I got a lot. thanks a million.
In fact, one of my kitchen wall is facing the parvis where unforturnately become a "rabbish hole" (no entrance to it,so can not be cleaned), that's why from time to time one or two of the cockroaches got lost and can be spotted, making me so sick and started to quesiton abt everything...also make me want to change the house
Generally, my kitchen is clean enough. but i got many useful information to make it better even.
