Thanks for the input everyone!

I'm kinda leery about using the fans as I want the concentration of dichlorvos to max out in the room. My whole house isn't much bigger than 1300SF, and that's the area that the NPS treats I believe. So, I'd rather keep this stuff confined to the area it's needed.

The room generally runs on the cold side... and I have a direct vent to the small garage which is freezing. I think I'll just run the lamp at 24"-36" and crack that vent to let in some cool air. That room is really small so it shouldn't dilute the concentration too much.
