A friend of mine on Kauai just had his house tented by a company (I don't know which one but Orkin advertises this option) that uses heat to kill the termites. A quick glance on the internet says you need to get your couch to 120 degrees for 35 minutes to kill them all. Another quick glance on the internet says that on an 80 degree day the inside of a closed car can reach 130 to 172 degrees. If you know somebody with a pickup truck with a canopy that will fit your couch, parked in the sun for an afternoon may solve your problem.
ETA: Or maybe an attic (typically 150-160 degrees, though I bet a steel roof variety directly on rafters like most of Puna gets hotter).
