Biting insects such as midges and mosquitoes are more likely to cause local allergic reactions, such as redness and/or swelling, but can sometimes cause allergic reactions.
A severe reaction to mosquito bites can cause: A large, swollen, inflamed area. A hive-like rash.
When an insect bites, it releases saliva that can cause the skin around the bite to become red, swollen and itchy. The venom from a sting often also causes a swollen, itchy, red mark (a weal) to form on the skin. This can be painful, but it's harmless in most cases.
Bites of mosquitoes, chiggers (harvest mites), fleas, and bedbugs usually cause itchy, red bumps. Painful Insect Bites. Bites of horseflies, deer flies, and gnats usually cause a painful, red bump. Fire ants, harvester ants, blister beetles, and centipedes also cause a painful, red bump.
Typically, a spider bite looks like any other bug bite — a red, inflamed, sometimes itchy or painful bump on your skin — and may even go unnoticed. Harmless spider bites usually don't produce any other symptoms.
If any redness, swelling or hardening of the skin around the bite gets worse over 24 to 72 hours, be sure to get into the doctor as soon as possible. “The most concerning symptoms would be those of a severe allergic reaction, such as shortness of breath, facial swelling or difficulty swallowing,” Coates said.
You should see your GP if you've been bitten or stung and there's a lot of swelling and blistering or if there's pus, which indicates an infection. Dial 999 and ask for an ambulance if you experience any of these symptoms after a bite or sting: wheezing or difficulty breathing. nausea, vomiting or diarrhoea.
Apply a cloth dampened with cold water or filled with ice to the area of the bite or sting for 10 to 20 minutes. This helps reduce pain and swelling. If the injury is on an arm or leg, raise it. Apply to the affected area calamine lotion, baking soda paste, or 0.5% or 1% hydrocortisone cream.
Both Benadryl (diphenhydramine) tablets and hydrocortisone creams can help with bug bites. Benadryl tablets are best taken before heading outdoors to prevent symptoms; however, it may be better to try a newer generation oral antihistamine such as Curist Allergy Relief (levocetirizine) if Benadryl makes you sleepy.
If you scratch too much and break the skin open, a bacterial skin infection can develop, which will require a visit to urgent care or UnityPoint Clinic - Express,” Becker says. Instead of scratching, apply an over-the-counter hydrocortisone cream or calamine lotion to help take away the itch.

Signs of cellulitis include: Redness, swelling, warmth or tenderness around the bite area. Red streaks that shoot out from the bite area.
Now, a new study in mice suggests that your immune system could react to these allergy-inducing proteins for up to a week, potentially explaining why an itchy bite lingers so long.
Rather than relieving the itching, scratching an already inflamed area increases inflammation. This makes the area even itchier. Scratching may also increase the risk of infection if it breaks the skin. If the area becomes infected, it will be much itchier and will take longer to heal.
Insects that can trigger allergic reactions include mosquitos, kissing bugs, bees, wasps and fire ants. A typical reaction for those who are not allergic may include pain, swelling and redness that's confined to the sting or bite area. But if you're having an allergic reaction, the symptoms may be more severe.
