MGK Onslaught FastCap insecticide 32 fl oz — long‑lasting residual control for spiders & scorpions

MGK Onslaught FastCap is a controlled‑release insecticide formulated to deliver extended residual control of spiders, scorpions and a wide range of other crawling and flying pests in and around structures and landscapes.

Designed for professional and agricultural use, Onslaught FastCap uses encapsulated active ingredients that gradually release to maintain efficacy over time. It can be applied to turf, ornamental beds, livestock facilities and some indoor broadcast scenarios, providing flexible options for perimeter defense and targeted treatments. The product is sold in a 32 fl oz container and is intended to be mixed and applied according to label directions for safety and optimal performance.

How does Onslaught FastCap work differently from typical spray insecticides?

Unlike fast‑acting contact sprays that lose potency quickly, Onslaught FastCap relies on controlled‑release capsules that emit active ingredient slowly. This creates a longer residual surface presence, reducing the need for very frequent reapplications while still affecting insects that cross treated areas.

• Encapsulated formulation for gradual active release over days or weeks.
• Effective as a residual barrier on structural perimeters and landscapes.
• Reduced immediate degradation from sunlight and environmental factors.
• Compatible with typical dilution and application equipment when used per label.

Where can I safely apply MGK Onslaught FastCap?

Onslaught FastCap is labeled for use in a variety of settings including turf, ornamentals, landscapes and livestock facilities. There are also approved indoor broadcast uses—always consult the product label to ensure the specific site and target pest are covered and to follow any required precautions for indoor applications.

• Perimeter treatments around homes and commercial buildings.
• Ornamental beds and turf areas for landscape protection.
• Livestock buildings and related outdoor areas where pests may congregate.
• Certain indoor broadcast uses when applied according to label instructions.

What pests does this product control, and how broad is its spectrum?

Onslaught FastCap targets spiders and scorpions specifically and also controls a broad spectrum of other insects commonly encountered in and around structures and landscapes. The label lists susceptible pests and recommended rates, so consult it for details on specific target species and application rates.

• Primary targets include spiders and scorpions for residual barrier control.
• Also labeled for many crawling and flying insect pests in agricultural and structural settings.
• Use label guidance to match dilution and application method to the pest and environment.
• Works best as part of an integrated pest management plan.

How should I apply and store Onslaught FastCap to ensure safety and performance?

Always follow the product label for mixing rates, personal protective equipment, and application equipment. Apply as a uniform spray to target surfaces and avoid unnecessary contact with non‑target areas. Store the product in its original container, tightly closed, away from heat, children and animals.

• Mix according to label recommendations for the target pest and site.
• Wear appropriate PPE such as gloves and eye protection during mixing and application.
• Avoid application during windy conditions to minimize drift to non‑target areas.
• Store in a cool, dry place in the original labeled container, out of reach of children.
