What is a sign of pest infestation?

• A. Dark brown egg casings
• B. Clean counters
• C. Freshly mopped floors
• D. No droppings

Answer: (A)

Pest activity is evidenced by physical signs that show pests are present and reproducing. Dark brown egg casings indicate that pests have laid eggs in the area, meaning a population is or will soon be establishing itself. This is a stronger and more direct signal of infestation than cleanliness cues like clean counters or freshly mopped floors, which don’t prove pests are nearby. No droppings could simply mean there’s no waste at that moment, not that pests aren’t there. So the presence of dark brown egg casings is the clearest sign that an infestation is underway and warrants prompt action such as investigation, cleaning, sealing entry points, and contacting pest control.
