Limitations, Restrictions, and Exceptions


FOR USE IN: Food and Non-Food Areas of Manufacturing, Industrial and Food Processing Plants. Non-food areas include boiler rooms, garbage rooms, drains (to sewers), entries and vestibules, machine rooms, garages, mop closets, and storage (after canning or bottling). Treating within food areas of food processing plants is limited to spot and/or crack and crevice treatments.

Treat where insects are found or normally occur. Application of a 0.25% solution is suitable for control of light pest infestations (i.e. maintenance

applications). Applications of a 0.5% solution provides residual control of heavy infestations (i.e. clean-out applications) and where extended residual control is desired. A period of 4-7 days is usually required to observe maximum effectiveness on insect populations. Do not re-apply more than once per every 7 days. Apply spray solution so that spray drift is minimized to avoid non-target surfaces. When using as a spot treatment, do not exceed 2 sq. ft. per individual spot.
