How can one get rid of roaches at office or home naturally?

The best way to get rid of cockroaches naturally is to create a "cockroach" bait. To do this you will need to make a mixture of 2 parts boric acid - found at hardware stores and pharmacies, 1 part sugar and 1 part flour. Roaches are naturally attracted to sugar as it is a favourite food source. Many people have concerns in using boric acid, and while it is not harmful to humans in small quantities such as this application, it should be kept away as much as possible from small children and pets.
