Rodent Bite First Aid – What NOT to do
When providing rodent bite first aid, certain actions can make the injury worse or increase the risk of infection. Avoid these common mistakes to keep yourself or others safe.

- Do not apply ointments, creams, or powders unless advised by a healthcare professional.
- Do not try to suck out the bite or cut the wound open.
Do NOT ignore signs of infection or severe symptoms
If you notice increasing redness, swelling, warmth, pus, or if the person develops fever, chills, or severe pain, seek medical care immediately.
Call 911 or go to the emergency department if the bite causes heavy bleeding that won’t stop, difficulty breathing, severe allergic reactions, or if the person feels faint or confused.
