I just can't imagine spraying that stuff inside the house. Especially in the winter when we can't open any doors or windows. I'm very sensitive to chemical smells and dh is too, and I have one dd that has had asthma episodes in the past (it's been a while though) so I don't think I'd be comfortable using it. And I don't have a big clean area outside to lay out a quilt (our driveway is very rough gravel).
