Infected Insect Bites (NHS)
Infected insect bites occur when bacteria enter the skin through a bite, causing redness, swelling, and sometimes pus. While most insect bites are minor and heal on their own, some can become infected and require treatment. Our pharmacists can assess the severity of your bite and provide advice or treatment to help prevent complications and promote faster healing.
What to consider
-
Infected insect bites are caused when bacteria enter the skin through a bite or scratch. This can happen if the bite is scratched excessively, if the skin is broken, or if bacteria are present on the surface of the skin. Common bacteria involved include Staphylococcus aureus and Streptococcus species.
-
Pain or discomfort at the site of the bite or sting
A small, raised, red or swollen lump on the skin
On darker skin tones, the redness may be less visible, but the lump can usually be felt
Multiple bites may appear close together in one area
Mild allergic reactions, such as itching or irritation, can occur
If the bite or sting becomes infected, the area may become more painful, swollen, or warm
Severity of symptoms can vary depending on the type of insect and the person’s sensitivity
