Many types of insect bites and stings do not require a visit to a medical professional. However, patients whose symptoms persist, or who suspect they have had an allergic reaction to a bite or sting, should consult a physician, such as a dermatologist (physician who specializes in the treatment of skin, hair and nails).

To determine whether a bite or sting is responsible for prolonged symptoms, or whether an allergic reaction has occurred, a physician may conduct a physical examination and collect the patient's medical history, including a list of medications. Physicians may look at the pattern and location of bites to help identify the creature responsible for them.

Physicians may also perform an allergy skin test to pinpoint the source of the bite or sting. This is usually unnecessary; moreover, it carries the small risk that the patient may have an anaphylactic (allergic) reaction to the testing.
