Is this huge beehive?

Just found this on my house, bigger than basketball, what is it? Is there a public service to remove it or should I call private company? Thanks for your info!

I am near Cincinnati OH.

It looks like a paper wasp hive. I believe most all but the queen die once it freezes and she moves on to overwinter. You don't need a service. Remove the nest after you see no daytime activity. From my experience the nest is abandoned. A problem for us is the damage to outdoor wood furniture and cedar decking.

MaypopLaurel,

Thanks so much for your help!

thanks so much! So we will wait till freezing like Dec or Jan to do it.

Do you think there might be inside damage we will to check?

MaypopLaurel is correct; it most likely was made by bald-faced hornets. At this time of year, the nest likely already is empty and should be safe to remove. There shouldn't be any damage inside the building, but the nest residue may take considerable elbow grease to remove from the exterior.

We have a cottage in N. Ga, with an ill fitting screen door into the vestibule. Several years ago, while we were away for a month, this nest happened. We had to wait until nighttime and spray. There was a steady stream coming and going under the door. When I went to remove the nest I discovered the wasps had chewed through the sheetrock and a bit of the rafter. Well, since there was already a collection of rocks, animal skeletons and shells gathered from walks in our woods, I left it as a decorative feature. Saved me doing a sheet rock repair but I do have to dust it now and then. :)

Thanks to everyone's help!

Can we just take it down by a stick or do I need to climb up there to clean it up well so they do not come back? It is huge, scary...

They do not return to the same nest.
A new queen may come to the same area and start a new nest. If the area was a good one the first time, another queen may think the same.

If you can get up there with a ladder and a scraper of any sort you can do a better job of removing it. A clean scrape against the house, rafters and wall, then assess possible materials damage.

I have removed yellow jacket nests. They are similar, with similar life style.
Makes a nice 'show and tell' for school.

Paper wasps, including bald-faced hornets, do not re-use old nests. You are going to need more than just a stick to take it down; be prepared to scrape, and then deal with the residue. I'll try to attach an image of what remains on a structure after nest removal.
