Without a doubt, these are some of the most hated insects on the planet. They emerge from the corners, lurk in your kitchen, and there are even certain species that have the ability to fly.

Considering that some studies have concluded that cockroaches can survive a nuclear explosion, you might think there’s no way to stop them. However, you’ll be glad to know that it’s not the case.

And so, boric acid is the best solution to this problem. Additionally, it’s easy to obtain and very affordable.

This product also helps eliminate ants and you can find it at the pharmacy and even the grocery store. Use it sparingly and in select areas, especially if you have children and pets.

Take half a cup of water (100 ml) and mix it in 2 tablespoons of boric acid (20 g). Then, soak a piece of bread in this mixture and place it in areas where you see cockroaches.

Another option is to mix three parts of boric acid with one part sugar and sprinkle it around your kitchen or bathroom (in corners, cracks, behind the furniture, etc.).

Sugar will be the bait to draw your prey and the borax will kill it.
