PVC Intake/Exhaust for Furnace

We have a new 90%+ efficiency furnace with the PVC intake/exhaust pipes on the outside of the house.

I have worries about the open end of the PVC piping (we have bees that tend to build nests around our house, and I caught my 2-year old trying to throw a rock down the pipe). I was considering adding a piece of screen over the open end to avoid such problems.

Is it common/OK for people to do this? Is there a recommended material?

Thanks in advance for your help!
Paul

The inserts for downspouts work great.
Bulb shaped with the long prongs to hold
in the opening.

I wouldn't suggest a screen on the intake if your area has a foggy late winter season.. The fog tends to freeze on to the screen, and close up, and shutting the furnace down.. I've pulled a few too many here in Minnesota.
