For the past couple of months I have had a swarm of about 100 very small
flies at the corner of my garage. The swarm seems to stay in one position.
About 4 to 5 feet from the ground and about 1 foot from the wall. The corner
faces north and east. I have repeatedly sprayed them with a fly killer but
as soon as the spray disperses they are back again.

You'll only get rid of them with fly killer if you can stop new ones
coming to take their place.

The only thing growing in the vicinity of the swarm is an Ivy. This is about
3 feet away but the flies do not seem to go near to it.

Can someone please advise me what would cause this and how can I get rid of
them.

It's probably an area of still air.
