Which home remedies for bug bites are worth using, the first aid that works better than any of them, and the repellent advice that prevents the bite.
Most bites are minor and settle in a few days. The useful question is not which kitchen ingredient to dab on, but what genuinely helps, what to avoid putting on broken skin, and which symptoms mean stop treating and call someone.
This page has been rewritten. The previous version led with essential oils, listed vinegar, turmeric, honey and rubbing alcohol as remedies, and reduced the two most useful things, proper first aid and repellent choice, to a sentence each.
Key Takeaways
- First aid is simple: wash, then ice 10 minutes on, 10 off, then an antihistamine if needed (1).
- Scrape a stinger out with a card edge. Tweezers squeeze more venom in (1).
- We have removed the essential oils. A bite is broken skin (7, 8).
- DEET has no age restriction; some lemon eucalyptus products are not for under-threes (5).
- Breathing trouble or facial swelling is an emergency, not a home remedy situation (1, 3).
What To Actually Do
SaveThis is the sequence MedlinePlus gives for most bites and stings (1):
- Remove a stinger by scraping, using the edge of a credit card or another straight-edged object drawn across the skin. Do not use tweezers, which can squeeze the venom sac and release more venom.
- Wash the site thoroughly with soap and water.
- Ice it. Wrap ice in a cloth, hold it on for 10 minutes, take it off for 10 minutes, and repeat.
- Use an antihistamine or an anti-itch cream if you need more relief.
- Watch it for several days for signs of infection: increasing redness, swelling or pain.
Two things not to do: do not apply a tourniquet, and do not give aspirin or other pain medicine unless a healthcare provider has prescribed it (1).
That is the whole of ordinary bite care. It is unglamorous, and it works better than anything this page used to lead with.
Why it itches
When an insect bites or stings, it leaves saliva or venom under the skin. Your immune system treats it as foreign and reacts, and the redness, swelling and itch are that reaction (2). Scratching breaks the skin further and is how a nuisance bite turns into an infected one.
What We Removed, and Why
| What the page used to recommend | Why it has gone |
|---|---|
| Tea tree, neem, lavender and other essential oils, applied to the bite | A bite is broken skin. Essential oils are a recognised cause of allergic contact dermatitis; in one French series of 42 people sensitised to their own oils, eight needed hospital treatment (7). Fragrance is among the commonest causes of contact allergy generally (8), and NCCIH notes how little rigorous research exists (9) |
| Apple cider vinegar on a cotton ball | No evidence, and the page itself warned it stings broken skin, which is most bites after scratching |
| Turmeric paste, honey, rubbing alcohol | No trial evidence for bites. Rubbing alcohol dries and irritates skin that is already inflamed |
| Baking soda paste | Harmless and traditional. We have kept it mentioned as a comfort measure rather than presenting it as treatment |
The essential oils deserve the most explanation, because they were the first thing this page recommended.
A bite is a small open wound, often scratched open further. Essential oils are a recognised cause of allergic contact dermatitis: in a French study of 42 patients with contact dermatitis caused by oils they were using themselves, eight required hospitalisation, and 71% had positive patch tests to fragrance mix (7). Fragrance is among the most common causes of allergic contact dermatitis generally (8). Putting a concentrated plant oil on inflamed, broken skin risks turning a three-day itch into a three-week rash.
Prevention Is the Real Answer
SaveThe best-supported advice on this page is about not getting bitten, and it is more specific than “wear a repellent”.
| Repellent | What EPA says | Children |
|---|---|---|
| DEET | One of the registered active ingredients EPA evaluates for skin-applied repellents (6) | Approved with no age restriction, and no restriction on the percentage (5) |
| Picaridin | EPA-registered active ingredient (6) | Follow the product label (5) |
| IR3535 | EPA-registered active ingredient (6) | Follow the product label (5) |
| Oil of lemon eucalyptus (OLE) / PMD | EPA-registered active ingredient (6) | Some OLE products should not be used on children under three; check the label (5) |
| Untested botanical oils | Not the same thing as an EPA-registered repellent. Essential oils are a recognised cause of allergic contact dermatitis (7, 8) | Not a substitute |
EPA’s safe-use rules are worth following exactly (5):
- Read the label and follow it for how much to apply.
