Wasps and lots of other insects love ivy flowers as they are a great source of nectar and / or pollen late in the season.
There is no problem with this - they just congregate on the flowers in October/ November, stocking up on food - it's like the first day of the sales and they won't be interested in you.
What would the hive be for? Honey bees might use one - if you were to put a queen in one. Wasps just wouldn't be interested.

Beattie's right - wasps don't live in hives, they build their own nests, usually in your loft or similar. As for their liking ivy, ivy has to be pretty mature before it flowers anyway, and I've certainly not noticed crowds of wasps hanging around ivy - well, not unless they're hornets, the ivy is huge and mature and they've got a nest in it.

We used to have a high wall covered in a draping of mature ivy. It was in the sun and used to be ABSOLUTELY SWARMING with all flying insects in October/ November when the ivy flowered. As you walked by, the bees, wasps and everything else would all rise up buzzing and humming, and settle again as you passed.
It was scary unless you knew what it was - but as I say, they were all intent on getting as much food as possible and posed no threat at all.

It was fascinating to watch them prodding the flat flowers with their tongues, sucking up the nectar.

Well you're right Beattie, of course, all insects love ivy flowers, but often, ivy doesn't flower because the owners keep it clipped back - in which case, insects hovering over it shouldn't be an issue.
