Demon WP Insecticide - Questions & Answers

Yes, Demon WP Insecticide may be used as a crack and crevice treatment for general pest control indoors.  Pets and children should be kept out of the area while the product is being applied and until it has thoroughly dried. 

We would recommend Demon WP for your problem.  Demon WP is a powder you mix with water and apply using a one gallon hand pump sprayer.  Demon WP is excellent for the cracks and holes in the basement and around the apartment because powder sticks to porous surfaces.  It is labeled for inside and outside use, and it is very safe for pets.  Once you have applied the product and allowed it time to dry, usually 30-45 minutes, it is perfectly safe for your pet to re-enter the room or to go outside.  It is also labeled for just about any pest you would have a problem with.  The 1lb container will last for years and will make enough solution to treat every 3 months for years to come. 

Demon WP is a great product for Lady bugs. Unfortunately, if you are dealing with them in your house right now you will only see limited results. Lady bugs move into structures to overwinter. They usually squeeze into wall voids, false ceilings, attics and other areas that are inaccessible to people and insecticides. As the heat kicks on in the house, the lady bugs warm up and start becoming active and emerge from hiding, driving homeowners nuts. Because most folks usually have no idea where the bugs are harboring you can only treat around baseboards, door frames and window frames and hope the insects will emerge where you have sprayed. After they contact the treated areas, it can take several hours for them to die. It is still worth spraying now to get rid of some of the bugs, but you will keep seeing them until spring when they will emerge en masse and leave your home. They do not eat, mate or lay eggs while indoors so need to worry about any damage or future baby lady bugs. This year you can be proactive by stopping these pests before they move in for the winter . You should spray Demon WP outdoors around your door frames, window frames, vents, eaves, around the bottom of your foundation, and any other crack or crevice where an insect could gain entry once a month August-November. We do have an Overwintering kit that includes Demon WP and enough product apply all monthly treatments during August-November.  Please let us know if you have any questions, we are always happy to help.

You can use Demon WP in a backpack sprayer for mosquito control. Demon WP is not labeled for use in a mist blower. If you would like to use a product in a mist blower for mosquito control you can use Talstar P. 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. Demon WP can reapplied every 4 weeks outdoors.

Demon WP is our most popular scorpion product. Demon WP lasts for about 4-6 weeks outdoors and about 12 weeks indoors.You can Demon Wp over the lawn and also use it as a barrier spray for your home to eliminate scorpions before they try to move indoors. You should 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.

These products should not be mixed together. There is no valid reason to mix Demon WP/Cyper WP and Talstar P/Bifen IT together.  Talstar P/Bifen IT is a synthetic pyrethroid and Demom WP/Cyper WP already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.

Demon WP will do a great job getting rid of the brown stink bugs that land on treated surfaces.

We apologize you are having an issue with the Demon WP. We have never had anyone complain that it came out as a muddy color. The powder is usually a darker off white color and when mixed with water the solution is usually an off white creamy color. With many products the colors can vary a bit depending on the source of the raw materials and that may be the case with this product as well. We recommend contacting the manufacturer directly so that they can troubleshoot with you and see what may have happened. They may ask you some questions about the numbers on the envelope so they can see if there was a problem with a certain batch. You can reach Syngenta by calling 866-796-4368.

While the Demon WP is a great insecticide and covers a wide range of insects, it would not be our best recommendation for control of grubs and other insects the moles would feed on. A better option would be Merit Granules which is our top grub and lawn infesting pest control product. Please see the Merit Product Label for usage rates and instructions. Also, keep in mind that while eliminating the food sources of the moles in your lawns may temporarily deter them, it is rare that this method alone will eliminate them from your yard. You almost always must use a true Mole Control Product to completely get rid of your problem.

One of our best products for spider control is Demon WP. Dilute it in a gallon of water and apply as a spray in the cracks, corners & crevices, and the perimeters of the rooms. Also, spray around the exterior as well. Spiders tend to like harboring in boxes or other cluttered areas. Consider the attics, basement, and closets for treatment as well.

You should utilize glueboards to trap spiders and other insects in the kitchen and insecticides such as Demon WP or Cy Kick CS in other parts of the house and also around the exterior of the house for spider/insect control.

One scoop Demon WP is equal to two level tablespoons.

Demon WP is an excellent broad spectrum insecticide that can be used safely and effectively indoors and outdoors for roaches, ants, and most other comon insects. Keep in mind that because the Demon WP is a wettable powder, it will leave behind a white film that can be noticable on darker colored surfaces. If your units have white or light colored molding or baseboards then the residue will not be noticeable. If you are wanting an indoor insecticide that dries completely clear then Suspend or Talstar would be great options. Typically, baits work best for ants since ants are normally foraging for food. Providing them with a bait that they can take back to the colony and share is usually more effective then spraying for ants. Advion Ant Bait gel is a fantstic ant bait that is labeled to kill most ant species. If an ant spray is preferrable, then Suspend SC would be your go to ant spray for indoor control.
