  • Asked by Duke from San Diego, Ca

    Q
    What happens to insecticide after mixed 24 hours
    I read one of your Q&A that the insecticide should be used w/i 24 hours of mixing. I put a packet in a gallon container, mix & then fill a smaller sprayer and spray my apt as needed. It's been sitting around for over a day. Will it still be effective? Thank you
    A
    Using Diluted Demon Wp after it has been mixed 24 hours would not be advised. The reason being is that the active ingredient will start to break down and cause the solution to become less effective.

  • Asked by Louise from Houston Tx
    03/29/2013
    Q
    If I wash off the visible white residue when sprayed inside, is any Demon left?
    I don't want to see the white residue and I don't want my family and friends to see it either since many are concerned about chemicals. Plus I don't want to have to explain why it is there.
    A
    If you wipe off the white residue you will be wiping off the product as well. If the residue is a problem for you consider using another product that dries clear such as Talstar P or Demand CS.

    Q
    Will demon hurt chickens that eat the dead bugs or effect the egg safety?
    Sprayed outside 3 days ago. Kept hens up until today, but they immediately went for the dead bugs when they were let out. Will they be ok? Is it safe to eat the eggs or is there a "detox" period where we should discard the eggs?
    A
    The amount of insecticide on the surfaces is so minute that its only toxic to something the size of an insect. Even if the chickens were to eat many of the dead bugs, they would not be ingesting enough poison to harm them or the eggs.

    07/09/2011
    Q
    Can I use insecticide granules in my crawlspace?
    I have an ant, earwig, and spider issue in my new house. I have sprayed around the yard, but they still seem to be getting in. I would assume that the only other place is under the house in the crawlspace. If I were to retreat the yard with granular insecticide, could I also use it in the crawlspace for added protection? If so, which would be the best kind?
    A
    You would not want to use granules under the crawl space of the house.  The reason being is granules require moisture, either from watering or rain, to release the insecticide that kills the insects.  You should always water in the granules after application especially if you are in an area with little rain and moisture.  This may be why you are not getting good results already in the yard.  Since rain will not make it in the crawl space, or at least it should not be, granules are not good for under the house.  In addition to applying granules in the yard and watering them in, you should apply a liquid insecticide, specifically a wettable powder around the perimeter of the house and underneath the house.  Wettable powders are easier for spiders and other insects to get on their bodies typically and are faster acting.  Our most popular wettable powder product is Demon WP and it can be applied using a hand pump sprayer.

  • Asked by Pattie from Austin, Tx
    10/21/2014
    Q
    I sprayed Demon around base boards yesterday and this morning my 8 year old cat
    has vomited about 3-4 times today including tonight at 9:00pm. He is hiding and does not want to sleep on the bed with me which is his practice. He may have walked on wet Demon. What is antidote if he has Demon over exposure?
    A

    We would recommend contacting your veterinarian as soon as possible. They would better be able to give you advice on your cat.

    We do recommend keeping your animals out of any area that was sprayed until Demon WP and any other product is completely dry.

    Q
    Will Demon WP kill millipedes?
    A

    Yes, Demon WP can be used to control millipedes and dozens of other common crawling and flying pests. Be sure to check for ways to reduce moisture buildup in the environment to create an environment less favorable for these insects, such as pulling back groundcover and trimming plants near the foundation of structures.

  • Asked by Diane from Hortense Ga
    08/22/2014
    Q
    After I have sprayed an insecticide how long should I wait before I can put out a roach bait?
    We've already used raid max spray to no avail.now we want to use a roach bait. Do we need to wait a few weeks for the spray to dissapait or can we use a bait now??
    A

    When treating for roaches, we recommend using a bait, a liquid insecticide and an insect growth regulator (IGR). You are able to treat with all 3 of these products at the same time, just not on top of each other. For instance, our Roach Control Kit # 2 has all 3.

    The Demon WP is for crack and crevice treatment around baseboards. Dilute 1 packet per gallon of water in a pump sprayer and apply in cracks and crevices where pests are seen, may harbor, or may enter the structure (corners, baseboards, and under and behind appliances) Do not spray on top of baits where bait will be used.

    Gentrol Point Source Stations (IGR) - this is insect "birth control". These packs contain  Hydroprene, which halts population growth by keeping younger stages of roaches from developing into breeding adults therefore, reducing the population.  These packs last 90 days and are to placed in areas where roach activity has been observed ( cabinets, closets, pantries, drawers, refuse areas, electrical boxes, equipment, and false ceilings)
    Invict Roach Bait Gel - Apply bait in small spots about ¼” in diameter. For most infestations, applications should range from 10 to 20 spots per 100 square feet. Smaller, more frequent spots are better than occasional large spots. Pay particular attention to cracks which lead into void areas, and specifically look for warm, moist areas. Insert the syringe tip directly into the crack and apply about 0.5g (pea size) amount of bait.
    ** You do not place bait on top of where you have sprayed the Demon WP ***
    All 3 of the products are meant to be used at the same time for effective treatment.

  • Asked by Barbara from Tolar Texas
    05/22/2012
    Q
    Can Demon WP be applied to carpet for the treatment of fleas?
    I have used this product on the baseboards and all the exterior of my home but still have a flea problem.
    A
    Demon WP cannot be applied to carpet for flea control indoors. According to the Demon WP product label Demon WP can only be used outdoors for flea control. When using Demon WP outdoors for flea control it is important that you apply the product to places where the fleas develop such as pet resting areas and moist shady spots and not just on the exterior of the structure. We recommend using Ultracide for indoor flea control. It is our recommendation and industry standard that you vacuum immediately before the application of Ultracide and every day or every other day after the application for the next two weeks. Vacuums can physically remove a decent percentage of flea eggs that are in the carpet, along with much of the organic crud that the flea larvae feed on. At the end of the 2 week treatment period you may be required to do a follow up treatment of Ultracide to get rid of any stragglers.

  • Asked by Maayan from Las Vegas
    06/25/2015
    Q
    Can Demon WP be mixed with Suspend SC?
    A
    Demon WP and Suspend SC should NOT be mixed together. There is no valid reason to mix Demon WP and Suspend SC together.  Suspend SC is a synthetic pyrethroid and Demon WP already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.

    Q
    Does Demon WP wash off the outside of a house in the rain?
    We are trying to fight stink bugs.
    A
    Demon WP typically leaves a 30 day residual even if it rains. The places on your house where the product is protected from direct rain contact like against the house that may be somewhat sheltered by the roof line, will last longer than other places.

    Q
    Will Demon WP stain my Pergo Laminate floors?
    A
    Demon will not stain any type of material.  However, since Demon is a powder, after you mix it with water and apply it, there may be a white residue that is left after it dries.  You typically will only see this if you have dark colored flooring and dark baseboards.  The residue can be wiped with a wet, white paper towel very easily.

    Q
    Can Demon WP Insecticide be used any time of year outdoors, or is it best to wait until you see pests?
    Also, will it work on lady bugs?

    You are able to apply Demon WP any time of year when you see activity or as a preventative treatment as long as the temperature is not at or below freezing when you are treating. Lady bugs are not specifically listed on the label, but Demon WP does treat for very common insects around the structure including spiders, cockroaches, boxelder bugs, fleas, and ants.
