I would not recommend to spray Bifen or any insecticide around an Asthma patient. If you leave the structure or building and then let someone treat for you, make sure everything is dry and all odors have dissipated. This takes 3-4 hours in most cases. Bifen IT does not have much of an odor, but I always like to stay on the safe side of my recommendations.
