Cyzmic CS Insecticide

Walt Cline - Pest Control Professional Pro Tip: "Cyzmic CS Insecticide has an active ingredient that has been the workhorse of the pest control industry for over 10 years. I like it for controlling the insects that enter from the outside. I don't suggest Cyzmic CS for ants or german roaches. Cyzmic CS is comparable to Demand CS but less expensive. You can pick up a really good sprayer for about 20 bucks if you get the Cyzmic -Sprayer Combo

Target Pest

Cyzmic CS controls a broad spectrum of insects including: Ants, Bed bugs (adults), Bees, Boxelder Bugs, Carpenter Bees, Carpet Beetles, Centipedes, Cigarette Beetles, Clover Mites, Cockroaches, Confused Flour Beetles, Crickets, Earwigs, Firebrats, Fleas, Flies, Lesser Grain Borers, Litter Beetles (adult/immature stages such as Darkling, Hide and Carrion), Millipedes, Mosquitoes, Pillbugs, Red Flour Beetles, Rice Weevils, Saw-toothed Grain Beetles, Scorpions, Silverfish, Sowbugs, Spiders, Termites (above ground only), Ticks, Wasps.


Bedbugs: Clean floors and surfaces by vacuuming. Apply as a coarse, low-pressure spray of Cyzmic CS to areas where the bed bugs may be harboring. These areas include baseboards, crevices, behind bed frames, beneath beds, bedsprings. Cyzmic CS is not labeled to spray directly on mattresses or any surfaces where people will be sitting or laying. Remove infested bedding and launder it at high temperatures.

Cockroaches, Crickets, Earwigs, Firebrats, Silverfish, and Spiders

Cockroaches, Crickets, Earwigs, Firebrats, Silverfish, and Spiders: Spray Cyzmic CS as a low pressure, coarse spray in corners, baseboards, around water pipes, storage areas, closets, cabinets, under and around kitchen appliances (refrigerators, stoves and ovens), underdrawers, and any areas where insects hide.

Bees, Flies, Mosquitoes, and Wasps

Bees, Flies, Mosquitoes, and Wasps: Apply directly to walls, ceilings, window screens, and other resting areas as a residual surface treatment.May be used inside residential buildings as well as in and around carports, garages, and storage sheds; also see Outdoor Surfaces Use.Use caution when treating nests of stinging insects as CYZMIC CS does not provide instant knockdown. Protective equipment for the applicator may be required. Treat bee, wasp and hornet nests late in the day when most insects will be present. Allow 2-3 days fo the colony to die and repeat after 21 days if necessary. 

Carpenter Bees

Spray enough to wet the wood where these bees may cause damage or thought to be active. Try to spray early in the springtime to prevent them from drilling into the wood. When bees have infested wood, surface applications can help control embedded larvae and bees that emerge from the wood. 

Pantry Pests

Pantry Pests(i.e., Carpet beetle, Cigarette beetle, Confused flour beetle, Lesser grain borer, Red flour beetle, Rice weevil, and Saw-toothed grain beetle): Apply to cupboards, shelving, and storage areas.Remove all utensils, uncovered foodstuffs (or any having original package opened), and shelf paper before making an application. Allow treated surfaces to dry and cover shelves with clean paper before replacing any utensils, foodstuff, or other items. Any foodstuff accidentally contaminated with treatment solution should be destroyed.

Boxelder Bugs, Centipedes, Millipedes, Pillbugs, and Sowbugs

Boxelder Bugs, Centipedes, Millipedes, Pillbugs, and Sowbugs: Apply Cyzmic CS around windows and doors and other areas where this pest hide or may enter the buildings. Treat baseboards, storage areas, and other locations. Also see Outdoor Surfaces Use. 

Cluster Flies

It is best to treat Cluster Flies in the early fall or late summer (before you see them landing on surfaces). Spray siding, under eaves, around doors and windows. Pay particular attention to south-facing surfaces.

