How Do You Make Homemade Roach Killer?
It can be very difficult to get rid of roaches, and chemical treatments can be expensive. Make a homemade roach killer with either boric acid or baking soda as well as sugar and water.
Gather your supplies
Use boric acid or baking soda as the base for the roach killer along with sugar and water. You also need a bowl and spoon for stirring.
Make a boric acid paste
Mix 3 teaspoons of boric acid, 3 teaspoons of sugar and 3 teaspoons of water in a bowl. Stir the ingredients thoroughly to form a paste.
Make a baking soda paste
Make a baking soda paste instead. Mix 3 teaspoons of baking soda, 3 teaspoons of sugar and 3 teaspoons of water in your bowl. Stir the ingredients together to make a thick paste.
Spread the paste
Spread the paste that you have made anywhere you typically see roaches. Also spread the paste in areas that you have not seen roaches such as under the stove, under the sink and in cabinets.
Reapply the paste
It can take up to two weeks for the roaches in your home to die from the paste that you have applied. If you see roaches after two weeks, reapply the paste in the same areas. Continue to make and reapply the paste every two weeks until you no longer see roaches in your home.
