What is the recipe for egg yolk and boric acid for roaches?

To create a roach bait using egg yolk and boric acid, mix one egg yolk with about one tablespoon of boric acid until well combined. You can also add a bit of sugar or water to make it more appealing to the roaches. Place small amounts of this mixture in areas where you’ve noticed roach activity, ensuring it's out of reach of pets and children. This bait attracts roaches, and the boric acid helps eliminate them when ingested.
