Bottle flies usually breed or lay eggs in or around

• A. Decaying fruit
• B. Water
• C. Animal carcasses
• D. Garbage

Answer: (C)

Bottle flies are drawn to decaying animal matter and use it as a breeding site. They lay eggs on carrion or exposed animal tissue, and the eggs hatch into maggots that feed on the decaying material. Because of this behavior, animal carcasses are the most typical place for bottle flies to breed or lay eggs. Decaying fruit is usually associated with fruit flies, not bottle flies; water isn’t a breeding site, and while garbage can harbor flies, the primary breeding substrate for bottle flies is carrion. In pest control, removing dead animals promptly and maintaining good sanitation disrupts their breeding cycle.
