I have been using the active ingredient Cypermethrin for almost 5 years as an indoor and outdoor pest control product. It is a great chemical and does wonders to control roaches and ants. The residual effect is nice providing for less applications through the year. It also does not afffect my pets who have shown sensitivity to other pesticides.

Demon EC (Max)
By Lance on 06/26/2013
I have used this stuff for over 10 years; beginning in a rental house that had sat empty for over 3 years and was full of all manner of creepy crawlies. One application of Demon (the first time I'd used it) and they all died a quick and horrible death, leaving the house bug free and inhabitable. It even de-bugged a 18 year old mobile home I lived in while my current house was being built. It's rare for a product to work as well as advertised, but Demon is the real deal.

Best I have used so far.
By Stan on 09/08/2013
Out of all the products I have tried so far Demon Max has proved to be the best. As a landlord of 72 properties, I have tried many products over the years. Demon Max has been very effective and versatile. It has been mixed to do everything I encounter, RoAcHeS, fleas, termites, spiders and ants.

Highly recommend this product. I have been using Terminex services for years and it is quite expensive. I tried Demon Max and it works perfectly. Roaches are dead outside the house and never make it in. I only have to treat the outside perimeter of my home.

My palm trees have been infested with termites and I want to spray the tree, but I also read the soil should be saturated around the tree. Is it safe to use Demon Max or Demon WP to saturate the soil around the tree after spraying the tree?
You cannot use Demon Max or Demon WP to drench for termites around palms, trees, or other plants. This product should not harm ornamental plants, but this is an off-label use and we could not tell you it would be effective. Demon Max can be used to spot treat directly into termite galleries in trees. You would have better success with a non-repellent termiticide, though, such as Termidor Foam, since this product has an active ingredient that will transfer throughout the termite colony.

I have a 1 acre yard. I'm having a grasshopper problem this year. Nothing seems to work for more than a week. I was hoping Demon would last a little bit longer in the yard.
Demon will last up to 30 days on outside surfaces depending on the rain and sun exposure but is not actually labeled for grasshoppers.
Talstar P would be a good choice for grasshopper control and will last up to 30 days as well. You should start applications before the grasshoppers have a chance to hatch for best control. You should thoroughly spray your lawn and water in the application with about a .25 in of water to help the product get past the thatch layer and into the soil where grass hoppers actually develop. If you already have grasshoppers you can use Talstar P at the highest usage rate of 1 oz of product per 1 gallon of water for the quickest knockdown. Use sufficient amounts of water to help the product get to the soil layers.

You should use 1/2 fl oz of Demon Max per gallon of water for mosquito control and you will need to reapply once per month to maintain control. Please refer to product label and our How to Treat for Mosquitoes Guide for more information.
more dead ones but now I got a ton of new off spring in the house.I figured this stuff killed on contact or does it take a while to take affect after contact that I'm not seeing
Per the Demon Max product label, you would mix 1/2 oz to 1 oz per gallon of water. It is not a contact kill. When treating for roaches we also recommend using an insect growth regulator such as Gentrol IGR and a roach bait gel such as the Advion Roach bait gel for faster and more complete control. We also offer a Roach Bait Kit, that contains all of the components you need for a complete roach control program.

I sprayed twice and I still see bed bugs.
Demon Max is not labeled for bedbugs. We suggest applying the products in one of our Bedbug Kits. It will take non-chemical and chemical efforts for a minimum of 6-8 weeks to eliminate this insect. Please take a few moments to review our treatment article on How to Get Rid of Bedbugs for information on a successful eradication program.

For effective control, you should reapply Demon WP or Demon Max (they each contain the same active ingredient- WP will dry with a white film to surfaces treated) every 4 weeks through the carpenter bee season. Usually carpenter bees come twice a year, once in the spring and then again in early fall. Please take a few moments to review our treatment article on How to Get Rid of Carpenter Bees for a successful program.

We apologize but we cannot offer a guarantee on Demon Max as we cannot guarantee that they will be used as directed. We do try to provide as much information as possible on what to expect and how to to use as well as what to do non chemically. We do know they work and you can read previous customer reviews right on the product pages.
However, if the product does not work for you, we try to troubleshoot to see what may have gone awry ,
Demon Max is labed for flea control outdoors only, and it does have a strong odor. You may want to consider using our Indoor Flea Kit instead, which will give you everything you need to do a complete flea treatment. Please take a moment to look over our Flea Control Guide for more information on treating and preventing this pest.

Demon Max is labeled for termites but for a longer protection and control, you should apply a non-repellent liquid concentrate such as Termidor SC, Taurus SC or Dominion 2L. Below I have included a termite treatment article that will be very helpful if you plan to treat them yourself.

I live in Wisconsin.
The Demon Max label (page 7) states that liquid may be sprayed directly into gallery entrance holes mixing at 1/2 fl oz per gallon of water. It is recommended to spray around the holes so when the Carpenter Bees land on the surface, they will pick up the active ingredient. Spraying the whole house would be unecessary and better to focus on areas where holes are already present. Following treatment, the entrance holes may be left open 24 hours to be certain that returning adult bees are killed. When there is no activity, the hole may be closed with wood putty.
