Short answer: wasp spray is made for that, but any time you go after a nest you need to make peace with the fact you might get stung.

How high up is it? Looks like bald faced hornets, which wasp spray is exceedingly good at making dead fast, but if you're talking ladder needed it still may be questionable. Also keep in mind whatever the max range is quoted on the spray doesn't mean vertically (e.g., Raid will get not spray 15 feet straight in the air).

Anecdotally, we had a wasp nest at the junction between our garage and house roofs. From the ladder with my arm at full reach, the stream of the spray fell about 1 foot short of the actual nest. When I got on the roof to finish the job, they were hosed up enough from being near the fumes that they were unable to fly and dying.

If it is within spray reach, if possible wait until after dark to spray it. During the day there are hornets coming and going foraging, so you'll get the most bang for your buck hitting them at night.

Quick e: also long sleeves and gloves never hurt. If you don't already have the spray, they probably sell mosquito head nets at wherever you buy it, if you want to feel extra secure.
