    Q
    Can Demon WP be used in the kitchen?
    I would like to spray inside my kitchen cabinets - where plates, cups, sliverware, etc are stored. Is this okay?
    A

    Demon WP can be applied indoors in kitchens using a hand pump sprayer, but is not labeled to be used in cabinets at all. Apply directly into cracks and crevices around the door frames, window frames, places where utilities (cables, pipes and wires) enter into the structure and around the baseboards…

    Q
    After how long is Demon WP rainproof? And how soon after rain can I apply?
    A

    Ideally, you should have at least 24 hours without rain both before and after your insecticide applications. Rain and other weathering will reduce the residual of your insecticides, so it is best to wait to apply if you are expecting heavy rainfall. You want to be sure that your application at least…

    Q
    Is Demon WP effective against the Hobo spider?
    We seem to have an epidemic of them in and around our home (and neighborhood). I have killed or "sticky trapped" about two dozen in the last two years. Specifically, will it "deter" them from entering the house?
    A

    Yes, Demon WP is one of the most effective insecticides on the market today and is labeled for almost all insects.  The "WP" part in Demon WP stands for wettable powder, and wettable powders are what you want to use with spiders.  Not only is this product very effective but it is still saf…

    Q
    Where to apply Demon WP Indoors?
    What is the best way to use the Demon WP spray indoors? Is a concentrated stream where the baseboard and carpet meet better or is a wider spray area? Also, if it gets on to wood furniture will it deteriorate the finish? Thanks in advance.
    A

    Demon WP should be applied to cracks and crevices, underneath appliances, and in wall voids under sinks and behind toilets where pipes go into the walls.  Demon WP should be applied where bugs hide.  It really does not good to just apply all over baseboards or carpet.  It is better to…

    Will Demon WP work on all types of ants?
    I have sugar, red and carpenter ants. Will Demon WP get rid of all of them?

    Demon WP will kill just about any insect, including all types of ants.  However, Demon WP will only kill the ants that walk over where you treat around your home.  It will not take care of the queen and other ants back where the colony is.  The key to ant control is to use a product t…

    Q
    I am finding scorpions in my kitchen sink. Spray Demon in drain?
    Where do the scorpions get into sink. If I spray demon in drain will it effect my septic system?
    A

    We do not recommend spraying Demon Wp into your sink drain. It is very unlikely that the scorpions are actually coming up the drain. Most drains have a P trap at the bottom of the pipe that stays filled with water. This P trap stops bad odors from coming up the pipe and it also stops insects and oth…

    Can Demon WP kill wasps?
    I hate wasps and want to spray demon on my lawn and around the house and in high corners where wasp or hornet nests might form ... will this work or should I try something stronger ( any suggestions will help .)

    Demon WP is one of the strongest insecticides on the market and will work well for wasp control but it will leave a white powdery residue on the lawn and on other dark surfaces. If that is a problem you can use Demand CS which is strong like Demon WP but dries clear. You should note that neither of …
