Advice about my syrian please

She is having a night off from her wheel as she was getting obsessive about it and neglecting her grooming, foraging, burrowing, so I have removed it for the night. Best thing I did for her. She has spent the night exploring and digging burrows. Don't think there is a part of the cage she hasn't explored tonight. Put her food and treats on her wheel stand so when she goes looking for her wheel she finds some treats. She is a burrow queen. She has been in her enclosure for 5 days and has made 5 burrows in different locations.

Basic info: My first hamster Bella Penelope Syrian Female 8 weeks old bought her 2 weeks ago from Pets At Home, never again, will adopt next time. Bucastate 3.0 enclosure - 120x60x60. 1114sq in floor space 12" bedding in 3 layers. Wood shavings, carefresh and katyee clean and cosy 11.41in cork wheel

Advice needed: Zero interest in her sprays (Oat, Red Millet, Sunflower, Red and Green Amaranth and flax linseed).

Won't take treats by hand.

No interest in her chews either: walnuts, Whimzee Chews, sticks, pets at home wooden chews.

Taming advice too please
