I get itchy when I get bit by a mosquito. I wanted to know why, so I started doing some research online. There were lots of websites with information about mosquitoes and mosquito bites, but not much about what bites cause hives. A few websites said that stinging insects bite cause hives, but no one seemed to know. Can you believe it? After all, it only makes sense, right? So anyway…
So the question is: what insect bites cause hives? Well, you should know that the list of insects that can cause an allergic reaction in humans is quite long. Most commonly these are fleas, bedbugs, and mosquitos.
What Insect Bites Cause Hives?
Hives are a condition that causes the skin to swell and become itchy. It’s usually caused by an allergy, but it can also be caused by insect bites.
Here are some common insect bites that cause hives:
- Fire ants
Not all insect bites cause hives, but some of the most common culprits are mosquito bites and flea bites.
Mosquito bites are painful, itchy bumps that usually appear within a few hours of being bitten. They often become red, swollen, and sensitive to touch. Mosquito bites can also cause swelling in your lymph nodes, which may be accompanied by fever and chills.
Flea bites often cause similar symptoms to mosquito bites: redness around the bite site, swelling in the lymph nodes, and itching. However, flea bites tend to have a central point of irritation that’s surrounded by redness and swelling instead of looking like a smooth bump or rash.
Hives are caused by an immune response that causes your body to produce histamine (an inflammatory agent). When you’re bitten by an insect that carries the protein responsible for causing hives (called the “allergen”), your immune system produces antibodies called immunoglobulin E (IgE) that recognize this protein as an invader. These antibodies bind to mast cells throughout your body and release histamine into your bloodstream which causes symptoms like itching, flushing, swelling, etc.
