Onslaught FastCap Spider and Scorpion Insecticide

Bed Bug Supply Review - see what our experts have to say about this product
MGK has enhanced Onslaught’s fast-acting and long-lasting residual strength, for greater efficiency against a slightly narrower range of pests. They started with Onslaught’s active ingredient, esfenvalerate, a proven residual pyrethroid. Then, they added prallethrin for better control of flying insects, and mixed the two with Exponent for faster action and less resistance. The result is Onslaught FastCap, the residual of choice against spiders, scorpions, and more. It kills faster, lasts longer, and is more economical to use than its predecessor.
Similar to Onslaught, Onslaught FastCap has one of the most flexible labels in the industry. It is effective against over 170 insect species, and is labeled for food and non-food areas. Onslaught FastCap can be used as a broadcast or crack and crevice treatment, a perimeter spray, wall void injection, or in a tank mix. It can be sprayed on any surface that won’t be stained by water - to be sure, test the surface by spraying a small amount in an inconspicuous area.
To control bed bugs, we recommend using Onslaught FastCap as a spot treatment on places where bed bugs are likely to hide and travel. This includes headboards, floorboards, and where the walls meet the baseboard. Focus your spray on cracks and crevices to ensure that they get filled with the mixture.
Product Information
Onslaught Fastcap is a microencapsulated residual insecticide. What that means is that the chemicals are encapsulated, and slowly release over time. That slow release allows for an incredibly effective residual protection. Onslaught Fastcap's flexible label allows for use against a broad range of tough pests, like bed bugs, roaches, scorpions, spiters, and more.
For use against bed bugs, start by thoroughly cleaning and sanitizing the mattress and box spring, and treating them first with a contact killer. Then, apply Onslaught Fastcap as a spot treatment to cracks and crevices around baseboards, floorboards, headboards, and wall voids.
Treating for mosquitoes / Zika virus prevention:
Onslaught Fastcap is quickly becoming the premier option for mosquito control to help combat the current Zika epidemic. Pest control operators that are experienced in mosquito elimination and prevention recommend using NyGuard IGR in a tank mix with Onslaught Fastcap. NyGuard mimics juvenile hormones to effectively break the reproductive cycle of mosquitoes and other pests.
To combine NyGuard and Onslaught Fastcap in a pump sprayer, mix 4 mL of NyGuard with 4 mL of Onslaught Fastcap per 1 gallon of water. This will give you a combination of knockdown, residual kill, and residual growth regulation for up to 1,000 square feet of treated space.
