I didn't find the critter in the ductwork, however I did see some poop

A man called me because he thought that he heard noises in the ductwork, and a lot of times noises in the ductwork can be explained by the movement as well as shifting of the ducting itself, then just because you hear noises in the ductwork, does not mean that you have a problem with mice or rats or other indoor vermin, but my company handles lots of heating as well as cooling system repairs as well as I’ve only seen infestations a few times, however each 1 of those times was a separate opportunity that was even worse than the first.

When I received a call from the residential customer, I knew that he was expecting me to evaluate the ductwork, then i took all of the items necessary to handle the task.

I have a special camera at the end of a flexible stick as well as I use that camera to view the inside of the duct work throughout the house. It’s a wonderful way to see inside of the ductwork without taking anything apart. I searched all over the duct work for several hours. I did not see any evidence of mice or rats someplace, however I did see some evidence of droppings. It’s difficult to tell if those droppings are outdated or new, so I told the owner of the lake house that he should call an exterminator just to be safe if he was feeling worried. I didn’t want to be wrong about the mice or rats, however I was pretty certain that he did not have an infestation, the noises honestly came from the cooling system or creaking floorboards in the house.
