Great stuff! Works Fast!
fantastic, safe spray that has many uses. Since spraying the number of roaches, spiders, and insects I have found in the house have stopped. I highly recommend. I have been using suspend for 15 yrs.

Great product. It does the job. I spray about twice a year. I live in a row home. Keeps the critters at Bay. I highly recommend this product. You will not be disappointed.

Stink bugs did not like this product
Review by Raymond / (Posted on 11/11/2019)
I use this for every critter I don't want
I spray this about 3 times a year and it really works to keep the ants, earwigs, roaches, and scorpions out of house. It doesn't harm my free-ranging chickens or other pets. Our neighborhood had an outbreak of bedbugs two years ago and I used it successfully for that as well.
Review by Mary / (Posted on 6/2/2019)
My elderly in-laws' home was infested with roaches on the inside and spiders on the outside. They're old, tired, and one of them is dealing with the aftermath of a stroke so they're not really able to get around to clean everything and get rid of the pests. My wife noticed it last week while visiting them and came home mortified. When she told me what she had seen I immediately did some research and found that Suspend SC has, by far, the best success rate with roaches and spiders. I bought a pint of it and went ham on that house, inside and out, this weekend.

I went clean up around there and sprayed afterwards on Saturday morning. It's Monday now and I stopped by on my lunch break to check on things. I counted 19 dead roaches, mostly baby ones, 2 dead crickets, and 1 dead spider just on the inside. The outside is hard to tell since when I cleaned I hit all the spider webs with my pressure washer so they were already gone but I'd imagine anything that crawls on the bricks where I sprayed is going to be dead as well.

After a day and a half the inside looked like roachmageddon. I couldn't be more happier with the results. My in-laws are thrilled as well.

It's what the pros use because it's the best!
We have never used pest control companies since we found this product years ago. Had a friend who was our bug guy years ago and this was what his company used. I mix double the recommended amount in a 2 gallon sprayer and we don't see a single bug for a year. Here in Las Vegas, it's common to have scorpions, spiders, German cockroaches, and windscorpions (if you don't know what they are, look them up. They are scary, we've seen them). This works for all of them! Pet safe but it's best to let it dry before letting your animals near areas sprayed. Never had any issues that way. Our property is over 7,000 sq. ft. and the house is 2,300 so. ft. and I cover all of it inside and out with 4 gallons of mixed once a year. Highly recommend it!

I will buy this Again and Again
I bought this product for the first time after moving to the South East where you have bugs that make cats look small. I sprayed this around the perimeter of my house and the next day i found everything dead and taking a sunbath. This stuff works and I save myself tons each year. It is safe around pets and little kids once it is dry. Love it.
Review by Awesome Product / (Posted on 5/14/2018)
Great product, kills many varieties
I used this all last year and just finished my bottle with the first application of 2018. So I am back to order more. I used it around the exterior of my home and the detached laundry room. I contend with fleas, ticks, earwigs, several types of cockroaches, centipedes, and everything else the desert can produce. Last year we had a run-in with bedbugs. I locked the bedrooms tight stuffing towels under the interior doors to keep pets and people safe and opened all the windows, then I sprayed the edges of the carpeting, the bed frames, the box springs, and the underside of the mattresses. I did this early on a hot day so everything could dry very well before anyone needed in the rooms. It worked great. My chickens love when I spray outside because the next morning they have a feast. I usually don't have to spray again for about 8 weeks.
Review by MaryV / (Posted on 5/10/2018)
It works
Scorpions are creepy and this stuff keeps them away. I use it every six months on the perimeter of the house and in the garage. If I wait too long between applications, I'll get one of these unwanted visitors in the house. Eeeeek.

