Demon WP Insecticide - Questions & Answers

Demon WP Insecticide will carpente bees that come in contact with the treated area.

You are able to apply Demon WP any time of year when you see activity or as a preventative treatment as long as the temperature is not at or below freezing when you are treating. Lady bugs are not specifically listed on the label, but Demon WP does treat for very common insects around the structure including spiders, cockroaches, boxelder bugs, fleas, and ants.

Demon WP will kill carpenter bees that land on treated surfaces or try to bore into treated surfaces and while it is known to be some what repellent it will not necessarily repel them from the area.

You cannot use Demon WP in a hose end sprayer. This is a wettable powder that must be mixed and dissolved into water at the rate of 1-2 packets per gallon of water. There is no way to make a hose end sprayer suck up a powder to disperse in the water as these hose end applicators are only designed for liquids. You also cannot dilute it first and then pour it into the hose end bottle as you will not be accurately treating with the right dilution. You will need to use a hand pump sprayer similar to this Chapin Premier Sprayer to apply this type of product for spider control.

Demon WP Insecticide will create a barrier of treatment around and inside your home to treat and prevent Palmetto Bugs. 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.

The date you see on the bottle will be the date it was manufacturered and packaged. If you store the item at room temperature and out of direct sunlight, the shelf will run between 3 and 5 years.

Demon WP is water soluble and is not a flammable product so there is not any issue with using the product around these areas.

Demon WP does not have a strong lingering odor. You can safely spray Demon WP indoors for spiders and centipedes (be sure to read and follow the product label). You should remove all animals from the room during the application and they should not return until the product has had a chance to dry.  You should not spray areas that the tortoises have direct contact with, keep the application to cracks and crevices around the perimeter of the room. Some species of animals can be very sensitive to any kind of chemical and if your tortoises fall into this category we recommend you contact your veterinarian for further advice.

Demon WP is labeled for flea control in outdoor settings and will do a great job killing them when used as directed on the Demon WP product label.

Demon Wp is not labeled to be applied in dishwasher and A/C ducts. It is very important that you read and follow the product label to avoid contaminating sensitive areas. You can use a high quality roach bait gel such as the Advion Roach Bait Gel to treat areas where spraying would not be appropriate (counter tops, cabinets, drawers, around dishwasher, a/c vent). The roaches will consume the bait and then go back to their nesting area and spread the bait which will help eliminate the roaches more quickly than spraying insecticides and IGRs alone. Getting rid of roaches is not a process that only takes only a few hours. Moderate roach infestations can take a few weeks to get rid of and severe infestations can take several months even when using all of the products needed (insecticide, IGR, roach bait) and sanitation is up to par.

Talstar P and Demon WP are both synthetic pyrethroid products and work in a very similar way. The key difference here would be that the Demon WP is a wettable powder and as such it is able to stay on the surface of porous areas allowing insects to come in contact with it a bit better. That being said Demon WP also leaves behind a white powdery residue that is visible on dark surfaces. Talstar P is a concentrated liquid that is odorless, dries clear and is labeled for a huge variety of insects (including roaches) and areas making it a bit more versatile.

Demon Max is made by the same company that makes Demon WP and they both contain the same active ingredient just different formulations.  The main difference is Demon Max can be used as a termiticide to treat and protect homes against termites and can be used for general pests.  Demon WP is more for general insect control inside and outside homes. 

Demon WP is not labeled for indoor flea control.  You would want to use a product such as Precor 2000 Plus Premise Spray. This product is easy to use and is safe to broadcast all over your floor surface. Precor 2000 Plus Premise Spray will kill adult fleas but also stop the reproductive cycle of those flease preventing them from laying more eggs. You would want to keep your baby and all children out of the treatment area until it dries completely. It normally takes a couple of hours to full dry. Once it has dried it is safe for you to bring your baby back into the treated area.

Demon WP is great for all insects, including spiders.  It will do a great job for wolf spiders as well as all other insect control.  You should apply Demon WP once a month for maximum effectiveness. 

Typically you would want to apply 1 gallon per 1000 square feet of yard.  Each gallon would have one scoop of demon.  So, if your yard was 2000 square feet, you would place two scoops of Demon in the hose end sprayer, then fill the hose end sprayer to the 2 gallon mark with water.  This should apply one scoop per gallon of water over 1000 square feet. 

There is no difference between Demon WP and Cynoff WP other than they are made by different manufacturers.  They both have the same active ingredient, cypermethrin, and treat the same pests.  Just like there are different manufacturers of aspirin at the pharmacy, there are different manufacturers of pesticides that basically do the same thing as well.

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.
