Most of the time, they’re harmless and go away with a little home care, but sometimes a bite or sting can lead to a serious reaction. Here’s how to tell the difference between a minor nuisance and a medical emergency.

Common Reactions to Bites and Stings

Most insect bites and stings cause mild symptoms like:

• Redness and swelling at the site

• Itching or mild pain

• Localized warmth or a small raised bump

These typically improve within a few days with over-the-counter remedies, antihistamines, or cool compresses.

Signs It Could Be Serious

Seek emergency care if you or someone else experiences:

• Trouble breathing or swallowing

• Swelling of the lips, tongue, throat, or face

• Dizziness, confusion, or fainting

• Rapid heartbeat or chest tightness

• Nausea, vomiting, or widespread hives

• A bite that becomes increasingly red, swollen, or painful over time (could be infected)

• A known allergy to insect venom and no access to epinephrine

High-Risk Insects to Watch For

• Bees, wasps, and hornets (risk of anaphylaxis)

• Fire ants (can cause painful stings and allergic reactions)

• Spiders (brown recluse and black widow bites can lead to severe tissue damage or systemic symptoms)

• Ticks (risk of Lyme disease or other infections)

What You Can Do at Home

• Wash the area with soap and water

• Apply a cold compress to reduce swelling

• Take an over-the-counter antihistamine or pain reliever

• Monitor the site for signs of infection (spreading redness, pus, fever)

Why the ER May Be Needed

If there’s any sign of a systemic allergic reaction or the bite appears to be worsening quickly, it’s best to head to the ER. At Ally Medical Emergency Room, we provide fast treatment for allergic reactions, infections, and severe symptoms, including IV medications and monitoring, if needed.