Surprisingly this stuff works well
My girlfriend and I just purchased a house in the high desert. When we moved in we were killing anywhere between 1-3 huge wolf spiders each day on top of countless beetles and other types of bugs. We were going crazy because we had to inspect everything in the house before we could touch it. I bought an 8 oz bottle of Cyzmic CS to try it and upon spraying it I have not seen a single wolf spider in over a month and are now getting small spiders every so often inside. We now have to clean up dead bodies of not only spiders but cockroaches, beetles, flys, and so many more. I was surprised that this stuff actually worked because I did not believe the reviews. We just noticed a huge anthill today with hundreds of large black ants, and after we sprayed it took roughly five mins and we noticed there were so many dead bodies in our lawn. After seeing how this stuff works, and upon running out I decided to purchase the 32oz with no hesitation. This stuff actually makes me feel comfortable in my own house again without having to worry about a large wolf spider climbing across my couch while I am sitting there (yes, that actually happened).
Review by New Homeowner / (Posted on 7/15/2020)
Did what I bought it for.
Just built a new raised back deck and wanted to keep the carpenter bees away before I could stain/seal it. The bees were flying around the new wood, probably going over the menu. Anyway, I ordered this, followed the directions exactly for carpenter bees, and they, quite literally, instantly went away. I was swatting four or five bees a day with a tennis racket both before I rebuilt the deck and after. Haven't seen them back since! I sprayed about two months ago and still haven't seen any. I was so impressed that I also sprayed the front porch as well. There was already several bee holes in the wood, so I just sprayed the inside of the holes and all over the porch. I swear, I haven't seen a single carpenter bee since. Anywhere. I used the product on those stupid little black ants (sugar ants, I believe), and that killed them as well. Sometimes not on contact, but once they're hit, they die. It doesn't prevent them from coming back, as I had hoped it would, but I bought this for carpenter bees, not ants.

Excellent results
I bought this for bees boring in my painted shop. I realized when I received it that it was a wonder chemical. I don’t think there is a bug that I know of not listed on the stuff. I have had excellent results with it. I have recommended it to all my family n friends. The only thing the rain washes it off and you will have to reapply after a big rain outside. It’s that way with all chemicals though if not having oil or something making them waterproof. I highly recommend this product.

Fly control
House flys swarmed west side of building on warm sunny days. Thousands of flys would congregate on anything light colored. I sprayed a heavy coat of cyzmic cs on all light colored surfaces. Flys immediately left and never came back. This stuff is truly great!
Review by dan / (Posted on 5/6/2020)
You won't be disappointed
I was beginning to have a pretty bad infestation of Carpenter bees and this product took care of the entire problem. I was also paying for pest control until I realized the various applications this product can be used for. Now I doy own spraying once a quarter and save myself hundreds of dollars a year.
Review by Oz / (Posted on 5/6/2020)
It kills carpenter bees, but not so much on repelling them
It will kill carpenter bees, but it did not repel them as I had hoped. I sprayed all the rafters under my patio roof. Several fell dead on the floor, but I did notice some coming back over the next several days looking for their holes a plugged.

Seems to work very well, I’ll see if it continues this spring
I’ve used it twice, I spray every 24 days, went from seeing 1-3 roaches a day or so, to only one in last 40 days
Review by Will / (Posted on 1/6/2020)
Good product
I used Cyzmic to spray a friend's house that had a major spider infestation. Spiders and webs everywhere, looked like Halloween. The old house had never been sprayed. I gave the exterior a triple treatment, and the interior a single treatment. Visited six months later. Significant difference. I located a few webs, but did not see any spiders. Much improved. I gave the exterior another single treatment. Will probably take several applications, but this product clearly works.

Seems to work well. It was mainly used for spider control outside and under my house. I will buy again when I have used up what I have.... It was applied using a 2 gallon pressure tank sprayer...

