What are the symptoms of an infected insect bite?

Most insect bites are painful at the site of the bite or sting, and you may find you’ve got a small swollen, itchy lump too. If you’re mildly allergic, you might also find the area around the bite is also more swollen.

Symptoms of an infected bug bite may include

  • Swelling
  • Pain or tenderness
  • Fluid coming from the area
  • Red lines or ‘tracks’ spreading out from the bite site
  • A high temperature and feeling generally unwell.

How do I treat an infected insect bite?

Treatment at home

  • Press an ice pack wrapped in a clean cloth on the bite for around 20 minutes to reduce swelling
  • Take painkillers
  • Take antihistamines if it’s very itchy and swollen
  • Try a hydrocortisone cream – this also helps reduce itching and swelling
  • Ultimately if you think it’s infected, the best thing to do is to speak to one of our pharmacists.
