    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.

    Q
    Can I apply Demon to the ground after it rains?
    A

    The ground should be dry before you apply Demon WP. If you apply Demon WP to a wet surface it will not have the opprotunity to bond to the surface and could potentially wash away.

    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 are…

    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.

    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 crevi…

    Will Demon WP stain my Pergo Laminate floors?

    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…

    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
    How much Demon WP do I use in a hose-end sprayer?
    We have a hose end sprayer with 1 oz to 8 oz on the dial and it sprays 4 gallons of water per minute. The bottle is 32 oz, how many demon WP packets do we put in the jar to kill spiders?
    A

    You cannot use Demon WP in a hose end sprayer. This is a wettable powder that must be mixed and dissolved into water at the rate of 1-2 packets per gallon of water. There is no way to make a hose end sprayer suck up a powder to disperse in the water as these hose end applicators are only designed fo…