Need more stars**************************************************************
Been using this product in my barn for the 4th year and again very pleased with the results. No carpenter bees, no wasps (a few maybe for a day and then they leave or maybe die..not sure...hope they die), no mud daubers, and no spiders. Had to spray the bottom of my second story deck (treated wood) because the carpenter bees decided since they couldn't have my barn, they would take my deck. That was two years ago and this year I had to respray. I think it is keeping the stink bugs and Asian beetles from hanging out on the deck, too. Use just a tad more than the instructions call for. You won't regret using this stuff. At least you will see results.
Review by Janette / (Posted on 7/2/2019)
I like this product
Seems to be working great. I killed 1000s (it seemed like that many) Japanese beetles infesting and devouring an ornamental tree. I've been using it on part of my yard because it's a terrible year for ticks. I have also sprayed a little bit inside my house on cabinet shelves just in case any weevils or other undesirables want to eat some of my food. I'll be ordering more when I run out of this.

Best Spider Killer on the Planet
I used this in mid-May, just after the last rains. Exceptional spider knock-down. We have black widow and a host of other types of spiders. Also eliminated silverfish. It's been a month since spraying, and happy to report 'no spiders and no silverfish'.
Review by LaurieP / (Posted on 6/20/2019)
We have had a major problem with bumble bees drilling holes in the wood exterior of our house. Holes everywhere. Got the product and prayed as directed and it killed bees immediately. We noticed that it also killed the bees that were hatching out of the holes. Highly recommend. Will use it from now on!
Review by Chinky / (Posted on 6/14/2019)
It works!
Very easy to use. I mixed per instructions in a 1 gallon sprayer. Sprayed under all the hand rails on my deck to try and get rid of carpenter bees. The next morning the ground was covered in dead bees. Weeks later I found dead larva. Apparently the eggs hatched and came in contact with the residue. Highly recommend.

Sprayer is worth the cost and good good results with the Cyzmic
If you don't have a sprayer, this is a good one. We have sprayed mostly for Black Widow spiders and they are not making webs everywhere like they were so good riddance. It's easy to apply with the sprayer that come with the combo so well worth the money. I am very impressed with the sprayer and the two nozzles. My wife has even noticed the difference.

Great Product at a Really Good Price
Purchased to deter scorpions that pledge my house and also spiders. Scorpions found upside down and dead, spiders departed, those that didn't were found dead.
Great Product!

works just as good as the pro’s at a fraction of cost.
I have used this product for several years and it works great. Carpenter bees, spiders, ants and even small roaches are no longer a problem. If I do see them now, they are dead.

Great stuff
We have had a serious spider issue since we moved in new house several months ago. We have had seen 3 black widows, 2 were on my front porch and 1 in my garage. We have many other spiders and bugs to. They string webs all over our windows etc. well I bought cycmic C.S. and sprayed the first application several weeks ago and I mixed 1oz per gallon. I wanted it stronger. All I see now is dead bugs, dead spiders or soon to be dead ones. This stuff is great and I will for sure keep this on hand. It left no staining at all. All it left was an invisible to us barrier that kills spiders and many other bugs. Before spraying I removed all webs from windows, eves and all. No new ones after I have sprayed.
Review by Matt / (Posted on 9/26/2018)

I was just thinking 10 mins before I received this e-mail that I haven't seen a spider in two months. That's a first for years and years.

The Nuclear Option
So my wife and I bought a new home (new for us). We also apparently bought it’s brown recluse problem. I had been using glue traps to catch the little demons... but this year, wow it’s like they tripled in numbers. Needless to say glue traps weren’t cutting it anymore. So, I did some research and found that I needed to up my game. So I purchased delta dust, tempo spray and cyzmic; all from do it yourself pest control. Brown recluse die wonderfully slow, effective deaths with delta dust. Tempo spray is much quicker... still good stuff. Now, Cyzmic CS, this stuff... let’s just say it’s like a nuke went off in my house and the brown recluse citizens aren’t fairing well. I did double the dose in the pump sprayer, but I sprayed every base board, every corner and every threshold. I also went over every window and around every bed. I was curious about the products claims of a strong residual. Let me tell you, after seeing dead brown recluse all over the place, I’m a total believer. I can’t wait to spray again to be honest. I feel like I’m finally getting the upper hand. I’m not sure if I’ll ever totally eradicate them, but one thing is for sure their lives are a total hell and I’m bringing the fire upon them. If I could give 6 stars I would.

