I don’t know what kind of roaches you have or how many other units your place shares walls with but German roaches (the small brown ones) are hella hard to get rid of. Like typical treatment in a house, that doesn’t share walls with other people, takes 6 weeks. When you share walls with people, every unit you share a wall with should be inspected because other units could be the cause. German roaches are attracted initially to uncleanliness. Adults lay 4-8 eggs in their lifetime; eggs can produce 30-48 roaches, and they become adults without 1 1/2 months to 3 months. This is why German roaches quickly become an infestation.

I am a property manager in Texas so I’m familiar. German roaches also led to some intrusive thoughts and diagnosed OCD. I take these seriously and they can 100% cause inhabitability issues. They can also contaminate your food and carry bacterial diseases.
