We would recommend using Invade Bio Zap for the variety of things you would like to do. It is labeled to be used on soil, gravel, crawl spaces, concrete basements and garages or insulation in attics, fabrics, carpets, walls, garbage receptacles, and restrooms. It does contain the same active ingredient as Invade Bio Drain, however, the makeup is different which means it will work differently if you use it in places it is not labeled for.
The product can be used to clean behind the laundry machines, but it will not reduce lint.
InVade Bio Zap can be used in a ULV fogger to fog crawlspaces only. If diluted it would be with water only at 1 to 2 parts water for spraying.
InVade Bio Zap would not effect building structures when applied to wood/walls to remove stains and eliminates organic odors.
You could potentially apply an Insect Growth Regulator (IGR) after an application of InVade Bio Zap has dried completely. Be sure that the IGR is labeled to be used in the area you want to treat.
InVade Bio Zap is a specially formulated cleaner that helps remove stains and eliminates organic odors without harsh chemicals or fumes. It is not labeled/designed to dissolve feces.