Always Pleased with DIY Pest Contriol
I own a motel and get what I need for pest control from DIY and am extremely happy with not only the products and support, but the excellent service! And, have saved a pile of $$ since I don't need the pest control service which charged a kit and we always had bugs with them. Now, we DIY and are bug free except when a guest brings them in.
Review by Jay / (Posted on 11/30/2017)
great product
I ordered this because I was paying over $500 a year for pest control. My Uncle has a vineyard and has never paid for pest control. He suggested I try Suspend SC. It worked great. Not one site of a bug anywhere. Will buy this again.
Review by april g / (Posted on 9/26/2017)
Best overall
Suspends SC is my go to pesticide. I use it around our lake house and home for about 8 years. It works very well. It has a slight odor, I cannot smell it but my wife says she can smell very faint odor but after it dries in about an hour no odor and safe for my dogs. I use Tempo SC in the house no odor. Tempo has a faster knock down which I want inside but the Suspends has a broader range of insect control which I want outside. I have not tried Suspend Polyzone but I plan to give it a try in the future.

This stuff is no joke. We have American Cockroaches coming out of the sewer. They come out of the pipes in our house and once they hit a area that has been sprayed they are dead dead. In other words when we see them they are dead or dying. No more running away at lighting speed-they are one of the fastest bugs in the world. Anyway great stuff...

Gypsy Moths be gone
After wrapping my oaks with burlap I sprayed on the Suspend SC, and the next morning there were dead caterpillars on the burlap. Since then my son discovered he also had gypsy moths, so we repeated the application. I just checked his trees today, at his suggestion I looked at the tree above the burlap, and there were dead caterpillars everywhere.
The product arrived quickly after I ordered it, and because it takes so little to mix a gallon, I'll be ready for next years assault both here and at my sons.
I'm very happy with this whole experience.

Best Product On The Market
Suspended SC is by far the best pest control I have ever used. I have been using it for 3 years now and I recently ordered my 3rd pint from doyourownpestcontrol.com It works better than advertised. The company and the product is the best.
Review by Gator / (Posted on 6/7/2016)
Great product
I've used Suspend SC since 2004 with great success! I highly recommend it for most household pest. DIY is an excellent company to work with, they are customer friendly and very efficient in service.
Review by Scorpion Wrangler / (Posted on 5/2/2016)
Reliable product
I have bought this from DIY Pest control fro the last 10 years at least. Always fast delivery and as far as Suspend SC, it is a great all around pest control. We have lived all over the country and it stops, roaches, spiders, ants, scorpions and a multitude of other common house pests. Highly recommend it and that you read the label and use all safety precautions when applying it, once I didn't and knew I had applied the product.

Great product and company!
I have used this product before (lasted about 2 years even with sharing it with my friends) and it works great for my needs. Had a fly problem in the barn area, it worked great. It has also killed any other pests such as spiders, beetles, wood roaches, etc...
I have recommended this product to many of my friends/family and will continue to do so.
DIY Pest Control has been great to deal with as well with great prices and quick shipping.

Been using this stuff for many years here in West Virginia and It works and works fast. Soon as anything hits it there belly up. No other pesticides work but this does.

So Long Mr. Bug Man
I have been using this product for over 10 years. In Georgia, we have every bug imaginable, especially in the spring and summer months. It works great on beetles, spiders, wasps, and pretty much any other insect that comes in contact with it (including termites). I spray around the outside perimeter of the house every three months about 2 feet out and 2 feet up as well as around windows and doors. I also use this product occasionally indoors all through the downstairs and kitchen area. There are no bugs anywhere. If they are here, I never see them. I have saved huge dollars over the years with no pest control company needed. So long Mr. Bug Man...go take someone else's money.
Review by Patrick / (Posted on 9/26/2015)
Works great, no more exterminator fees
Every three months I mix up about six gallons of this and spray the perimeter of my home, porches, soffits, and every nook and cranny I could find. There's plenty of bugs down here in South Carolina and this stuff keeps them in check. I have a light stucco home and this does not stain and stays put.
Review by Catboss / (Posted on 7/28/2015)
My wife and I bought a house that was neglected for some time. We noticed in an upstairs addition that we had a very large carpenter ant problem. There were flying ones and soldiers everywhere. We called a local pest control company that I believe was using this product. I befriended the guy and he told me the product. Found it online here and bought it. Use it inside and outside with incredible results. Kills spider, beetles, ants and even earwigs, which we have a lot of. Inside application last longer due to the lack of the elements. One application indoors lasted for 2 years. When we saw bugs in the house, which is rare, they are dead. GREAT PRODUCT!!!!!!.

