Sounds more like fae to me. Try getting a package of iron washers and distributing them throughout the house, in every corner. Alternatively you could use hemetite but that could get expensive depending on the size of your home Don't seal off the door or windows. In fact, if you can, before distributing, open a window to give an exit.
You have to understand that there is no true line between low angel/demon, nature spirits, and fae. Its just different cultures using different words to describe and then combining together to create arbitrary separations. Likewise "demons" are mostly pagan gods and true daemon are semi-divine. Higher "angels" can be considered daemon. A daemon or god would not waste his/her time playing with your tv. Fae, however, are vindictive and will put time aside just to mess with you. But they aren't "evil", destruction and mischief is in their nature, so anything positive or "holy" will not work against them. You have to think "anti-magick" or "anti-spirit".
