Grapes/raisins, chocolate, avocado, garlic, onion, rhubarb, coffee, tea, alcohol, and walnuts must not be fed as they are toxic to mice. Lettuce should be avoided as it can cause diarrhoea in mice [4].
One way to do this is to mix some cocoa powder and flour with baking soda or boric acid. Baking soda or boric acid creates a lot of gas inside the rodent's digestive system. The mouse does not have the ability to expel this much amount of gas, so it eventually kills them.
A rat's stomach forms a cyanide reaction from raw sweet potatoes; therefore, mixing it with any food will repel rats naturally. While it's not enough to kill an adult rat, it can kill a mouse.
Vegetables: There are also many fresh vegetable options that can be fed to mice. Broccoli, cabbage, Brussels sprouts, endive, carrots, bok choy/other Asian greens, celery, parsley, corn, beans, peas, and tomatoes can all be used.
A balanced diet for mice
Mice are opportunistic omnivores and will eat both plant and animal-based food. Wild mice eat a wide variety of seeds, grains and other plant material, as well as invertebrates, small vertebrates and carrion.
They also like to finish their breakfast with a small corner of toast and vegemite. Water should be freely available, sipper bottles are best.
Fruit By the (Mouse) Foot
Most households have some sort of fruit—bananas, apples, oranges—kept openly on counters or even on top of microwaves. Mice will avoid these during the day but get bolder during the late night.
However, you might be surprised to learn that this isn't quite the case. Do mice eat cheese? The answer to that question is: yes. Mice will in fact eat cheese if it is available, but their supposed love for this food is a bit overexaggerated.
Vinegar. The pungent smell of vinegar is also a natural way to repel mice and rats. These pests cannot stand the sharp scent of vinegar, which means it can be used as an effective rodent repellent.
Pet mice's diets should also be complemented with vegetables and dried fruits. Most importantly, mice do not eat chocolate, garlic and onion. These foods should therefore be avoided.
Don't feed your mice citrus fruits like oranges, lemons or grapefruit.
Although they're technically omnivores, mice prefer a diet of grains, seeds, and fruits, essentially, anything high in carbohydrates. However, they aren't picky eaters and can live on a minimum of an ounce of food & water a day.
Sweet potato extract alleviates high-fat-diet-induced obesity in C57BL/6J mice, but not by inhibiting pancreatic lipases.
Zinc phosphide is an acute toxicant that causes the death of a house mouse within several hours after a lethal dose is ingested. It appears to be the fastest way of getting rid of mice by reducing their population.
Flour and sugar – mix equal parts of sugar, flour, and baking soda. Leave in a shallow dish. Cocoa powder – chocolate is difficult for anyone to resist, including mice. Combine equal amounts of cocoa powder and baking soda, and then add a little sugar to sweeten the deal.
All you need to do is mix 2 – 2 and a half cups of ammonia, 100 – 200 mL of water and a 2-3 spoonful of detergent in a bowl. Then, put it to places where rats are usually seen. The smell of ammonia is very pungent that it instantly kills rats.
Peppermint oil, cayenne pepper, pepper and cloves.
Mice are said to hate the smell of these. Lightly soak some cotton balls in oils from one or more of these foods and leave the cotton balls in places where you've had problems with mice.
While they cannot digest the substance after ingestion, their mouths become alkaline and burn their lips and tongues. Eventually, mice or rats die due to the baking soda's alkalinity overall. That is rather than its poisonous properties, similar to how mice or rats die from eating poison.
Repel rodents and insects
Rats, mice and other insect don't like the smell of peppermint, lemon, and cinnamon. Make tea with these rodent irritants and place the used teabags in places like the back of your pantry, under the kitchen sink or behind the refrigerator to repel these unwanted pests.
House mice are omnivorous but prefer to consume grains, fruits and seeds. Consequently, they may cause severe damage to crops and domestic gardens. Although it is commonly believed that mice are attracted to cheese, they tend to prefer foods that are higher in carbohydrates.
Mice are natural seed eaters, but inside homes they're very attracted to high-calorie sweets and fatty foods. Tiny bits of peanut butter or soft cheese have always worked well. Stick a pinch or two of marshmallows, gum drops or beef jerky to the trigger and the trap will spring when mice take a bite.
They are scared of bright lights and noises too. Mice have poor eyesight and thus rely on their sense of smell. They are repelled by the scent of cheese, for one.
Rodents like mice or rats will eat anything in sight and smell; loaf of bread with spread of peanut butter are definitely an excellent menu for these kind of pest.
Both rats and mice are good climbers and can climb vertical walls and "shimmy" up between walls and drain pipes. Rats are also excellent swimmers and have been known to enter premises through the water traps of the toilet bowl when infestations occur in the main sewerage system.