Great, reliable product.
Husband and I have been using this product for about 8 years. We love it! It does a great job of insect control. Also, I've never had a pet or person get sick from it. Works well on my roses and other plants too. Love it!

I'm a pastor of a good sized church in the desert. We were paying a local pest control company $80 a month to spray. It worked ok but seemed like we still had issues. Bought "Suspend SC" and we've never seen so many dead bugs! Its been a couple of weeks since we sprayed and still walk in every day to more dead bugs! It's working wonderfully! We are talking on 2 gallon covered over 16,000 sq feet!! I HIGHLY recommend "Suspend SC"
Review by Pastor Randy / (Posted on 5/26/2015)
best i've ever used
Been using Suspend SC for 12-15 years. Wonderful stuff. used to have hornets build nests under overhangs and overhead door corners. it's been years since any new nests have been built. i spray late spring early summer. very effective on the japanese beetles(ladybugs) spray around windows and doors and it keeps them out and kills them. had black ants around the front porch and in a flower garden, soaked them both and the ants are gone. guess i can't say enough good things about Suspend SC
Review by jeff / (Posted on 5/24/2015)
Good Stuff
Had a scorpion problem in Arizona. Sprayed the perimeter of the house, inside garage and up exterior walls about 3 feet. Haven't seen a scorpion in the three years I've been using this. I spray every six months.

great product
I bought a pint of this Suspend SC a year ago, to get rid of centipedes ans spiders.. BOY does it ever work! Within a week of my first application, the only bugs in my house were DEAD ones. My last app was about 4 months ago, and now I see a spider once in a great while, so I know it's time to reapply. I use a deck sprayer, inside and outside. Haven't seen a centipede in over a year! I use it every 3 months.
Review by Dick Uhrlass / (Posted on 3/3/2015)
Not bad, but not great either
We have some tough spiders here in east Texas outside on our patio. We live in a lake community, so we have a fair number of insects, to include these tough, tenacious spiders. I've sprayed twice now within two weeks and it still hasn't taken care of the problem. I almost doubled the dosage the second spraying. And I soaked things down. Will keep trying. Maybe you will have better luck.
Review by Sick of spiders / (Posted on 10/23/2014)
Here in Atlanta we have a large variety of bugs. About 4 years ago we noticed our professional pest control company was using this product. We went on-line to do-it-yourself pest control and bought the exact stainless steel sprayer and the SUSPEND SC. I really only spray the outside perimeter of my 2 homes once each quarter. It works great, no complaints or bugs. One bottle will last me about 2 years or more. It has certainly saved us a lot of $$ over the years.
Review by Dan / (Posted on 7/11/2014)
Wow did it work fast
Had a moth problem that had not seen before. Using Suspend SC along the window sill and threshholds both inside and out did the trick. No more moths. Decided to spray the entire perimeter of the house and garage to prevent other intruders.
Review by Strangebru / (Posted on 4/26/2014)
Not really sure
It's a temporary help, but I notice the roaches keep coming back. I guess I need to call a professional.

**********DIY RESPONSE***********

Suspend SC it typically a good product for large sized roaches, but it is ineffective against the small German cockroach. If you are battling small roaches in your kitchen and bathroom areas then a product such as "Maxforce FC Select Roach Bait" is the best option. Call us if you have questions: 1-800-476-3368

