How to Kill a Cockroach: Proven Methods

There are several ways to eliminate cockroaches effectively. Here are the most reliable strategies:

1. Using Cockroach Baits

Cockroach baits are one of the most effective ways to kill these pests. They contain slow-acting insecticides that attract cockroaches, which then carry the poison back to their nests, spreading it to others.

• Where to Place Baits: Place baits in high-traffic areas such as under sinks, near garbage bins, and behind appliances.
• Benefits: Baits target the entire colony, not just individual cockroaches.

2. Applying Insecticides

Sprays and powders designed specifically for cockroaches are widely available. They work quickly and are ideal for immediate results.

• Insecticide Sprays: Use contact sprays to kill cockroaches on sight.
• Insecticide Powders: Powders like boric acid are long-lasting and effective when applied to areas where cockroaches crawl.

3. Setting Traps

b. Diatomaceous Earth

• Food-grade diatomaceous earth damages the exoskeleton of cockroaches, causing dehydration and death.

c. Baking Soda and Sugar
