CATALYST mixes easily with water and may be applied with most sprayers. Diluted spray mixture may be stored overnight and used the following day, but mixture should be agitated well prior to application to prevent the uneven distribution of product. Do not apply as a space spray. This product shall only be used for crack and crevice treatment. Crack and crevice treatment is application of small amounts of pesticides into crack and crevices in which pests hide or through which they may enter a building. Openings of this type commonly occur at expansion joints, between different elements of construction, and between equipment and floors. Apply as a 0.5% ai solution to crack and crevice sites only, where pests occur, including areas behind loose baseboards and tile, pipe chase penetrations, cracks in caulking surrounding doors and windows, under refrigerators, behind cabinets, sinks, and stoves, and cracks leading to wall voids. Areas that may have cracks or crevices that harbor pests include: storage areas, closets, under cabinets, and restrooms. Cover all foodstuffs in area to be treated or remove food prior to application
CATALYST in recommended dilutions is non-staining and does not cause damage to fabrics, plastics, paints, or other surfaces which cannot be damaged by water alone. Do not apply where electrical short circuits might result. Do not enter or allow others to enter until sprays have dried. Do not apply product in a way that will contact workers, other persons, or animals, either directly or through drift. Only protected handlers may be in the area during application. This product may not be reapplied more than once every 7 days and treatment may not exceed 2 applications in a 30 day period.

If no such instructions for washables exist, use detergent and hot water. Keep and wash PPE separately from other laundry
For crack and crevice treatments: NOTE: Following treatment, thorough ventilation of treated areas, by occupant before re-entry, may reduce potential odors. In buildings with restricted air flow, such as office buildings, ventilation is enhanced by adjusting ventilation systems to include outside air for 24 hours.
Food Service Establishments: Application is limited to crack and crevice treatments in food service establishments such as restaurants, cafeterias, taverns, delicatessens, mess halls, institutional dining areas, mobile canteens, around vending machines, groceries and markets where there is no contact with food and food service areas only in schools, hospitals, day-cares, and nursing homes; as well as non-food areas of eating establishments where there is no contact with food, and where no food processing, packing, and no food and/or feed warehousing occurs.