Kills bedsbugs
I thought bed bugs for many years I used bug bombs and sprays labeled for bedbugs also "natural remedys" nothing actually got rid of them. If anything worked it was for a short time. I moved replace my furniture and they came back. The only thing that has worked was Suspend SC I bought four bottles and only used one bottle and had some left. It is good for other pests so the bottles leftover I'm still going to use. Dont forget to get a sprayer. Thank You Do It Yourself pest control for supplying such a great product. I wish I would have known about this product years ago. I used it I could have saved thousands of dollars. Thanks again doityourselfpestcontrol.com
Review by Rich / (Posted on 2/6/2014)
Great stuff!
I've been buying this product for over 3 years now and it's the best I've used. Living in Las Vegas, we really need to use something good and affordable to keep the pests away instead of paying someone else to come once a month to use their diluted stuff and still have occasional bugs. I use double of the product and add the amount of water it calls for and we don't see a single insect in the house for at least a year. Just dead ones outside. We buy a pint and I can do inside and the perimeter outside, my sisters, my uncle, and my mom's house and still have a bit left. It doesn't seem to do much to keep flies away but for the price and effectiveness, it works great! Always shipped fast, very satisfied with this company and their easy-to-use website.
Review by Teresa / (Posted on 11/10/2013)
Excellent product. I use it in and out twice a year for spiders and other invaders. Definitely cuts down on the pests.
Excellent service, quick shipping.
Review by Jim in Iowa / (Posted on 10/29/2013)
does the job!
Puppy has SEVERE FLEA SALIVA ALLERGY: After disappointing results with consistent applications of a 'big box store' product I did my homework and ordered Suspend SC. Coupled with Precor IGR and carefully FOLLOWING INSTRUCTIONS the environmental flea issue (as well as all other undesireables - especially the invasice stink bugs!) was quickly, thoroughly resolved.
Will continue to use as directed and repurchase.
Excellent customer service from DIY.

Dreadful Spiders
We have a serious problem at the Lake house in East Texas with darn spiders. Been using this item for a couple years and it seems to work with some degree of success. Spiders are very small and make little webs everywhere around the houses, windows, doors, etc., and bugs get entrapped which is a nuisance to have to blow down or wash with the hose every month or so. They will come back so we bought about a two year supply.
Review by Sugars Pop / (Posted on 10/25/2013)
Love this product
I love this product Suspend SC. I have used this product for several years. I used to get polluted with Asian Lady Bugs in my home. I spray this product on my house and around the perimeter in late September before the beetles swarm. The beetles die outside and I have no beetles inside of my home. This product does not stain my vinyl siding, does not stink, and does not kill your plants and shrubs.
Review by Belinda / (Posted on 10/14/2013)
Really Great Roach Control
I have used Suspend for over six years in my house and out-buildings. The only roaches I see now are already upside down, or moving slow. About one treatment a year seems to do the job for me.
Review by Wisbee / (Posted on 9/23/2013)
Outstanding Product!
I bought my house in 2006 and purchased this product for Camel Crickets. I was terrified to go to the basement once I realized they were there. Did some research on this web site found the insect picture; decided to try Suspend SC. OMG killed everything and keeps re-entry impossible to ALL that try to invade my home. This is a 10 Star product! I spray my house twice a year with this product Spring and Fall. There are NO insects or pest here.
Review by Homeowener 2006 / (Posted on 8/17/2013)
Outstanding product
I was a bit on the edge when I bought this product for the first time and wondered if it was going to do what the business said it was going to do to keep those insects that seem to get under everyones skin during the summer months. So, am I happy I bought Suspend SC, YES, YES, YES, it is the best purchase I could have ever made for the do it your selfer. I just don't see any insects anymore.

Ok for occasional invaders
I am in the pest control field and I wouldn't recommend this product for bedbugs they are resistant to it and all it does is scatter them if this is all you got than make sure you use gentrol. But if you really don't have a problem it's great for perminiter sprays for the occasional invaders

Very Satisfied
We moved to Florida 4 years ago and saw a Do-It-Yourself Store.
We bought Suspend SC and have used it since. We are still on the same bottle. We have never had bug issues and would definitely recommend it.

Good Product
I have used this product treating my own home two times. It works well for killing fleas and Bed Bugs. When using this product always remember that less is more. If the area is soaked with it the bugs will avoid the area.
Review by Hate Bed Bugs / (Posted on 1/23/2013)
Better Shelf Life than D-Fense
Both Suspend and D-Fense work equally well in controlling pests, but Suspend seems to store better. In my experience, D-Fense tends to get gummy or stringy if it sits on a shelf too long and can clog spray mechanisms. Suspend seems to retain its consistency better over time.
