Homemade Cockroach Killer

When roaches infest your home it can cause embarrassment. If you want to keep pesticide chemicals out of your home, you can make your own roach killer to effectively kill the pests. Homemade solutions can control and prevent the roaches from invading your home effectively. A single female roach can carry up to 40 eggs, which can cause the infestation to spread if you do not kill the roaches immediately.

Combine 1 cup of cool water with 1 tsp of dish soap in a bowl.

Stir the water and soap gently to prevent forming suds.

Pour the solution into a spray bottle.

Spray the soap and water solution directly onto roaches.

Combine 2 tsp of boric acid with an equal amount of water and granulated sugar.

Stir the ingredients until a paste forms.

Place the boric acid solution near a location where the roaches reside. Sprinkle it around the area and the roaches will eat it and carry the solution back to their nests.


If you have a large roach infestation, you may need to hire a professional to remove them.
