I can handle a lot of things, but cockroaches? Absolutely not. These creepy pests love hiding in damp, dark corners like basements, closets, and under kitchen sinks—basically, all the places you least want to find them. If you’ve spotted even one scuttling across your floor, you know how unsettling it feels. The good news? There’s a simple, inexpensive hack that can wipe them out fast.
The Easy Homemade Roach Killer Recipe
All you need is one egg yolk and about three tablespoons of boric acid. Mix them together until you get a thick, dough-like paste. Then, use a spoon to roll the mixture into small balls and place them on a piece of parchment or wax paper. Let them sit out for an hour until they harden.

How It Works
Once the balls are ready, place them in areas where you’ve noticed cockroaches. Focus on damp, dark hiding spots like under sinks, in closets, basements, or behind appliances. Roaches will be drawn to the mixture, eat it, and die shortly after. Just make sure to keep these out of reach of kids and pets, as they can be harmful if consumed.
The Final Step to a Roach-Free Home
You may need to repeat the process once more if female roaches have already laid eggs. But usually, after one or two cycles, you’ll notice a dramatic difference—and eventually, a completely roach-free home.
This simple hack is cheap, effective, and doesn’t require hiring an exterminator. With just boric acid and an egg yolk, you can finally say goodbye to those nasty pests for good.
