Why You Need To Get Rid of Mice

The centers for control and disease prevention have listed dangerous diseases that rodents can spread. This list contains diseases like Lassa fever, Monkeypox, and salmonellosis. To protect your health and your household from this safety risk, you must immediately get rid of these mice.

Does Bleach Repel Mice?

Mice have a keen sense of smell that helps them detect their food, and bleach is known for its strong chlorine-like smell.

The smell of bleach affects the sense of smell of mice, making them repulsed by it. However, you will need a high concentration of this substance to keep them away.

Mice can also die from ingesting bleach as it contains several toxic chemicals like Calcium hypochlorite, sodium hypochlorite, and sodium hydroxide.

These chemicals in the guts of mice will cause hyperchloremia, a condition that occurs when there’s too much chlorine in the blood.

However, if you aim to kill mice using bleach, it may be harder than you think, as their sense of smell helps them flee from food items that contain bleach. This is why bleach is mostly effective for keeping them out and not killing them.

While it is important to use a high concentration of bleach to get mice to leave, you should be careful not to let the smell affect you and other people in your home. You can dilute the bleach with some water if it’s too concentrated.

Spray other suspected areas in your home and yard with chlorine; when these mice come with this chemical, they will take off immediately.

You can soak a cotton ball with bleach and place them in these areas as an alternative to spraying; this alternative is a good way to preserve this harsh smell for a longer time.

2. Mixing Food Items With Bleach To Get Rid of Mice

If you get frequent invasions by mice and other rodents, eliminating them for good sounds like a preferable option to chasing them away as they may return.

Since mice can detect bleach and run away from it, you need the perfect food item to lure them and conceal the smell of bleach simultaneously.

Keeping your living environment clean is one major way to reduce the population of mice in your environment, and here are some steps to help you have a more secure cleaning routine using bleach.

Before starting, put on a nose mask and protective gloves. This is because the smell of concentrated bleach is too strong and can make you feel uncomfortable on continuous exposure, bleach can also irritate when it gets on your skin, so you need protective gloves.

Step two

Step five

After letting the droppings, nesting materials, and other mess soak in bleach for some minutes, clean them up using paper towels and discard these papers in your outdoor garbage bin.

Step six

you will need to thoroughly clean up these areas previously infested with rats to ensure that no harmful disease is spread. Disinfection can be done with the bleach solution alone or with the help of other disinfectants.

Step seven

After cleaning and disinfection, you must wash your hands to kill any germs from this task. It is best to wash your hands with soap rather than with water alone.

Other Smells That Repel Mice

Bleach is not the only substance with a strong smell that mice find obnoxious. These smells are usually generated from herbs; you can use these plants’ extracts as essential oils while warding off mice.
