Demon WP Insecticide - Questions & Answers

Demon WP Insecticide is safe for children and pets after it has dried.

It is always a good practice to alternate products with different active ingredients. A great alternative to Demon WP would be something like Suspend SC. Suspend SC is a general insecticide that is labeled for various pests, including roaches, mosquitoes, ticks, fleas, etc. This can be used indoors and outdoors around the perimeter of your home. We would recommend 30 days between applications of different products.

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.

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. 

You can spray once a month indoors with Demon WP. We recommend you use Demon along with a couple of other products, an insect growth regulator to help halt the breeding cycle and a roach bait gel to eliminate roaches in cabinets, drawers and other hidden areas where spraying is not appropriate, to get rid of the roaches for good. Demon does work great but it cannot be sprayed in many of the places roaches hide and that is where the other products come in.

Demon WP is only labeled to be used as a crack and crevice treatment along the baseboards. If you have the option use a pin stream setting on your sprayer, you should get a direct stream and it would not spray on the carpet areas. It is possible it will leave some white residue on the carpet but we have not heard of any clumping. Please let us know if you have any further questions.

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.

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.
