Each foil envelope of Demon WP Insecticide in Water-Soluble Packets contains four water-soluble packets of Demon wettable powder (WP). The foil envelope must be opened for use. Because water-soluble packets readily dissolve in the presence of moisture, do not allow them to get wet before adding to the applicator tank. Wear dry gloves when handling the water-soluble packets. Handle with care because excessive handling may cause rupture of the water-soluble packet. Unused water-soluble packets should be stored in the original foil envelope, folded over to minimize exposure to moisture. Demon WP Insecticide in Water-Soluble Packets are intended for dilution with water for applications. For best results, dilution should be achieved if the following steps are taken: 1. Fill applicator tank 1/2 with water. 2. Add desired Demon WP Insecticide in Water-Soluble Packet(s). 3. Allow 1-2 minutes for dissolution of water-soluble packet(s). 4. Agitate, stir or shake applicator tank. 5. Finish filling applicator tank and agitate again before use to ensure satisfactory suspension.
Note: • Upon standing without agitation for more than 1 hr., the applicator tank should be agitated, stirred or shaken again to achieve satisfactory suspension. • Make up only amount of application volume as required. • This product should not be applied with oil.
Tank Mixing Demon WP Insecticide in Water-Soluble Packets may be tank mixed with other currently registered pesticides unless expressly prohibited by the product label.

Excellent product. I have been using Demon WP Insecticide for MANY years mostly for exterior barrier treatment and in and around garages. I was very impressed. I will never forget the first time I used this product. I sprayed a heavy line in front of our 3 car garage which was getting bombarded by all kinds of crawling insects. It created about a 10-12" line on a hot & sunny day and it dried very quickly. I did it a second time thinking it evaporated, again it dried within a few mins. Came home from work the next day and a solid line of dead bugs exactly where I sprayed. Was as if it was an invisible electric fence. At this point I was sold on this and nothing else. I have continued to use it for years without fail. I found it lasts quite a while but depends on how much direct rain the treated surface area gets. Recommend 100%

"It just works" says it all. I have been using Demon WP Insecticide for 10 years. Forget what you read about multiple applications per year. Maybe outside, but inside, unless you wash or vacuum it away, it lasts forever. I haven't used it in 2 years indoors and it's still killing. I thought, after two years, though, another application couldn't hurt. The first time you use it, when you wake up the next morning, you will be in awe of the dead insects in your house. Just do every base board, even in cabinets and closets and every threshhold into your house, garage, carport, etc...threshhold exteriors need to be repeated if exposed to the elements. This stuff is the last word in pest control. Don't waste your money on supermarket and building supply store junk and pest control companies that come out and use this same stuff, and bill you $250.

Demon WP does the best job killing roaches with the fastest knock-down I have ever seen . However, for spiders it doesn't fair so well in my opinion. Only complaint is it leaves a slight stain on wooden floors and baseboards . It keeps killing a long time so re-spraying is only like 4 or 5 times a year . That itself will save you a bundle of money on exterminators.

Demon WP Insecticide powder works wonders for controlling bugs outside, and you don't have to spray chemical's inside your house. Very pleased, been using it for 4 years!

Great product!! I've been using this product for 2 years and living by the ocean, we have our fair share of palmetto bugs, roaches and every crawly bug known to man. Demon WP keeps the house insect-free and considering I have a bug phobia, this means a great deal knowing that there aren't any unwelcomed pests crawling around our home. Anyone having a problem with bugs should try this product...you'll be glad you did!!
No. Demon WP is not labeled for use on any person or animal.
Is Demon WP safe around children and pets?
Demon WP is safe to use around children and pets when mixed and used correctly. With most professional products such as Demon WP, once you mix it with water it is only strong enough to kill small insects. You should always keep children and pets away from where you are treating. Once the product has time to dry which usually only takes 30 minutes, it is safe for children and pets to re-enter the room. Of course you should always keep any pesticide or cleaning product out of reach of children.
Is Demon WP effective against the Hobo spider? We seem to have an epidemic of them in and around our home (and neighborhood). I have killed or "sticky trapped" about two dozen in the last two years. Specifically, will it "deter" them from entering the house?
Yes, Demon WP is one of the most effective insecticides on the market today and is labeled for almost all insects. The "WP" part in Demon WP stands for wettable powder, and wettable powders are what you want to use with spiders. Not only is this product very effective but it is still safe to use inside or outside and also safe if children or pets are present. Place a good, wide, barrier around the perimiter of your home and you will see a huge difference in the number of all insects you see around the home.
Will Demon WP "plug up" regular backpack sprayers - unless they have special "diaphram pump"?
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 refill 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.
