After the panik, I ordered several sticky pads to sample the cockroach. I did some examination around my kitchen and I don't think it's very habitable for them. My neighbors tend to put their garbage in the corridor, so that might be the issue.
Anyway, if I didn't see more cockroaches, then I should be good.
@trinsec by sampling I'm capturing and counting them. But now it's two weeks later (I went to shangrila for a week, so there is no food and water, the trap should be working), I only saw 1 cockroach, so I'm pretty sure it's an occasional invader. What a big relief 🙂
@skyblond@qoto.org 'to sample the cockroach'? What? You're going to taste-test them? 😂
I suspect you might mean capture?
If your kitchen is clean, usually there's not much to worry about. They can come from anywhere. But the 'I don't tihnk it's very habitable for them' isn't saying much. After all, if there would be a nuclear war and everybody is dead, the cockroaches would be the only one to survive. ;)
