Do rats or mice bite?

You may have seen the teeth of rats or mice – particularly their large and threatening incisors. They look scary, but it  might help to know that healthy rodents are not known for biting or acting aggressively towards humans. They’d rather scamper away than confront and attack. Of course, you should still know the basics about rat and mouse bites:

  • Rodent bites are rare, but may occur if the rat or mouse feels threatened. It may also happen if the rodent is rabid.
  • Mice are less likely to bite than rats.
  • Rats and mice can transmit diseases through biting. 
  • Rodent bites rarely become infected, but can cause pain, redness and swelling.

What Happens if a Rat Bites You?

Do mice bite? And if they do, what happens?

A rat or mouse bite usually only happens when the rodent feels cornered or in danger. You’re especially at risk if you try to cage the critter, or if you come across a mouse or rat in the wild. Rat bites can be shallow or deep and may draw blood. The main concern with a rodent bite, however, is the risk of contracting a disease. Some deer mice carry Hantavirus, and rat bite victims run the risk of contracting rat-bite fever.

Signs & Symptoms of a Rat Bite

If you believe you’ve been bitten by a rat, you should seek medical attention regardless of your symptoms. Common side effects of rodent bites may include: 

  • Redness and swelling around the site of the bite
  • Mild pain in the area
  • If infected, the bite may fill with pus. 
  • In cases of bacterial infections like rat-bite fever, you may experience muscle aches, joint pain, vomiting, fever, rashes and ulcers.


Do All Rodents Bite?

Not all rodents are outwardly aggressive, and most will usually only bite if they are under extreme duress. Still, if you suspect you have a rat or mouse infestation in your house it’s best not to risk handling it yourself.
