15 Homemade Mouse Poison & Traps To Get Rid Of Pests

By: Ashley Ziegler |

There is nothing good about finding evidence of mice in your home. They are unpleasant and unwelcome guests that can be really difficult to get rid of. 

If the idea of setting and cleaning up a traditional mousetrap doesn’t appeal to you, consider homemade mouse poison. Many of them don’t take effect until later (so less clean up for you) but will definitely do what it takes to rid your house of the pests.

This is one of the best and most effective poison recipes out there, and it doesn’t take much to make. 

Chances are good you don’t have boric acid powder sitting around the house, so you’ll want to grab that at the store, mix it with some chicken broth, and wait for the mice to appear.

Sugar Formula

This homemade mouse killer calls for baking soda, flour, sugar, and water – which you probably have on hand (for baking cookies, of course). 

The baking soda is what is poisonous to the mice and the sugar is the bait. Just place it in areas mice will get to and they’ll be gone in no time.

At first, dried mashed potato flakes won’t do much to the mice except fill them up. 

Later, when they drink some water, the flakes will expand and eventually kill the little critters. But, if there’s any way to go, it’s with a belly full of mashed potatoes, right?

Peppermint has an effect on two pests, mice and rats. 

For mice, it will serve as a repellant, so put it around places they tend to get in. For rats, it works as a poison and will shrink up their lungs.

This homemade mouse bait and poison is both simple and effective in getting mice out of your home – for good. 

You’ll mix some cornmeal and milk with the Plaster of Paris and roll it up into a ball. Before long, you’ll notice less and less little mice bites in those balls, so you’ll know it did its job.

It’s no shock that cement is a mouse killer – it’s probably not something anyone should ingest. 

To make this poison, use a similar process as the Plaster of Paris, roll it up into a little ball with a good mouse bait, and wait for them to devour it.

While vitamin D is wonderful for humans, it’s fatal for mice because it calcifies their little hearts. 

You’ll want to crush up the vitamin D and roll up into a ball with peanut butter. This process isn’t quick, so you’ll need to wait a couple of days to notice a difference in the number of little visitors.

If you opt for this poison recipe, make sure you keep it away from kids and pets, as it can be harmful to them as well. 

For mice, crush up the zinc and mix it up with bait. After ingesting the zinc, it will create a toxic gas in their digestive system that will result in death.

One of the biggest things to focus on with any poison recipe is the bait you use. 

Cocoa Powder is an effective bait because it smells delicious, can be easily mixed with other powders or liquids, and covers of the smell of any poisons you pick (like Plaster of Paris).

The mice don’t have to actually ingest the black pepper in order for it to be effective, just the smell alone will do it. 

Put some of the pepper in a place where the mice congregate or right at their point of entry. The fumes will kill them off, according to Lake Norman Pest.

Conclusion

Homemade mouse poison can be just as effective, but way less costly, as store-bought. Cleaning up the mess of a traditional mouse trap is unpleasant for most people, so getting rid of the problem without having to actually see the end result is preferable. 

No matter what bait, formula, or method you choose, a homemade mouse killer is a sure way to get them out of your house – for good.