- Exposed skin and clothing only. Never under clothing.
- Not near eyes or mouth, and sparingly around the ears.
- With children: do not let them handle the product and do not apply it to their hands. Put it on your own hands first, then on the child.
- Wash it off with soap and water once you are back indoors.
Cover up where you can as well: long sleeves and trousers in woods, tall grass and leaf litter. MedlinePlus adds some sensible avoidance rules around bees: skip perfume and dark or floral-patterned clothing in areas with hives, avoid sudden movements near nests, and be careful eating outdoors near sweet drinks and bins (1).
Ticks Are a Different Problem
The previous version mentioned ticks in its first sentence and then never came back to them. They deserve their own note, because the issue is not the itch.
Ticks are parasites related to spiders that feed on blood, and they pick you up in tall grass, leaf litter and shrubs. Certain ticks transmit germs that cause disease, including Lyme disease, alpha-gal syndrome, babesiosis, ehrlichiosis, Rocky Mountain spotted fever and tularemia. You may not feel the bite (4).
So after time in tick country: check your skin, remove any tick promptly, and watch for a rash or flu-like symptoms in the days and weeks afterwards. Flu-like illness following a bite is a reason to see a doctor and to mention the bite, because it changes what they look for.
When It Is an Emergency
Call emergency services immediately if someone who has been bitten or stung has (1, 3):
- Trouble breathing, wheezing or shortness of breath
- Swelling anywhere on the face or in the mouth
- Throat tightness or difficulty swallowing
- Feeling weak, or turning blue
While waiting: keep the person calm, remove rings and anything tight near the area because it may swell, and use their adrenaline auto-injector if they carry one (1).
Anyone who has had a severe whole-body reaction to a sting should be referred to an allergist and given an emergency kit to carry (1).
See a doctor, less urgently, for a bite from a scorpion or a venomous spider, for any bite that keeps spreading or swelling after a few days, for signs of infection, and for flu-like symptoms afterwards (2).

Frequently Asked Questions
What is the fastest way to stop a bug bite itching?
Wash the area with soap and water, then apply ice wrapped in a cloth for 10 minutes on and 10 minutes off, repeating as needed. If that is not enough, an over-the-counter antihistamine or an anti-itch cream is the next step. That is the first aid MedlinePlus actually gives, and it beats anything in the kitchen cupboard.
How do I remove a bee sting?
Scrape it out sideways with the edge of a credit card or something similarly straight. Do not use tweezers, because squeezing the venom sac pushes more venom into the skin. Then wash the area and ice it.
Should I put essential oils on a bite?
We no longer recommend it. A bite is broken skin, and essential oils are a well-documented cause of allergic contact dermatitis, serious enough in one series to put eight of forty-two affected people in hospital.
Which insect repellent should I use?
One registered with the EPA. DEET, picaridin, IR3535 and oil of lemon eucalyptus are all registered active ingredients. DEET is approved for children with no age restriction, while some oil of lemon eucalyptus products should not be used on children under three, so read the label.
When is a bite an emergency?
Trouble breathing or wheezing, swelling of the face or mouth, throat tightness or difficulty swallowing, feeling weak, or turning blue. Call emergency services and use an adrenaline auto-injector if the person has one. Do not wait to see whether it settles.
The Bottom Line
For an ordinary bite, the answer is dull and effective: wash it, ice it for ten minutes at a time, use an antihistamine or anti-itch cream if you need one, and keep an eye out for infection. Scrape a stinger out with a card rather than squeezing it with tweezers. Skip the essential oils, because broken skin is exactly where they cause trouble. Most of the value here is in prevention, so use an EPA-registered repellent, follow the label, and check for ticks after time in long grass. And if breathing or the face is involved, stop reading and call for help.
