About Infected Insect Bites
An insect bite or sting can become infected if you’ve been scratching the bite and bacteria get into the broken skin. Warm, humid weather and bites picked up while travelling can make infection more common, especially if you react strongly to the bite.
The bite area is also more at risk if the bite area gets dirty, becomes irritated, or you’ve been exposed to insects or bacteria your body isn’t used to – particularly ones not found in the UK.
Symptoms of an Infected Insect Bite
Wondering how to tell if an insect bite is infected? Look out for these signs:
- The area feels hot, painful or increasingly swollen
- Redness is spreading around the bite
- Pus or fluid is leaking from the skin
- You feel unwell or have a fever
If you notice any of these symptoms, you may need treatment to clear the infection. The right advice and treatment depend on the severity of the bite and its location. Some mild bites can be managed with over-the-counter creams, while others may need prescription treatment.
Infected Insect Bite Treatment
Mild Bites
For mild bites with itching, redness or swelling, treatment options include:
- Antihistamine tablets like Loratadine can help reduce the body’s reaction to the bite
- Mild steroid creams like Hydrocortisone or Eumovate can ease inflammation and itching
- Germolene provides antiseptic protection to help prevent infection
- Calamine lotion, E45 cream, or E45 Itch Relief can soothe irritated skin
These are often suitable for bites on the arms, legs or torso that aren’t showing signs of infection.
Infected Bites
If the bite is becoming more painful, warm, swollen or starts leaking pus, it may be infected and you may need antibiotics such as Fucidin cream.
How to Prevent Infected Insect Bites
Avoiding insect bites in the first place can help stop the cycle of itching, scratching and infection, especially if you’re heading outdoors or travelling abroad.
To reduce the risk:
- Use Jungle Formula Extra Strong spray or lotion, or other high-strength repellents on exposed skin
- Wear long sleeves and trousers in areas with midges or mosquitoes
- Avoid using scented body products that attract insects
- Keep windows and doors closed or use nets in the evening when insects are most active
Using a repellent regularly, especially in the evenings or when travelling, is one of the best ways to avoid bites that could become infected.
