Summary: When asking, “What do wild mice eat?” the answer is simple. They eat everything that humans and their domestic pets eat and more. Just look in your pantry after an invasion of mice and you will discover their menu is wide and varied.
There are so many misconceptions pest management professionals hear about rodents. One of the biggest mysteries to non-professionals is what do wild mice eat. We see mice running from trash dumpsters and think, “Yuk! Dirty mice.”
If we could actually see inside that dumpster we would discover something we would think would be entirely out of character for a rat or mouse. We would discover that rodent being very discerning about the food it is dining upon. It's true! No self-respecting rodent would consider eating a morsel of food that
has gone bad. The lowly rodent turns out to be a connoisseur of fresh, clean foods. Funny how that works! We see a mouse or rat and think “filth”, while that same rodent is rejecting anything that fails its freshness test.
When you think about garbage you think of waste or something that has been rejected. In reality, and we all know this, humans are wasteful. We discard containers of food that still have edible residue on the sides. We throw away half-eaten sandwiches because we are full. We toss out a banana because it is too ripe. We don't eat apple cores. We peel potatoes, carrots, apples and so many other foods, throwing perfectly edible items in our garbage. I could easily fill this page with foods that we toss out that is fresh, clean and nutritious.
I think you may be starting to get the picture about what wild mice eat. The answer is right in front of you. They eat everything and anything. Sure, they have their favorites, but mice will nibble on a wide variety of foods, tasting a little here and there. Rats, on the other hand are a lot more picky and suspicious. They will take a small taste of something, and then leave it alone. They do this to see if a new food will make them sick. Once they have digested the sample successfully they will return and gorge on that particular food.
Understanding the differences in what and how mice and rats eat is partially how professionals determine what type animal is infesting a location. Understanding a rodent's eating habits can answer the customer's question, “Is it a rat or a mouse?” People are way more fearful of rats than they are of mice.
When a mouse gains entry into a house, its sensitive nose leads it to the kitchen pantry where a large selection of easily attainable foods is available. The pantry is a supply of nuts, grains, dried fruits and lots of paper for nesting. If the home has pets the bagged pet food becomes a target. Pet food is often kept in the garage where entry under a garage door is fairly easy for a mouse. They can gain entry through a hole the size of a dime which means most
garages are accessible. The protein in dog food is a wonderful food source for mice. It's so good, in fact, that is it not uncommon for mice to build their nests right inside a fifty pound bag of dog chow. Nesting materials supplied by the paper bag and the mouse is surrounded by a food supply. What a life!
Mice are more likely to live inside a house and get along nicely on the foods in the kitchen. Their water requirement is way less than a rat's, with much of their water needs being fulfilled by the moisture contained in the food they eat. A rat needs a more plentiful supply of water, so it needs to nest in an area where water pools on the flood or near other water sources.
So, what do wild mice eat? Anything they can get their little choppers on.

I found two mice in my 50 lb bag of dog food. Gross. Is the food
contaminated now? Should I not feed it to my dog. My instincts say I want
to throw the bag away but wanted to ask the expert first!

Although, generally grain eaters, they will eat nearly anything if the

Twice we have found hal-eaten mice in the glue traps we set. We have no
pets. What is happening?
Ask the Exterminator

Mice are omnivores, meaning they will eat meat, grains or nearly any other
available food source as long as it is fresh. They will attack and eat
another dead mouse.

If the babies have hair you can feed them hamster food, cheese, lettuce or
other veggies. They cannot process the milk humans drink. They are weaned
after 3 to 4 weeks.

Hi Rick - just woke up to the sounds of something that sounded like it was
at my dog's feeding bowl. I could hear the rustling of the dog food etc.
Got up and found a half eaten bowl of food. Not sure if dog ate it earlier
or whatever was at it tonight. How can I fing out what it is without
causing physical harm to the pest? Any suggestions would be great.
Thanks!

Rodents will usually leave behind droppings when they have spent some time
at one location. If not droppings, they will surely urinate.
The easiest way to determine if rodent urine is present is to buy a cheap
blacklight flashlight at Home Depot. The urine is phosphorescent and will
glow under the light.

