What is the most obvious problem associated with large roosts due to debris accumulation?

• A. Accumulation of debris that attracts insect pests such as dermestids
• B. Increased noise
• C. Air pollution
• D. Spread of seeds

Answer: (A)

At the heart of this question is how debris from large bird roosts creates a ready-made environment for pests. When many birds roost together, they generate a lot of debris—feathers, droppings, and nest material. That debris becomes a food source and habitat for insect pests, especially dermestid beetles, which thrive on dried organic matter. Once these pests establish themselves in the roost or nearby structures, they can cause odors, contaminant buildup, and damage to materials stored in buildings, making this the most obvious and direct problem. Other issues like noise or seeding spread aren’t tied as directly to the debris itself. The debris-driven pest attraction is the immediate consequence that often drives cleanup and exclusion efforts after establishing large roosts.
