Most bug bites are not a medical concern but might require some at-home remedies to relieve itchiness as the bite heals. However, there are some scenarios in which a bug bite is more serious and requires medical attention, either for eventual treatment to prevent infection or in some emergency cases. Signs that a bug bite requires emergency medical attention include dizziness, difficulty breathing or swallowing, being stung or bitten more than 10 times at once, causing you to feel ill, as well as any significant and rapid swelling around the site of the bite. Signs that the bite may be becoming infected include the development of pus around or in the bite, pain, swelling, or redness that increases around the bite, and if your glands are swollen.
