Worth the investment. We had our house professionally sprayed for cockroaches and saw that they used this product. To save money, we bought the same thing and use it to regularly spray our townhome! We have never had any issues with our dog and it seems kid and pet safe when dry. We had a bad infestation when we first moved in. After a few treatments, it was under control. Now we spray every few months to keep them away. It’s easy to use - just spray around edges. We focus on our kitchen island and some outdoor places/doors. It’s a great value since the jug is a concentrate - it’ll last forever! I’m glad we made the investment to take care of our bugs ourselves for years to come. We can also use just this without any bait/gel, so that’s a cost saver!

Good product. I was having trouble with brown recuse spiders constantly. I used Terminix which cost me around $100 every 3 months and the spiders would come back after month 2. I spent a total of $130 in products to safely do it myself and it will all last me for at least a couple years! So far it’s been about 2 months and I haven’t seen a spider yet. This stuff seems to work great! Plus I was able to apply it in the attic and other places Terminix wouldn’t go. Just make sure you follow the safety suggestions And be smart about it. It is some nasty stuff. I got a full tyvek suit, gloves and mask to safety apply and did not apply it in the house at all except for the attic.

Amazing product! I use as directed and spray the perimeter of my house, eaves, and around the windows. We have so many Box Elder bugs and Asian Beetles in our neighborhood which are no longer a problem for us and no longer sneak into the house in the fall. A few years ago, after spraying, there were hundreds of dead Box Elder bugs laying on my deck that had crept out of of crevices. Since then the amount of bugs I even see around the house is drastically reduced. This year, my son's house had millions of baby Box Elders around his shed and landscaping. Immediately solved that problem and this fall, I saw just a couple adults that were on his house. It kills spiders etc. too, and works a long time due to its residual potency. Neighbors hire pest control companies to spray, but I save hundreds by taking 20 minutes and doing it myself. One bottle lasts several seasons. Bonus: No strong odor.

Works. Sprayed in January. Now that it’s starting to get warmer i see all sorts of roaches trying to make their way into my house just to end up dead a few feet past my entrance. The residual affects are pretty good. Only thing i don’t like is the horrible smell. But once dry everything is good.

My wife, daughter and I moved into a home in the woods last fall which previously also had a trailer on the land which was left unoccupied and uncared for for 10+ years before it was bulldozed. The neighbors told me that the guy who bulldozed it had to be sent to the hospital due to wasp stings since the trailer was infested with them. Last fall, when we had a warm streak peaking temperatures in the mid 90s, I learned that those wasps had taken up residence in my attic and the surrounding woods. I killed over 100 wasps per day for a week with a fly swatter and a can of bug spray - the wasps did not seem to decrease in numbers even with my killing spree. I ordered this product along with another product called Taurus SC (Fipronil) from Amazon after Terminix failed to do anything that even remotely improved the issue. After spraying both products along my eaves, windows, and foundation, I noticed a marked decrease in activity within 24 hours. After one week, wasp activity had decreased by more than 90%. This spring, I started early and sprayed both products along the same areas of my house. I've not seen a single wasp crawling into my attic vents and what wasp activity I do see is limited to one or two wasps per day which I chalk up to foraging activity from nests deeper in the woods. They absolutely steer clear of my house now. As an added bonus, this combination of products has kept out ants, fleas, and scorpions (all my neighbors have them in their houses this year) so far through this year. It also seems to have a favorable effect on mosquitoes and spiders. I keep referencing the combination of products as I can't pinpoint which is 'more' effective. What I can say is that I bought both of them with a notion of a 1-2 punch: Onslaught kills the live creatures effectively and Fipronil (http://www.amazon.com/gp/product/B0058DGMKG?psc=1&redirect=true&ref_=oh_aui_search_detailpage) is a baiting agent acting as a neuro inhibitor which community insects take back to the nest. For some additional anecdotal praise; My wife is a Real Estate Agent and visits, sometimes, dozens of houses in a day. This time of year, she goes equipped with wasp and hornet spray as nearly all houses in our area (even nice, occupied homes) have wasps buzzing around the doors. I knew this product (and the accompanying product) were successful when she told me she doesn't have to worry about wasps when she comes home. Now that's an endorsement! For reference, I live in the West River Valley region of Arkansas. The wasps I had problems with were Red Wasps, Yellow Jackets, and Ground Hornets. I only applied this product externally, though it's labelled as safe for interior use. I spray both products once every 30 days. I mix each of the products separately, as I do not know if they would maintain efficacy combined in a single solution and am not interested in breaking what's working. :)
