    Q
    Can I use Demon WP alongside Invict Gold Cockroach Bait Gel?
    A

    You can use Demon WP Insecticide and Invict Gold or another cockroach bait gel in the same treatment rooms, however you want to avoid spraying on top of bait placements or in areas where you are going to place baits. Your general rule is to SPRAY LOW and BAIT HIGH. To mix the Demon WP, you should use 1-2 packets per gallon of water, so if you were to use less water, you should still use at least 1/2 gallon of water for 1 packet. You could also choose a ready-to-use product instead of a concentrate so that you do not have to worry about mixing correctly. We sell a new product called Dos Flea and Crawling Insect Spray which contains both an insecticide and an IGR for control of roaches and other listed insects. Please see our Roach Treatment Guide for more tips and information.

    Q
    When can I wash my floors after applying Demon WP?
    A

    We generally recommend cleaning surfaces before applying residual insecticides such as Demon WP. If you are scrubbing an area with soap and water or other cleaning products, then you would also be removing the residual insecticide, so you would not clean those areas after spraying unless you also want to remove the insecticide or plan on retreating again soon. Keep in mind that Demon WP should be used indoors only as a spot or crack and crevice spray.

    Q
    What is the best product for stink bugs?
    A
    Stinkbugs can be eliminated with Demon WP. In fact, we offer Demon WP in our stinkbug/overwintering kit because it is so effective. Stinkbugs are not listed on the label of most insecticides yet because they have only started becoming a problem for homeowners and property owners in recent years. Be sure to spray eaves, soffits, window frames, door frames, areas where cables, pipes or wires enter into the structure and any other crack, crevice or gap where insects can harbor. Stinkbugs that are indoors should be vacuumed up. It is also important to seal any holes, cracks, crevices or gaps where the stinkbugs are gaining entry.

    Q
    Which product would successfully eliminate American cockroaches?
    We just moved to Texas, and bought our first home. We have these cockroaches INSIDE our home that fly. We were told they are called American cockroaches, but they look like something out of a childhood nightmare. Please recommend a product that we can purchase to use with a sprayer, that would be most effective for central Texas American cockroaches.
    A
    The best product we have for the larger cockroaches, or American cockroaches, is a product called Demon WP.  Demon WP is a wettable powder that you mix with water in a one gallon sprayer.  Wettable powders are easier for the roaches to pick up on their bodies, and they pack more of a punch which is what you need when treating for larger roaches.  Since the larger roaches come from the outside, you want to concentrate your spray on the outside of the house.  Spray 2 to 3 feet up onto the foundation and 2 to 3 feet out onto the ground.  You can also treat inside the rooms where you have issues.  Demon WP is not only labeled to treat roaches, but almost any other insects you may have a problem with including spiders, ants, silverfish, etc.  You should apply once a month for best results.

    Q
    Should I wear a mask when spraying Demon WP? If so, what strength?
    A
    You do not need to wear a mask when spraying Demon WP unless you are spraying in a small confined area or an area that has poor ventilation. If you find that you will need a mask for the application we recommend using the Comfo Classic Respirator Mask with P100 Cartridges.

    Q
    If a dog eats grass that has dried demon wp will it poison them?
    We sprayed around our foundation yesterday. Sometimes our dog eats grass. If she was to eat grass around the foundation that had dried demon WP, would it poison her?
    A
    The small diluted amount of Demon WP that is left on grass after an application has dried should pose no threat to your dog even if he eats a bit of grass that has been treated.

    Q
    Live in apt. Have been using Advion and boric acid for roaches. Roaches still alive.
    Keep getting straglers about once per month. Could the bait gel be attracting them? Perhaps I should start using spray.
    A
    You should definitely be using an insecticide spray to stop new roaches from moving in. Demon WP is one our most popular roach control sprays. You can also caulk all of the cracks and crevices around the baseboards, door frames, window frames and places where cables pipes and wires enter through the walls to block the passage of roaches from your neighbors apartment into your apartment.

  • Asked by Michael from Naples, Fl
    02/04/2013
    Q
    Can I use Demon WP, Maxforce magnum and Gentrol all at once or should i use them all at different times?
    A
    You can use them all at once.The Maxforce Magnum should be applied by placing one small pea sized dot every 10-12 inches directly into cracks and crevices around counters, sinks, drawers and cabinets. You should use one Gentrol Point Source disc for every 75 sq ft of space. In order to know how many discs you should use you would need to know the square footage of the room (multiply the length of the room by the width of the room) (If you have the Gentrol Liquid you can mix it in the same gallon of water as the Demon and spray them together indoors). Demon WP should be sprayed outdoors around door frames, window frames, in areas where utilities (cables, pipes, wires) enter into the structure, around the bottom of the foundation and other areas where insects are known to harbor. Inside you should apply Demon WP along baseboards, in cracks and crevices,under appliances, around door frames, window frames and in areas where utilities (cables, pipes, wires) enter into the structure.

    Q
    When spraying the Demon for roaches does it normally bring out more roaches than usual?
    It seems as if the sightings are more frequent after using Demon.
    A
    Demon WP is a repellent and it is possible to be detected by the roaches.  However if you are following the instructions on the product label it should not bring out more than usual.  If you are not using a roach bait gel we recommend to use Maxforce FC Magnum. The Maxforce FC Magnum is the newest and fastest-acting roach bait ever by Maxforce. With Maxforce Magnum you get five times the fipronil, plus a new technology called ContactX(TM) which kills roaches by contact as well as ingestion.We also have an application video on Maxforce FC Magnum page to show how and where to apply the bait.

    Q
    I sprayed Demon WP in my kitchen where the roaches are the worst.
    I have taken everything out of cabinets, is it ok to put the plates, food, etc. back in the cabinets once it dries. Or should I wait til it dries then wipe it up and then put it back?
    A
    Once Demon WP is dry, is it okay to put your belongings back into the cabinets. Depending on how thoroughly you sprayed the cabinets and how much residue is left behind - It is up to you if you want to wipe it out as well before replacing your belongings.
