Both mice and rats drink water as we do, and they need at least some food to make it through the day. But they can do something we can’t; they can get enough water from their food sources to survive long over a month. 

They can even survive with minimal food, just like house mice can go weeks without water. Rats, too, can survive the days with minimal food, as long as there is enough moisture in their food source. 


Keeping your house clean is paramount to avoiding a mouse infestation. 

Mice live without food for two to four days before succumbing to death, so there are many other methods you can use to begin attacking your mouse problem.

Once you have discovered rodents in your home, the best thing you can do is to call a professional for a thorough evaluation and an experienced recommendation.
