Are unwelcome cockroaches making themselves at home in your space? Before you reach for harsh chemicals, consider a widely known and simple DIY solution using common kitchen ingredients you likely already have on hand.
This method combines baking soda and powdered sugar to create a bait that can help manage cockroach populations. It’s an accessible option for those looking for a practical, low-cost approach to pest control.

What You’ll Need
- 1/2 cup Baking Soda
- 1/2 cup Powdered Sugar
- Small mixing bowl
- Spoon
Why This DIY Can Be Useful
The effectiveness of this DIY solution lies in the distinct roles of its two main ingredients. Powdered sugar acts as an attractant, luring cockroaches to the mixture with its sweetness. Once ingested, the baking soda interferes with their digestive systems. Cockroaches cannot properly process baking soda, which can disrupt their internal balance.
How to Make It
- In your small mixing bowl, combine the 1/2 cup of baking soda and 1/2 cup of powdered sugar.
- Stir well with the spoon until both ingredients are thoroughly mixed together, creating a uniform powder.
How to Use It
- Sprinkle a thin, even layer of the mixture in areas where you’ve noticed cockroach activity. Common spots include under sinks, behind appliances like refrigerators or stoves, and along baseboards where cockroaches tend to travel.
- Ensure the application areas are dry before sprinkling the mixture. Moisture can reduce its effectiveness.
- Reapply as needed, especially after cleaning the area or if the mixture becomes damp or gets scattered.
What to Expect
This mixture is designed to help control cockroach populations by attracting them and then affecting their digestive systems. While it may not eliminate an entire infestation instantly, consistent application can contribute to a noticeable reduction in cockroach activity over time. Results may vary depending on the severity of your pest problem and the consistency of application.
Helpful Tips
- Strategic Placement: Place small amounts in out-of-the-way areas where cockroaches are likely to forage, but less likely to be disturbed by everyday activities.
- Consistency is Key: For best results, reapply the mixture regularly, especially if you notice new signs of activity.
- Cleanliness: Maintain a clean environment. Removing other food sources can make the sugar-baking soda mixture even more appealing to hungry cockroaches.
Important Notes / Safety
- Keep Away from Children and Pets: Always place this mixture in spots inaccessible to children and pets. While generally considered non-toxic in small amounts, it’s best to avoid accidental ingestion.
- Monitor and Adjust: Observe the areas where you’ve placed the mixture. If you’re not seeing the desired results, you might need to adjust placement or consider other pest control methods.
- Ventilation: When applying, ensure good ventilation in enclosed spaces, especially if sprinkling a larger quantity.
