Pro tip: For best results, refresh the mixture every two days. Also, consider adding some routine white vinegar cleaning and regular ventilation to discourage pests from returning.

Why This Works
Without getting too scientific, the onion’s strong aroma lures cockroaches, while the baking soda creates an environment they instinctively avoid.

Together, they offer a low-risk deterrent that’s both effective and gentle—no harmful chemicals involved, and safe for pets and kids.

Even better, using this method encourages a more eco-conscious approach to household maintenance. Fewer toxic sprays, fewer worries—more comfort at home.

Simple Habits That Keep Roaches at Bay
In addition to this DIY remedy, a few everyday practices can go a long way toward preventing infestations:

Seal food packages tightly.
Clean neglected spots, especially behind and under furniture.
Keep trash cans sealed.
Maintain drains with a mixture of baking soda and vinegar.
These small but consistent habits can make your home less inviting to pests and a lot more serene for you.

Because sometimes, the best solutions are also the simplest—and most natural. So why not let your kitchen help you create a cleaner, calmer living space?
