Immediately wash the bite with soap and water, apply an antiseptic, and cover it with a clean dressing. Then consult a healthcare professional for assessment, tetanus prophylaxis, and monitoring for infection or disease.
What should you do after a mouse bite? - in detail
When a mouse punctures the skin, begin by washing the wound with running water and mild soap for at least one minute. Apply gentle pressure with a clean cloth or gauze to stop any bleeding. After the area is clean, cover it with a sterile, non‑adhesive dressing to protect against further contamination.
Next, assess the need for medical attention. Seek professional care if any of the following apply:
- The bite is deep, larger than a pin‑prick, or shows signs of tissue damage.
- The animal was wild, unfamiliar, or possibly diseased.
- The victim has a compromised immune system, diabetes, or circulatory problems.
- There is no up‑to‑date tetanus immunization within the past five years.
A healthcare provider may prescribe antibiotics to prevent bacterial infection, especially because mouse saliva can carry Streptococcus and Staphylococcus species. If tetanus protection is outdated, a booster injection should be administered. Rabies risk from mice is extremely low, but a clinician will evaluate exposure circumstances and advise accordingly.
Observe the bite site for the next 48–72 hours. Note any increase in redness, swelling, warmth, pus formation, or escalating pain. Systemic symptoms such as fever, chills, or malaise also warrant immediate reassessment.
To reduce future incidents, eliminate food sources, seal entry points, and maintain cleanliness in areas where rodents may reside. Regular inspection and pest‑control measures help keep environments safe.
