Cockroaches can and do sometimes crawl on you at night and may even crawl in your ear.
Also cockroaches like to go around during the night, which coincidentally is when people sleep.

Cockroaches also like small, warm, humid places.
The problem is that once the roach crawls inside the ear, it's likely to get stuck.
Cockroaches do die in freezing temperatures.
Cockroaches can only survive temperatures above 15 F degrees before they die after being exposed to the 15 F or 0 F degrees for a prolonged period of time.

The house got cockroaches and the renters moved out.
