I used the Biocide Labs Spray and Bomb Foggers last year in my Mother’s fully furnished 1500 Sq Ft basement. Her dehumidifier had failed and mildew had bloomed on several walls. In 2 days her downstairs sewing room and bedrooms were like new and smelled wonderful. Twelve months later the rooms are still mildew free and she keeps the dehumidifiers going. I again used the same 2 products on a home in Atlanta that was empty waiting to be sold, and the summer rains had caused white mildew to appear on cabinets and door/ window frames. Again, the results are amazing. I also used the new ceiling whitener product on some brown atmosphere stains. It worked very well and saved us from painting the ceilings. Now we can safely and confidently sell this home. Be careful when letting off the bombs to keep your face away from the top of the bomb. I had a mask and protective goggles and clothes on. It goes off for several minutes, so I actually directed it toward the far away corners and then set it down as directed. I LOVE THESE PRODUCTS.
