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.

I am very pleased with how well this product controls my spider problem in my horse stalls. I spray it twice a year and have no spiders. Patrick D.

Really does work!!! I live in Florida where flea season is all year round.. my home was infested with fleas and I mean INFESTED. Anyone who walked on the property would get attacked with fleas and I, myself would get several bites from them a day which would lead to infection all over my body. I sprayed this once a week for effectiveness since it’s starting to rain a lot during the week and my yard is half a acre. Maybe I missed spots? haha Took some time but the infestation calmed down a lot! And the results exceeded my expectations. When it was time to shower my dogs, I’ve noticed they would have little to no fleas on them. When previously they would be filled with them even if I gave them flea medication. This liquid killed more than fleas, it prevented them and several other insects such as mosquitoes, spiders, etc from returning. This really works and wear PPE! Chemical is strong and toxic to humans and pet! I used this small pump sprayer (as seen in the picture) because the gallon sprayers in my opinion were not spraying enough liquid to get the job done and for some reason the gallon pump sprayers wouldn’t last me more than two usages anyways. But anyways I strongly recommend this pair if for some reason it’s not working for you. :)

Works well I live in Florida and bugs from the yard keep getting in but with this it's stopped. Only thing I have spray weekly not monthly because of all the rain probably. But it's working not one bug for 7 months

I had an ant and wolf spider problem outside. The ants were trying to get inside and the spiders were making webs on my door, windows and patio furniture. I finally got sick of useless sprays and tried this. One application and I no longer have any creepy crawlers! Thank you!! I highly recommend this product!!!

So I moved to a new place in Nov, I saw it had a LOT (20+) wasp nests under the eaves. Now that it's getting warm, they WERE starting to come around and build new nests. I did a lot of reading, I guess this is a kind of a wasp (paper maybe) and they build those open honeycomb nests which are primarily under house eaves and porches. I really try not to kill other bugs, especially bees, but since all the nests were away from flowers and vegetation, I invested in this good poison. I sprayed this morning (used just over 1 oz/1 gallon water in a pump sprayer) around 7am, it was 40-45 degrees F out so all the wasps were still asleep. Now that it's warmed up to low 60s, I see quite a few DEAD or DYING wasps who have dropped from the eaves. It sucks it slowly kills them, but I'm sorry, there were so many they were a hazard. I've seen some of the neighborhood wasps coming around trying to find a place to land, but they don't touch anything I've sprayed, I watched em, so this stuff kills on contact and is preventative, just what I was looking for. There are some insecticides similar to this that will kill similar bugs which are safe to use in kitchens, around pets, food, etc.--THIS IS NOT ONE OF THOSE KINDS--this stuff is legit poison, read all instructions and keep away from pets (including grass they may eat, etc). If they still sell it, suspend sc comes packaged like this, does wonders for carpenter bees and flea control (used in MS--it works!). But these wasps called for something else, I wanted something that would specifically kill those. So again, if you have a wasp problem and especially if you're treating small-ish nests (I sprayed ones almost a foot in diameter, but most were smaller) like those ones under overhangs, this is your stuff. And don't sweat the price, with the amount you'll use, it'll last YEARS mainly because it can be used for other bugs too. I heavily sprayed my eaves and then went back around and doused every crack, window and opening to the house, under the porch, everywhere! :D I could not be happier and highly recommend this product!
