Onslaught Fast-Cap Spider & Scorpion 16 oz Insecticide - Long-Lasting

In this review of Onslaught Fast-Cap Spider & Scorpion 16 oz insecticide the bottom line is simple: this is a practical option for homeowners and pest control enthusiasts who need fast knockdown plus residual control against scorpions, spiders, and other labeled insects. It stands out because it combines quick action with a lasting residual effect while being formulated for both indoor and outdoor use. The package also includes protective gloves, which is a useful touch for straightforward, safe application around the house or yard.

Key Features

• Quick knockdown: The formula delivers fast-acting control so pests often stop moving seconds after direct application, reducing immediate risk and visible activity.
• Residual control: Treated surfaces retain effectiveness over time, helping prevent reinfestation of spiders, scorpions, and other labeled insects.
• Broad spectrum: The product targets a wide range of pests listed on the label, making it useful for mixed infestations rather than a single pest type.
• Indoor and outdoor use: The insecticide is suitable for application in both indoor living areas and outdoor perimeter zones when used according to label directions.
• User-friendly packaging: The 16 oz size and included USA Supply protective gloves make initial application straightforward and economical for typical home jobs.

Who It's For

Homeowners dealing with scorpions, spiders, or mixed household pests who want both immediate knockdown and ongoing residual protection will find this product useful. It is especially helpful for people who need a single, versatile product to treat both indoor corners and outdoor entry points without switching formulations.

Professionals who require specialized or concentrated formulations may prefer trade-only concentrates or larger-volume products, and anyone unwilling to follow label directions for indoor use should look for alternative non-chemical control methods.
