What Do Wild Mice Eat
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'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.

I just started defrosting some gumbo I had in my freezer and noticed that the bag was leaking pretty badly (we store our frozen food in ziploc bags when possible for easy stacking) and threw the bag out. Grabbed another bag of gumbo and saw what appear to be bite marks on that bag too. This seems like an outlandish question to me, but is it possible for mice to get in the freezer? Thanks!

I have mice in my basement. I have never seen them, but I can smell their droppings, and see other evidence like shredded paper, etc.
There's no food down there, but until recently the basement was full of spiders and other creepy-crawlies. About a week ago, I decided to fumigate with "Raid Fumigator," which contains permethrin as the active ingredient.
Now all the bugs are gone, but I'm wondering two things. First, would the permethrin have likely either killed or driven out the mice? And second, with no more bugs down there (hence nothing to eat) will they likely abandon the basement on their own?
Thanks,

P.S. It's hysterical all the commenters who want your help raising mice. LOL...as you noted above, it's your job to kill them.

You need to put out two dozen mouse traps and you need to read my article on how to properly set mouse traps. The articles are listed under "Mice" in the category list on the left side of any page.
