    Q
    Will Demon WP Insecticide kill Ceratopogonidae- biting midge?
    Will this product kill noseeums- Ceratopogonidae- biting midge--- Desperate!!!! They are in our yard-- we do live in the woods-- I also have children and pets-- how long should they stay out of the yard if the product does in fact kill these insects.
    A

    Demon WP will kill Midges that come in contact with it. It cannot be applied as a broadcast, however. Talstar P would be a great product for you. Spraying a product such as Talstar P on window screens, doors, bushes, and plants around your home can act as midge repellant to keep midges away. Citronella candles or oils can act as a midge repellant, but they aren’t as effective when used alone. Talstar P is safe for children and pets after dried.

    Q
    Will Demon WP kill sugar ants?
    A

    Demon WP Insecticide will kill ants that come in contact with it, but it will not eradicate them.  

    Phantom would be a good choice for ant control. Phantom should be applied around baseboards, door frames, window frames and places where utilities (cables, pipes and wires) enter through the wall as these are the most likely places for the ants to enter/exit. You can also treat all around the foundation of your home and the exterior window frames, door frames and places where utilities enter to stop the ants from gaining access in the first place. Phantom is a non-repellent insecticide that has a delayed reaction which allows ants time to get back to the colony and spread the product. In essence, the ants will not be able to tell that the product is in place and they will pick it up on the fine hairs all over their body and inadvertently carry it back to the colony where over a course of a few days it will knock out the entire colony. Phantom works really well because you don't have to worry about whether the ants will all take the bait, they just need to walk over the treated areas. Phantom comes in two formulations, concentrated liquid and aerosol for your convenience. Be sure to keep your pets out of the area while you are treating and they can safely return to the treated areas as soon as they are dry, usually 1-2 hours.

    Please see our Ant Treatment Guide for more information.

    Can I spray my red oak tree with Demon WP to control ants? Will Demon WP harm my tree?
    A

    Demon WP could be applied to ornamental trees, however, it may leave a white powdery residue on the leaves. Temprid SC could be applied to the ornamentals for ants and many other common pests and would dry clear.

    When used as directed on the product label, the small diluted amount of Demon WP that is left on grass after an application has dried should pose no threat to rabbits even if he/she eats a bit of grass that has been treated.

    Q
    Can I spray demon on queen palm trees for a ghost ant issue?
    A

    Demon WP Insecticide is labeled to be used on lawns, ornamental trees and shrubs and it is labeld to treat ants, but it can leave a white powdery residue behind, and it will only kill the ants that come into direct contact with it.  You may wish to use some ant bait in addition, applied around the base of the tree, so that they will consume it and share it with the entire colony.

    Q
    I've been using Demon WP for general pest control. Is there something you'd recommend over that?
    A

    Recommendations are based on what you are treating for. Demon WP is a very good general purpose insecticide for pests like spiders, roaches, etc. Keep in mind that it can leave a white residue behind on some surfaces. 

    Another good option for general pest control would be Cyzmic CS. This is a liquid concentrate that is mixed with water. It will go on clear and dry clear as well. The residual indoors is 90 days and 30 days outdoors.

    Q
    Is it okay to spray Demon WP on Limestone blocks skirting around your house?
    Does it break down the material of the Limestone block
    A

    Demon WP should not damage limestone or any rock or other surface. Demon WP does leave a visible white residue on darker surfaces, but that should not leave any permanent stain. We recommend testing a small area first if you are concerned about this residue.

    Q
    A day after your house is sprayed with Demon WP Insecticide, what if a child drops food on the floor and then eats it? Is it poisonous to them?
    A

    We do not recommend that your child eat the food that fell into the treated crevice that was recently treated with Demon WP Insecticide. Have the product container, label or Safety Data Sheet with you when calling Syngenta (800-888-8372), a poison contol center or doctor, or going for treatment if needed.

    Q
    How long does Demon WP take to kill a fly if it perched on a sprayed surface?
    if a fly perch on a sprayed surface that has been treated or sprayed with demon wp,how long will it take for the fly to die?
    A

    Depending on the size and health of the fly and the amount of Demon WP it contacts, it generally would take anywhere from a few minutes to several hours for an insect like a fly to die after contacting an area treated with Demon WP. For a very quick kill for flying insects, we recommend Maxforce Fly Spot Bait or Alpine Pressurized Fly Bait.

    Q
    Can Demon WP kill red flour beetles?
    Bought a fairly new rv, great condition. Seem to have a red flour beetle battle on my hands. No signs of food/grain, even in floor ducts. Cleaned, vacuumed every cabinet, floor, surface, nook, cranny and duct. They come back a day later to no avail. Rv is in new location so local infestation/infiltration not relevant. Is it possible they are in the interior paneling?? How do I eradicate these buggers without ripping my rv apart? Help!
    A

    Demon WP is not labeled to control pantry pests, although it would likely kill any that contacted it. For the best control of a stored product pest such as the red flour beetle, it is really essential to keep looking for and to locate that initial source to get full control of the infestation. You can then vacuum and clean infested areas, treat cracks and crevices with a residual insecticide, and use traps for the adult insects. Gentrol Complete is a great spray to use since it includes both insecticide and Insect Growth Regulator (IGR) in one product. You can use GreenWay Pantry Patrol Traps for a pheromone trap.

    Q
    Flea infestation retreatment
    We have a really bad flea infestation in our home. So much so, we have moved out temporarily. How often should I reapply Demon WP? I have heard multiple answers...anywhere from 3-4 days to 4weeks. Flea cycle is 7-10 days. Please advise. We would like to move back home ASAP. Thank you.
    A

    Demon WP Insecticide cannot be used inside the home for fleas, only outdoors as directed on the prouct label.   Fleas treatments with approved products are generally done every 2 weeks with lots of vacuuming in between.

    We would recommend our Indoor Flea Kit. You can see the kit by clicking on the link here.

    Here is a great video on how to use our Indoor Kit here.
