As a bait, borax is mixed with a food attractant such as sugar and placed on places frequented by the said insects while scavenging. Cockroaches are later on drawn to the trap and eats the bait along with the insecticide (borax).
Borax is deadly to roaches once they ingest it, but it doesn't lure roaches on its own. To entice them, add sugar to the mix—the roaches won't pick up on the borax and will ingest the mixture happily. Combine sugar and cocoa powder for another sweet trap.

In addition, boric acid doesn't affect cockroach eggs. Although adult roaches may respond to treatments, their young often remain safe in hard-to-reach spaces to grow and multiply.
Borax is a readily-available laundry product that's excellent for killing roaches. For best results, combine equal parts borax and white table sugar. Dust the mixture any place you've seen roach activity. When the roaches consume the borax, it will dehydrate them and kill them rapidly.

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.
Cockroach predators include mammals, avians, amphibians and other reptiles. For example, hedgehogs will eat roaches. Joining the roach à la mode dinner party are geckos, skinks and other species of lizards, frogs, turtles, some types of birds and even rats and mice.
While the National Library of Medicine (NLM) classifies borax as being noncarcinogenic, it does pose some risks, including: skin, eye, and respiratory irritation. digestive problems. infertility.
Dr. Robin Jacobson, a pediatrician at NYU Langone Medical Center, warns families to stay away from the white powder altogether. "Borax can cause burns, especially when you touch it multiple times," she says.
First, make sure to keep it away from children's reach. Second, avoid using it as a cosmetic product and handle it with care at all times. This usually means wearing a mask and gloves when using it. Finally, do NOT mix Borax with any boric acid products, such as pesticides.
