Hi folks, so I recently found a cockroach in my home, just one, no others since. However I'm certain that I'm going to see more, and it feels like there is very little I can do about it. I have a phobia of insects, and I live in China, and nobody in China seems to care about cockroaches. So they are in the building I live in, which means that I'm probably going to see more in my home at some point in the future. I actually can't sleep thinking about it, because I keep imagining the disgusting things crawling on my bed while I'm sleeping. I can handle some insects, like most nights I get moths in my house and I don't care about them, and if I see a spider while scared, once it's been killed and disposed of I feel safe knowing that I'm not infested with them. But cockroaches give me a whole new level of terror, simply because I know that if you do get infested (likely since the building is probably infested) then you will start seeing hoards of the horrible things everywhere, and I really can't stand that. My landlords advice "clean up". What can I do?
