Found out after seeing a bark scorpion by our front door and grabbing a black light at night that we had a significant issue at the place we were renting. Toddler at home and pregnant wife …the last thing i wanted was to have a bark scorpion get inside and sting one of them. I had also stomped on a few trying to get in through the front door to make matters worse. The time for war had come commmence operation . I called a friend of mine who used to work in pest control on the best measure to handle them.. he recommended demonex. I got the spray pump canister ready that I had purchased..put on long rubber gloves and he’s a respirator system because it is toxic stuff be sure to cover your body and if any gets on you especially skin even a small amount of the mixture you need to wash heavily with warm water and soap for 20 mins.. so make sure to plan accordingly and protect yourself before using this. In other words using demonex to kill scorpions wearing your pool Speedos is not recommended. I was told to create a barrier up about 5 feet onto the house and out about 3 feet down onto the ground surface.. I used double potency because these are scorpions and these land lobsters have been around for quite some time for a reason .. it ain’t because they die easily. Went with double the potency mixed the tank.. and walked backwards spraying the border along the house and base of the outside floor perimeter surrounding it.. while also black lighting and hosing down every single nefarious scorpion that glowed in my way.. which was plenty. Upon hitting the scorpions they immediately were deleted and yeeted.. I went around the house walking backwards while spraying and then killing anything around the perimeter that glowed in the dark. (Scorpions light up like a glow stick when using a black light at. Night) . Went around the front of the house and killed at least one panzer division of scorpions..while sounding like darth Vader using in my respirator. I proceeded around all areas of the houses perimeter and systematically destroyed my enemy scorpions. I was the Rhodesian republic they were communist insurgent scorpions (in my mind). The victory was so glorious that I am proud to say operation neutralize Arizona bark Scorpion land lobsters was more than a success it was like Agincourt they were the French …the scorpions didn’t show back up for the remainder of my time there. This demonex seriously works.. it is potent stuff be very careful making the mixture and using the pump that you do not accidentally release pressure and allow any of it to escape out and get anywhere it shouldn’t. It immediately suffocated the biggest dam bark scorpion I’ve ever seen in my life which happened to be having a hippie jam festival with his smaller putrid land lobster friends right by my front door on a pillar. Goodbye! . This will take care of your issues.. just spray accordingly create a barrier and walk backwards as you spray up and down on the side of the house and then then the base of rhe house on the ground. It doesn’t smell great at all why would it? Don’t smell it !? it’s a very effective class c pesticide so make sure nobody kids or dogs get outside for a solid 2.5 hours after spraying and if they do get in and out fast and avoid hanging around the barrier… great value for the money.. one can fully treat their entire house for not just scorpions bu all pests doing this method to keep them away and to also handle a problem. Again, Do wear protective gear it is toxic after spraying it is a seriously effective pesticide so again keep that in mind. If it’s any help as well.. you can also apply natural diamatreous earth, the powder into the corners that the putrid land lobster scorpions tend to get through. This stuff dries them out and also repels them and this is a natural way to add to your defense. You cannot go wrong with this demonex pesticide but just make sure you realize you are not handling windex or simple green… if ANY gets on your skin immediately stop and go to soap and warm water scrub the skin for a solid 20 mins that is how careful you need to be. This will be an effective battle strategy to win whatever pests you may be facing and to create a force field around your home. Take care. 100% recommend.

This product works great. I would recommend 10/10
Reviewed in the United States on July 3, 2026 by Clone
First, I gave this a 4 instead of a 5 due to the premeasuring bottle design. Today's engineers and product designers lack sense when trying to make such things convenient for the consumer. I despise these bottles because they never work right nor pour well. In fact they make it more hazardous. Ok -- This is the only large-scale spray insecticide I have tried that works on Crazy Ants, which I have battled for many years. Crazy ants are especially bad because they're non-native, males can become reproductive queens if necessary, their diet changes from seeking sweet baits to protein-baits, and they love to nest in the walls of a home. So baiting doesn't work well unless you provide both, and often invites other bugs or creatures. Only nuking them with a WMD like this works, and generations tend to stay away from areas you've sprayed due to probably the smell in the soil, although undetectable by humans.

The company is great to work with and the product kills the bugs. I had a question and they responded quickly and throughly answered my question.

Kills bugs in DROVES. This stuff is frighteninglybeffective. As you can see from my video, there isn't a bug flying around any exterior light I have, and I'm in FLORIDA. It's easy to mix, effective and affordable. What's not to like? There isn't a spider crawling anywhere, because demon Max works even on bugs that don't groom themselves. There isn't a single palmetto bug or any ants in sight. There are no mosquitoes flying around. There isn't a single bug within 200 ft of my house as far as I can tell. If you use this, it will work. On anything.

Excellent product. Arrived quick and was well packaged. I was worried about receding an old or open bottle but it came fresh and sealed. Super helpful for killing stink bugs and carpenter bees.
