    Q
    How much Demon WP should I use in a one galllon pump sprayer to kill stink bugs?
    We just purchased your Demon WP to kill stink bugs, but this bug isn't listed on the label instructions. Should we use one packet or two packets in our one gallon sprayer? Our house is covered with these awful bugs.
    A
    For a quicker knock down, you should use two packets per gallon of water for your first application.  After the first application, you can use one packet per gallon of water for your follow up applications.  As soon as the weather turns cold for good, you should not see the stink bugs anymore.

    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 other animals from coming up the pipe. Unless your pipes are damaged, the scorpions are most likely coming in from a nearby window fame or around cables, pipes or wires that enter through the structure and they are falling in to the sink. You should spray every crack and crevice around window frames, door frames and places where cables, pipes and wires enter into the structure. You should also spray outdoors around your foundation and around window frames, door frames and places where cables, pipes and wires enter into the structure.

    Non-insecticide methods for scorpion control are:

    Harborage Removal- Harborage removal is key to scorpion control and will greatly reduce the numbers of scorpions in the area surrounding the structure, making it far less likely that they will enter. Harborage removal includes eliminating piles of lumber, bricks, and other stacked items that create clusters of tight spaces, elimination of vegetation and other heavy ground coverings near homes and buildings, trimming back tree and shrub limbs from walls and roof, and keeping gutters clear of leaves and other debris.

    Exclusion- Scorpions and other pests can be kept out of structures to a large degree by installing tight-fitting screens, weatherstripping around doors and windows, and caulking cracks and crevices.

    Q
    What product do I use to kill spiders?
    A

    Demon WP is a great choice for spider control. Demon WP is a wettable powder that is diluted in water, and then sprayed around door frames, window frames, in areas where utilities (cables, pipes, wires) enter into a structure, around the bottom of the foundation and other area where insects are known to harbor.  Demon WP can leave a white powdery residue on dark surfaces. If the powdery residue is a concern, you can choose a micro-encapsulated product such as Onslaught Fast Cap Spider and Scorpion.

    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. In kitchens you can also apply behind the fridge, stove, and under the dishwasher.

    Q
    Why should you not leave Demon mixed with water in proper storage? Will it retain stength?
    I see the answer posted not to leave Demon mixed up with water if you have left over for example, I wold like to know why. safety? strength?
    A
    Demon WP should be used with 24 hours after it has been diluted with water. There are a couple of reasons for this 1. insecticides will start to degrade if they are left standing in water because of the acid in water 2. Demon WP never truly dissolves in water and it will separate and clog your sprayer. You should also note that leaving liquids standing in your sprayer will void the warranty of most sprayers as most chemicals and even water will corrode the tank, seals and other sprayer parts when sprayer is not properly rinsed between uses.

    Q
    What is the most effective pesticide for hobo or brown recluse spiders?
    A
    Demon WP and Cy-Kick CS are our most popular products for those hard to kill insects such as spiders. Both of these products will also kill the other insects in and around your home which will help prevent new spiders from moving in since they will not be able to find a food source. Both of these products will give you a pretty fast knockdown and a long lasting residual.

    Q
    Does Demon WP harm plants?

    Demon WP is labeled to spray on plants and lawns and should not cause any damage to them. That being said we still recommend that you test a one plant or a small area before broadcasting the spray as some plants can be sensitive.

    Q
    Is Demon WP effective against mosquitoes?
    A
    Demon WP is labeled for mosquitoes. According to the Demon WP product label: For mosquito control, apply as a general structural perimeter spray to landscape plantings, turf, and building foundations to control mosquitoes. Yards or other frequented areas enclosed by landscaping can benefit from the creation of a mosquito barrier to reduce invading mosquitoes by the treatment of perimeter vegetation. For best results, apply Demon WP at recommended rates in 2-5 gallons of water per 1,000 sq. ft. Higher volumes applied result in better coverage and, as a rule, will improve control.

    Q
    Will Demon wp kill roaches and their eggs
    A
    Demon WP will kill roaches but it will not kill roach eggs. Insecticides will only kill insects after they have hatched from the eggs. Insecticides cannot penetrate the egg shells. We would recommend using an Insect Growth Regulator such as Gentrol IGR along with the Demon WP as it can make some of the eggs non-viable and it will halt the reproduction of the juvenile roaches.

    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.

    Q
    Is it safe for my animals to graze where we treated with Demon WP? Chickens cows goats?
    A
    Demon WP should NOT be applied to areas where animals will be grazing. We recommend contacting your Local Cooperative Extension Office to find out what product would be safe and effective for you to use in your area. Once you have been given a recommendation, we can try to help you locate the product for shipment.

    Q
    Does Demon WP kill bed bugs or is it active against them or what mix with it is for best results?
    A
    Demon WP is not labeled to treat for bed bugs, therefore we cannot recommend using it.  What we do recommend is our Bed Bug Kits.  They have a very high success rate and have all of the same professional products that a company would use if you hired one.  Our kits also come with full instructions on how to apply the products in the kit. Of course, we are always here to help you with any questions as well.

    Q
    Can Demon WP be washed away by rain or regular sprinkler use
    A
    Once the Demon WP has had a chance to dry it is going to be rain fast for several weeks. You should plan to re-apply Demon WP once a month outdoors for best insect control.

    Q
    Will Demon WP kill brown recluse spiders?
    A
    Demon WP does a fantastic job killing just about any spider that comes into contact with treated surfaces. Demon WP will also kill most other insects which will eliminate the spiders food source and make your home and property a less favorable hunting ground. Demon WP does not offer an instant knockdown and it can take several hours to a day for spiders to die after they come into contact with the dry residual. Please take a few minutes to read our article Brown Recluse Spider Control to learn how to make your home less favorable to this pest.

    Q
    I have the one pound can of Demon WP. How many scoops to 1 Gallon of water?
    A
    Demon WP can be mixed at a rate of one level scoop per gallon of water, or two level scoops per gallon of water.  Most pest problems require only one scoop per gallon.  If you are treating for bees, wasps, scorpions, roaches, or carpenter ants you would use two scoops per gallon.
