HVAC and incoming stinkbugs (floor, roof, window, ceiling)

[tidaldream]

Every evening we get a stinkbug flying around on our second floor.
We catch it, flush it away..
Next night, same thing..

Last night, twice.

There are no lights on except for the TV glow.

I've had a suspicion for a long time they are either coming in through the ceiling fan in the bathroom
or the cool air vents in the floor (from HVAC)

Do you think either is at all possible, or not?

Anything is possible. They are amazing at being able to get into the house. Ugh! When I lived in Pennsylvania, every once in a while we would get them hanging onto the inside of the upstairs bedroom window screen. Never knew how they got in but I'm assuming there was just enough of a gap for them to crawl into.

Do you have screens on the vent on the roof for the bathroom ceiling fan?

The only consolation that I can give you is that you are ONLY seeing one or two a night. Some houses get absolutely infested. Just UGH!

So far *knockonwood* we haven't seen any down here in Florida.
