The Weird DIY Mouse Repellent That Actually Worked (And It’s Safe Around Kids!)

I was fed up.

For weeks, Iโ€™d been hearing scratching noises behind the walls and in the kitchen corners at night. I tried everythingโ€”snap traps, glue traps, and even poison baits. But nothing seemed to work long-term.

Worse? I have young kids at home. Leaving out toxic traps or chemicals just didnโ€™t sit right with me. I was constantly worried that a tiny hand or curious pet would find something dangerous before the mice did.

Then, during a backyard chat, my neighbor leaned in and said:

โ€œTry Colgate and tomato paste.โ€

I blinked.
โ€œLikeโ€ฆ toothpaste? With tomatoes?โ€
She nodded.
โ€œItโ€™s weird, but trust me.โ€

I laughed at first. It sounded like some off-the-wall internet myth. But by then, I was desperate enough to try anything.


The DIY Mix That Changed Everything

That night, I followed her simple instructions:

๐Ÿงด The Recipe:

  • 1 tablespoon of Colgate (white toothpaste)
  • 1 tablespoon of tomato paste
  • Optional: a sprinkle of baking soda (for extra smell control)

I stirred the mixture until smooth and placed a small spoonful on a piece of cardboard. I set two of these in kitchen corners, behind the stove, and near the pantry.


What Happened Next Surprised Me

I went to bed thinking, Well, at least the kitchen smells minty nowโ€ฆ

But the next morning?
Total silence.

โœ”๏ธ No scratching behind the fridge.
โœ”๏ธ No new droppings.
โœ”๏ธ No chewed-through snack bags.

I checked the usual hiding spots โ€” under the sink, behind appliances, in dark corners โ€” and saw nothing. No movement. No mess. No mice.

And it stayed that way.


Why Does Colgate & Tomato Paste Work?

It sounds like an odd combo, but hereโ€™s the logic:

โœ… Toothpaste (Colgate)

  • The strong menthol and fluoride smell overwhelms the rodentโ€™s sensitive nose.
  • It acts as a natural repellent, making the area uncomfortable for them.
  • Some say ingesting even a small amount is enough to drive them away for good.

๐Ÿ… Tomato Paste

  • Acts as a bait to attract them.
  • Mice are drawn to the smell of food, and tomato paste masks the scent of the menthol just enough to entice them.
  • Once they nibble, theyโ€™re repelled by the overwhelming mint and bitter taste.

Together, the mix confuses and drives away mice, without harming them โ€” or your family.


Safe, Cheap, and Shockingly Effective

This isnโ€™t just effective โ€” itโ€™s also:

  • โœ… Non-toxic (no worries about kids or pets getting hurt)
  • โœ… Easy to make (two pantry items!)
  • โœ… Budget-friendly (no expensive traps or exterminators)

And best of all, youโ€™ll know itโ€™s working fast. Most people see results in a single night.


Where to Place It

  • Behind the stove
  • Under the sink
  • Pantry corners
  • Inside cabinets
  • Anywhere youโ€™ve seen droppings or scratching

Refresh the mix every 2โ€“3 days if needed.


Final Thoughts

I never thought Iโ€™d be praising a mix of Colgate and tomato paste, but here we are.

If youโ€™re tired of:

  • Poison traps
  • Snap traps
  • Glue boards
  • Cleaning up mouse droppings every morningโ€ฆ

โ€ฆand youโ€™re looking for something safe, smart, and weirdly effective โ€” give this mix a try. It worked for me, and Iโ€™ll never go back to toxic methods again.

Sometimes, the simplest solution is sitting right in your bathroom drawer and fridge door.
