Yes, a mixture of baking soda and sugar can kill roaches, but it’s most effective for small infestations and requires proper placement & patience.

How It Works

The concept is simple…

• Sugar attracts the cockroaches.

• Baking soda reacts with the acid in their digestive system.

• This reaction produces gas that roaches can’t release, eventually killing them from internal pressure.

How to Use It Effectively

To make your own bait…

• Mix equal parts baking soda and sugar.

• Place small amounts in shallow dishes or jar lids.

• Set the baits in high-traffic roach areas: under sinks, behind appliances, and near baseboards.

• Refresh every few days and maintain a clean environment.

Does It Work for All Roaches?

It can kill individual roaches, but it won’t wipe out large infestations or reach hidden nests. For serious problems, use it as a supplement to professional pest control.

The baking soda & sugar method is a safe, low-cost DIY solution for dealing with occasional roaches. While it’s not a complete fix, it’s a helpful step toward reducing their presence when combined with good sanitation and exclusion methods.
