Some people have an allergic reaction when they are bitten by insects like mosquitoes. The venom or saliva released by the insect can cause swelling, itchiness and irritation.
In the UK, insects that bite include:
- midges
- mosquitoes
- fleas
- bedbugs
- ticks
The symptoms of insect bites can vary depending on the type of insect and the sensitivity of the person who is bitten. For example, some people may have a small, itchy lump after they are bitten, which only lasts for a few hours. Others may develop a more serious reaction, such as blistering and a number of itchy, red lumps.
Bite or sting?
As well as insects that bite, some insects sting and inject venom into the wound. In the UK, insects that sting include:
- bees (honeybees and bumblebees)
- wasps
- hornets
