Other Natural Methods to Kill Roaches

The most popular home remedy to kill roaches is the boric acid bait. If you are dealing with an infestation and you want long-term effects, this might be an ideal solution for you. Putting sprinkles of boric acid on areas where cockroaches typically go can help you eliminate cockroaches. As the powder clings to their bodies, this will kill the roaches eventually. Bonus points if they bring bits of powder to their community. 

However, it would be more deadly if they digest the powder directly. But how will you make cockroaches eat them? It’s simple. Mix the boric acid with sugar and flour to make a dough. Roll them into the balls and then place them in potential areas where cockroaches like to hide. As what have been noted earlier, cockroaches are attracted to sugar. Therefore, the roaches will eat the ball along with the boric acid. When they’re full and have gone home, they die in their nest, and other roaches will feed on them. As surprising as it may sound, yes, roaches will feed on dead roaches. So simply put, you’ve given poison to a roach, it brings the poison home, and when it dies, it dies with its family. 

The downside of this bait is you cannot use it when you have pets or kids at home. But fret not, as there are other ways to kill roaches that will keep your kids and pets safe. One way is instead of using boric acid, and you can mix sugar with baking soda. Same way, the roaches will be attracted to sugar, but as they eat the sugar, they also eat the baking soda. Baking soda is not good for their digestive system, which in turn kills the cockroach in time.

Moreover, you can also repel cockroaches by spraying peppermint oil. Cockroaches don’t like the smell of peppermint, and this is one of the safest ways to repel cockroaches. Spray under the fridge, under the sink, in the cupboard, in the cracks, or other potential places for cockroaches to hide.

More importantly, a tidy home is the best remedy to repel cockroaches. Clutter attracts any pests. So if you want to lessen cockroach sightings, it helps when you keep your house spick and span. If they don’t have any food to eat or any place to hide, your place will not be so much an attraction for them.
