Yes, Demon Max will work for spiders, including black widows. Please take a look at our Spider Control Guide for more information on treating and preventing this pest.
Demon Max is safe for pets and humans once dry. As long as it has had at least 6 hours of dry time before rain or irrigation it wont be of any concern for pets if they go through an area that was sprayed that becomes wet.
Per the Demon Max product label for lawn and landscape pests such as Chinch Bugs, Mole Crickets, Fleas, and Ticks: Application in combination with compatible surfactants may enhance penetration. Otherwise one would not be needed.
Yes, Demon Max would be a good option for cicada killer wasps. The mixing rate is 1.3 fl oz per gallon of water. You will apply directly to the soil where the wasps are nesting.
Cicada Killer wasps thrive in disturbed environments, such as landscaped yards and places where bare soil is exposed. You can discourage the wasps from nesting in your yard by cutting your grass on the highest setting and by adding a thick layer of mulch to flower beds during the Cicada Killer Wasp season. These wasps do not like over saturated lawns either, so over watering during their season will help prevent them. Unfortunately, there is no fool proof way to prevent cicada killer wasps.For prevention you can try to use a granular insecticide such as Talstar PL Granules in the couple of weeks before this pest is known to emerge. For current infestations, you can also use Delta Dust in each individual burrow.
We also like to let our customers know that the Cicada Killer wasps are beneficial insects that provide free pest control for a couple months each year. Cicada killer wasps paralyze and provision their burrows with other insects to feed their young. The beneficial Cicada killer wasps, while large and intimidating to see, are mostly harmless and there have been very few reports of anyone getting stung by just being near them. In most cases where a sting was reported, the wasps were being held or molested in some way. Cicada Killer Wasp stings are also reported to be almost painless.
Demon Max is mixed at the rate of 1/2 - 1 oz for cockroaches. You may want to look over our Roach Control Guide for more information on treating and preventing roaches.
Demon Max is a dark brown viscous liquid concentrate.
Demon Max cannot be used indoors or on carpeting. If you would like to give us more information about what pest(s) you need to treat, we will be happy to recommend an alternative product.
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.
Demon Max will kill leaf cutter ants that are directly contacted with the spray but will have no result on the ants that stay in the nest. Leaf cutter ants can be a difficult pest to get rid of. The colonies are large and the ants make their own food so poison baits only have limited effects on this species of ants. According to several university websites MaxForce Ant Bait Granules containing hydramethlynon are somewhat effective, though they will usually eliminate only about 30% of a large colony in one treatment and will need to be reapplied several times. DeltaGard Granules are one of the only products actually labeled for leaf cutter ants. The product label recommends treating the mounds directly and lightly watering the granules in. Again, it may take several treatments to get the desired results. We also recommend contacting your local cooperative extension office to see if they have any recommendations for products that have worked for other people in your region.
Demon Max will kill most species of cockroaches, including German cockroaches. Please take a look at our Roach Control Guide for more information on doing a complete roach treatment.
The maximum rate for general insects using Demon Max is 1 oz per gallon of water, per the product label, depending on the target pest. It is only used at 5.1 fl oz per gallon for a 1% emulsion for maximum control and protection against subterranean termite infestation.
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 is very good with treating for wasps and other insects. You will use 1 fl oz per gallon of water. Be sure to spray in the areas that they will come in contact with the insecticide. This can be used every 30 days as needed.
Per the Demon Max product label, you would mix 1/2 oz to 1 oz per gallon of water.
For indoors Apply as a crack-and-crevice or spot application to areas where these pests hide, such as baseboards, corners,storage areas, closets, around water pipes, doors and windows, attics and eaves, behind and under refrigerators, cabinets, sinks, furnaces, and stoves, the underside of shelves, drawers and similar areas.
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.
Demon Max is labeled for milipedes, and will eliminate the ones that are in the area currently. There are a few things that you can do to possibly stop them from coming to the area to begin with. Habitat modification is key to reducing your milipede population. Since they live in and eat organic matter, try to remove as much excess organic matter as possible like piles of weeds, leaves, etc. Over-mulching and overwatering also can create damp environments for many pests, not only millpedes. Avoid overwatering, and use rocks or other materials instead of mulch if possible. Always pick fruit and vegetables,if they are in your area, as soon as they are ripe to prevent millipedes (and other pests) from using them as a food source.
Demon Max will last for 30 days to exterior areas if applied and dried prior to a rainfall. It should be reapplied if it rained heavily or prior to the product drying.
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.
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.
