  • Best product for bugs in the home
I love this product in my house and outside my home for keeping bugs out of my house, I have used it for several years and it works great. I have never had a problem with bugs using it in or around my home!

  • Fantastic
The product works very well! When the exterminators find out that you use this, they just put there head down with disappointment:) Thank you for this great product and keeping the price reasonable:)
Reviewed in the United States on September 20, 2023 by This is great stuff and works so well! I have to laugh a little when the exterminators come to my door once in a why and ask if I eat to sign up for there services. I inform them of this product and they just look down at the ground and take a breath. They know this is the best on the market and for such a fantastic price:) Thank you for keeping the price so reasonable!

  • Demon insecticide
This is absolutely the best insecticide I've ever used. It kills everything and lasts for months. It doesn't have that gross insecticide smell either. Awesome product

  • Hesitant at first but…
Read the instructions word for word. Wear your PPE-rubber gloves, safety glasses and a filtered mask if you got one. My Dad told me about this product. I live literally “Out in the sticks by a creek” so you can only imagine all of the flying insects coming around. Two or three days after spraying Demon around and on the Eve of my house, I’ve seen little to no flying insects. Mosquitos, wasps, yellow jackets etc. If you have fireants like I do, kick the top of their mound off and spray/soak where the mound was. Wait a bit, come back and there will be no live fire ants, just a black spot. This stuff is highly potent and works way better than I expected. Repeat every three months as stated. Extremely pleased with the outcome of Demon. Best of luck. T.H. ... show more

  • Works great
Works great! Note tho: Must use a MUCH stronger mixture than package calls for, to work 'great'. Otherwise it's only 'OK', and temporary. Halve, or less, the water mix ratio on the package. Make sure to spray UNDER things....stuff will wash off naturally with rainfall and time if you don't. So far i've been carpenter bee free since spraying underneath the edges of my roofing. It's lasted for three months now; so far so good. Already bought more, to treat more problem pest areas. ... show more
