Roaches are one of the most common pests, and they can be very difficult to get rid of. If you have roaches in your home, you may be wondering how to make a homemade roach killer. There are a few different options that you can try, and we’ve outlined some of the best ones below.

Boric Acid

Boric acid is one of the most effective ingredients for killing roaches. It works by dehydrating them and causing them to bleed to death. To use boric acid, mix equal parts boric acid and sugar. The sugar will attract the roaches, and the boric acid will kill them. Once you’ve mixed the ingredients together, put them into a shallow dish and place it in an area where you’ve seen roaches.

Diatomaceous Earth

Diatomaceous earth is another effective option for killing roaches. It works by puncturing their exoskeletons and causing them to dehydrate and die. To use diatomaceous earth, sprinkle it in areas where you’ve seen roaches or where you think they might be hiding. You can also put it into shallow dishes and place them in these areas. Just be sure to use food-grade diatomaceous earth, as other types can be harmful to humans.

Soap and Water

A simple soap and water solution can also be effective at killing roaches. The soap will suffocate them, and the water will drown them. To use this method, mix together equal parts soap and water in a spray bottle. Then, simply spray any roaches that you see with the solution. You can also spray areas where you think they might be hiding, such as behind appliances or under furniture.
