30 Best Ways to Kill Cockroaches: Full List
1. Baking Soda and Sugar Trap
Mix baking soda with sugar and place it where cockroaches are active. The sugar attracts them, while the baking soda reacts inside their digestive system, making this a simple and effective way to remove cockroaches from home.
2. Boric Acid
Boric acid is a highly effective cockroach killer that dehydrates roaches when they come into contact with it. Sprinkle a thin layer in dark, damp corners, behind appliances, and under sinks for effective cockroach treatment.
3. Diatomaceous Earth (DE)
Food-grade diatomaceous earth is a natural pesticide that damages the cockroach's exoskeleton, causing dehydration. Sprinkle it around entry points, kitchen cabinets, and under appliances for the best results.
4. Vinegar
Although vinegar doesn't kill cockroaches directly, it works as a natural cockroach repellent. Clean kitchen counters and floors with a vinegar and water solution to remove food residue that attracts roaches.
5. Onion and Borax Mixture
Prepare a paste using chopped onion and borax. The onion attracts cockroaches, while the borax poisons them, making it an effective homemade cockroach treatment.
6. Liquid Dish Soap and Water Spray
Mix liquid dish soap with water and spray it directly on visible cockroaches. The solution blocks their breathing pores, killing them instantly.
7. Bay Leaves
Crushed bay leaves act as a natural cockroach repellent because of their strong aroma. Place them inside cupboards, pantry shelves, and food storage areas.
8. Lemon Juice
Cockroaches dislike the fresh citrus scent of lemon juice. Mopping floors with lemon-infused water helps repel roaches while leaving your home smelling clean.

Place coffee grounds inside a jar filled with water to create a simple cockroach trap. The aroma attracts roaches into the jar, where they become trapped.
