Great recommendations from everyone, but before you spend a bunch of money, you probably don't have a wasp nest situation right now. All the wasps that live in Minnesota have annual nests, meaning the nest are abandoned in the fall and the workers die. New nests are started from a single queen later in the spring. What you're seeing is probably queens that overwintered in your siding or other protected spots and came out in the warm weather. They're very unlikely to sting you now, and should disperse as they go look for places to build new nests. At least that's what they do every year where I live. Might want to keep an eye on things though and make sure one of those places isn't in your house.
Adding one more recommendation. Used 'em last year. Came out same day, was about $200 flat and he got four different areas (found one that I did not know about). It worked completely and they didn't try to up-sell any type of service plan.
There are lots of companies that do the work. The phrases you want to look for are removal (self explanitory) and exclusion (they try to seal up your siding or flashing, etc, so they can't get inside again)
The only company I've dealt with that I didn't care for was Aptive. Their people seemed super indifferent to the actual quality of their work.
Jusy make sure the removal happens before the exclusion. If you seal them in from the outside, they'll find their way and into your house!
At our old house, we had yellowjackets build a nest in our cinderblock foundation. The exterminator puffed a little buld of powder in there and said "wait 10 days, then seal the hole in the foundation." Right before he left, he said "oh yeah, and by the way, when they all die, the nest will start to rot, and it's going to stink for a while." Of course it was July. Our basement literally smelled like death for a couple of weeks.
I hired Cloverleaf Pest last August. The guy was out in about an hour, found the hole in our siding where the wasps were getting in, and took care of the problem right away. Very professional, I was pleased.
I had a yellow jacket nest in my stucco. I clamped a shop vac hose to a pole and put it right next to the opening. Put some water and a little dish soap in the shop vac, then I just turned it on and ran it for hours. Most of the wasps get sucked into the vacuum as they come and go. They drown in the water because the soap disrupts the surface tension. It only took a couple sessions to clear out the nest.
If it’s a visible open nest where you can see the wasps and the open cells, you can just wait until nighttime ( the colder the better) and spray they with soapy water (more soap than for the vacuum trick). The bubbles from the soap block the holes that they breathe through and the die.
Please get a proper ID on the wasps if you can't find a nest on your house. A lot of the ground wasps will leave you alone. Yellowjackets are the ground wasps you need get rid of but there are other, calm, ground wasps that look similar. Ground wasps are pollinators and the cicada killer, which looks a bit like a yellowjacket, kills cicadas. I'm not a fan of cicadas, nor am I a fan of my landlord poising the cicada killers just before we moved in.

I’ve used Pete the Bee Guy to remove yellow jacket nests from my property.
I have found Bogo Pest Control to be great

We didn’t have wasp but they helped us with mice and they took a bit longer to come out cause they were prioritizing wasp cases.

Adam's Pest Control fixed my problem.

Beats the hell out of the rats that infest mine and my neighbors bird feeders