It Will Kill!
Here it is my third year of using this fantastic product.
For years I endured lots of insects in my barn, especially carpenter bees and those God forsaken giant wolf spiders. One application of Cyzmic and no more bees (of any kind) and no more spiders. Not much flying or crawling in my barn these days and a .410 took care of the raccoons.
To anyone contemplating buying this product from this company. You will not be disappointed. Follow the label instructions and set yourself free. Your only regret will be the money wasted on those worthless products from the box stores.
Thanks again Do-It-Yourself Pest Control for your product recommendations and for the sprayer wand replacement.

Second choice for second time for bed bugs
Title means, I used a different product when I 1st discovered them, it worked ok along with cimexa dust an cleaning for a month before hand doing all the steps of preparation first, took four months to see no more, thought I was in the clear, went on vacation and came back and nope there they were and there was no body home but the animals and a caretaker dropping in and quickly leaving lol. So I bought this the second time, it was not as heavy an infiltration as the first but this got rid of them along with burning the burning the furniture or some of it, I don't recommend that unless it is legal where you live. but after a few month of spraying every two weeks they were finally gone.

Cyxmic Solved our Spider Problem!B
The sprayer worked very well, and the Cyzmic product was a dream come true. For years, we have had such problems with spiders in/on/under our patio furniture (all kinds, including big brown widows.) A quick spray two days before our Labor Day bbq event and... NO SPIDERS. No lingering smell, and no webs coming back even now, 3 weeks later. Thanks for the helpful recommendation. This product really works.
Review by Bill in San Diego / (Posted on 9/25/2017)
Awesome Product
This product was incredible at taking care of our spider problem. Initially we were a little intimidated by the product, just simply because we knew it was a strong chemical, but the process was actually very easy and very effective. We literally had spider webs EVERYWHERE on our deck. One spray down with this product and they all went away very quickly. I would highly recommend. Prior to our purchase we reached out to a pest control company and the price for them compared to this product was over the top. It's not necessary to pay those expensive bills, when you have this product.
Review by dayttonn / (Posted on 9/12/2017)
Look No Further! This stuff is awesome.
Okay, now listen here! Look no further if you are wanting to control pests. First, the people at DIYPS are awesome! Great customer service. I lived outside Atlanta 15-21 years ago (can't believe it's been that long) when I first became a customer using Deamon WP - also a great product but leaves unsightly white residue on house when dried. Switched to Czymic 15 years ago after moving to the Pacific North West and couldn't be happier. No sightly residue but you know it's there because you'll see nothing but dead bugs for months. Have used on spiders, yellowjackets, fire & other ants (mounds), mosquitos, flies, etc. (w/great success); preventively for fleas, ticks & termites. Products from HD/Lowes/big box stores just suck as they're typically short lived at best. Spray this 1x - 2x a year and forgot about it. I only spray externally & under house 1x a year. No need to spray inside but it's okay to do as needed w/ proper precautions. Simply put, this is an awesome product. I buy the big bottle and use it over course of 3-5 years w/ no diminished effect whatsoever - just tested this w/ a 4-5 yr old bottle now empty. It's just so wonderful, helpful and provides such a piece of mind to purchase a product that works better than expected - the way it's advertised. Many thanks to both the Cyzmic and DIYPC people! Cheers.

Review by Texas / (Posted on 8/5/2017)
Have used this product outside and inside of my home for a couple of years. Great for killing spiders, ants, roaches - none of these creeps want to come around my home anymore. Have a rock garden and sometimes fire ants think they have found a home - not so quick - I spray and they are gone. I live on 11 acres and in the south. Fire ants are hard to control, but with this product, I keep them away from my living area as well as other types of ants and other bugs that plaque the South!.
Review by JimmyJo / (Posted on 7/17/2017)
it appears to work pretty well
So far it appears to be working. My only issue is the instructions ask for a certain measurement but the bottle use to measure the amount of chemical does not agree and you must compute it manually to mix it properly. Also I can't get one of the tips to snuggle down tight enough to not drip so the main tip sprays out a lot more than I would like it to for the small inside areas in which it is used
Review by Shelia J / (Posted on 7/5/2017)

Used this again this spring/summer
Second year of using this is my beloved barn. The carpenter bees were making a little bit of a comeback but now, as of June 25, not seeing any. Only seeing a few wasps and mud daubers in the barn;.
I spray the peak of the barn, the rafters and the baseboard area, wood framing on the doors and walls.Had to slack up a little in the area where I stable my horse. Not sure if this is safe for animals. It hasn't fazed the raccoon family living behind my tack room wall. I know one thing. This product will kill spiders, carpenter bees, wasps and stink bugs dead. (I do add a little extra Cyzmic as my bugs seem to be tougher than most.)

