble breathing, swelling of the face, lips, tongue or throat, a racing heart or dizziness after bites.
A doctor may prescribe a stronger steroid cream, a prescription antihistamine, or an antibiotic if the skin is infected. They can also rule out look-alike problems such as scabies, flea bites, hives or a skin infection.

No cream will keep bed bugs away. As long as they live in your mattress, bed frame or furniture, you will keep getting bitten. Store-bought foggers rarely work and can spread bed bugs to other rooms. Our licensed technicians use proven methods to clear an infestation. Not sure what you are seeing? Our guide on what a bed bug looks like helps you confirm it.
K9 inspectionTrained dogs find live bugs and eggs, even in early infestations.
Heat treatmentRooms heated to about 120°F or more to kill all life stages, often in 1 day.
Chemical treatmentTargeted products in cracks and seams, usually 2 to 3 visits.
Renting in California? Tell your landlord or property manager in writing. Under California Civil Code sections 1954.600 to 1954.605 (AB 551), landlords must share bed bug information and inspection results, and tenants who report bed bugs are protected from retaliation.
Frequently Asked Questions
How do you treat bed bug bites?
Wash the bites with soap and water, apply a cold compress, then use an over-the-counter hydrocortisone cream or calamine lotion. An oral antihistamine can help with strong itching. Avoid scratching and watch for signs of infection. Most bites heal in 1 to 2 weeks.
What is the best thing to put on bed bug bites?
For most people, a thin layer of over-the-counter hydrocortisone cream after washing and cooling the skin works best for red, itchy welts. Calamine lotion is a good option for milder itch. Ask a pharmacist if you are unsure what is right for you.
How do you get rid of bed bug bites fast?
There is no instant cure, but you can speed healing by washing the bites, cooling them several times a day, using an anti-itch cream early and not scratching. Scratching is the main reason bites last longer and leave marks.
Do bed bug bites need antibiotics?
No, not usually. Antibiotics are only needed if a bite becomes infected, for example if it gets hot, painful, swollen, oozes pus or you develop a fever. A doctor decides whether you need them.
Can I use tea tree oil or vinegar on bed bug bites?
It is better to skip them. Undiluted essential oils can cause skin irritation or allergic reactions, and vinegar can sting and burn scratched skin. Soap and water, a cold compress and a product made for itchy skin are safer choices.
How long do bed bug bites take to heal?
Most bed bug bites heal within 1 to 2 weeks. Scratched or infected bites can take longer, and dark marks may fade over several weeks or months, especially on darker skin.
How should I treat bed bug bites on a baby or child?
Wash the bites, use cool compresses and keep nails short. Talk to a pediatrician or pharmacist before using any cream or antihistamine, and see a doctor if a child has many bites, a fever or bites that look infected.
Will treating the bites get rid of bed bugs?
No. Bite treatments only help your skin. To stop new bites, the bed bugs in your home need to be inspected and treated by a licensed pest control operator.
