Prolly start by turning off the heat so u dont cook it.. The. Put a rat by the vent it went imams a heat lamp/mat.. If u know the routing of the ducts u could give him access to get out at all of them..
U can also rent root rooters with camera ends from home depot so u can fish it in and find them then go an get into the vent
Well, I've had the lamp on for over an hour now. If only my patience wasn't so thin. Heat has been off since I found out about it. I don't know how to create an opening for her to get out of, because everything is bolted together in the basement. But I do have a rat in a cage sitting right at the opening.
Well, she might have gone a lot deeper than we thought. It's hard to get through because all the plumbing and stuff was built after the heat was put in. Old old house. Still digging, though. Any other recommendations?
