Baby coaches and roaches in my kitchen?

I live an apartment. I keep everything clean . But i been noticing little cockraoches not big ones actually but small ones and those smalls ones lay eggs and make smaller ones idk .. i think they are under my refrigetaor making babies or something.. i havent bought anything to kill them because they are under ny fridge. I notice they come out at night when its dark!!!! They dont like us they run fast. But now im scared and grossed out idk what to do??? Buy a repllent ? Or call my manager???? Or both? They are making babies and babies idk where they are coming from. Vents? Cracks? I do have in my pantry an attic where they come and fix stuff but ite closed kinda.. i hate bugs and get uncomfortbale becayse i have to sleep with them knowing they are in my kitchen and shit
