5we had infestation until i got OnslaughtAug 11, 2011
By whitedove1968
YES! YES! YES! BUY THIS PRODUCT...Skeptical at first, but then?? WOW!! i can actually go back outside again!! it was a bit expensive but i was at my wits end. i couldn't even go outside without getting divebombed in the head by some kind of wasp or bee. i did ALOT of research on yellow jackets and couldn't find the nest, and really didn't want to start walking around out back so i would "accidentally" find the nest and end up in the hospital with 100+ stings that you hear stories about!!

i ordered Onslaught, and with 1 can of tuna and some containers and a little string, hung them up in the yard in trees (high enough so dogs couldn't reach them-very dangerous to animals!) and waited...and waited...and waited... about a week later i noticed the numbers were getting smaller and smaller.. today, in the heat of the day (high time for activity) i stood on my porch for 1/2 hour and not a bug in site!!! WOOOOOOOOOOOHOOOOOOOOOOOOOO!!

i used the recommended amount, (bottle will last a long time-YEARS) which is just a little bit compared to the bottle, and voila!!! NO more wasps!! NO more hunting for holes in the grass in the evening! and then trying to plug with hole with a bottle of gas!! i think i'm gonna cookout tomorrow because i can go out on the deck again!!

2Not as good as fipronil for yellow jacketsJun 23, 2014
By Diana S.
I used this for several years to bait yellow jackets. It did seem to help a little but not a whole lot. Then I read a report put out by UC Davis looking at different insecticides and baits for yellow jackets. You can search on Google to find it. They found that Onslaught didn't work very well, but an insecticide named fipronil worked much better (offered on this website too). The best baits were Swanson's canned chicken and Friskies Ocean Whitefish, and you dilute the fipronil to 1:1000 final dilution. OMG, how much better fipronil worked than this stuff, the YJ's virtually disappeared within 72 hrs. If you are buying Onslaught for YJ's, I think you should look elsewhere.

5Wonderful stuffApr 10, 2012
I used this last year when I had a bit of a scorpion problem. I had purchased a home that was a short sale, so I think the arachnid population was a bit out of control.

After searching out via black light the main hot spots, I proceeded to make a slightly more concentrated mixture.

I hit the hot spots with quit a bit and then did 10 foot stripes from my back fence to my house. I then did the entire perimeter of my home, went around the foundation, all doors and windows and eaves ( between the wall and roof ) and any other locations that I thought might give potential access.

After about a month and a half I stopped seeing scorpions. I have seen two ( 2 ) dead ones in corners since I sprayed.

I plan on spraying again this year again to maintain the bliss of a scorpion free home. :)

A great product that actually works and is cheaper than having a professional do it.

5Great product.Apr 03, 2013
This is a great product. We had a tick problem in our back yard and our dog carried some inside. It took a few applications with a cheap sprayer but the problem was eliminated outside and in.

5Professional StrengthFeb 12, 2014
By Tom1wookie "Tom1wookie"
I have used this for four years now as a basic pesticide for my whole house. I mix it 1 oz per gallon of water in a hand pump sprayer. I put down a foot wide barrier up the side (from the ground) of the house, inside the breather holes, and on the underside of the eves. I also spray the floors around the walls in the house. Of course put the pets up until it drys. Use it every 3 months. Bottle lasts about 2 years. I purchase this from a local exterminator who gives me a military discount so it's just a little cheaper than Amazon but this stuff works! Earwigs were my worse. Haven't seen but one in four years. Centipedes were next but I see one ever year. Guess they pass over it so fast they get in before the poison takes affect. Even the hard to kill spider population has gone down with this stuff. It is definitely cheaper than paying an exterminator $50-$90 each quarter. An it only takes an hour to prepare and spray the house. Be sure to use protective equipment like rubber gloves, mask, and eye protection. I'd also ware long sleeves and a hat.
Highly recommend this if you have a pest problem.
