How Long can Mice go Without Food and Water?

When you see a mouse dart across your room, do you experience a fight or flight response? Whichever direction you go, when the moment passes, the next thought usually re-aligns the fight and flight responders: the food!

The presence of mice invariably indicates they are about to get into food or they have already found it. In your efforts to check the cupboards for infiltration, have you stopped to wonder how long mice can go without food or water?

How long can mice go without water?

Even though mice are dependent upon water for survival, the ways they can go about taking water in can be either direct or indirect.

Direct water

Mice can get direct water from streams, lakes, puddles, or other natural water sources in the wild. In your home, they can get that from water left behind in sinks, condensation around pipes in the walls, water in drains, or often overlooked sources such as pet water dishes.

Indirect water

Believe it or not, mice can go a month or more without directly consuming water. There usual mode of hydration is extracting water from the food they consume. Even foods that seem dry enough to us to warrant chasing it with a glass of water will have enough water to sustain a mouse.

How long can mice go with out food?

Mice are much more dependent upon food than water. They can only go 2-4 days without food of some sort. Keep in mind that this does not mean they need to sit down to a full fest. Mice like to nibble. They will likely eat a morsel or two and then maybe take a few for the road and be just fine. Find more details on what mice like to eat here.

Wild vs home

The amount of time mice can survive without food will depend a lot on the environmental conditions. For example, a mouse in the wild in cold fall temperatures having to sprint from one hiding place to another avoid predators will have high energy needs. While on the other hand, mice cozied inside of a predator free residence with a plethora of food close by will need far less energy.

Starving them out

Once you have cleaned up scattered crumbs and sealed all food containers, can you be confident in a 2-4 day waiting game? Unfortunately, the answer is no. If mice have access to water instead of food, they can extend their survival time beyond the normal range. Most of our homes have more than enough water for mice in this regard.

Beyond the above survival mode, mice have other means of collecting food. Oftentimes, they will have at least a small store of food in some difficult or impossible to reach (by humans at least) places. In addition to storing food, they can also feed off of things such as live or dead insects, underground fungus, seeds, or even their feces.

Bringing it together

Food control is key to controlling mice, but is not the only answer. A constant supply of food can be the source for population expansion sustainment. Once food is protected, the next step is to put together trapping and/or baiting measures to take care of the mice at hand. Finally, no rodent control is complete without blocking off the potential entry points.

Did You Ever Wonder, "How Long Can Mice Live Without Food and Water?"

There are many methods for eradicating a mouse infestation, ranging from baited traps to electronic deterrents to all-natural products. But preventing them from getting the food and water they need can certainly play a role in getting rid of your unwelcome rodent boarders.

The truth is, it’s not as easy as you think to get rid of mice by means of starvation or dehydration. They are very resilient animals, as most pests are. And they can wait out a “famine” for longer than you may realize is possible.

That said, it is possible to deprive mice of the food and water they need, in sufficient quantities, so as to assist in mouse control (though this is seldom a solution by itself. )

    • Can They Survive Their Whole Lives Without Drinking Water?


There are many facts about mice that most people are completely unaware of. One of them is this: mice can only live 2 to 4 days without consuming at least some food.

Mice can only live a few days without food.

Mice get most of their moisture (water) from the food they eat, typically. That means that they can only survive as long without food as most animals (and people) can go without water – a few days.

Mice tend to nibble little bits of food frequently, and they can get into places where food is stored through even penny-sized holes. You often won’t even be aware of what kind of food they are eating or where their food supply is located.

Also realize that even a small store of food, or just crumbs lying around on your floors, can last a long time and keep mice alive and well.

However, here are some ways to limit if not eliminate your mice’s food supply:

  • Sealing off all known potential mouse food sources.
  • Keep your kitchen floor and whole house clean, free of food crumbs.
  • Exterminate insect pests in your home that mice might eat.
  • Don’t leave the dog or cat bowl out full of food – mice will eat it!


Rather than banking all you hopes on dehydrating (or starving) your mice, you need to find out how to kill mice or at least how to get rid of mice.

Understand that while mice can only go a few days without food (they’re not into fasting), they can go literally months without taking a single drink of water.

But mice will certainly take a drink when they can. And if you eliminate food but leave water readily available, they’ll drink the water to survive. So even though the effects won’t be overwhelming, do your best to eliminate mouse’s water supplies – it helps at least a little at least, in conjunction with eliminating their food supplies.

What about baby mice?
Baby mice, called “pups, ” drink the milk of their mother for the first 2 weeks of their lives. By three weeks, they are roaming about outside the nest in search of their own food. But mama mouse needs more food/water during pregnancy and while caring for young – and tightening their food supply will make more difficult for mice to maintain a booming population.

