All you have to do is mix together about three tablespoons of boric acid and the yolk from one egg. Stir until the mixture forms a thick, dough-like consistency. Next, use a spoon to make balls from the mixture and place them on a piece of wax or parchment paper. Leave them sitting out to dry for an hour or so.

Once the balls are hard, place them anywhere you’ve seen roaches in your home. Remember, roaches are attracted to cool, dark, and damp places, so these are the areas you’ll want to target.

The roaches will eat the solution and die shortly afterwards. It’s important to note that if you have pets or small children, you’ll want to ensure these dough balls are far out of their reach so they don’t accidentally consume them.

You may have to repeat this method one more time in case the female cockroaches have laid eggs. But after one to two cycles, your home should be completely free of nasty cockroaches!
