Actually, I've become quite good at hitting insects with rubber bands shot from my fingers. I just happened to be spraying contact cleaner that day and used what I had. If I had rubber bands near me that day, he would likely have been just as dead.
For photography, I keep Atmosphere spray in stock. I also have a fogger and fog juice, both the regular and fast dissipating versions. The regular is too much for my small studio and takes an hour to be completely gone from the air. The quick dissipating is a bit too quick, so I frequently blend the two. I've become quite proficient at getting the rate of dissipation down to a workable level. I think my fogger is a bit over sized for the studio and this doesn't help matters either. It's a 900 watt. A few seconds burst with my blended fog juice is all that I usually need for about 5 minutes of shooting. If longer shooting is required, another short burst may be necessary.
