Customer Reviews for Demon WP Insecticide

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.

Demon WP insecticide is very easy to use and very effective. The packets dissolve easily. Our home was constantly under attack by spiders that would find their way inside before we tried Demon WP. A perimeter spray keeps them at bay for months at a time.

This is by far the very best pest control product I've ever used. I bought my home last year and found that it was a haven for spiders. I am absolutely phobic about them. After using Demon WP I have not seen even one. I spray my home inside and out and plan to do it again before spring sets in. You will not be disappointed with this product.

I work maintenance at a SouthWest Coastal Florida retirement community. I was introduced to Demon WP a few years ago and gave it a try. There was immediate and lasting results. We no longer have ants, palmettos, roaches, etc. wreaking havoc. It is also works wonders on pesky carpenter bees when sprayed directly into the nest. Great product.

This is some good good quality stuff right here. I own a lake house and we have spiders, centipedes, wasps, you name it we have it.  Well I used it for the first time and I had my doubts. After about a week later after spraying the house I noticed no cob webs were formed on house and there was literally bugs dead where I sprayed just laying there.  Now for wasps, I have red wasps bad and I sprayed nest at night and they're still Alive so it don't work too well on wasps.  It leaves a white residue where you spray on dark surfaces but if it keeps the spiders away and me from being bit I don't care, I can deal with the white residue. Best product I used so far and it's my favorite now!

This product works! I bought this along with the 1 gal Chapin sprayer for doing home perimeter spray treatment. I sprayed the perimeter and garage and door entrance ways just like you see in the "how to" video at the website. I did this treatment because warm weather is coming, and I always get spiders coming in. Not any more! Well, they still do get in, but they only make it a couple of inches before they drop dead! Just a couple of days after treatment, I checked my back door where they like to sneak in, and found several large carcasses all shriveled up! I highly recommend this product.

I have used the Demon spray many years ago and had moved out of my home into a senior citizen retirement place and and they provided the spray and had someone to come in and spray a squirt or two of their own spray. It did not do a good job. I moved out and bought my own place and decided to do my own "bug spray" and went back to the "Demon WP " and boy, am I happy I did. I could see the results overnight, inside and out. It even took care of ants in the yard. Thanks for the Demon being available to me. Bob Jarrell, Cocoa, FL

I used the Demon WP for ticks in my yard. After the first day I noticed different bugs outside dead. Cockroaches, etc. I didn't realize I had them. Good stuff and I recommend it.

We have used this product before. It helps control the cockroach population. Also saves a little money doing it ourselves.

Good Stuff. Easy to mix, easy to spray and really seems to kill the buggies.  Next application in three months will give me a better handle on the product!

This is the best product on the market for home pest control. Forget all the bottles of spray junk at your home center. My mother in Florida told me about this product years ago. Just ordered my supply and waiting for our record rains to end so I can apply it to my home and keep all our little friends OUTSIDE!!!

I bought a few of the little pre measured out disolvable packages last year and it worked great. This year I bought the bigger container so I can save a lil bit of money in the long run.

I have been using Demon for several years. I live in Florida and only find the need to use it once a year. It's by far the best stuff I have used in 30 years of self exterminating.  It's easy to use just drop the packet in the water.

I used the product last week; as usual, extraordinary results.  Saw what I believe to be termites, mixed the packets "double-strength". My husband sprayed the 3 areas and like magic, dead termites. My brother and his family were visiting from out of town during this time. When he got home, he called me for the information to order the product for his businesses and for his home. Thanks!!!!

My boss recommended this to me because he uses it in his airplane hangar. I used it around the entire exterior of my home and was shocked by the amount of dead bugs there were the very next day. I highly recommend this product. I won't be using it inside because of the warnings, but I have not needed to spray inside at all.

I received the product as advertised. I've used Demon for many years and like the results.

Demon packet is about $5 and it will keep your house roach free for more than a year. Spray yourself and you know what and where .

I used 2 packets per gallon to make a potent mix. I used it in the house, garage, and outside along the house. Most of the critters we usually see around the house are gone. It's only been about a month so I cannot comment on how long the treatment remains effective, but because it worked as well as it did on the initial application, I will continue to use this product.

This product worked like it said it would. I have been fighting ants in my home for years. Even the professional exterminators could not get rid of them. They would always show up in a different location, including my bathroom ceiling. Since using this product inside and outside along the foundation I have had NO bugs except for the dead ones for the first few days.

I have found the Demon WP to be an excellent all around pest control. You still need speciality sprays for fruit trees and vegetables, but it pretty much does the job on everything else.

I have used Demon WP for several years and since then have recommended it to all my family and friends. It is the most dependable insecticide that's on the market. It takes care of all those little pests. Thanks for such a wonderful product.

Demon WP packets are convenient. Use as much as you need and the remaining power doesn't collect moisture and clumps. This is the same product professional applicators use and has a higher concentration of insecticide than over the counter all-purpose bug-kill products. Although it can be used inside and outside, exterior use which is susceptible to rain, will have a shorter effective time. Once dry, which is almost immediately, it is safe for pets. If you are going to spray your lawn or garden, you might want to purchase similar products which come in larger quantities.

Moved from upper Midwest to Houston to a brick and veneer ranch house and a wood-sided garage. The many ants and roaches and other pests were everywhere every night (and day) even with a contract pest control service. After 5 years a friend recommended Demon WP and for 15 years in Houston and now 13 in Colorado, a once every 3 to 6 months of doing our own pest control treatment with Demon WP has almost made us forget that there are any pests around us. We use it freely outside around the house, and spray very little inside in corners and doorways, enough to discourage the critters. We are glad Demon WP is still available.

I am so impressed with the power of this product that I have told everyone I know about it. We had a problem with the large dark roaches outside until I sprayed. The next day all that was left was dead bugs of all kinds. We haven't had the first roach in two weeks.
