I opened my door at night, and a bunch of gnats and moths flew in. I sucked them up with the hose attachment to my vacuum cleaner, but I’m afraid if I put my vacuum cleaner back in the broom closet, then all the bugs will fly back out. I’m thinking surely there is some sort of flap or valve to prevent this, but I don’t know for sure.

Yes, they will. The vacuum doesn’t kill them. I tried this when we had the asian lady beetle infestation, and the little buggers were crawling back out of the hose! Try spraying first them get them with the vacuum. 🙂
Surely not
Yes they will fly out some of them, not all. The best thing to do is kill them and put them in the toilet and flush
It probably depends on what kind of vacuum you have and what kind of filter it uses. But it’s extremely likely that, like you said, the bags that collect all the junk have a flap on it that keep things from coming back out. I use my vacuum to suck up spiders all the time and never think twice about them coming back out!
I doubt it but that is a funny thing I have wondered about spiders before too.
I am a pest controller, the best way to eliminate bugs of any kind from exiting a vacuum bag is to whilst the machine is still sucking spray some insect spray into the vacuum hose for 1 minute. It kills all the bugs in the vacuum bag and also in the vacuum hose.
