Demon WP Insecticide - Questions & Answers

That is a hard question to answer because both work very well.  However, we do sell the Demon WP in our Roach Control Kits and it does work a little faster and provides a punch for quick knock down.  Sprays alone usually do not work.  You should use this along with a Roach Bait so the roaches have something to take back in the walls and other hiding places that you do can not spray.  Our Roach Control Kits have a very high success rate and incorporates sprays and baits.

Roach Control Information

Demon WP is an excellent product for indoor and outdoor use. However, it does leave a powdery residue because it is a wettable powder.

If you are looking to a general pesticide spray, we would recommend Bifen IT. It is an amazing insecticide that is good for various pests, such as spiders, roaches, mosquitoes, etc. It can be sprayed indoors along the baseboards and cracks and crevices. Outdoors it can be sprayed around the perimeter of your home, on ornamentals and trees as well. This is not labeled for edibles. It is also safe once it is dry and dries clear so your pet will not see it. Mopping or getting where you sprayed wet does not affect the product.

Mix one packet of Demon WP Insecticide  to one gallon of water and make sure it dissolves completely before you begin spraying. This mixture will treat 1,000 sq ft and you will need to re-treat every 14 days (do not treat daily) as needed for flea control.  Most folks find they have to do between 2-4 treatments to get rid of the fleas for good along with the use of an IGR such as Archer IGR. You may want to look over our Flea Treatment Guide for more tips and information.

No, Demon WP will not plug up your sprayer, at least initially.  You definitely have to mix wettable powders very well before applying it.  You should fill the sprayer half way with water, scoop in the proper amount of product or drop in the Demon WP envelope, place the top on the sprayer and shake vigorously, then remove the top and fill the sprayer the rest of the way with water.  The sprayer should work fine but you should only mix what you plan on using that day.  Wettable powders will clog a sprayer when the solution is left in the sprayer overnight or for a long period of time.  The powder will settle, become clumpy at the bottom of the sprayer, and will clog the sprayer when you try to re-use it.  So only mix what you are going to use right then and you should have no problems.

If the tarantulas are sprayed directly with the Demon WP or come in direct contact with the treated area, they will, given enough time, die. Demon WP does not offer an immediate knockdown, but instead a long residual. Spiders in general are harder to kill than other insects because their bodies are higher off the ground and they do not groom their legs(the part of them that actually comes into contact with the insecticide) and therefore take longer to receive a lethal dose of the insecticide. Spraying Demon WP will also help to get rid of the insects that spiders feed on and that will help to stop new spiders from moving in. Indoors, spray around all baseboards, door frames, window frames, under appliances, in closets and storage rooms and in areas where utilities enter into the structure. Outdoors you should spray around the bottom of the foundation, on the ground adjacent to the foundation, door frames, window frames and places where the utilities enter into the structure.

Demon WP is not a problem to use around pets as long as you apply it according to the product label. Once Demon WP is mixed with water, it is only strong enough to kill small insects. You would not want to leave the jar of Demon WP open where dogs could get into a large quantity of it. It is always a good idea to keep pets and children out of the area while you are treating. Once the product dries, usually after 30 minutes, it is perfectly fine to allow pets and children back in the area. However, all pesticides are very dangerous to fish and aquatic life. You would not want to use Demon WP or any other pesticide near a body of water. 50 yards away is a good distance, but if the land sloped down towards the pond, then there may be a concern. If it does not, it should not be a problem to treat around your home that is 50 yards away from the pond.

Demon WP Insecticide  is labeled for German roaches however will only kill roaches that come into contact with the treated area and does not have any transfer qualities which is important in eliminating an active roach infestation. This is not a contact kill and take 1-3 weeks to kill the roaches that have contacted the treated areas.

The best treatment for German Roaches as they reproduce quickly and in large numbers would be to use a combination of products along with diligent repeat treatments every 14 days.

While Demon WP can be used on sandy soils for fleas, it should not be used alone.  We would recommend adding an IGR such as Archer or Nyguard along with it.  This will help prevent young flease from maturing into reproducing adults.  Wondercide Flea & Tick Control Pets & Home - Lemongrass can actually be used on the kittens regardless of age.  It is all natural and non toxic.  If this is an indoor barn, then we would recommend using a product labeled for this use such as the Wondercide or Onslaught Insecticide.

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 that will not kill the ants around your home on contact like Demon WP will, but a product that they will take back to the colony and kill the queen and other ants at the source.  Our most popular product for this is Termidor SC.  Or, you can use ant baits that the ants will eat and take back to the colony.  Otherwise, you will be battling the ant colony all summer long.

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.
