A common prevention for carpet beetles is

• A. Spraying insecticide on carpets daily
• B. Damp-mopping floors after each use
• C. Storing items in sealed plastic bags
• D. Vacuuming weekly with a sealed bag

Answer: (C)

Carpet beetle prevention focuses on cutting off access to their food sources, especially natural fibers like wool, fur, and feathers. Sealing items in plastic bags creates a strong barrier between those fabrics and any beetles, eggs, or larvae that might be nearby. This simple, long-term step keeps susceptible textiles protected during storage and reduces the chance of an infestation taking root in things you don’t wear or use regularly.

As for the other ideas, spraying insecticide on carpets daily isn’t a practical or targeted prevention strategy for fabric pests and can lead to unnecessary chemical exposure. Damp-mopping floors after every use doesn’t address the fabrics themselves, which are the beetles’ main food source. Vacuuming weekly with a sealed bag helps remove any existing pests and remnants, but sealing items provides a preventive block that stops new infestations from starting in the first place.
