Place dabs of the mixture in strategic spots like behind or beneath appliances, in closets, or near wastebaskets. Roaches are attracted to the sugar, and ingest the mixture. The baking soda gives them gas and ultimately kills them.

Get some insecticide that is labeled for use against cockroaches and contains Cyfluthrin or another insecticide as the active ingredient. Spray wherever cockroaches may be hiding or entering the house, including along walls, in cracks, and in vents.