Cyzmic CS
Huge spider phobia and so far it's the best since diazinon
Review by Nursysue / (Posted on 6/16/2017)
Very effective
We paid $600 last year for a franchised exterminator to eliminate the carp bees around our gable ends. They claimed to have "treated" it twice. We saw no difference in activity. I applied Cyzmic this year myself from DIY. There were little black bodies all over my roof within 2 days. I also hung the trap and captured another 6 or 7 so far. The Cyzmic didn't stain the vinyl siding and was easy to apply with a pressure sprayer. It's very concentrated so the bottle should go a long way. Good stuff.

Cyzmic CS
A few years ago, my covered porch had a Carpenter Bee problem. We sealed all holes and repainted the porch, but, this Spring they began hovering around the eaves again. They had not bored any holes yet, but we treated all eaves and fascia boards with Cyzmic CS spray.
Amazing! We haven't seen any Carpenter Bees and our porch is still hole free! Great product!

Great product
I had a enormous amount of boxelder's around my foundation and siding. I came across this website and product and decided to try. Directly spraying the insects did not seem to harm so i went ahead and sprayed the foundation and siding including the inside of my pole barn. After about 24-48 hours I noticed tons of dead boxelders laying on the ground and now I cannot find any of these insects crawling anywhere. This product is great.
Review by Frank / (Posted on 4/29/2017)
I had my doubts as there are so many products that "claim" to be the best. Your product worked as you claimed. The darn Carpenter Bees have been a constant pain for years with no treatment that seemed to eradicate them. The bees just get a whiff of the product and they run to my neighbors house! Upon the application the bees are no longer. I cannot begin to express my thanks for this product.. It has surpassed all my negative expectations. I will be ordering more now that it had worked so well. We have a lot of wood around the house. The plugs also work very well indeed. Thank you for your outstanding solution for a pesky problem.

The recommended dilution for scorpions is .8oz/gallon but this is not a 'knock down' dosage per the pros. I use 1.25 oz/gallon & this has eliminated our scorpion problem. We live in the phoenix area where scorpions are a problem.

I own Vet Pest Control out here in Surprise, AZ and scorpion control is a must. I switched from demand cs. I still use the same 1 oz to 1 gal mixture for scorpions. My customers overall seem to be pleased and have not had any issues on the switch. The only issue I have is the quart bottle is always 29-29.5 oz instead of 32. After 10 bottles that is one bottle less thank you should have. Still cheaper than demand cs in power sprays.

Cyzmic CS
I used Diazinon in the past until it was taken off the market and a friend told me about Cyzmic CS and have used it every year and works great! I have a huge phobia of spiders and this stuff works. Thank you!

Good Product
Had carpenter bee infestation on redwood beams and posts on patio. Used pump sprayer with product mixed as directed and saw difference in about a week. Sprayed a 2nd time about 2 weeks later and carpenter bees are virtually gone now. Have only seen one actually land and try to bore a hole. Had to caulk the old holes which helped eliminate bees as well. Works as suggested. Thanks Do-It-Yourself Pest Control!

Extremely satisfied with this product.
I purchased this product to eliminate Carpenter Bees. The bees had become a major problem endangering the structural integrity of some exterior roof beams.

This product eliminated the problem. Bi-monthly applications will prevent any further damage.

Didn't work for my carpenter bee infestation.
I have a carpenter bee infestation. I spoke to the customer service guy at do ou own pest control. He suggested I may only need to spray with Cyzmic. Sprayed on Friday. New saw dust Monday morning. Just bought the dust spray in the holes. Hope the Cyzmic will work for other critters.

