Worried about P. scabers in reptile and enclosures.

I am very new to the isopod community and keeping them with other animals. I recently acquired some porcellio scabers from a reptile expo as these were recommended for all the animals i have. Ball python, leopard gecko, corn snake, and giant African millipedes. But im getting worried about having them in these tanks because i have read that they can be very protein aggressive. In especially worried for my millipedes because they could potentially be more vulnerable than my reptiles. Any advice on if i should remove them completely from all tanks or just add an abundance of protein sources?
