You can get rid of an infestation.

Homemade Roach Killer: Effective and Super Easy to Make

Homemade Roach Killer

Finding an effective roach insecticide can be challenging. Household owners who encountered such a problem can attest to this.

It is almost impossible to eliminate them. Hiring the services of a professional exterminator can cost you a good sum of money.

But it doesn’t mean you can’t do anything about it. Several homemade roach killers are proven to work really well. They are not only cheap but also safe to use. In addition, the elements needed are easy to find.

Baking Soda Roach Killing Ball Baits

Our goal here is to make cockroach baits. This option is not complex, mainly because all the ingredients are ubiquitous. For example, baking soda can be found in almost every household because of its many uses. It may seem hard to believe, but the baking soda you use for baking and cleaning is also a potent ingredient for killing roaches!

You may be wondering how baking soda could kill roaches. Well, there is a pretty simple explanation for that. Have you ever tried pouring baking soda into a cup of water? The natural reaction of baking soda and water is a bubbling effect. When the roach eats a piece of the baking soda ball bait that you made, and then the roach drinks water, what happens inside the roach’s stomach is the bubbling effect that causes the roach’s stomach to burst and die.

Baking Soda Roach Killing Ball Baits

Follow these simple steps:

  1. Gather the ingredients.
    • 2 tablespoons of baking soda​;​​​
    • ½ tablespoon of confectioner sugar, this is what attracts roaches to eat the ball bait;
    • 2 tablespoons water, this will glue the baking soda and sugar together.
  2. Get a container enough for your mixture. Set aside.
  3. Get another container for the baking soda and confectioner sugar. Mix it well.
  4. Pour the mixture into the bowl with water. Do this in small portions to avoid lumps. Mix it well, then knead between fingers.
  5. Prepare a bond paper. When you have achieved a certain consistency with the mixture, roll the mixture into tiny balls with your fingers. Place balls on the bond paper to dry.
  6. Put the ball baits in places where you suspect roaches frequently and repeat this for a week or until such time you don’t see any roaches anymore.

Boric Acid Roach Killing Paste

Boric acid contains Boron and is considered a pesticide. Given this fact, it is still important to be cautious when you opt for this roach-killer recipe option, especially when you have kids or even pets. However, on the brighter side, while this is classified as a pesticide, it doesn’t carry as much risk as those roach-killer formulas found in stores.

In making the paste, you will need the following:

  • 3 teaspoons boric acid;
  • ½ teaspoon used cooking oil, preferably with food residues from frying as this will attract roaches;
  • 3 teaspoons water.

Mix the ingredients into a small container until the mixture is smooth. Once you have achieved the smoothness of the paste, you can apply this in areas where you usually see cockroaches.

You may have to spray water on the paste once a day to keep it moist and attractive to roaches. Roaches become dehydrated when they can eat some of the paste, which causes their death.

Spice Roach Spray killer

Spice Roach Spray killer

Powdered spices like garlic, onion, and cayenne pepper are great ingredients for a roach spray killer. Natural chemicals in these spices make them natural repellents. If you add any of these to the dish soap mixture will make a perfect deterrent from roaches. Unfortunately, when the roach is sprayed with the solution, it results in the clogging of pores that disables the roach to breathe. So it is only a matter of time before it dies.

​Prepare the things you will need:

  • Spray bottle;
  • 1 tablespoon of dish soap;
  • 1 cup of water;
  • ½ teaspoon of powdered spice.

Pour the cup of water into the spray bottle. Add the teaspoon of liquid soap and shake to mix the solution well. Add the powdered spice and shake again. You now have a roach spray killer. Spray it on every roach you see.

What are other tested solutions to stop roach infestation?

Common herbs you have in your kitchen. Yes, you read it right, and some of these are catnip, bay, and mint leaves. All you need to do is chop the leaves to release the leaves’ natural moisture and scent. Then, put it in areas where cockroaches hang out. They will go away because they hate the smell of the herb.

Mouthwash. If your mouthwash has more mint content, the better. Roaches are not fond of mint odor, so if you mix this with water and detergent, you instantly have a roach-repellent spray.​
