Hello and welcome! Sounds like your baby is stressed from husbandry, other keeps have their beeps in the same room as their rodents, so they can probably lend better advice on this.How are you measuring temps? Digital thermometers / hygrometers? Is there a water dish? Do you have a temp gun? Are you regulating his UTH with a thermostat? Is he in a high traffic // bright room?
You need ot measure the hot spot, and cool spot with a temp gun, and get something like an accurite thermometer/hygrometer to measure ambient temps. 75-82 ish is good for ambient temps.
Every beep is different, though maybe try a "cave" hide. Reptile basics make a great inexpensive hide, or exo-terra also make great hides.
From what I understand, Beep's don't hear like we do, they feel vibrations.
Pinkies are too small for a BP, your little guy should be on a hopper mouse or adult mouse. How are you heating / warming up the food item?
Take a peek at this, good tips here
