7. “ Bedbugs hide in cracks and crevices during the day and come out at night to suck blood. Hence, DDT spray must be directed toward their daytime hiding places. Apply the DDT spray to the bedsteads, paying particular attention to cracks in the wood and joins. Spray the springs and mattresses. Strip the mattress and spray all sides and the edges, especially any crevices in which bedbugs might hide and behind any loose paper where they might congregate ”.
42. Where to Look - Most Everywhere It can take 1-2 hours to thoroughly check a space for bed bugs. Be thorough! Light infestations are extremely difficult to detect.
62. Pesticides - THE LABEL IS THE LAW Currently, non-chemical products and techniques are incapable of efficiently or quickly controlling or eliminating established bed bug populations. Precise placement of a suitably labeled, registered and formulated chemical insecticide is still the most effective bed bug control. The choice of chemical products and specific application techniques can depend on many factors, including the physical location and structural details of the bugs ’ harborages, the product’s labels (which can vary by political jurisdiction), the immediate environment, and local or national laws.
