Do rats or mice bite?

Rodents, including rats and mice, are known for their sharp teeth but rarely bite people. Healthy rats and mice are typically not aggressive and will often scamper away rather than confront a human. However, bites can occur under certain conditions, such as when the rodent feels threatened or cornered. Here are the risks, symptoms, and ways you can prevent rat and mouse bites.

What Happens if a Rat Bites You?

Rat bites are uncommon but can happen if the rodent feels cornered or in danger. This often occurs when someone attempts to handle or cage the rat or if they come across one in the wild.

Signs & Symptoms of a Rat Bite

Bites from rodents can cause the following symptoms:

  • Redness and swelling around the site of the bite.
  • Mild pain around the site of the bite.
  • If infected, the bite may become filled with pus.

In more severe cases, a bacterial infection such as rat-bite fever (RBF) may develop. Caused by Streptobacillus moniliformis or Spirillum, this disease can result in symptoms like:

  • Muscle aches and joint pain
  • Fever and vomiting
  • Rashes or ulcers around the bite site

If you suspect you’ve been bitten by a rat, it’s important to always seek medical attention, regardless of your symptoms.

Do Rats Attack Humans?

Rats are not naturally aggressive toward humans, but they may attack if provoked. A rat bite will typically only happen when the rodent feels cornered or in danger. For example, a rat might bite if someone tries to trap or handle it. 

What Does a Rat Bite Look Like?

Rat bites can be either shallow or deep and may draw blood. They can cause pain, redness, and swelling around the bite area. Additional symptoms, such as pus or ulcers, may appear if the wound becomes infected.

What Happens if a Mouse Bites You?

While mice are generally less aggressive than rats, bites can still happen, particularly if the mouse feels trapped or frightened.

Signs & Symptoms of a Mouse Bite

Mouse bites often present with mild symptoms, such as:

  • Redness or irritation at the bite site
  • A small puncture wound or scratch
  • Possible swelling or rash

In rare cases, diseases like lymphocytic choriomeningitis (LCM) may result from a mouse bite, with symptoms including fever, joint pain, and flu-like effects.

Do Mice Attack Humans?

Mice are less likely to bite a person or animal than rats are. However, bites can occur during a mouse infestation or when handling pet mice. These bites may pose risks if the mouse is infected with a disease.

What Does a Mouse Bite Look Like?

Mouse bites are usually smaller and less severe than rat bites. They can cause pain, redness, and swelling, though they are less likely to become infected if cleaned promptly.

Do All Rodents Bite?

Not all rodents are known to bite. Like with any pest, rats and mice can bite if they are under extreme duress. In general, it’s best not to risk it. This means avoiding approaching a nuisance rat or mouse that you find in your home. Instead, always contact your local rodent exterminators to help get rid of the rodents for you.
