Most insect bites don’t need antibiotics, since redness, swelling and itching are usually just your skin’s normal reaction rather than a true infection. NICE guidance is clear that antibiotics for an insect bite should only be used once there are genuine signs of infection, not simply because a bite looks red or feels itchy. Knowing the difference helps you treat bites safely and avoid unnecessary antibiotics.
What Are the Signs of an Infected Insect Bite?
An infected insect bite will usually become more red, swollen and painful over time, rather than gradually settling down.
Signs to look out for include:
- Redness or swelling that spreads or worsens after 48 hours.
- Increasing pain, heat or tenderness around the bite.
- Pus, discharge or a yellow crust forming on the skin.
- A fever or feeling generally unwell.
Do You Need Antibiotics for an Insect Bite?
You only need antibiotics for an insect bite when there are genuine signs of infection. Redness, swelling or itching on their own don’t necessarily mean the bite is infected.
NICE’s guideline on insect bites and stings confirms that most bites do not need antibiotics. A reaction that appears quickly is more likely to be inflammatory or allergic than an infection. Antibiotics are appropriate when there are clear signs that an infection has developed.
When Are Insect Bite Antibiotics Actually Necessary?
Antibiotics for an insect bite are generally only needed when a bacterial infection has developed. This can happen after scratching damages the skin and allows bacteria to get in.
You should seek advice if you have:
- Symptoms and signs of infection, treated in line with NICE’s cellulitis guidance.
- Severe pain that seems out of proportion to the bite, which can be a sign of a more serious infection.
- Symptoms that spread rapidly or come with a fever.
How Can You Manage Insect Bite Swelling and Itching at Home?
Most insect bite swelling and itching improve within a few days and can be managed with simple self-care. You can:
- Wash the area with soap and water.
- Apply a cold compress to reduce swelling.
- Take an antihistamine or use a soothing cream for itching.
- Try not to scratch the bite, as this can increase the risk of infection.
What Should You Do About an Infected Mosquito Bite or Other Infected Bite?
If a mosquito bite or another insect bite starts to look infected, speak to a pharmacist rather than simply waiting for it to clear up on its own.
Pharmacists can assess an infected insect bite and, where appropriate, supply the same antibiotics as a GP through the NHS Pharmacy First service, without you needing a separate GP appointment.

Frequently Asked Questions
Do you need antibiotics for an insect bite?
No, not usually. Most insect bites settle on their own within a few days, and antibiotics are only needed if there are clear signs of infection, such as spreading redness or pus.
What are the main insect bite infection symptoms?
The main signs are worsening redness or swelling after 48 hours, increasing pain or warmth, pus or discharge, and feeling feverish or generally unwell.
How long does normal insect bite swelling last?
Ordinary swelling and redness usually improve within a few days and settle fully within one to two weeks, without needing antibiotics.
Can a pharmacist prescribe antibiotics for an infected insect bite?
Yes, pharmacists can assess an infected insect bite through the NHS Pharmacy First service and supply the same antibiotics a GP would, if the infection needs treating.
Are mosquito bites more likely to get infected than other bites?
An infected mosquito bite usually results from scratching rather than the bite itself, so keeping the area clean and avoiding scratching lowers the risk regardless of the insect involved.
