Finicky female

Hey everyone, I have a 6 month old female ball python that I bought from NERD on april 29th. She hasn't eaten yet, and I have tried 4 times with f/t. She wasn't interested the first two times, and now she seems interested and even tried striking, but won't eat.
She is in a rack system with the hot end at 86-90 and the cool end ranging from 80 to 83, with humidity between 50 and 60.
She is only interested in the mouse when i dangle it for her, but even then she rarely strikes and doesn't strike well when she does. This makes me think she might eat a live mouse, but I don't think there is anyone near me who sells live mice except for petco. Would petco mice be free from parasites? I'm in worcester, ma, which is far away from most breeders.
Any suggestions?

Live would be the next best bet.

Petco mice are for the most part clean, but are rather expensive.

Another thing you could do is provide her with a hide if you haven't already, and dangle and wiggle the FT mouse in front of the entrance.

she has a hide, and I spent a chunk of last night dangling in front of the hide. She struck at it once or twice, and I left the mouse in front of her hide but once it stopped moving she stopped being interested.
