How do insect bites get infected?

Insect bites usually clear up on their own, but in some cases they can get infected. This can happen when bacteria are introduced to the area, often by scratching. Bites in areas that rub against clothing or are in hard-to-reach spots, like the ankles or behind the knees, are more likely to become infected too.

In this blog post, we explore what happens when an insect bite gets infected and share some simple, practical tips to help you keep bites clean and avoid an infection.

What happens when an insect bite gets infected?

If it’s been a few days and your insect bite is looking worse rather than better, that could mean it has become infected.

Signs of an infected bite include redness around the area, swelling or soreness, warmth in the affected area or pus or fluids leaking from the wound.

In more serious cases, you may get swollen glands or a high temperature. The bite might even blister or turn into a sore that just won’t heal.

If you notice any of these changes, it’s your body’s way of telling you that the bite needs extra care.

How to stop insect bites getting infected

Insect bites happen, especially if you spend a lot of time outdoors. If you do get bitten, don’t panic; there are ways to help reduce the risk of an infection taking hold. Taking a little extra care bite right away after being bitten can help the bite to heal faster and may reduce your risk of painful symptoms.

Here are some simple tips to treat insect bites, keep them clean and stop them from getting infected in the first place.

Wash the affected area

As soon as you notice a bite, it is good practice to gently wash the area with antibacterial soap and water. This helps to remove any dirt or germs from the skin and lowers the risk of infection.

Once clean, pat the area dry with a clean towel. Avoid rubbing, as this can irritate the bite further.

If you’re out and about and don’t have access to running water or soap, then an antiseptic wipe or spray from a first aid kit can serve the same purpose.

Try not to scratch the bite

Itching is one of the most annoying things about insect bites, but scratching can break the skin and let germs in. Whenever you feel like you need to scratch the bite, try to distract yourself or use a soothing cream recommended by your pharmacist.

If you’ve been bitten, it’s a good idea to keep your nails short and clean. That way, if you forget and accidentally scratch, there is less risk of germs entering the skin.

Cover the bite with a plaster or bandage

If you have a bite in a spot that you just can’t stop scratching or it is being rubbed by clothing, you could try covering it with a plaster or a bandage. This creates a barrier to keep germs out. It’s also a simple way to stop children from scratching.

Use an ice pack or cold compress to ease inflammation

If the bite is swollen, red or very itchy, a cold compress or ice pack may help reduce these frustrating symptoms. Wrap some ice in a clean cloth and place it on the bite for 10 to 15 minutes at a time. Remember, never apply ice directly to the skin, as this can cause further pain.

Most insect bites will heal on their own with no problems, but it’s always worth taking a few extra steps to keep your skin healthy and limit the risk of infection. Remembering to carry a first aid kit with you when you venture into nature can be a great help.

If you do notice a bite getting worse or not healing, treatment is available. If you’re worried, speak to your pharmacist for further advice and assistance.
