Hei!
 
In my case (I'm non-commercial), yes, I always close the entrances, but
am very careful with ventilation and damp down the flatbed under the
hives in dry hot weather.
 
BUT...Steel Wool?????
 
Sounds awful! What is wrong with a strip of foam rubber pushed into
the entrance (using every Norwegian workmans best friend -- his
universal, do everything knife! I guess the sharp end of a hive tool
would work just as well.)