Here are some ways to deprive your mice of water:

  • Don’t leave water out in a dog or cat dish.
  • Don’t leave standing water in sinks or tubs.
  • Keep your indoor air dry with a dehumidifier or other method. This cuts down on “drinkable” condensation.
  • Make sure the crawl space, basement, and areas just outside the home are free of standing water or puddles.

But truth be known, you can’t easily kill mice by trying to eliminate food and water. You need to combine that with other methods.

Here is a three-step plan to do that:

  1. Reduce/eliminate food and water supplies as mentioned above in this article.
  2. Set up traps with food mice can’t resist (like peanut butter or cream cheese) – this forces mice to eat the bait and/or poisoned food.
  3. After your mouse supply seems to have petered out, use electronic and natural mouse deterrents to keep them out. And seal off any known entry points.

Can They Survive Their Whole Lives Without Drinking Water?

With literally no food and water, mice will either die or leave your premises in search of sustenance. As long as they have plenty of food/water in you house, they will stay there for life.

Click this link for an answer to the question “How long do mice live?” But understand, they will live up to four times longer in ideal conditions, such as in your food and water rich home!

While it is unlikely that a mouse would go its entire life without taking a drink of water, it is certainly possible. As long as the animal is getting enough moisture (water, after all) from its food, it can go without water. It’s would be like humans surviving on watermelons and grapes and never drinking “actual water.”

Thus, mice can live a long while without water and only a short while without food. Targeting their food/water supply is a good component to an anti-mouse strategy, but it won’t likely work alone. Combine it with other methods, however, and you enhance the overall effectiveness.

Factors affecting the life of rodents

The peculiarity of the digestive system of mice is such that the animals do not tolerate hunger well, they eat 5 times a day, every day they need to drink at least 15 ml of water. Such a "brutal" appetite of a small creature is associated with an accelerated metabolism. This factor is genetically determined and affects life expectancy. Under the most favorable conditions, a mouse cannot live longer than 5 years. The following factors reduce this duration:

  • Nutrition. A pet is provided with regular, nutritious food by its owner. In the wild, the little mouse takes care of itself. And it is not always possible to get a balanced diet. Malnutrition shortens the lifespan of mice. In the wild, in a relatively favorable environment, the animal reaches the age of 3 years.
  • Reproduction of offspring. The mouse becomes a sexually mature individual 20 days after its birth. Pregnancy lasts about the same. Each litter has 3 to 11 cubs. 18 days after giving birth, the female is again ready for fertilization. However, the life cycle of the animal is affected by the number of pregnancies per year, the number of cubs, and the state of health of the female. In the wild, a mouse reproduces a maximum of 3 offspring per year. The process is activated in the summer. An increase in this indicator significantly weakens the health of the mouse.
  • Living conditions. Mice adapt well to any environment, tolerate heat and cold relatively well, and live everywhere. All this is due to the accelerated metabolism. However, the period of life in nature is influenced by climatic factors, the ability to equip comfortable housing.
  • Threats and risks. The little rodent has many enemies in the wild - birds, foxes, wolves, dogs, hedgehogs eat mice. There are no less dangers in a person's house - a cat, poison for mice, cage traps, traps. Weather disasters threaten life - flood, fire, frost, early frosts.
Lifestyle of mice

Taking into account all factors, scientists have established a life span of 5 years for mice in a domestic environment as a pet, 3 years in the wild. Since favorable conditions in the natural habitat are rarely established, the average life expectancy of mice is only 1 year.

Influence of nutrition

It is recommended to give your pet a ready-made balanced food. Since the mouse must eat per day:

  • greens - 6 g;
  • grain - 12 g;
  • succulent food - 3 g;
  • cereals - 3 g;
  • meal, including bone meal - 0.3 g;
  • fish oil - 0.1 g;
  • milk - 10 g;
  • salt - 0.1 g;
  • bread - 1.8 g;
  • fodder yeast - 0. 2 g.

Nuts, seeds are given periodically. Abuse of these products leads to obesity.
Mouse food
The mouse is called an omnivore. It is almost impossible to leave her without food. To replenish their energy, mice eat everything they can gnaw. With the threat of hunger in the wild, rodents move closer to a person's house. You can always find food there. Assuming that the most unfavorable conditions have arisen, the mouse can live without food for about 10 days.


It is much more dangerous for an animal to be without water. In the absence of liquid in the wild, the mouse eats the succulent parts of the plant. A pet closed in a cage, deprived of water, finds itself in much worse conditions. How long an animal can survive without liquid is also interesting. The mouse lives without food and water for no more than 3 days.

Threat to life

To catch pests, a person resorts to different methods, methods. Traps are ready to kill the mouse immediately or severely cripple. As a result, the animal dies within a day. The traps leave mice unscathed, as long as it doesn't involve a modern adhesive backing.
