Not to be a thread thief but I also use screening for my inside floor vents for various dirt prevention especially sweeping over the floor vents, lots of dirt and other things don't fall in, especially my keys (lol) if you know what I mean.

This is correct. I also found them in my engine's air cleaner. If you have the V10 and remove the air cleaner housing, you will see two holes in the bottom (to drain any water?). They, the wasps (mud daubers), wormed their way in and made themselves a cozy little home. After doing the wasp battle to get rid of them, I covered that and my fridge vent as well. And don't forget the water heater vent.
If you go to those lengths you probably should cover the fridge vent on the roof too.
You can and should have a screen over the furnace, water heater and fridge exhausts.
The idea that the exhaust has to breathe and comparing it to the exhaust system of an internal combustion engine is a joke. Just place your hand over it when any of the appliances mentioned are running...….the pressure (if you can call it that) and volume is negligible.
Hi all. I put a bug screen over my furnace vents and exhaust. I thought I heard at one time that it is not a good idea to have a screen on the exhaust. Just looking to get some feedback on this subject. Has anyone also done this? Has anyone come across any problems by doing this?
We have had a "bug" screen on units for the last 20 years with no issues. The wasps in NC like to build clay tube nests all over the place including the ref ridge vents. These work great and eliminate a lot of problems. Just make sure to use the full screen type, not ones with a solid cover surrounded by some screen.

I'm sure this doesn't make any difference but the steel wool is flammable. If you tie it on a wire, lite it and swing it in a circle it makes a cool photography effect. That's the only reason I know it's flammable.
My husband and I drove about 90 miles to camp for the weekend (In Sept) and I saw a wasp fly out from under the hood. After opening the hood we found two wasp nests and a ton of wasps. It took a while to get them out. My husband just put in a fresh can of wasp spray before we left. No stings but it was scary.
