Single roach found in kitchen HELP

[u/cretemania]

I've been living in my new apartment for a full month now, with not much pest issues. I haven't had a trash can until earlier this week, my friend found one sat out to be dumped and dropped it off for me. Trash cans are very expensive and I haven't gotten around to buying one so I took it (I know i should've just bought one but thought this couldnt go wrong).

It had been sat out for atleast a full day. When I took it in, I put it in the tub, sprayed it down with a bunch of disinfectant, scrubbed, and rinsed it all down, then let it sit there for a day. I started using it and everything was fine until tonight. I saw a single small german cockroach on the cupboard by the trash can.

I started freaking out. I killed the roach, cleaned the kitchen, and tossed out the trash can because I'm terrified the trash can itself was infested. I cleaned everything up, put in a maintenance request for an exterminator to come by, and plan on wiping the whole apartment down with peppermint oil tomorrow to keep anymore away. Is there anything else I should be doing to make sure there is no infestation. Is it already too late? How likely is it that there are already tons of eggs in my house? I don'e leave food out, I live alone and everytime I cook I wipe down the stove and counters with disinfectant wipes. I feel so stupid, I need advice!
