I wasn't doubting that they would germ and grow a tap, I was saying that if left up there, they would languish in the heat of that box. I was commenting on the yellowing and shriveling of the tap that you had reported. It would be okay, I think for a day or two, but after that, I believe the same results would happen as you reported before. As long as you're not covering the vents of the cable box, they're designed to stay under 100 with an ambient temperature of up to 85*. If you cover the vents inadvertently, though... that box will get up there quick... almost 140 in just a few hours.
