Hello. I live in Scandinavia and am 15 years old. I haven't been in my room for a couple days or so, but today when I was in my room I saw a cockroach flying around. I smashed it and then leaved the room, and tomorrow I will clean the room (since it have been a couple months since I last vacuumed it, even through I don't find the room very dirty).
is there anything else I should do? Do cockroaches come in packs, or was there only this one? Any miracle-products I should try out? Thanks.
