    5 of 5 stars  Great Stuff
    By Steven in Athens, ga on 04/23/2013
    Verified Purchase

    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.

    5 of 5 stars  Demon EC (Max)
    By Lance in Florida (the bug state) 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.

    By Stan in Savannah, GA 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.

  • 5 of 5 stars  "Demon Max" an appropriate name
    By Arlo in Crystal River, Florida on 05/30/2016

    Used Demon Max to spray yard as the area has lots of farrow cats and they track fleas through the yards. I used demon max with an old bottle sprayer hooked to the hose that mixes the water and concentrate. Doesn't take much time compared to pump sprayer. While spraying I cam across wasps, yellow jackets, etc which I introduced the spray too and they dropped like a rock. I also came across wood roaches chewing around my screened in porch area evidenced by the sawdust. I gave the wood an extra application and they disappeared. Great product.

  • 5 of 5 stars  Awesome
    By Michelle in Montgomery , AL on 05/25/2016

    Since I've used demon max I've noticed a 95% decrease in the number of bugs on my patio. Usually the lights attract bugs an now I don't see them anymore. I've seen 1 cockroach that was dead an maybe 2 or 3 other dead bugs. Since I have a terrible phobia of cockroaches I thought I would need to use more than the suggested amount needed but that wasn't so. I was able to spray my entire house an the outside with a little left over. I have a dog which I thought might be affected but when using the right amount, the odorless solution didn't cause any problems. It dries quick and didn't stain any of my carpet or furniture. I may never have to buy another can of bug spray again. I don't know how long it will last but I'll probably spray again before the summer is over because of my phobia. I recommend this product 100%. Thanks

    By Frank in Dunedin, FL on 05/18/2016

    Fast delivery. Easy to follow instructions. I used a pump sprayer and sprayed the complete exterior and my garage. Eliminates a large variety of insects, some on contact, others take the slow crawl then go belly up. No heavy lingering odor as is the case with many other products. Seems to be long lasting.

QWhich is better, Talstar P or Demon Max?
I am trying to control Ants, Mosquitoes, Wasps, Bees, Flea and Ticks. I used Talstar last year and I am just curious on which is better.

ABoth are going to offer a good kill and a long lasting residual though initially Demon Max may have a faster kill because it is oil based. On the other hand because Demon Max is oil based it could stain old paint/siding and it does have an odor.

QSince Demon Max stains, what color is it?

AThe product is a very light tan. It is the oil itself in the product that will stain so in most cases it leaves an oily residue behind which can stain old paint or old siding.

QWhat is the ratio of Demon Max for mosquitoes and how does it compare?
how many oz of demon max do you use per gallon of water for residual mosquito control, how long does it leave a risidual? and how does demon compare to bifen it?

AYou 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. Bifen IT and Demon Max will have very comparable results for mosquito control though Bifen IT is water based and non-staining and is more widely used by professionals for mosquito control.

QHow much Demon Max is needed to treat x amount of square feet?
I am just wondering how much to order. I have decks and back up to a large vegetation on a veloway. How often do I need to treat etc. that will help me determine how much to order. Thanks

A

Barrier Treatment for Pests around Structures:


Apply Demon Max as a 0.1% emulsion (1/2 fl oz per gallon of water) to a band of soil and
vegetation 6-10 ft. wide around and adjacent to the structure. Also, treat the foundation of the structure to a height of 2-3 ft. Use a treatment volume of 2-10 gal. per 1000 sq. ft.
Higher volumes of water may be needed if mulch or leaf litter is present or dense foliage exists. House siding may be treated if boxelder bugs, elm leaf beetles, earwigs, silverfish
or other similar pests are present. Reapply every 1-3 months as pest pressure builds back up.

QIs Demon Max the best insecticide for all-around indoor and outdoor spider control and termite prevention?
I've been using Demon Max and it's time to reorder. Would Demand CS or Temprid SC be a better treatment? Would you recommend some combination of these?

A

Any of these insecticides would be a good choice for perimeter control of crawling pests. You would not need to mix insecticids as these all have similar active ingredients, and using too much may cause pests to avoid the area rather than coming into contact with the application. An advantage to using either Demand CS or Temprid SC is that these are both water-based, rather than oil-based insecticides. They will have much less odor and can be used safely indoors as crack and crevice and/or spot treatments.

Please see our General Pest Prevention Guide for more information.

For Termite Treatments, you will need to apply products much differently. Please view our Termite Pest Guide for more information about how to Identify, Inspect, Treat, and Prevent Termite Infestations.

QDoes Demon Max work on tropical rat mites?

A

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.

QWill Demon Max protect the perimeter of my home from Brownbanded and American Roaches in addition to Termites?
I am hoping for an all in one treatment. I use Demon WP in my home and love it.

A

Demon Max provides excellent perimeter control of all common roaches and most other common crawling pests, however a treatment for subterranean termites is very different from the treatment for General Pest Prevention because these pests do not crawl on the surface of ground like other insects. The most popular insecticide for liquid termite control that we sell is Termidor SC. Please see our article Subterranean Termite Prevention for instructions on how to perform a termite treatment.

QCan Demon Max be mixed with Talstar/Bifen IT and Cy-Kick CS?
Will it help give Talstar P a longer residual being mixed with an oil base? Will it help to lessen possible resistance by mixing two different insecticides? Should the amount of oz to gal be reduced when mixing the two together in the same tank?

A

Demon Max should not be mixed with Talstar and Cy-Kick CS. Each product should be used alone with water. Mixing insecticides like this could cause the products to be less effective. Cy-Kick CS will give you the longest residual as it is microencapsulated.

QI have been having a problem with earwigs. Would Demon Max be the best product to purchase?
This is our second summer in our home and it is so frustrating having earwigs crawling everywhere. We have sprayed inside, outside, everywhere to no avail....help!

A

Demon Max is a great product to control a broad spectrum of insects including earwigs. We usually do not recommend an oil based product such as Demon Max for indoor use due to temporary staining and odor that it leaves. For indoors, I would recommend using an water based product labeled for earwigs such as Suspend SC, which has virtually no odor or staining. Apply as a coarse, low pressure spot or crack and crevice spray to areas that these pests normally inhabit. Pay particular attention to dark corners of rooms and closets; floor drains; cracks and crevices in walls; along and behind baseboards; beneath and behind sinks, stoves, refrigerators, and cabinets; around plumbing and other utility installations; doors, windows and in attics and crawl spaces. Applications may be made to floor surfaces along baseboards and around air ducts. Let surfaces dry before allowing children or pets to contact surfaces.

If you need anymore information on treating for earwigs, you can read over our guide on How to Get Rid of Earwigs .

QIs Demon Max safe for poultry? Is it safe for them even after it dries? How long does it take to dry?
We got about 25 chickens, 10 guineas and 8 turkeys that are free range.

A

Demon Max  CANNOT be used in poultry houses. Depending on what you are treating for you, can use Bifen IT, as it is listed on the product label to be used in poultry houses. It can take up to 2 hours to dry. Do not apply where they may graze.

QWhat is the mixing ratio per gallon for demon max for indoor spray?
