Hello friends
I keep my kitchen clean,before going to sleep i clean all the places .
For the past e0ne year i have tried pest control by our apartment people,brought cockroach baits,used Mortein non fragrant pesticide....
But nothing seems to work. I don't know from which part they are comming...makes me really crazy. They come when i put of the lights. If happen to see my kitchen in the middle of the night ,i become really crazy

Don't know how to get rid of them. Please help me.....

Thank you friends in advance. Waiting for ur valuable suggestions!!
