Symptoms include pain, swelling, warmth, redness at the site of the sting and itching.

These symptoms arise soon after stings and take several hours to subside. Large localized reactions may result in pronounced swelling, as well as fatigue and nausea, and take a week to clear up.

These symptoms do not cause major medical problems and are usually limited to or are very near the sting site. Secondary bacterial infections. This type of skin infection develops if the sting site is frequently scratched and bacteria are given a suitable condition in which to develop.

Failure to adequately clean, disinfect and medicate sting sites enable infections to occur. Systemic affecting the whole body allergic reactions.

These reactions occur in people or pets that have produced a type of antibody, known as immunoglobulin E, against the same insect venom from a previous sting. Systemic allergic reactions are critical medical issues, but occur in a very small percentage of stings. Symptoms of systemic allergic reactions include swollen red bumps on the skin, flushing of the skin and difficulty breathing due to swelling of the pharynx epiglottis and narrowing of the bronchial passages.

The reactions may vary in severity from mild skin to life-threatening. Anaphylaxis, the most severe immunologic reactions, occur more commonly in males and people less than 20 years of age. The venom also contains proteins that can cause an allergic reaction. For example, stings to the face tend to cause more pronounced reactions and swelling than stings elsewhere on the body.
