Harris Scorpion Killer, Liquid Spray with Odorless and Non-Staining Extended Residual Kill Formula (Gallon) 128 Fl Oz

We live in Texas behind a green belt where we consistently encountered bark scorpions making their way in our house. When I first bought this spray, I hesitated using it right away because I wanted to call in a professional to assess the situation. While at the house, the exterminator noticed the spray on the deck, looked at the ingredients and was so surprised - He said it had almost all the same ingredients as his own spray, and that we could probably just upkeep with this after he did the initial spray. Well, after the exterminator sprayed his product, the scorpions kept making their way in, it felt like it actually got worse even after weeks. I had to call him back 2x to respray because we were seeing even more throughout the month. I stopped calling him and instead finally decided to use this stuff instead and that was the best decision that I made. After spraying, It stopped the scorpion sightings almost immediately. If we do see a scorpion, they're normally already dead by one of the doors outside or in the garage. We can always tell when we need to respray when we do spot an alive scorpion outside, but once we spray again, poof all gone for about 2-3 months. I'm so thankful for this product, offering peace of mind from my scorpion trauma. It's been a game-changer and the price really is exceptional for the quality.

So far, so good. For those complaining about this not killing immediately: that's not how residual sprays work. After the spray dries, the bug walks through it and it gradually kills them. If you want a kill on contact spray, buy one. I have roaches and scorpions in my new place and sprayed the hell out of everywhere. Haven't seen another scorpion yet. The smell is minimal. Make sure you close the nozzle or you'll end up having a leak everywhere if you leave the bottle unattended. Whoops. At least it happened outside.

Recently moved to TX to a brand new construction. We before buying this, we had seen over 4 scorpions and numerous spiders. We have been using it for the past 2 months and no more scorpions! The few spiders/bugs we have seen are dead or almost dead. We spray outside and indoor and lots of the bugs die trying to get in.The applicator is not the best but at least the product works and it’s odorless.

It kills scorpions, but of course the real issue is, will this work for more than a couple days? It appears so. Scorpions are notoriously hard to kill, so it's a valid question.When we moved into our current home in Arizona, it seemed like scorpions were everywhere. It took years to reduce their presence, because however many you kill, the eggs won't be killed and they will hatch. It's not the insecticide's fault. You can either pay $$$/month for pest control, or buy this a couple or three times a year. It takes some time & effort, but it works.

This stuff is pretty powerful and sells for the right price. However, there is a major flaw in the sprayer. If you do not force the tubing all the way back into the bottle immediately when done using it, it will leak majorly and it leaves a residue that Im sure is toxic! Also be aware that this stuff will burn your skin on contact so sensitive skin people need to be aware of possible chemical burns with contact. But it does what it’s supposed to do for sure!
