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 sprayed 2 times in the same 24 hrs. I sprayed my entire couch so do I have to throw out the couch? I was finding ticks in my couch because the dogs would sometimes sleep on my couch.
Demon Max is not to be applied on surfaces that come in contact with the skin or on the surface area of the couch. Please contact the manufacturer for instructions on the treatment/cleaning of the couch. They can be reached at 866.796.4368.
We recommend the following for treatment of ticks:
Make sure the property around your home is unattractive to ticks. Because ticks are sensitive to dry conditions and do not thrive in short vegetation, they are seldom a problem in well-maintained lawns. Keep your grass mowed and keep weeds cut. Clean up items that attract rodents which can carry ticks, such as spilled birdseed, and hiding places like old wood piles. If ticks are present in vegetation along the edge of the property, insecticides labeled for control of ticks can be applied to small areas of high weeds that cannot be mowed. Often, one or two applications per season will be adequate to control ticks in these areas.
Free-roaming dogs and cats are much more likely to encounter ticks than those that are confined to the home or yard. If ticks are found on pets, contact your veterinarian for information about an appropriate tick treatment. Remove the occasional tick found indoors by vacuuming, seal the vacuum bag and place it in the trash. Owners of kennels or homes infested with the brown dog tick may wish to contact a professional pest control company for assistance.

Will Demon Max work on crazy ants?
Yes, Demon Max is labeled for interior and exterior use and it can be used to control ants, including crazy ants, that come in contact with the treated area. You should try to treat the colony or nesting site directly. Crazy Ant mounds are not readily visible above ground. Possible nesting sites for Crazy Ants include: soil beneath landscape timbers, logs, mulch firewood and other debris. Crazy Ants may also nest inside rotting wood and tree holes. You can read our article on crazy ants for more treatment information: How to Get Rid of Crazy Ants.

Can I use Demon Max inside the house? I bought an old home and I don't know if there are termites in it. Also, there are a lot of spiders there too that I want to get rid of. Also, when is the best time to apply for termites and spiders? The house is in Missouri and I would like to treat it now but it is very cold here. Would that be beneficial?
While Demon Max will kill most termites and spiders that contact it, this would not be our recommendation for termite control. Please see our Termite Guide. Demon Max can be applied indoors to cracks and crevices. Please be aware since it's oil based it may leave an oily residue. You can always treat indoors. Outdoors, if the ground is frozen, or temps are below freezing or around freezing, it may be best to wait.

For residential lawns, apply Demon Max at the rate of 0.33-0.65 fl oz per 1,000 sq ft in a volume of water sufficient for uniform coverage such as 3-20 gal for mole crickets. Use the lower rate to knock down pests and the higher rate where faster knockdown or greater residual is desired. The maximum application rate on lawns and other turfgrass is 0.44 lb ai/A (0.0101 lb ai/1,000 sq ft). Lawn should not be longer than 3 inches at the time of application. You can add a surfactant to the mixture for more effective results.

Demon Max would bond to the soil for up to 5 years. While it is labeled to be used in a trench application for termite control, it is not a recommended product to treat and/or prevent termites. Demon Max will only kill termites that contact treated areas, it is not able to be transferred throughout the colony to eradicate an entire colony. Taurus SC or Termidor SC are the products of choice for subterranean termite treatment. They will bond to the soil for up to 10 years and are able to be transferred throughout the colony by the affected termites to eradicate the entire colony.

You cannot use Demon Max down a drain. Demon Max can only be used for crack and crevice and spot treatments; in, on, and around structures and buildings; on lawns, turf, vegetation, and soil; surrounding and under building foundations.
If you are trying to treat for your fly and drain problem please refer to and use the Drain Fly Kit. The Drain Fly Kit with Invade Bio Drain Gel will treat up to two infested drains and includes CB-80 Aerosol to control nuisance flies during the treatment process, plus 12 Catchmaster 100i Insect Monitors (Pack of 4 boards that split) to monitor infested drains. CB-80 Aerosol will shoot out in quick misting spurts that will allow you to spot treat around sinks and drains and in open areas.

Demon Max can have some knockdown properties, but it is not considered a contact kill product. It is a residual insecticide that once dry will last on the surface 90 days indoors and 30 days outdoors. However, this product is not labeled for gnats. You could use a product like Talstar P. You may want to look over our article on Getting Rid of Gnats for more information.
