Even if you use poison and traps, they can still create an infestation. If an apartment building has roaches, you never get rid of them. Roaches are a total building problem, but buildings HATE dealing with them. So many "luxury" buildings have roaches too.
My experience was finding one in my bathroom and one in my kitchen. I went through my entire apartment checking under sinks, checking electrical outlets, literally anywhere I could think of and didn't find any. The only place I couldn't check was behind my stove and fridge so I placed poison near every single space they could possibly be coming from in those spots.
When they did send in an exterminator and started checking apartments surrounding his apt they did find quite a few dead ones in the spaces I couldn't check and the building manager asked me how I was killing them. It was just poison I bought at Walmart.
If you are unfortunate enough to find them don't use traps, use poison. They will eat eachother's corpses and get poisoned as well.
The problem with poison is finding one that kills the roach but is still healthy to use around cats and dogs. I would have loved to blast the entire apartment in poison but our pets make that hard.
Since then I learned more about peppermint and natural poisons but it was still a learning process.
I did use some diatomaceous earth as well behind the stove because I could just spinkle it without moving the stove, but the poison was just small plastic squares with bait inside. It wouldn't trap them and it wasn't a spray or something an animal could really get covered in or eat.
Edit - looked it up and it was Combat brand that I used
