My personal favorite solution for cockroaches lies in your kitchen cabinet. In fact, in my case, it is in my spice drawer, and in my back yard. Bay leaves, from a bay tree, is commonly used in cooking due to its pungent and nice smell and flavor. When crushed, these leaves produce a strong fragrance due to the essential oils in the leaves. Leaves can be crushed and sprinkled along baseboards of cabinets, in drawers, or whole leaves can be tied together with string and tied inside closets, cabinets, and drawers.
