Which of the following is an example of pests that non-residual pesticides would be considered for?

• A. Bed Bugs
• B. Termites
• C. Flies (adult stage)
• D. A bicycle shop

Answer: (A)

Non-residual pesticides are used when the goal is rapid elimination without leaving a lasting chemical residue in occupied spaces. Bed bugs fit this scenario well because they hide in mattresses, seams, and furniture, where leaving a long-lasting residue would be undesirable for people sleeping there. A quick-contact spray can kill exposed bed bugs right away, and this approach is often used in combination with cleaning, encasements, and other integrated methods. In contrast, termites need a persistent barrier to protect against reinfestation, flies (adult stage) are typically handled with methods that may involve ongoing control, and a bicycle shop isn’t a pest. So bed bugs illustrate the kind of pest treated with non-residual products.
