I'm am far from a BP expert, but I have found that this definitely works with my BP.
Try making sure that it's warm enough. I thaw mine in warm/hot water to the point where they are 100% thawed and actually warm enough to emit heat when I touch the mouse/rat.
If they are too cold, like the water was too cool, my snake will sniff it but otherwise ignore it. If the F/T is not warm enough, it ignores it. Once its warm, do the zombie dance and mine has never missed a feed in the half year I've had it.
