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 sporting goods store

Answer: (A)

Non-residual pesticides are designed to kill pests on contact and do not leave a lasting residue on treated surfaces. They’re best used when you need immediate knockdown in a space that people will occupy soon after treatment, and when leaving pesticide residues would be undesirable or impractical. Bed bugs fit this scenario well because treatment focuses on直接 contact with hiding spots, seams, and cracks where the bugs reside, providing quick results without relying on a long-term surface residue. Termites, on the other hand, require long-lasting residual barriers to protect wood and prevent reinfestation, so they’re not a good fit for non-residual products. Flies in their adult stage can be managed with various approaches, but adult flies don’t illustrate the typical use case as clearly as bed bugs do. A sporting goods store is not a pest scenario.
