Critters in the Duct Work

Q. Hello, I have a 1995 singlewide mobile home, and a critter got into the ductwork, is it possible? I would like to know what the ductwork is made of and how a critter could get into it.

A. Yes, anything is possible. If it is the original duct it will more than likely be made of aluminum. Now with that being said I will tell you this. Lots of different critters can chew through aluminum, squirrels for one can do it. On some homes the end runs sometimes are flex duct that will continue on to the last duct at the end of the home. You can take off the register cover and see if it is flex. This flex duct is usually plastic and looks like dryer vent duct. I had a mouse chew through one of the plastic ducts and get in. I replaced it with metal duct. If you have a critter living in the duct work you need to get it out if for nothing else sanitary reasons. After the critter extraction be sure to repair any damaged duct work. I suggest you call your local animal control people to see if they can help. If not you may have to call a critter removal service. Some pest control companies do this type of service.
