Customer Reviews for Demon WP Insecticide

All you have to do is drop the bag into a sprayer, add water and spray. It works! I use it a couple of times a season by spraying it along the base of the house and along the edges of the windows and door frames.

After using the product, found 3 dead roaches in the garage, 4 on the front porch, along with multiple spiders around house. Would highly recommend.

We have been using this product for years. It keeps out the Boxelder bugs that keep getting in along with Stink bugs and all the other common bugs.

I was a professional exterminator for years. This is the secret product that we used before the general public got their hands on it. It is a Super Product and has a long residual. Well worth your time and money. Super cheep. 10-12 dollars for a package. If you have filthy and dirty kitchen this will help cover your laziness.

I have used Demon WP once a year, in my old house and now in my new house. I live in the middle of Ocala National Forest on 4 acres. It works great for long term protection against roaches, spiders, fleas, ticks, wasps, etc. I only have to spray once a year and it keeps these pests away.

It takes about 4-5 days to start noticing dead bugs but will last for a long time. The other brand that supposedly has the same two main ingredients doesn't work as good. I have several rental properties and the folks at Do My Own Pest Control help me out if I ever have questions too.

Far exceeded my expectations particularly for its ease of use and effectiveness. Asian Beetles, Boxelders, Spiders and Flies are all GONE. Most within a few hours and the rest within a few days. I wish I would have known about this product a long time ago.

I love this product. A small amount goes a long way. Kills everything outside before they can get a chamce to come inside. I have never had to spray inside my house. I would never use another product. I am kinda bugged it only comes in the envelopes now. I really like to purchace the canister.

We have been using this product for at least five years and it does a great job, all the other products advertised are a waste of money.  This lasts us over two or three years as long as you use it correctly, thanks for a great product!

Easy to mix with water and use in a sprayer. Long lasting and highly effective at killing roaches and other bug pests. No residue and easy cleanup. Beats the washed down stuff you can buy at your corner store, hands down.

Product was easy to use and so far since spraying the foundation and 3 feet up the side of the house no scorpions have gotten in. I only gave 4 stars because I do not know how long the protection will last. But 5 stars if I never see another one in the house!

I have always used DEMON WP. Works great and is long lasting. I have told everyone I know to stop wasting money on pest control companies and get their products here. There is nothing the pest control companies use that you cant get from here. In fact, most dont even use the best stuff because they need you as a customer.

Noticed carpenter bees boring in 2x4 frame of my water well shed. Sprayed and found dead bees the next day. Also, had crazy ants running along a trail along the outside slab of my shop which has a roof and open on three sides. Sprayed the trail and floor with Demon (2packs/gal water). Never seen so many dead ants the following days. Used a battery leaf blower to clean the floor.

This product was shipped on time and was as advertised. It effectivly eliminated wood bores in my log cabon. Don Stewart

I have used this product before, (at several times the price) with excellent, long lasting results eliminating American cockroaches. However, be advised that this product is not effective on German cockroaches. For those you need to block off all water sources. Before turning in for the night, towel off the sink/tub basins until completely dry, cover all drains, keep dishwasher tightly closed. They'll move out on their own within a few days.

Was turned on to this product several years ago by a neighbor. Ever since then I have had ZERO problems with cockroaches. It is effective as long as it isn't washed away. For example, in my garage where it doesn't get wet, I only apply it every other year, and still, the only bugs I see out there are dead ones. I recommend this stuff to all of my friends. I'd give it another star, but it doesn't seems to effect crickets.

A few carpenter ants showed up taking their last breath after the application of the Demon WP. ( Actually carpenter ants do not have lungs ) Since then all the areas that I sprayed are clear !!!!! Will be on the lookout to see how long before they start showing for another feeding of the Demon. This is going to be my chemical warfare weapon for this enemy.

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.

I purchased this product last spring due to having ants, spiders and crickets. This product is simply awesome. I have sprayed this in my basement around my home and have not seen a bug in almost almost a year. I sprayed my garage and everything I mean every bug dies from this product. I will never buy anything else as long as this product is available.

This product works well. As many reviews have already stated, so no need to rehash the how's and why's - just know this will work for you. Easy to use, effective, and long-lasting. Even in Central Florida I can get away with one or two treatments a year as an outside barrier. Occasionally [every-other year] will spray key areas inside, but this does a great job of preventing any intrusion into my home at all with the exterior application.

Living in Florida, we have lots of creepy, crawley things. Nothing kills and lasts as long as Demon WP. I usually only have to spray every 6 months. It kills and controls al types of ants, earwigs, palmetto bugs, spiders, no-see-ums and I'm sure other bugs that I've never seen. You just can't beat it. Way cheeper than a contract with an exterminator.

Recently moved into an older house that has been empty for a couple years. Saw and killed several brown recluse. Pest control came and sprayed for $80 and it did nothing. Read the reviews for this and decided to give it a try. Mixed according to directions for spiders and sprayed all along the baseboards inside the house, garage, and along the outside foundation. Opened a few windows and left for a couple hours while the house aired out to let the product dry. Upon returning I found a dead scorpion at my doorstep lying on the line I had sprayed. Absolutely fantastic product and worth every penny.

I mainly have (had) a problem with ants and roaches and probably other things. Demon WP along the base boards really takes care of them. If you see one he is dying. I also use around the foundation. Ant beds (fire ants) I spray directly, they come up and die. Great product, easy to use.

I'm not sure if I did something wrong but I mixed up the "knockdown" method of two packets in a gallon of water and sprayed it all around outside my house, under appliances, along baseboards, etc. Seems to have worked fairly well but I still have a few bugs that make it on the counter-tops and around my Keurig.

I have purchased this in the past and had great results, However this time I bought it along with the Gentrol IGR Concentrate for the small Florida roaches, So far I am not getting much of any results, Not finding dead roaches like I should and they are not dissipating,

I'm very pleased with the results after spraying the house with this. There is always a line of dead bugs along the base of the house the following day and no more bugs inside either. Save money and do it yourself!

I've been using this product for a couple of years now and it really works. I spray around the perimeter of the house and up along the siding about two feet. I also spray the window sills and the door openings. This product has cut down my bug problem by 90%.

I live in a rural area that hosts scorpions that used to make my house their summer home. Since using Deamon on a quarterly program all I see are dead or dying along with any other insect that wanders in. I recommend this product

The best bug killer I've ever used. I hand brown recluse spider bad. The only ones I see now are curled up and dead. Sprayed inside and out before I moved in second house. Same thing spider, roaches, ants all gone. Lasts a very long time like a year indoors. Outside not to sure but things crawled out and died I'd never seen before. But out side bugs don't concern me that much just the ones coming in be sure to spray in weep holes of house and around windows. The packet desolves in water in your sprayer. So you never have to touch it.
