Thank you a lot Serendipity, I've been telling that to myself for the last two days but it's hard to convince myself, and it helps to hear it from another person.
So far, so good. No bugs in two days. I hope the insecticide worked. I think that my dad applied too much, the first night after ventilating my room all day it still reeked at insecticide, my parents didn't want me to sleep in my room. Today the smell is almost gone.
I've frozen all the food again except for a little bit for these days and I'm going to leave it in the freezer for another week. And I'm going to stablish a froze/bake protocol for new things
nothing will touch my little hammy again withouth being sterilized first.
I'll keep you all posted but I think (and hope) there won't be anything else to tell.
