Roaches, or cockroaches, are insects that can become a nuisance when they take over your home. There are more than 4,000 different species of roaches. The types that infest homes are attracted to the warm environment. A female roach can hatch up to 40 eggs at a time. Fortunately, there are effective, homemade remedies that can stop the infestation and kill the roaches in your home.

Boric Acid

Boric acid is one of the most commonly used homemade roach killer. It was first registered as an insecticide in 1948. When roaches eat the boric acid, it makes them become dehydrated, which will eventually kill them. The ones that eat it will typically bring some back to their nest, on their feet or body, and introduce it to the rest of the family. To make a homemade roach killer, mix 2 to 3 tsp. of boric acid with equal parts of sugar and water to make a paste. Put it in the areas where roaches normally reside, and sprinkle it around the infested areas of your home. This method will eliminate roaches within two weeks.

Baking Soda and Sugar

...

Baking soda is a useful product to have in your home. It is commonly used as a non-toxic roach repellent. It works similar to the boric acid. Mix equal parts of baking soda, sugar and water. Use the paste as a bait around the areas that roaches typically make their home--under the cupboards, alongside the refrigerator and around kitchen sinks. The baking soda will kill the roaches that eat it, and stick to their feet so it's carried back to the nest, where the others will eat it and die.

Soap and Water

...

Another simple, effective method of killing roaches is with soap and water. Mix 1 cup water with 1 tsp. of soap. Pour the solution in a spray bottle, then spray it on roaches. The soap solution will suffocate them as the suds block their pores and prevent breathing. Use this homemade roach killer as often as needed. You may also leave a jar of water near the corners that they frequently visit. When they crawl into the jar, they will not be able to escape.
