> "Definitely"? A unit can look clean after treatment while still being mid-cycle. Rent it during that window and the roaches come back through no fault of the tenant.

"A unit" can, sure. But, "every apartment I've ever lived in"... come on! From TFA:

> I've noticed this myself with every apartment I've ever lived in. Things start off fine, but then mold starts growing in the bathroom, and a recurring leak springs up in the living room, and then roaches start appearing in the kitchen.

If this doesn't set off all the alarm bells, I don't know what does.

I'd extend some good faith to someone reporting a potential community health problem. And roaches in a kitchen isn't a smoking gun. Roach bait is food. Poisoned food, but food. You put it in the kitchen on purpose. Next to the food. That is how it works.
