Bleach as a rat poison

Does Bleach Keep Rats Away?

The answer is yes. As bleach is a strong chemical that works when it comes to households, we should know its effectiveness in keeping away rats and killing them.

If you want to have a homemade remedy for keeping rats away from your home, you can create a homemade recipe to repel rats with bleach.

Given that rats have lousy eyesight but a powerful sense of smell, they are easily attracted to sweet scents.

However, bleach doesn’t even emit a hint of a sweet aroma, but rats can still detect it. They have an extremely low tolerance for solid and irritating scents. Humans can tolerate the smell of bleach, while rats cannot. Hence, it affects their system in an instant.

Can Bleach Kill Rats?

We mentioned that rats could not tolerate bleach’s smell, so they keep away from those areas that smell like bleach. Bleach can deter rats.

However, keeping them away might not be a permanent solution because they may find their way to infest your place again.

Bleach can act as a rat repellent, but it can also be rat poison. Bleach as a repellent and as poison can be equally deadly to the rats.

Yes, killing rats with bleach can be effective. Despite its effectiveness as a poison to kill rats, it would not be easy for them to ingest the bleach as a poison since they have a low tolerance for its smell, as mentioned earlier.

The key to letting rats in your house ingest the bleach is to hide it from something that can lure them. 

How to Use Bleach to Get Rid of Rats?

It can be tricky to use bleach as your fighting agent for the rats, but we can utilize it if you note some of these simple ways to use bleach as either your repellent or poison.

Peanut Butter

The taste of peanut butter is sweet, and its butter scent is appealing for the rat’s nose at the same time. Using peanut butter as your cover to let mice ingest the bleach can be effective.

Mix bleach with one to two tablespoons of peanut butter with an equal ratio. Remember, it should not smell like bleach. It would help if you estimated the bleach you want to put, so there is a substantial amount that could kill rats after the ingestion, and the smell is like sweet peanut butter.

The buttery smell baits the rat and entices them into eating, then the ingested bleach mixture kills it. This is one of the ways to get rid of rats with bleach.


Dilute bleach in water and use a spray bottle for it to work as a disinfectant. Since bleach is used as a disinfectant, you can spray it onto the rat’s places to keep them away—spray their entrances and exits and the areas where they keep running around.

Cotton Balls

Maybe rats are moved only in one area, but soon enough, they’re going to infest your whole home. The goal is to get rid of them, and you can use cotton balls as a remedy.

It would be best if you place cotton balls in areas that you think rats go into and spray that cotton ball with bleach. You can also dip the cotton ball with bleach. Ensure that you use gloves when you do it, to avoid the bleach in contact with your skin.

Rats Coming Back

Will bleach kill rats?

If rats keep keep returning even when you have utilized the bleach in many ways, you can now use other home remedies. Place mousetraps to ensure they’re going to get caught.

Place them in places where rats don’t notice that it’s a foreign object. Use a bait for assurance, and make sure this bait can attract rats.
