[Avodah] Sukka must be kosher for sleeping?

[Moshe Y. Gluck]

R' Ben Waxman:
Someone told me that he heard a "svara shiyur" in which the rav said that it
could be that if a sukka is not suitable for sleeping in, then it isn't
kosher for eating in. For example, if a sukka is mosquito infected and you
can't sleep in it, then you shouldn't eat in it.
 
Anyone hear anything like this halacha l'ma'aseh?
---------------

See Shulchan Aruch Siman 640, Se'if 4 and the Ramah there, as well as the
Mishneh Berurah there, Se'if Katan 18 and Shaar HaTziyun Se'if Katan 22. It
seems that if it is impossible to build your Sukkah without mosquitoes then
it will be Kosher for eating, even though there are mosquitoes there and you
can't sleep there; if you could have built it in a non-mosquito infested
area and you chose not to, then the Sukkah is not Kosher.
