A pesticide label lists German cockroaches and permits use in commercial kitchens only as a crack-and-crevice treatment in nonfood areas. It also states, "Do not apply to food-contact surfaces." A technician proposes spraying a stainless-steel preparation counter at half the maximum rate after all food is removed. Which conclusion is correct?
Correct answer: B - The use is prohibited; reducing the rate does not authorize a food-contact surface

Correct answer: C - Delay application until the air is mixing and all label conditions are met
An office has brown-banded cockroaches inside warm, dry electronics cabinets mounted high on the walls. Both an emulsifiable-concentrate spray and a gel bait are labeled for the site. Which plan best matches the pest's harborage and minimizes solvent and overspray concerns?
Correct answer: D - Place small gel-bait spots by elevated harborages and inspect adjacent electronics

Eight days after a targeted bed bug treatment, monitors contain no adults. On day 10, an inspection finds two unfed first-instar nymphs beside fresh, empty eggshells near the headboard. What is the best interpretation and next step?
Correct answer: D - Protected eggs likely hatched; reinspect and complete the scheduled label-compliant follow-up
