Need to keep bees out of furnace air intake pipe

Hi, I've had a problem with bees getting in the PVC air intake pipe (or whatever the proper term is) for my furnace. They make nests wherever they can! I was thinking I could put a screen of some type over both the intake and outake. Has anybody done this? Is there something made specifically for this? I think the PVC is 3" or 4". I'm not sure if this will be a problem--I don't want to restrict the air flow significantly.

Thanks for any ideas.

There is nothing you can put over the end of the pipe which will keep out the bees & still allow the proper air flow. I have one customer who caps his pipes in the spring & removes the caps in the fall.

Red face Keeping out insects from air intake and exhaust pipes

Purchase small cheap nerf balls and wedge them into the ends of the PVC pipe for the summer months and pull them out for winter heating. works good for me ao far.
