Immediately wash the bite with soap and running water, apply an antiseptic, and cover it with a clean dressing. Then contact a healthcare professional for evaluation of infection risk and tetanus vaccination status.
What should you do if bitten by a mouse? - in detail
If a mouse bites you, begin by applying direct pressure with a clean cloth or sterile gauze to stop any bleeding. After the bleeding subsides, rinse the puncture thoroughly with running water for at least one minute, then wash the area with mild soap. Pat the skin dry and cover the wound with a sterile, non‑adhesive dressing.
Next, evaluate the need for professional medical care. Seek immediate attention if any of the following are present:
- Deep penetration or jagged edges
- Signs of infection (redness, swelling, warmth, pus)
- Persistent pain or numbness
- Uncertainty about the mouse’s health status
- Personal history of tetanus, immunocompromised condition, or allergy to rodent saliva
A healthcare provider may prescribe antibiotics to prevent bacterial infection, such as Staphylococcus aureus or Pasteurella species, and administer a tetanus booster if your immunization is outdated. Although rodents are rarely carriers of rabies, inform the clinician about the animal’s environment; they will decide if rabies prophylaxis is warranted.
Observe the bite site over the next 24–48 hours. Record any increase in size, spreading redness, fever, or unusual discharge. Report these changes promptly to a medical professional.
To reduce the risk of future incidents, eliminate rodent access to food and shelter, seal entry points, and maintain a clean living area. Use traps or professional pest control when infestations are identified.
