    Amazing for Springtails

    By Steve on 08/11/2023

    Had an issue with springtails coming into my master bath after a period of heavy rains. Nothing I did could really curtail them, at any point I'd have 10-20 crawling around on the floor, vacuum them up, back in a few hours. Talstar/Bifenthrin was completely ineffective against them. Heard a recommendation to use this, did a treatment on that side of the house on the foundation wall and siding. Two days later, I saw the last springtail and haven't seen one since, and it's been weeks.

    Using for residential insect control

    By Richard on 09/23/2023

    One acre residential property with woods surrounding. Used with a 20 gallon tank sprayer towed. I have used before for tick control and been satisfied. This year we had an abundance of mosquitos and decided to give it a try. Noticed a huge difference for about 5 or so days, basically eradicated all the mosquitos that were so prevalent. I was hoping there would be residual effects for any new mosquitos that would slowly migrate out of the woods (and some wetland). However within about a week, a new crop of these pests were back in control of property. I kind of expected this to be a temporary fix, but at least gained some satisfaction knowing I killed the few hundred mosquitos that had been attacking us all summer!

    FastCap

    By Yvonne on 10/14/2023

    Not very impressed with FastCap. I sprayed all around my house, around windows and everywhere I could spray. I sprayed in my house, especially in my bedroom because that's where I've been bitten. 3 days after spraying, I got bit again so I don't know what the problem is

    Expert Response  Expert response:
    Onslaught Fastcap is a great option to use for many different pests. Depending on what insect you are treating for, other products may be required and repeat applications as well insects will still be seen in the area as it does not truly repel them. As long as insects contact the treated area they will die but it takes time.

    Onslaught

    By Mcelroy on 10/20/2023

    We live in the country so we have lots of spiders & scorpions. I've tried Demon 7 & others but Onslaught is working the best.

    Great product!

    By Rick on 01/26/2024

    Amazing insecticide! We have an abundance of scorpions where I live, so I spray it about once every 4-6 weeks all around my house. It has done a tremendous job in reducing the amount we see outside or in. Word of warning though; if you don’t want to kill every other crawling insect, don’t use this stuff. It is always a surprise on just how many other dead bugs I see after spraying. Definitely does it’s job!!
