How To Make Borax Balls for Roaches

Roaches 1

Dealing with a roach infestation can be distressing and challenging. But don’t worry, we have a DIY solution that can help you tackle this problem effectively: Borax balls. This comprehensive guide will teach you how to make borax balls for roaches, explain their effectiveness, and provide essential safety guidelines to follow.


To make borax balls for roaches, mix equal parts of white flour and borax in a bowl, add a quarter amount of confectioners or brown sugar, then gradually add water to form a dough-like consistency. Roll this dough into small, marble-sized balls. Place these balls in areas where roaches are commonly found, ensuring they are out of reach of pets and children. Borax works by poisoning and dehydrating the roaches when they ingest it. Always remember to handle and use borax balls with caution due to their toxicity.

What are Borax Balls?

Borax balls are a homemade pest control solution made from borax, a naturally occurring mineral, and other household ingredients. The borax acts as a poison for roaches, while the other ingredients serve as bait.

Ingredients and Materials

To make borax balls, you will need:

  • Borax or boric acid
  • White flour
  • Confectioners or brown sugar
  • Water
  • Mixing bowl
  • Spoon
  • Gloves (optional)

Step-by-Step Guide to Making Borax Balls

  1. Mix equal parts (50/50) of white flour and borax or boric acid in a mixing bowl.
  2. Add about 1/4 of the amount of flour used in confectioners or brown sugar to the mixture.
  3. Gradually add water to the mixture to create a dough-like consistency. Make sure it’s not too runny.
  4. Roll the dough into small, marble-sized balls.

How to Use Borax Balls for Maximum Effectiveness?

Place the balls strategically in hidden areas where roaches are commonly found, ensuring they are out of reach of pets and children. Some suggested locations include:

  • Behind fridges
  • Behind dishwashers
  • In corners of cupboards, cabinets, and drawers
  • Under furniture
  • Under stoves (be careful that the area doesn’t get too hot)
  • Along floorboards
  • Around the garbage
  • Behind flower pots

Remember to monitor the effectiveness of the baits and replace them as necessary.

How Does Borax Work on Roaches?

Borax works by sticking to the roaches’ legs and body due to static electricity. When the roach cleans itself, it ingests the borax, which then acts as a poison, damaging its digestive system and exoskeleton. The sodium in borax also dehydrates the roaches, leading to their demise.

Safety Precautions

When handling and using borax balls, remember to follow these safety precautions:

  1. Keep borax balls out of reach of children and pets.
  2. Wear gloves when preparing borax balls.
  3. Ventilate the area when using borax.
  4. Monitor the effectiveness of the baits and replace them as necessary.
  5. Clean up after using borax balls.

Potential Drawbacks

Despite their effectiveness, borax balls have some downsides:

  1. Toxicity: Borax is toxic to humans and pets when ingested in large quantities.
  2. Time-consuming: Borax doesn’t kill roaches instantly. It takes about 72 hours to kill a roach after ingestion.
  3. Ineffectiveness without bait: Borax itself doesn’t attract roaches, so it needs to be mixed with an attractive bait.


Borax balls can be an effective method for killing roaches, but they should be used with caution. Always remember to keep them away from children and pets, use attractive bait, and maintain cleanliness in your home to prevent further infestations. If the infestation becomes too severe, consider contacting a professional pest control service for assistance.

With proper use and precautions, borax balls can help you reclaim your home from roaches, providing a safer and more comfortable living environment.

Frequently Asked Questions

Can I substitute borax with something else if I don’t have it at home?

Yes, you can substitute borax with boric acid in this recipe. Both borax and boric acid have similar properties that are toxic to roaches.

How long do I need to leave the borax balls before replacing them?

It’s best to check the borax balls every few days. If they appear to be worn out or have been eaten, it’s time to replace them.

Can I use borax balls to get rid of other pests?

Yes, borax balls can also be effective against ants and some other types of pests. However, the effectiveness may vary depending on the specific type of pest.

How many borax balls do I need to prepare for a small infestation?

The number of borax balls needed can vary depending on the extent of the infestation. For a small infestation, around 10-15 balls should be sufficient. However, you may need to prepare more if the infestation is larger.

Is borax safe to use around plants?

Borax can be harmful to plants if used in large quantities. However, in small amounts like in borax balls, it should not have a significant impact on plants. Always remember to place borax balls out of reach of pets and children.
