Can You Use Boric Acid To Kill Roaches?
Yes, you absolutely can use boric acid to kill cockroaches! It has been used for many years and is even used by professionals.
Boric acid is an awesome roach killer for 3 reasons:
- It breaks down the tough roach body.

- If a roach eats another roach killed with boric acid, the cycle begins again!
These are the reasons why boric acid is one of the best natural roach killers you can buy!
5 Ways Of Using Boric Acid To Kill Cockroaches
1. Make Boric Balls
One tip is to make balls of tasty food for the roaches. There is one hidden ingredient they won’t enjoy… not in the long to medium term anyhow. That is boric acid!
The good news for you is that cockroaches literally eat anything! They have a preference for sweet tuff (don’t we all?), so use that to your advantage.
Make tiny boric balls with the following ingredients:
- 1/2 cup of flour (any flour)
- 1/2 cup boric acid
- 1/4 cup sugar
- 1/4 cup milk
Mix the ingredients until you get a pie-like consistency. Break out tiny chunks of the mixture and roll them into balls. Place them around your home where you have noticed roach activity.
2. Make Boric Spray
Another option is to add the boric acid to a water spray bottle to use as and when you need to.
- 1/2 cup boric acid
- 1 pint of water
Make sure it is mixed thoroughly. Spray this mixture in all areas where you have seen roach activity. Also, if you are a good shot, you should be targeting direct hits on a roach! It is a skill that required quick reflexes, a sharp eye, and tremendous athletic ability!
3. Scatter Powder
This is probably the easiest method of using boric acid to kill cockroaches!
Scatter the boric acid in areas where you have seen roaches or in areas where there is a supply of food or water. Many things attract roaches to your home, so use that knowledge to understand where you need to put the boric acid.
The roaches will scurry through the powder, which sticks to their feet. Roaches groom themselves regularly to remove debris from their feet. They do this by running feet through their mouth. Bingo… the roach consumes the boric acid!
4. Add To Traps
If you have roach traps set up around your home, you should scatter boric acid around the trap entrance and inside the trap (if you can).
Some traps have roach bait inside, so roaches are already drawn by the scent. As they approach the bait station, they will get boric acid on their feet which is consumed as part of the grooming process (see above).
If the roach enters the trap, the boric acid is just another thing that will kill them!
5. Mix Into Water
Roaches need water. In fact, it is one of the things that roaches look for while they scurry around your home.
You could leave trays of ‘boric acid’ water in areas where you have noticed roach activity, as they will be drawn to these.
The water should contain boric acid. When the roach drinks the water, the boric acid is consumed.
Use the same mix as above:
- 1/2 cup of boric acid
- 1 pint of water
Mix thoroughly and separate into a few trays. Scatter these trays around your home.

Once you have made the boric balls or made up the spray, you need to know where to use it. Here is a quick bullet point guide. Use boric in the following places to kill roaches:
- Near a water supply – Any leaking pipes or small accumulations of water.
