    Q
    FastCap Onslaught and ants
    I tried Onslaught FastCap for the first time at a dance studio that has ants under their dance sub floors. The floors could not be broadcast sprayed and I could not reach under the sub floors, so I did a baseboard crack and crevice treatment and hoped for good results... It has been about a week and they report no change in ant activity. So I have several questions: 1. Is that enough time to see results. 2. Do you have any application recommendations that might help? 3. Are there any other product recommendations that would produce excellent results? Many Thanks!
    A

    1. It can take up to 21 days to start to see big results

    2. Yes, while Onslaught will kill ants that come incontact with it, Onslaught will not stop the problem. If you can bait then please check out the Complete Ant kit. If not then Phantom would be a good product to use. Pests can't even detect Phantom, so they walk right over it and then spread it to other insects hidden behind walls or in their home colony, killing every other pest they come in contact with.

  • Asked by Darren from Dartmouth Ma
    06/02/2019
    Q
    What is better for foundation spraying, Onslaught or Talstar P?
    I just made a purchase for Talstar P and used it to spray the yard and foundation. Does Onslaught Fastcap kill the spiders faster than the Talstar P?
    A

    Onslaught FastCap Spider and Scorpion Insecticide will kill those insects that are sprayed directly faster than just Talstar alone due to the 2 synergists it contains.  It can also last longer on outside surfaces (up to 60-90 days vs 30 days) and is easier for spiders to pick up so that they get a direct hit of active ingredient.

    Q
    Can I mix CyKick CS and Onslaught FastCap Spider and Scorpion Insecticide for maximum effectiveness on scorpions?
    A

    Onslaught FastCap Spider and Scorpion Insecticide and Cy-Kick CS should not be mixed together. Using either of these products will do a great job controlling scorpions. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation

  • Asked by Kevin from Mead, Wa
    06/22/2017
    Q
    When doing an interior treatment for spiders, will I get better results by using a fan spray (close to the baseboard to basically just cover the baseboard) or applying a pin stream near the bottom of the baseboard using Onslaught FastCap?
    A

    When applying Onslaught FastCap to baseboards and interior crevices, we suggest using a pin stream. Fan spraying will be great for outdoors where you have a lot more surface area to cover.

    Q
    Howdy there. I am excited about trying this product out - reviews have been extremely helpful and useful.
    I hope this eliminates my scorpion issues. Can I use this product on hardwood floors, mainly by the baseboards? Also, with other products a white residue is left after application. if I spray down this product, will mopping and/or waxing my floors eliminate the potency of the product; in other words would I have to reapply and essentially just get used to the white residue? Thank you! you have a great website
    A
    Onslaught FastCap Spider and Scorpion Insecticide cannot be applied as a broadcast over hardwood floors, but can be applied to the baseboards surrounding the hardwoods floors. cracks and crevices. Mopping or waxing will remove the product. Onslaught fastcap dries clear and should not leave a white residue. Please let us know if you have any more questions!

  • Asked by Rich from Worcester, Ma

    Q
    Will Onslaught Fastcap Spider and Scorpion Insecticide also work for springtails?
    A

    Yes, Onslaught FastCap Spider and Scorpion Insecticide is labeled for springtails as well. You will use 1 fl. oz. per gallon of water. Because they are usually a garden pest, keeping springtails outside of your home is the most effective way to keep a large infestation from occurring. The best way to achieve this goal is to treat the exterior of your home with some kind of barrier insecticide. Make sure you spray around the perimeter of your home, windows, doors, etc. where the pests can come inside.

  • Asked by Pam from Mcdonough, Ga
    07/13/2015
    Q
    Is Onslaught FastCap Insecticide the best way to get rid of scorpions?
    We find scorpions in our house all the time in various areas. I have a 7mo. old grandchild starting to crawl and a small dog in the house. I can't take a chance on my grandchild being stung by a scorpion.
    A

    Onslaught FastCap Spider and Scorpion Insecticide would definitely be the best option for your needs. It is specifically formulated to better target spiders and scorpions with a more thorough and long lasting coverage for these hard to kill pests. Keep in mind, no matter what product you are using for scorpions, you have to create a wider barrier for them than any other pest around your home. For general insects you would treat with a barrier around the foundation 2 feet up and 2 feet out. With scorpions you should be doing 2-3 feet up and 6-10 feet out on the ground. You can also spray inside around cracks and crevices, baseboard areas, and potential entry points such as around window and door frames and where plumbing meets the wall.  Also make sure to treat any landscape areas around your home that they would be prone to hiding in, i.e., mulch, bark, landscape timbers, rocks etc. You can review more information for protecting your home from scorpions in our article on Scorpion Control.
