How Onslaught FastCap Insecticide Works

Onslaught FastCap Brown Recluse Spider and Scorpion Insecticide contains two primary pyrethroids: prallethrin and esfenvalerate. These pyrethroids disrupt an insect's nervous system, weakening it significantly and causing death. Onslaught also contains an effective synergist known as piperonyl butoxide, which enhances the pyrethroids and makes them even more potent. This fast-acting insecticide quickly knocks down the target pests and provides residual control when it's applied as an indoor broadcast treatment or an outdoor spray.


Where to Use Onslaught FastCap Brown Recluse Spider and Scorpion Insecticide

Onslaught FastCap brown recluse spider and scorpion insecticide is labeled for commercial and residential use both indoors and outdoors. It keeps pest infestations from taking over garages and attics and prevents unwanted nests and webbing in office buildings, hotels and restaurants. Use it to treat the pests' hiding areas such as beneath appliances, around plumbing pipes and inside cabinets. It can be used in conjunction with an integrated pest management program alongside pyrethrin-based foggers. However, never apply Onslaught as a fog or a space spray in the target areas.

Onslaught FastCap Insecticide may be labeled as a spider and scorpion insecticide, but it targets more than these two pests. In fact, it works on numerous crawling and flying insects inside homes and businesses and outside on lawns and landscapes. It works quickly to kill ants, fleas and ticks and knocks down wasps, mosquitoes and yellow jackets.

AS GOOD AS ANY OTHER, WORKS GREAT
Size: 36 sqft, Size: 36 sqft
Used this in my 17 RAM 1500. This stuff works great, just as good as S...ss brand that is also sold on here. Same thickness and same tackiness. And this stuff sticks like crazy, once its laid down and rolled onto the surface, it is hard to remove, so I am pretty sure it will stay where I installed it. It is great value, one box was enough to do the whole roof of the truck with a little left over for small spots. I think it took a total of 2.5 boxes to do my whole crew cab, roof, floor and back wall and most of the firewall, and I also added a layer of their .25" foam. I do notice a difference in less outside noise, from wind and road. I will be doing my wife car soon, and this is the product I will be using again, I recommend this.

Awesome, inexpensive alternative to name-brands!
Size: 36 sqft
Awesome. Stuck well with alcohol prep and time to let liquid flash-off. Very consistent, piece to piece. Backing peeled easily when desired. Compared to Amazon Basics, the butyl seemed a little thicker (infinitesimally) and stickier, foil was less thick than Amazon Basics. Very good value. Started with my nice car, but after completing project, sound dampened all cars in the immediate family it made such a noticeable difference in sound level and quality of music from soeakers. Recommended!

Great sound deadening material with easy installation.
Size: 36 sqft, Size: 36 sqft
This sound-deadening mat was easy to install on the roof of my Toyota FJ Cruiser. It significantly stiffened the roof and dramatically reduced the wind noise inside the vehicle caused by my roof rack and lights. I can actually carry on a conversation again without shouting while driving on the freeway. The 36-square-foot package was enough for my application, with about three sheets left over. The tiles adhered well to the metal without any special surface preparation. I only wish I had done this sooner.
