All About Vinegar

Distilled vinegar does not kill or repel roaches, making it completely ineffective. Distilled vinegar will help keep your kitchen clean, giving cockroaches less to snack on. However, roaches can live for months at a time without any food at all, and they will eat almost anything to survive.
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.

Bleach's Effect on Roaches

Home remedies like diatomaceous earth, baking soda, boric acid, citrus, essential oils, and borax can be effective ways to get rid of roaches. If you want to take a more aggressive approach to eliminate roaches, glue traps, bait stations, and liquid roach deterrent concentrates are all excellent options.
Baking soda can kill roaches, but in order to do so the roaches have to eat the baking soda mixture, and once they consume water the baking soda reacts with the water creating gas in their stomachs, which kills them.
Baking soda and sugar
