  • Asked by Jessica from Rockford Illinois

    Q
    Can you use Demon WP in the house on the walls I have seen a few roaches?
    Freaking out and I can't handle bugs so I want to go threw the hole house and spray every room is this stuff safe to use like this
    A
    Demon WP can be used inside as directed on the product label.  Insecticides alone will not eliminate an infestation though.  You will need to use it in conjunction with a high quality roach bait gel and an insect growth regulator as roaches like to hide and may not readily come into contact with treated surfaces. You can find both DemonWP, a roach bait gel and an IGR sold together in our Roach Control Kits. The roach bait gel should be placed directly into cracks and crevices around counters, sinks, drawers and cabinets. This will make the gel available to the roaches and inaccessible to your pets and children. The Gentrol Point Source do not actually contain any insecticides, just an insect juvenile growth hormone mimic. These discs can also be placed out of reach of children and animals and are readily used in sensitive locations such as hospitals and day cares everyday. Severe infestations may take several months to eliminate no matter what products you use. Sanitation will be a key factor in eliminating the roaches. Please take a few minutes to read the hints and tips in our German Cockroach article  to learn more about eliminating this pest.

  • Asked by Brad from Lexington, Tn
    02/26/2015
    Q
    I want a residual product for brown recluse. Would the Demon WP or the Onslaught Fast cap work better?
    Also using glue traps.
    A
    Demon WP and Onslaught FastCap are both labeled for spiders. Demon WP does leave a white residue and once it gets washed off, it is no longer working. Onslaught FastCap will dry clear and leave a longer residual since once it is dry, it stays. The only problem with using any type of insecticide with spiders, is that they need to actually walk through it in order for it to kill them. You will need to spray the areas where they frequent, around doorways, corners of walls, etc.

    03/05/2015
    Q
    Is Demon WP safe for pet snakes after it dries?
    Can you put their enclosures near application areas after it dries?
    A
    When used as directed Demon WP would be safe.  Demon WP should only be applied to cracks and crevices, along baseboards etc.  Just putting the enclosure near these areas would not pose harm to the snake.  Pets should be out of the treatment area until dry.

  • Asked by Christopher from Las Vegas
    03/26/2015
    Q
    Is there a benefit to mixing Demon WP with Onslaught Spider and Scorpion?
    Would it be better to alternate between Demon WP and Onslaught Spider and Scorpion or to mix them and spray together to control bark scorpions?
    A
    It is not necessary to mix two insecticides together. What you could do to ensure that the product works faster is use ExciteR. It can be mixed with either Demon WP or Onslaught FastCap Spider and Scorpion Insecticide. ExciteR will provide a quicker knockdown when mixed with an insecticide. If used alone, the residual is not as long.

  • Asked by Krystina from Caldwell, Texas
    04/26/2015
    Q
    I have been using Demon WP for years and have gotten it on my hands, clothes, and possibly inhaled.
    I have been using DemonWP for several years. I use it about 1-2 times per year. I never used gloves while spraying it and I tried not to inhale when I was spraying it. Afterward I would properly store it, wash out the spray bottle, wash off my hands, arms and any other exposed skin and change clothes. Am I in any danger for not using gloves? Or have any reason to be concerned of any longterm effects of the product touching my skin?
    A
    The product label for Demon WP recommends contacting a doctor or poison control center as soon as possible if the product is either inhaled or gotten on the skin.  Please contact a doctor or poison control for more information as to what the possible effects may be.

  • Asked by Phoebe from Belton,tx
    05/10/2015
    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 has time to dry before rain or other precipitation, usually about an hour.
