1. Kill Roaches With Baking Soda and Onions. Let's begin with one of the quickest, easiest, and most “make it right now!” home remedies for roaches – baking soda and onions, both of which you may already have in the fridge. Dice a handful of onion, sprinkle it with deadly baking soda, and voila!

Vinegar is a natural household ingredient that can repel and kill cockroaches. Fill a spray bottle with equal parts vinegar and water, and then spray it directly onto the roaches when spotted. The strong odour and acidity of vinegar can be effective in eliminating them instantly.
If cockroaches get enough borax on the outside of their bodies, it actually damages their exoskeletons. This causes them to rapidly dehydrate and die; a thick coating of borax will certainly get rid of roaches overnight.
Citronella
Citronella not only works great for repelling mosquitos but also cockroaches. While the candles don't work well against roaches, you can use citronella oil as a deterrent. You can mix it with water and use it as a spray or simply wipe down areas with the diluted mixture.
All About Vinegar
Unfortunately, it doesn't actually kill these problem insects. It's more of a cleaning tool than anything else, and it won't actually help eliminate your roach problem. It can, however, help deter roaches and get rid of germs in the kitchen when used as a cleaning agent.
In that scenario, you can buy what are called desiccant dusts—like diatomaceous earth, a non-toxic substance you can find on Amazon—and that will dehydrate the eggs, thereby killing them.
Boric Acid
It's extremely toxic and can kill multiple generations of roaches. Mix a combination of equal parts of boric acid, sugar and water to make a dough.
Sprinkle the diatomaceous earth around areas where roaches travel and frequent. The sharp particles of diatomaceous earth damage the waxy, protective exoskeleton of the roach, causing it to dehydrate and die, typically within 48 hours of contact.
Spray roaches with insecticide or a concentrated liquid roach killer to kill them on contact and deter them from the area. Try dusting diatomaceous earth or boric acid along cracks and crevices to use them as natural pesticide powders.

Many bugs hate citrus smells and cockroaches are no different. You can use lemon juice and put it in dishes to ward off those pests. You can also take lemon peels and place them around your home where you might think the cockroaches are hiding.
The sugar attracts the cockroaches while baking soda will kill them. Once they eat it, baking soda will react badly by creating gas inside of the stomach and cause its stomach to burst. All you have to do afterwards is just clean up the dead roaches.
Cockroaches will eat soap, so it is not toxic to them. However, if you cover them sufficiently with a soapy solution, it will disrupt their ability to breathe through their spiracles and they will suffocate. So yes, Dawn soap will kill a roach when used correctly and accurately.
