Well I hate to knock you off the three legged horse you rode in on, but...
In a properly maintained rental unit the water heater should not be set at over 120 degrees to prevent scalding.
To maintain health department standards for cleaning linens that the renter will use (sheets, pillow cases, towels, hand towels, and wash clothes) the item must be laundered in no less than 180 degree water. Most local rental companies will use bleach in addition to this and I know several large scale operations even use an ozone system.
So your argument is still faulty in the fact that unless you are meeting these guidelines then the opportunity for germs, bugs, and other things to survive continues.
As to using duvet covers, unless it has an impenetrable layer such as plastic then it's not stopping bugs from taking up residence in the actual comforter.
I'm sure many owners and rental companies don't appreciate this thread right before what will be a very rough season.

Well, Well, now, now even you have gotten up on your high horse. I don't care to take a cold bath so you can believe that my hot water tank is turned up.
Oh as for you knocking me off of my three legged horse, you my friend are not even close. If this thread can make all of you figure something out then it served its purpose.
If you or anyone else feels the need to hate me for it then so be it. I'm sure you all will come up with a better solution to the current problem at hand. I'm not the one renting condo's out with comforters that are not been washed but once a year that is some of you.
I have only brought it out into the public eye. Once a month would be better than once a year wouldn't it. Question: Have you ever sat your bare aXX down on a comforter before. Now do you see its a little different than people sitting in a movie theater. Please
Address the problem at hand and stop trying to shot the messager. This is not about me its about you.
