Killing mice with toothpaste; Does toothpaste kill mice if they eat it?

Killing Mice With Toothpaste
Toothpaste Can Kill Mice

Mice can be killed by toothpaste, but only if they consume a large enough quantity. In moderation, mice can survive; but, the excess might be harmful. In the case of toothpaste, a fatal dose is likely around the size of a pea.

A pea-sized amount of toothpaste is around 0.4 grams, and this amount contains 0.972 mg of sodium fluoride (NaF) (NaF). Toothpaste contains the chemical NaF, which is lethal to mice if swallowed.

A rat can be killed with 52 mg NaF therefore we may use that as a reference for mice if we take their smaller weight into account. Mice range in weight from 17 to 25 grams (0.017 to 0.025 kg). So, 52 x 0.017 = 0.884 mg NaF.

A 0.017-kilogram mouse would likely die from this dose. And, 52 x 0.025 = 1.3 mg NaF. This would be enough to kill a 0.025-kilogram mouse.

While toothpaste can kill mice if they eat a pea-sized amount, will they actually eat this amount? It depends. However, it’s really unlikely.

In the average home coping with the usual mouse infestation, there will be many more enticing food sources to mice than toothpaste.

Foods like peanut butter, candy, and other sweets are prized by mice but not toothpaste (peanut butter is THE biggest delicacy).

To make the toothpaste more enticing to mice, you should mix it with other substances in foods if you intend to use it as a mouse repellent.

Is Toothpaste Poisonous to Mice?

It is true that mice are poisoned by toothpaste, and that mice are killed by toothpaste in high numbers.

Killing mice with toothpaste, make little balls (about the size of a pea) and scatter them about areas where mice have been observed to congregate.

If your home does not have many other sources of food readily available for mice, they can head right for the toothpaste and eat themselves to death.

The best toothpaste approach, however, is a more complicated mixture of toothpaste poison balls. The following items are required for the execution of this procedure:

  • 4 tablespoons of salted peanuts
  • 1 tablespoon of baking powder
  • 2 tablespoons of flour
  • Toothpaste, two tablespoons
  • 1 tbsp. of sugar

This is the most effective strategy for killing mice with toothpaste, as the variety of ingredients in the poison balls makes them more tempting to mice.


What other household items get rid of mice?

  • Baking soda: Mice will rush to the bowl and their stomachs will virtually explode when they ingest the concoction, causing close to immediate death.
    Baking soda is a common household item and one of the most efficient home treatments to kill mice and rats. Add some baking soda powder and a sweetener like chocolate or sugar to a bowl.
  • Peppermint Oil: Peppermint oil is another household item and one of the greatest ways to get rid of and repel mice. Peppermint oil is an enjoyable scent to most humans, but the fresh, overpowering aroma may be rather annoying to a mouse’s responsive nose.Try pouring a few drops of peppermint oil on cotton balls and placing them throughout your house. Put the cotton balls in spots where mice are getting entry into your home and in your kitchen cabinets to keep them away.Planting raw mint plants or dabs of oil around the outside of your house can help deter them. Peppermint oil has the added benefit of killing nasties like spiders and mites.

Mice and rats are attracted to the lovely aroma of a bay leaf.However, the leaves produce secondary compounds that are toxic to mice when swallowed. If you want to get rid of mice, try putting bay leaves around your house.

Traditional pest control methods are some of the most effective at-home cures. Steel wool does wonderfully at keeping mice out of small locations.

If you detect any little gaps or holes around your house, fill them with steel wool to keep out rodents.

Furthermore, while not quite exactly a home cure or common household item, snap traps with peanut butter perform a fantastic job at trapping and killing rats and mice.

You can acquire snap traps at most local hardware stores and peanut butter is one of the most enticing feeds for mice.

There are several other ways to get rid of mice, but it’s easy to become lost in the maze of options when doing research. It’s best to stick to a few tried-and-true strategies until you see results.]

However, if you have a significant infestation, it may take weeks before you start seeing results from your trapping tactics, which is why many people feel disheartened when they don’t see any.


Does Toothpaste Kill Rats?

Rats can be killed by toothpaste, but the active chemicals in the paste must be present for this to happen. If the toothpaste comprises ethylene glycol and fluorine as active components, the rat will be in difficulty.

A blockage will occur if the rat eats the paste (which contains the components) before it reaches its muzzle.

It will be difficult for the rat’s food to pass out of its system because it can’t vomit the paste. If the rat eats enough of the paste, it could lead to mortality.

If you intended to use the paste to kill a rat, you need to hope that the critter ingests it. So long as people don’t eat toothpaste, they won’t be consuming any sodium fluoride. This suggests that the rat will keep sliding over your ceilings and slithering behind your walls.
