That is a beautiful plant.
There usually aren't too many flying insects inside a house so I'm just gonna jump in because of something I know about attracting insects at night. If it is not too cold where you live you might try hanging the plant outside in the evening with the porch light shining on it. Insects will be attracted to the light and some will met their doom in the pitchers. This does not need to be done every night; just on the nights when the weather cooperates.
In larger pet stores they sell crickets and flightless fruit flies. You could purchase some of those and drop a few into the pitchers during the winter months when the plant must stay indoors.
Good luck and keep us posted with photos as the plant grows.
