The act-rites are usually in the section by the lightbulbs/ air conditioner thermostats. but I have seen in them in a bunch of other places as well (outdoor section, paint section, etc.)

in the wild BP's are nocturnal... during the day they stay in rodent burrows or termite mounds, then come out to hunt at night. because of this day/night cycles really aren't necessary. Bp's love dark hides that are nice and snug... That isn't to say that they are bad, but your BP will be fine without one. I use fluorescent lights for viewing on a 12 hour schedule.

Make sure that your tank isn't directly in front of a window, as the tanks can act like a green house and get really hot.