Hey Rick - you were right! I found droppings within the dog bowl this
morning. So now we know there's a mouse in the house. Can you please let
me know a way I can capture and release the mouse without harming the
little guy.
Thanks!

Weve recently had a mouse (or a family I think) come to stay at our house,
which by the way is an old cottage with little rat runs everywhere. What is
a cheap and effective way to solve this problem?
Any help is gratefully appreciated.
Thankyou sir,
Barry Slaven.

Sorry I forgot to ask this on my previous post:- is it worth spending the
time and effort trying to plaster over all the little gaps in my walls and
skirting where a mouse could fit through, in order to try avoid any more
mice coming in? My house is an old cottage next to fields, and there are
literally dozens of gaps and holes in my house.
Thanks again sir,
Barry Slaven.

Rodent control always starts from the outside, closing up gaps and holes
where the mice are gaining access. After that is completed you can easily
catch mice using simple snap traps. For closing holes the best product is
Xcluder and the M-7 mouse traps are the best snap trap. Both are available
on this website. Click on "Pest Control Products" at the top of this page.

I am using one of those rotating traps baited with peanut butter at the
suggestion on the box. No luck. I know where he is but no bites. Is it time
to step up to a better trap and if so, what do I use as bait?
Ask the Exterminator
21 Jun 2011, 09:34
It's not the trap. It's the way you place the trap. Pre-baiting is also
required so that the mice adjust to having the object in their environment.
Click on "Mice" in the category list on the left side of this page and read
some of the articles on trapping and baiting.

So a wild or pet mice could live on and thrive on eating a diet of only dry
dog kibble?
Ask the Exterminator

Mice can usually get enough moisture out of the food they eat to satisfy
their need for water for a long time.

I woke up this morning to find that our bowl full of apples and bananas had
been disturbed. The bananas appeared to be untouched but about 6 apples
had been nibbled on, a few of them quite extensively. We've had mice
before but I've never seen them eat fruit. Could this be a rat instead?
Also, does the fact that several of them were bitten suggest a pack of
rodents? Quite concerned and disgusted. Any guidance would be greatly
appreciated.
Ask the Exterminator
24 Oct 2011, 11:02
Mice are nibblers. They will eat a wide variety of foods, including fruit,
if available. My suggestion is to put out a dozen snap traps. Pre-bait the
traps with tiny pieces of apple. Read about how to do this at this link:

About the glue trap- I'm an Apartment Manager & called an animal trapper
here to get rid of a gopher. He said the Regular Mouse traps are better or
even poison than the glue traps. When they get stuck in a glue trap they
will eat themselves to get free. You can safely trap a skunk or a possum
w/ a cage. The skunk may spray so you have to put a blanket over the cage
after it's caught. Then you can drop it off at the Madrona Marsh or call
someome to help you. But if you catch an animal you have to attend to it.
You can't let it sit in the cage in hot sun without food and water. I
would never use the glue traps. I had a bunny and a rat as a kid and they
do have feelings.

Micheal: Mice eat fresh, clean food. They will eat fresh insects, too. The
paper they chew on is for their nests.

We usually get mice this time of year and trap them with a glue trap.
Recently we found that looks like a small nut, never seen it before. Could
the mice be bringing them into the house? I can find out where hey are
getting in from out side, any tips?

For the person having a hard time traping the mice. You can set the wood
traps up against the wall. But somtime it doesn't work. You can by a
tapping cage w/food but even this is difficult- way more difficult for the
rate.
I've had success w/trap for skunks & possums, but not rats and mice.
The only way I got rid of the mice is/ with bait poison. I felt fad but
the trap failed & I couln't risk a tenant being injured. In Israel they
are studying rats. If a trapped rat is in an compartment- they will free
it 1st then eat a treat with them. I also noted my pet rat when I was 5
five mesmerized my house. Same with my bunny. He'd eat marigolds- but not
Oleaneder. The rodent family is intelligent as proved by Israel's lab.
