I have cockroaches problem in Kitchen in my apartment and the only opening to drainage there is obviously the kitchen sink but it doesn't look like they are coming from there (they are found on Kitchen floor).
But shouldn't an apartment be otherwise totally sealed to outside world or water? This is on 2nd floor. So where does these cockroaches lives, probably not in the drainage right in this case right?
The cabinets are fairly old and I suspect there are holes somewhere. I treated the apartment extensively couple of times but problem has not gone away.
So just to understand the problem, say if I redo all my cabinets, pull them off, make sure there are no holes in walls etc and put brand new cabinets, will this likely eliminate the cockroaches?
My theory is that the cockroaches could either live in drainage or outside drainage. I suspect the later is the case in my apartment. Shall such measures potentially eliminate the hidden living spaces in the kitchen?
From my experience at least, I have generally seen cockroaches in older houses perhaps for that reason. Has anyone had cockroaches problem in new constructions?
So could this be a valid motivation to redo the Kitchen as well which is kind of old?
