When the recent cold wave hit, we had 2 wasps in the bathrooms, so did my neighbor. He mentioned he noticed a nest INSIDE the vent in the sofit. It appears the screen that is installed is fairly course and allows wasps to get inside, and then into the house.
Our solution:
Remove the outside vent cover, install some regular window screen and replace the outside cover. The much finer window screen will prevent wasps and probably most other insects from getting inside. It took me about 15 minutes to do all 3 vents in our house.
It appears there may be a variety of covers, so you may need to get new covers, or you may be lucky like me and be able to just remove 2 screws to get the cover off, install the new screen, and screw the cover back on.

Do you employ a pest control company? We use Florida Pest Control, whose technical knowhow and reliability is excellent (if their office service is somewhat on the sloppy side...). According to our contract with them they will take care of things like that: included in the price. Last year I noticed that I had a lot of winged company while mowing my lawn; turned out there was a rather large wasp nest in my hedge. A call to Florida Pest Control and a tech who arrived less than hour after the call took care of the problem.

I had the same problem and solved it the same way.

The pest company will take care of the wasps, but will not replace the screen to stop future intrusions (which is what this post was about).

Great idea, thanks !

The only issue with this solution is that the vents also suck enough dust particles into the duct that it can build up on the finer screens and effect the air flow...so it will be necessary to check it occasionally for blockage.
