Hi, welcome to the forum!
There are a few different things at play here that are likely stressing your BP:
1) Pinky rats are too small for a BP his age. He likely struck at you because he's hungry. A BP should be fed prey that is approximately the width of its body and around 10-15% of its body weight. Here is a recommended feeding chart for reference:
2) Temps too high as previously stated, you need to get a thermostat hooked up asap if you don't already have one.
3) Humidity is a bit too low. If you have trouble keeping up the humidity it helps a lot to cover most of the screen top (assuming you have a glass tank with a screen top) with aluminum foil and to scatter some damp sphagnum moss around the enclosure. You can also add a humid hide on the warm side of your tank so your BP can choose to go in there when he needs some extra hydration (especially when shedding!). Here's a tutorial on how to make a humid hide (very simple and can be done with stuff you have in your house): https://www.youtube.com/watch?time_c...&v=kS8gZXXK7S4
