Can flies lay eggs on hamsters and what happens to the hamster if they can and hatch?

Yes, certain types of flies, particularly blowflies, can lay eggs on hamsters. If the eggs hatch, the larvae (maggots) can infest the hamster, potentially leading to serious health issues such as infections, tissue damage, and even death. This condition, known as myiasis, can cause significant suffering for the animal and requires prompt veterinary attention to treat effectively.
