Be sure to sprinkle in dark, damp areas, too, like under bathroom and kitchen sinks, behind washers and dryers, and around the refrigerator, and behind appliances. Do not use in areas where small children or animals play, sleep, or eat. You can make your own insecticide by mixing equal parts of baking soda and powdered sugar and setting up a mock bait plate for the roaches. After mixing your sugar and soda, eave the mixture in a shallow dish where roaches have been seen or are known to travel. The combination of sugar and soda is lethal to the cockroach.
Roaches hate the taste of bay leaves.
You can naturally and safely keep most roaches at bay by placing the leaves anywhere you've seen roaches moving. Using bay leaves is a great way to keep roaches out of the rooms and play area of children. Cockroaches can survive for months without eating, but they need a daily source of water to thrive. Never leave water in the sink, in dirty dishes, or other areas of the house. Check other sources of water as well, such as leaky plumbing, under-refrigerator dampness, and concrete sweating.
