    Quick kill- Weak residual

    By G on 08/07/2013

    Verified Purchase

    I'm confident you will love the quick kill on spiders and especially paper wasps! The residual of this product is almost non-existent. Spiders were back to rebuilding webs a couple days later. It's a good product, but just it's not the miracle product others have claimed it to be.

    Happy Customer

    By Jp on 02/19/2016

    I have been using Onslaught FastCap for over two years. My home had a problem with scorpions and we sometimes find them inside. I would spray everywhere inside my garage as well as a 5-foot perimeter around my home up the side and out along the ground...it works. It last for about 3-months. Although it did not totally eradicate the scorpions issue I do see less scorpions because this stuff kills the bugs that scorpions eat. When you use this product in conjunction with cleaning up debris around your home like fallen leaves and piles of trash or wood you will greatly reduce their population.

    Better Than Others

    By Carol on 07/18/2017

    We see way less scorpions than before I started using this product. I pay a company for monthly service, but was seeing just to many scorpions in my home. We had a different company come out and sealed our house. That took care of the scorpions getting in, but still saw them a lot of them outside. Started using this product and the number of scorpions outside has been reduced.

    Great Service Great Product.

    By Paxton on 11/12/2015

    I would give 5 stars for the service. Shipping was fast. I can only give 4 stars on the product because I've not had time to see how good a residual it is and I used it closer to the end of higher pest season (used it 2nd half of Oct. at mothers home in Bullhead city, AZ). It did prove effective on crickets around the house. I like that it dried clear on base boards and walls (no staining paint). I would reccomend it and look forward to using it again.

    Onslaught review

    By Mark on 05/29/2020

    This is the first product that I have used that was effective in killing both black widows and brown widows which has plagued my yard for years. I needed something that is safe for dogs and this did not cause any problems or leave any odors. Hopefully it will have a sustained effects. Great product. Also, customer service was very knowledgeable and helpful in explaining the comparative advantages/limitations of this product compared with others which was very useful in determining the best product for my situation. I will definitely recommend this to others.

    Onslaught FastCap worked great in Michigan woods

    By Matt on 07/20/2018

    Onslaught FastCap worked great! I sprayed it around our home in Michigan to keep the crawly critters out. My main concern was with Deer Ticks, Fleas and Spiders for our small dogs. I have not seen any of them. I followed the instructions and the results have been great. 3 weeks now and NO spiders or anything else around the house. I sprayed my grandparents house to and they are enjoying the same great results! They had a problem with Asian Beatles, now the Beatles are gone. If you live in the woods, I highly recommend the Onslaught FastCap.

    early to tell but shipment fast

    By Sandra on 12/05/2013

    Verified Purchase

    too early to tell... just prayed... time will tell how effective the insecticide will perform. I do have high hopes. Shipping time was fast. The mixing went well... knowing what is getting sprayed in the real value here. I think some "bug guys" just spray water and charge. I KNOW ITS INSECTICIDE!

    Best for arachnids

    By Jb on 09/25/2020

    Best product for spiders and scorpions by far. Not labeled for fire ants which sucks.

    a bit of short from 16oz

    By Azmi on 10/19/2016

    Verified Purchase

    this is an excellent product. i would like to give it a 5 star rating, but my last purchase was a bit less than 16oz. being so expensive, even a fraction of an ounce matters a great deal.

    Good Product

    By Will on 07/06/2016

    I tried tried this product since I didn't want to pay a monthly service for something I can do myself. It had good reviews, so I gave it a try. Measuring cup built in makes it super easy to mix. Product does great killing bugs and no staining or visual residue. Verdict is still out on killing scorpions, I don't have a infestation I've seen about five and I killed them using backlight, but since I sprayed I have seen 2 more so not so sure about scorpions hence the 4 stars, but it kills the flying and American roaches! All in all a great economical product vs $30 + monthly service.

    Spider control for cameras

    By Joe on 11/27/2015

    Bought this to see if works on spiders . First time spraying, spiders were coming out of cracks by the dozens ! I knew I had a spider problem but not that bad ! I am very happy it leaves no indication of where I spray ( goes on clear and dries clear ) . I bought this mostly for my surveillance cameras since spiders seek a bit of heat to live and such. Works somewhat okay but I still have to go out daily and remove the webs off of them even though it killed the spiders. Overall a good product and I will keep using it for the time being .

    First use

    By Michael on 07/31/2020

    Living in Arizona scorpions are always a concern. This was my first purchase of this product. Used it for exterior perimeter spray application. It has been a couple of weeks and there have been no "intruders" to date. As I was going out this morning I saw a larger insect that had crawled into the "death zone" where I had sprayed and it was in its death throes. The real test will be to see how long the product lasts.

    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!
