I never fully got rid of them but they survived better in damp climates so after my initial big freak out clean, I only found the odd ones here and there and kept the house as well ventilated as I could.

As you have been freezing everything and had new bags open etc, it sounds more environmental. We have had some very hot weather over summer and having windows open etc, all sorts can get in.

It's unlikely they would "bite" Percy to make him itchy, hamsters do itch like all animals, is it possible you are on high alert and it seems like he is itchier and thus worrying you?

Hope you get it sorted, all the best

Hmmm, not come across those - thank you - I'll investigate! He's in a Detolf so glass sides but a thoroughly airy mesh lid, and we live in a new build so I don't think it's generally damp - but that said, when he came to us 3 weeks ago, he spent the first fortnight curled up in his new house and was peeing in there so it probably was a bit damp and ripe!! I haven't seen these bugs on any other part of his enclosure but in his bedroom and stash corner which makes me think they have to be on - or attracted to - his stash of cereal or on him himself. Then again we do have old books in the house so I will definitely be looking into that! Thanks for the tip!
