Onslaught FastCap Spider & Scorpion Insecticide combines fast kill (action) and long residual activity against pests listed on this label when applied as surface or spot treatments, injected into wall voids, or as a crack and crevice spray in and around residential and commercial structures, as well as on turf and landscaping. Onslaught FastCap Spider & Scorpion Insecticide may be sprayed on any surface that will not be stained by water. DO NOT use this as a fogger or apply it as a space spray. Injector application equipment that delivers low volume treatments may be used to make crack and crevice injections or spot and general surface treatments.

Spiders, scorpions and other listed crawling insects Indoors:

Apply as a course, wet spray to surfaces where these pests are normally found. Treat floors, baseboards, around doors and windows, in attics, crawl spaces, eaves, corners, closets, walls, utility pipes, storage areas, and all cracks and crevices. Treat underneath sinks, dishwashers, refrigerators, stoves, the underside of shelves, drawers, cabinets, areas behind pipes, and in all places where these insects shelter. Contact as many insects as possible with direct spray. Repeat applications as needed, but do not exceed more than one (1) application every seven (7) days.

Mixing tip. Shake Onslaught FastCap bottle well prior to mixing. Clean spray equipment before using or diluting Onslaught FastCap. For dilution, add half the required water to spray tank, then add the appropriate amount of Onslaught FastCap. Agitate the mixture, and then slowly add the remainder of the water. Agitate the spray thoroughly before using and also occasionally during use to ensure dispersion. If you use a spray filter screen, they should be 50 mesh or larger.

Use Onslaught FastCap as part of an IPM program. Tank mix Onslaught FastCap with an IGR such as NyGuard IGR Concentrate to break the insect growth cycle and control future emerging insect populations. Do not apply Onslaught FastCap as a fog or space spray. Fog first with a product such as Riptide Water-Based Pyrethrin ULV to get the quick knockdown action of the fog followed by a surface application of Onslaught FastCap for residual control.
