There are two other components that are sure to keep these insects away: sugar and baking soda. These two components can be dissolved and combined with water to make a pasty mixture that can be placed in handy locations outside the home.
Although sugar attracts cockroaches, baking soda poisons them instantaneously and kills them.
Finally, we offer one more wholly natural solution. A solution of water and Marseille soap can be sprayed in the vicinity of windows and doors. You won’t get cockroaches in your home anymore because of the stench.
