Because my family share chronic allergies to toxic chemicals and other household threats, we choose to use Enzymatic ERADICATOR for Bed Bugs & Dust Mites during an alarming bed bug outbreak, after a recent business trip to up North. My wife continues to spray with less frequency now for weekly prevention. Before using Eradicator, I tried self-testing by spraying a some on my arm with no reaction. Eradicator has no objectionable chemical odor to any of us and seems to not affect anyones allergies in our home. Happily, there have been no new bed bug bites or blood spots on our sheets in the morning!
