Cockroaches are among the most dreaded household pests, hiding in dark, damp spots like under sinks, basements, and closets. Spotting even one often signals a larger infestation, prompting many to seek quick, affordable solutions without calling professionals.

One simple DIY method uses two common ingredients: boric acid and egg yolk. Boric acid acts as a poison, while the egg yolk attracts roaches, creating an effective bait easily made at home.

To prepare the bait, mix 3 tablespoons of boric acid with one egg yolk until it forms a thick, dough-like consistency. Shape the mixture into small balls using a spoon and place them on wax or parchment paper to dry for about an hour. Once hardened, they’re ready for use.

Place the bait balls strategically where roach activity is noticed—under kitchen and bathroom sinks, behind appliances, inside closets, or along basement edges. These locations help ensure roaches find the bait and carry it back to their nests, improving effectiveness.

Use caution: boric acid is toxic if ingested by pets or children, so place bait out of their reach. Monitor the situation and repeat the process after a couple of weeks to target remaining roaches or eggs.

This homemade roach bait offers an easy, affordable, and effective way to tackle infestations. With careful placement and use, it can provide lasting relief from one of the most persistent household pests.
