Oh you poor soul. I'll bet that sucker is just chirping all night and keeping everyone awake. If you really know which duct that pest is in and how close it is to the vent, you might try spraying pesticide into that duct. Turning the furnace on won't do much I think.

weeks, if not forever. the furnace won't make any difference, except to the speed with which it chirps.
Running the furnace for an hour will probably kill every insect living in there. They can't take high heat for very long.
