Landlord chose and paid for this. This would not have been my first choice (I was thinking nuclear chemicals, not enzymes). The enzyme treatment works. Before and after glue traps show no evidence of bugs whatsoever. Additionally, I've desperately searched all the places I'd expect to find a living or dead bug, nothing. I was prepared for a huge impact on the home (tenting, moving and disposing of things, etc). None of that, so that's a huge bonus. Only impact was coming home after work and finding my bedding stripped off and bagged unusable for the night. I had to sleep without a pillow or blankets until doing laundry the next day. 10/10 recommend.
