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.

I spray using a back pack gas operated sprayer (Stihl 450SR). I use Demon Max to control mosquitos but want to have the option for adding a product to it for controlling biting deer flies and horseflies
Demon Max is labeled for flies and there is not another insecticide we would recommend mixing with it. ExciteR could be added to it to give a faster knockdown during initial application though. Horseflies and many other species of biting flies tend to develop on the edge of bodies of water and since they are strong fliers these breeding areas can be near or far which makes finding the source next to impossible. Using Demon Max will give some relief but since these flies can fly over treated areas it can be tough to get complete control. Relief should be on the way soon, however as horsefly season is usually only 3-6 weeks long.

Will it break down quickly like Bifen does under strong UV rays? Looking for an exterior product that will last at least 30 days under extreme 100+ degree heat.
It will be difficult for any product to last over 30 days in extreme heat and direct sunlight, however, we would recommend an encapsulated product for the longest residual. Demon Max has an oil base, while the Bifen IT is a water-based insecticide (Bifen XTS is oil-based). It may last a bit longer than Bifen IT, but would have similar residual to Bifen XTS. Great options for longer residual in more severe weather would be either Suspend Polyzone or Cyzmic CS.

Demon Max is not labeled to be used to treat for mites. We advise to find the source of the infestation and removing the infested nest and doing a thorough cleanup is necessary. For treatment in the home, we recommend you frequently vacuum all carpet and upholstry and dispose of the bag of vacuum contents in a sealed bag outdoors. Spray Sterifab on couches, chairs and other upholstered furniture where you may spend time resting. Use Cimexa Dust in all cracks and crevices around the perimeter of the room. Apply a thin coat of MotherEarth dust to rugs and carpets. Rake (not sweep) back and forth, causing dust to enter rug or carpet. Let product sit overnight. Repeat application as necessary and vacuum every 3-4 days for effective control. Onslaught can be used for a faster knockdown. Thoroughly apply as a fine particle broadcast spray using a hand pump sprayer to infested cracks and crevices around the perimeter of each room. Put all clothes through the dryer on high heat to help kill mites and their eggs. We have had many customers use the above recommendations with great success. Most customers report that it could take several months to get rid of all the mites. Finding and removing the source of the infestation is very important and is the key to getting rid of the mites.

I have a serious chigger problem in my yard. I tried some spray from a local box store but the problem has only gotten worse. Can I use this product with a hose attachment or is it best used in a pump sprayer? Do you recommend this for chiggers? I'm at the point where I'm about to burn my yard to the bare earth! Unfortunately the dogs and my girlfriend wouldn't approve. Any help is appreciated!
I sprayed a ground nest of yellow jackets last night with the product. Later that night it rained.
The active ingredient in Demox Max is Cypermethrin. Cypermethrin is in the synthetic pyrethroid class of insecticides. It is a man-made active ingredient that attacks the central nervous system of insects that come in contact with or ingest it.

Demon Max is labeled for flies and should be applied 25 ft away from any bodies of water. It may only provide temporary relief for where the insect lands. For the Buffalo Gnat nest, you want something that will provide an instant knock down like CB- 80 aerosol.
Demon Max is labeled to treat for roaches and other common insects. It has a residual of 90 days indoors and 30 days outdoors. If the odor of Demon Max is too strong for you, take a look at Talstar P. It is colorless and odorless. It also has the same residual and is labeled for just about any insect. Please keep in mind that we do not recommend using only a spray such as Demon Max for eradication of a roach infestation. Please take a few moments to review our Roach Treatment Guide for assistance on how to treat for this pest successfully.
