Most people think leftover rice is just kitchen waste, but many home cleaning enthusiasts say it can actually become a surprisingly useful household trick.

Recently, a simple method using:

leftover rice mixed with detergent

has gone viral online because it may help:

• clean greasy surfaces,
• remove stubborn dirt,
• and even attract and eliminate cockroaches.

Why Does This Trick Work?

The sticky texture of rice helps absorb oil and grime, while detergent contains chemicals that break down grease and may affect insects.

According to many home users, when cockroaches eat leftover rice mixed with detergent residue, the detergent may disrupt their digestive system and eventually kill them.

That’s why some people place small portions of the mixture in:

• kitchen corners,
• near drains,
• behind refrigerators,
• or dark humid areas where cockroaches often appear.

How People Usually Make It

The method is simple:

• Mix leftover rice with a small amount of detergent.
• Add a little water to create a sticky mixture.
• Place small amounts onto paper or shallow lids.
• Leave them near cockroach hiding spots overnight.

Many people online claim they notice fewer cockroaches after several days.

Why The Trick Became Popular

Besides being cheap and easy, the method also helps:

• reduce food waste,
• reuse leftover rice,
• and avoid stronger chemical sprays.

However, experts still warn that detergent should always be kept:

• away from children,
• pets,
• and food preparation areas.

For severe infestations, professional pest control may still be necessary.

Still, many people were surprised to discover that something as ordinary as:

leftover rice and detergent

could turn into an unexpected household hack.
