Anything in a spray bottles usually presents a challenge. My "studio" consists of a 1.5m square corner of the family room so as you can imagine space is at a premium. And having to go outside and up the end of the backyard to spray is a pain in the bum, plus it's usually windy and if I have washing on the line the drift can end up on my freshly washed white sheets. Now that would be annoying. So I devised my own little spray booth that fits neatly on my desk and folds up flat so I can slot it between other stuff that's shoved under my desk.I cut up a cardboard packing box. Took out the top and bottom and one side.
