7 Effective Homemade Mouse Poisons Used To Kill Mice

Any home or business may experience a pair of mice taking up residence. Unfortunately, that pair of mice have the potential of turning into over one hundred mice in a year’s time. A female mouse is ready to breed in six weeks after birth. She can produce up to 10 liters per year, with up to 14 tiny mice in each liter.

It doesn’t take a math genius to figure out a home or business can quickly become infested with unwanted rodents. Every dwelling needs a plan for the best way to get rid of mice, so that as soon at one rat is spotted, action can be taken to prevent an infestation.

Look over these 7 effective homemade mouse poisons used to kill mice and print out the ones that you think will work best for your mice problem. The recipes and how to use them are also included. As a bonus, not all of these ‘poisons’ are true poisons and are safe for use around household pets. Other recipes are for homemade rat poisons concocted to kill mice and will be toxic to pets. Read and follow directions carefully so only the unwanted rodents will be harmed, not pets or children.

** Mice are almost blind and travel close to walls, feeling their way with whiskers. Place whatever type of mouse poison you make close to a wall, baseboard or cabinet wall for best results.

Homemade Mouse Poisons To Deal With Mouse Problem

1- Instant Mashed Potatoes

This is a pet-friendly and kid safe DIY recipe that will effectively and efficiently get rid of a mouse.

If your see a mouse or evidence a mouse has been in an area (droppings or chewed items), place two tablespoons of instant mashed potatoes flakes in a shallow lid and place in the location. The mice will eat the potatoes flakes and become very thirsty. They will seek out water and drinking the water will cause the instant mashed potato flakes to swell up in their stomachs and kill them.

Pets and kids probably won’t disturb the potato flakes, but if they do consume the small amount of instant mashed potatoes it won’t harm them.

You can entice the mouse even more by sprinkling a little artificial sweetener over the instant potato flakes. The sweet aroma and taste is irresistible to mice, and artificial sweeteners, like Equal and Nutrisweet, are deadly to mice.

2- Peanut Butter And Artificial Sweetener

Cheap, easy and effective way to get rid of mice. As long as there is no one in the household with a peanut allergy, this is one of the best mouse poisons.

Mice love peanut butter and the aroma is intoxicating to them, drawing them to scent from great distances. Purchase the cheapest peanut butter available and mix in an inexpensive brand of artificial sweetener to create poison that is deadly to mice, yet safe for humans and pets.

Mix in two packets of artificial sweetener (any brand, as long as it contains Aspartame) into two teaspoons of creamy peanut butter. Roll into balls that are slightly larger than a pea. Place this peanut butter balls in areas where mice or evidence of mice have been spotted. If there are any mice anywhere in the building they will soon come after this irresistible and deadly treat.

Peanut butter and instant mashed potato flakes can be used to create rat poison balls too. Add a little artificial sweetener to that mixture also.

3- Cement Mix

A little bit of cement mix will go a long way when used to kill rats. This homemade mouse poison can only be used where there are no pets as this will bring about sure death for pets too. Keep this mixture away from areas where children may be too.

Dry cement mix will harden in the digestive system of mice and kill them very quickly. But you have to get the mice to eat the mix, so a tasty filler ingredient is needed.

Peanut butter is a good filler ingredient to mix with dry cement mix. The peanut butter does not contain enough moisture to cause the cement mix to harden. Create this mouse poison by mixing equal parts of cement mix and peanut butter. Sprinkle a little artificial sweetener into the mix if you want to make it even more tasty to mice.

Roll into small balls, about the size of peas, and place along walls where mice have been spotted.

Keep a close check on these cement balls and change them every two days if left untouched by the mice. The cement tends to harden after a couple days of exposure to the elements and rats won’t touch it unless it’s soft.

4- Baking Soda

Safe for kids and pets, deadly for rats. Baking soda can be found in most kitchens and is a needed ingredient in baked goods. It’s also a natural product that is used to treat indigestion and several other health and household issues. It is also one of the best mice poisons.

Humans often mix a teaspoon of baking soda in a glass of water and drink to settle an upset stomach. The baking soda reduces stomach acid and creates carbon dioxide in the digestive system that is naturally eliminated. Mice are incapable of expelling carbon dioxide like humans can. After a mouse ingests baking soda, the gas builds up inside the stomach or intestines until the mouse explodes.

Baking soda will have to be mixed with a filler food to entice a rat to eat it. Peanut butter is a good choice. Mix equal parts of peanut butter and baking soda together, form pea sized balls and place where mice have been seen. *Avoid this homemade mouse poison if anyone in the building has a peanut allergy.*

Mix equal amounts of flour, sugar and baking soda, then place the powder mixture in a shallow lid and place near a wall where mice have been spotted. This mixture is safe for children and pets.

Cocoa powder has an enticing chocolate scent that will attract mice. Mix equal part of cocoa and baking soda, then place in a shallow lid near a wall.

5- Plaster of Paris

This is a common product used to create molds and casts. It can also be used as a homemade mouse killer.

Plaster of Paris is a dry product and must be mixed with liquid to be used for its intended purpose. As an alternative rodent poison, the product will need to be mixed with another dry food ingredient to entice mice to eat it.

Mix dry Plaster of Paris with sugar or corn meal to create a tasty rodent meal. Place the dry ingredients in a shallow jar lid in the area where mice have been seen. Once eaten, the Plaster of Paris will mix with the moisture inside the rat’s stomach and harden, bringing about a quick death.

This is not safe to use around pets or children. Check jar lids every other day and replace product for best results.

6- Vitamin D

Crushed vitamin D tablets are effective at killing mice. Consuming vitamin D causes the calcium level in a mouse to rise up to level that will cause calcification of the heart. This calcification will kill the mouse, but it will be a slow process. The mouse will have to consume the vitamin D over a two-three day period before death occurs.

Crush three vitamin D tablets and mix into a tablespoon of peanut butter. Roll into pea size balls and place where rodents have been seen, but away from children and pets.

7- Chicken Broth and Boric Acid

The aroma of chicken broth will lure mice in and entice them to eat. The boric acid concealed under the chicken aroma will kill the rat soon after it has been consumed.

Place two tablespoons of dry boric acid (found near the laundry products at the supermarket) in a small bowl. Slowly pour chicken broth into the boric acid, adding just enough to make a paste. Roll into pea sized balls and place in a location where mice have been seen, but away from children and pets. These balls will dry out quickly and rats will not eat them after they dry out, so replace daily for best results.

Where Do Mice Come From?

Mice can enter a structure through a variety of ways, and they are looking for a food source and shelter. Since the breeding and birthing process happens every 21 days, the ideal location will have a dark, shelter area to have babies with food and water nearby.

A mouse can climb very well and will enter a building through an open window, even on a second or third floor level. Cracks or cervices in the foundation is an open invitation for a rat to come in. All it needs is a 1/4 inch space and it’s in. Mice will easily chew through caulking or insulation to gain entry.

Mice are very attracted to spilled food and beverages, clutter and trash. The cleaner the environment, the less likely it is to have a rodent infestation. Keep outside free of debris and minimize the amount of clutter and stored items indoors to reduce the likelihood of rodents taken up residence in your home or office building.

Store all boxed food items, especially cereal grains, in glass jars. Mice can smell food through cardboard boxes and will easily chew through them to the food stored inside the box. Don’t leave pet food bowl out at night either, dry dog or cat food are favorite food sources for mice.
