Roaches and I’m pregnant 😭

Hello. I’m almost 26 weeks and living in a rental home with my fiancé who’s paying for it. We got this place a little over a month ago, and the previous tenants left behind a ton of trash which caused a tonnnn of roaches (I believe mostly German). Landlord sprayed the house himself twice which I can admit killed most of them but there’s still stragglers. My fiancé hired actual professionals to come out and spray. They sprayed once a couple weeks ago and I think they’re coming again. It’s like for a few days I see none and think they’re gone then the next few days I see a few and im so fed up with getting my hopes up. Im scared that they will never go away. I have a place to stay with my mom who’s 2 hours away and I don’t wanna move away from my fiancé but I don’t want our child growing up having to live through that and having to constantly worry if a bug is gonna crawl in her ear or in her stuff. Any advice on what I should do? Im just so frustrated and fed up with having to deal with something we didn’t even cause to begin with. If I don’t feel 100% comfortable here than how am I gonna feel even remotely comfortable with our child here? I’m so greatly appreciative of my fiancé and him providing for me but I just can’t with the bugs.
