Demon WP Insecticide - Questions & Answers

Demon WP is not a problem to use around pets as long as you apply it according to the label. Once Demon WP is mixed with water it is only strong enough to kill small insects. You would not want to leave the jar of Demon WP open where dogs could get into a large quantity of it. It is always a good idea to keep pets and children out of the area while you are treating. Once the product dries, usually after 30 minutes, it is perfectly fine to allow pets and children back in the area.

Typically you would want to apply 1 gallon per 1000 square feet of yard.  Each gallon would have one scoop of demon.  So, if your yard was 2000 square feet, you would place two scoops of Demon in the hose end sprayer, then fill the hose end sprayer to the 2 gallon mark with water.  This should apply one scoop per gallon of water over 1000 square feet. 

No, Demon WP is not safe to use around fruit trees. You can take a look at our Edible Garden Product page to find a product that is labeled to be used on fruit trees and also labeled for the insect that you are treating for. Please be sure to read the product label before use.

The Demon WP will leave behind a powdery residue on the surface that may need to be wiped off before staining. A better option would be Cyonara 9.7 which will dry clear on the surface and not need to be removed before staining. It will do just as good of a job at controlling bees as the Demon WP as well as other insects.

Demon WP is great for all insects, including spiders.  It will do a great job for wolf spiders as well as all other insect control.  You should apply Demon WP once a month for maximum effectiveness. 

No, Demon WP should be used on or around your garden. If desirable items are sprayed, we would recommend throwing them out.

You want to mix 2 packets Demon WP Insecticide per gallon water for asian beetles.

Demon WP will kill just about any type of spider that actually comes into contact with treated areas. Demon WP will also kill most other insects (the spiders food source) which in turn helps stop new spiders from moving in.

Demon WP does not contain an IGR so you would need to purchase an IGR separately. You can find our full line of Insect Growth Regulators by clicking here: Insect Growth Regulators

Demon should be applied when it is dry and should also be applied when it is not going to rain for about 4 hours or longer if possible.  Once an insecticide has sufficient time to dry, usually at least 2 to 3 hours, it is considered ready for rain.

Tempo Ultra WP and Demon WP are both labeled for various types of roaches. They have two different active ingredients in them, which is the main difference. We would not recommend using just one product to control roaches. A bait gel and IGR (insect growth regulator) should be added to ensure that you are maintaining control of the roaches.

No, Demon WP should be mixed with a gallon of water and applied with at least a one gallon pressurized pump sprayer per the product label instructions. We do carry a pump sprayer that you can purchase for the application.

Yes, Demon WP Insecticide can be tank mixed with an insect growth regulator.  Just be sure you always follow the manufacturer's labeled mixing instructions for each product.  

Demon WP 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 some what 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 is one of the only products actually labeled for leaf cutter ants. The product label recommends treating the mound 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.

You should not apply Demon WP when you are experiencing any rainfall or freezing temperatures per the product label.

Using that much chemical is what you are doing incorrectly. Fleas did not appear in the unit over night in the numbers you are seeing them, so expecting to get rid of them overnight is unreasonable. Demon is not recommended for use indoors for fleas as you can only treat baseboards with the product and not all the areas where they will hide. While the Demon is allowed to be mixed 2 scoops or 2 packets per gallon, using more IGR than what is labeled to be used is only wasting product. You should only be spraying every 2 weeks for fleas with both an approved insecticide for indoor use for fleas and an IGR. Fogging will only kill the adult fleas that are jumping around while the fog is going off. Foggers are only effective while they are active and leave behind no residual and will not penetrate flea eggs. Please review our tutorial on How To Get Rid of Fleas Indoors to effectively, accurately and safely treat for fleas. This will give you the best idea of what to do to get rid of the fleas as quickly as possible. Keep in mind that even using the right products, the right way it can take weeks to months to completely eliminate a flea infestation if its heavy to catch all the life cycles. You can review our video on the bottom of the page for Home Flea Treatment Indoors that shows you the steps you should take as well. Please let us know if you have any other questions.

You can spray once a month indoors with Demon WP. We recommend you use Demon along with a couple of other products, an insect growth regulator to help halt the breeding cycle and a roach bait gel to eliminate roaches in cabinets, drawers and other hidden areas where spraying is not appropriate, to get rid of the roaches for good. Demon does work great but it cannot be sprayed in many of the places roaches hide and that is where the other products come in.

Demon Wp is not labeled as a broadcast spray. It should not pose any damage except for the possibility it can leave a slight white residual on darl surfaces. Apply as a coarse, low pressure treatment to areas where these pests hide, such as baseboards, corners, storage areas, closets, around water pipes, doors and windows, attics and eaves, cabinets, sinks, furnaces, stoves, behind and under refrigerators, the underside of shelves, drawers and similar areas. Pay particular attention to cracks and crevices; also see Outdoor Surface Use.

Demon WP can be used indoors and there are directions on the product label instructing you how to do so. Demon WP may cause a white powdery residue on dark surfaces that some people find unacceptable.

You can use Demon WP Insecticide and Invict Gold or another cockroach bait gel in the same treatment rooms, however you want to avoid spraying on top of bait placements or in areas where you are going to place baits. Your general rule is to SPRAY LOW and BAIT HIGH. To mix the Demon WP, you should use 1-2 packets per gallon of water, so if you were to use less water, you should still use at least 1/2 gallon of water for 1 packet. You could also choose a ready-to-use product instead of a concentrate so that you do not have to worry about mixing correctly. We sell a new product called Dos Flea and Crawling Insect Spray which contains both an insecticide and an IGR for control of roaches and other listed insects. Please see our Roach Treatment Guide for more tips and information.
