9 week old bp not eaten for 3 weeks help, newbie owner

[200xth]

Hi ,
he has eaten twice for the breeder b4 I got him and twice for me. He is now refusing small fuzzies, hoppers and even rat pups. I have even warmed them with a hairdryer and pierced the brain but he just looks interested then leaves it. I have left them overnight too. He is 100g. Please help I am getting worried. He is in a 10litre viv 2 hides foliage and water as recommended

Try live for a while.
