Insect bites are usually harmless and heal within a few days, but sometimes they can become infected if bacteria enter the skin. This can happen through scratching, broken skin, or improper wound care. Mild infections can be treated effectively with pharmacy-supplied treatments, while more severe cases may require antibiotics.
Symptoms of an Infected Insect Bite
A typical insect bite causes mild redness, swelling, and itching, but an infection can develop if bacteria enter the wound.
Signs of infection include:
Increased pain, swelling, and redness around the bite
Pus or yellowish discharge
Warmth and tenderness in the affected area
Red streaks spreading from the bite (this may indicate a more serious infection)
Swollen lymph nodes near the bite
Fever, chills, or feeling unwell in severe cases
If the infection worsens, spreads, or does not improve with treatment, medical attention may be needed.
Pharmacy Treatment for Infected Insect Bites
A pharmacist can assess symptoms and recommend the appropriate treatment, including:
Antiseptic creams or solutions – To cleanse the area and prevent bacteria from spreading.
Antihistamines – To reduce itching and inflammation, preventing further irritation.
Hydrocortisone cream (1%) – A mild steroid to help reduce swelling and discomfort.
Oral pain relief – To ease pain and inflammation.
Antibiotic creams – If the infection is mild and localised.
Oral antibiotics – For more severe or spreading infections, a pharmacist may recommend oral antibiotics.
How Long Does an Infected Bite Take to Heal?
With proper treatment, most mild infections improve within a few days. However, a more severe infection may take one to two weeks to fully clear, particularly if oral antibiotics are needed.
Preventing Insect Bite Infections
To lower the risk of infection and promote healing:
Do:
✔ Wash the bite area with soap and water as soon as possible
✔ Apply an antiseptic cream or spray to prevent infection
✔ Keep the area clean and dry
✔ Cover larger bites with a plaster or dressing if needed
✔ Trim nails and avoid scratching to prevent bacteria from entering
✔ Use cold compresses to reduce swelling and irritation
Don’t:
✖ Scratch or pick at the bite – this increases the risk of infection
✖ Apply dirty hands or objects to the bite area
✖ Ignore spreading redness, pus, or pain – seek medical advice if symptoms worsen
Avoiding Insect Bites in the Future
To minimise the risk of insect bites and potential infections:
✔ Use insect repellent (containing DEET or picaridin)
✔ Wear long sleeves and trousers in high-risk areas
✔ Avoid stagnant water and heavily wooded areas where insects breed
✔ Keep windows and doors closed or use insect screens
✔ Apply antihistamine creams or tablets quickly if bitten to reduce scratching
A pharmacist can provide expert advice and treatment to help manage infected insect bites and prevent complications.
