Lemon does not kill cockroaches, but it may help repel them.

Why Roaches Avoid Lemon

Cockroaches rely heavily on their sense of smell to find food and shelter. The strong citrus scent of lemon can overwhelm and repel them, making it a natural deterrent. While it won’t kill them, it may help keep them away from areas that are regularly cleaned with lemon-scented products.

How to Use Lemon as a Roach Repellent

To use lemon as a deterrent…

• Add lemon juice or lemon peels to your mop water

• Wipe down countertops, sinks, and baseboards with diluted lemon water

• Place fresh lemon peels in areas where you’ve seen roaches

This keeps your space clean & makes it less inviting to pests.

Can Lemon Juice Kill Roaches?

No, lemon juice won’t kill cockroaches. It lacks the chemical properties needed to harm them physically. For effective roach elimination, it’s best to use insecticidal sprays, gels, or professional pest control services.
