If teenagers put a listening device(bug)in your home gotten from the internet, where would they hide it?

The house was new with no furniture inside at the time it happened
and all obvious places like above door and window mouldings, edges of baseboards and some outlet and light switch boxes have been checked. It is a one story split bedroom design with a bonus room upstairs. It has all hardwood, tile and low berber carpet and 9ft. ceilings except the greatroom which has vaulted. No ladders were accessible. Shelving is open wire type. I was told it would be very small but is audible and clear as far away as ten miles.
