You can try this.
You'll need a partner, a bucket of ice water, and a hand sprayer with ice water in it. You'll also need a razor blade (like box cutter) and some Super Glue.
One person mans the bucket and the sprayer. The other mans the knife and super glue.
1. Toss the bucket of ice water on the nest while it is covered with wasps. You might practice this bucket tossing on another object to be sure you can do it well before goofing it up on a live wasp nest. Once the ice water hits them, all the wasps will fall to the ground. Use the sprayer if icy water to keep them cool. As long as they are cool they will be immobile.
2. Carefully (and quickly) scrape the nest off the house at the attachment point. Then glue it back up somewhere close by but where the wasps won't bother you. You might not want to stick around when the wasps warm back up.
Wasps are not aggressive unless they feel their nest is threatened. A nest on a slide is guaranteed trouble. Wasps nesting up in the rafters can easily be left alone. Learn not to swat at them. I had a wasp bump into my face and land on my glasses last week. I have been dealing with wasps on a mutual friendship basis for years so I left it alone to explore. Just as suddenly it jumped off my face and went back to the nest. That nest was there last year but was not big enough to be disturbed by my screen door. Now it is heavy with eggs and hanging down low. My back door is now off limits until I get around to moving the nest. Here is a picture of that nest. You can see where the door opening just barely touches the bottom of the nest. That is enough to send them all abuzz. If that happens, your best strategy is to close your eyes and stand perfectly still. If you feel one touching you, continue stand perfectly still. At the worst you will get stung once. If you start swatting you'll get several stings.
Wasps really are social critters. Once they learn your routine and learn that you are not a threat, they will leave you alone...as evidenced by how close I was able to get to take that picture and not have a single one jump off the nest.
