We bought Real Kill Indoor Fogger for Insects, with six cans in the box for $9 at Home Depot. Closed up the house. Placed 4 cans in the basement, and two cans upstairs. Vacated the house during process. Upon return, (the next day), there were spiders alive in several areas of the house, both upstairs and downstairs. Have since seen numerous (types) of spiders in all different places, including a spider making a web on son's pillow in basement bedroom one week later. It is a big ordeal to remove our pets and people out of house for this problem. It is a big disappointment when the product is worthless and you throw away time and money.