Very effective
I've used Cyzmic CS to control Stink Bugs for years. It is simply amazing how effective this stuff is. Simple to mix and simple to use too. You cannot go wrong with Cyzmic CS.

Love it!
Will be ordering again since spring is coming. I always used diazinon until it was taken off the market and told this is the next best to use and it is!

I have a huge phobia of spiders and so far has worked well and keeping them away!

Great Stuff
I used Demand CS a lot when I was a professional Pest Control Tech. This has the same active ingredient. It really works well, especially in hot weather. I make sure I get it into all cracks and crevices and put down a good barrier. I don't have bugs like the neighbors do.

inexpensive quality
easy to use, inexpensive and very effective - no stains is a huge plus

Great stuff for the cost conscious
Mix as much or as little as you want in a cheap sprayer from the store. This and the crack and crevice tool are all you will ever need.

Roaches and Spiders No More
I was having a terrible time with large cockroaches and spiders crawling across my feet at my computer desk (creepy). The desk is next to a wall with a raised floor. I have a feeling the bugs live in the space under the raised floor and come out at the seams. I sprayed this all along the seam at the baseboard. I haven't seen a spider since and all the roaches that come out now start twitching and die in the living room floor. haha

Works great in the Florida Keys
I hate scorpions and I used to get them in the house. I use Cyzmic CS at a little greater than usual strength and anytime I see a scorpion now, he (or she) is dying or dead. Perfect. Of course there are no other pest insects in the house either.
Review by Fish Stories CJ / (Posted on 10/25/2013)
Unbelievable stuff. You can't go wrong here.
I've been using this now for about 8 or so years. Switched from Demon & Cyper WP because they leave a white residue once dry. If you have a dark colored house, this is unsightly. Not this. Drys clear and lasts for months. I spray twice a year. and that's it. No bugs. Just a great all arond insecticide. So is Demon and Cyper, if you don't mind the white residue. Highly recommend. Take care in spraying. Use safety glasses, dress properly and use mask if your so inclined. After seeing what it does to bugs, spiders and the like, I certainly don't want to ingest this stuff. There have been no ill effects around pets or kids.....or me. Just keep the fur & yur children away when wet and don't spray in areas where they are likly to come into contact. No need as spraying in perimeter and cracks, up high in awnings is good enough.

Last a long time
Sprayed this back in march and it's still working against earwigs. Haven't seen one in a long time.

The only good bug is a dead bug
Had bugs & spiders. Sprayed this (mixed with water of course) around the house and I haven't seen a bug or spider in the house in over a year. Definitely recommend this stuff. Magic? Don't care.

will not work for saw-tailed flies
Sprayed, sprayed and sprayed again: no effect on these saw tailed flies.

No More commercial Pest Control
I was paying $35 each month for pest control ($420 per year) and still seeing roaches between spraying. I fired the commercial guys and started doing it myself. It now only costs me about $3.00 per month (saving $384 per year) and there are NO bugs. I highly recommend Cyzmic CS.

Good product
Use it instead of commercial pest services. Works great. I apply monthly to the outside of the house, and quarterly spot treatment on the inside. No bugs!

Awsome product
I have seen great results from this insecticide. Spiders do not stand a chance. I highly recommend it!!

Recommened it to local friends
We bought this product because we had bed bugs and it worked after two applications. We told a friend about it, he asked us to order it for him because he had fleas and he said it worked. Two other friend's have asked us to order it for them after. I HIGHLY RECOMMEND IT!!!

Pretty good against most bugs
I live in the south so we get a lot of random bugs coming in the house for most of the year except winter. I started spraying this stuff around the outside walls and underneath the sink in my kitchen. Since doing that for a few seasons I've only seen a few spiders and some occasional roaches. All other bugs have disappeared. This is my second bottle. Hope it continues to work like it did last year.

I would suggest Cyamic CS again to anyone
I would suggest Cyamic CS again to anyone. I had tried an Ortho product a couple of years ago, that I mixed with water and sprayed my house for Lady Bugs and it didn't touch them. I read somewhere that you have to spray in the fall for lady bugs, so that is what I did. I sprayed the Ortho last October...still had them coming in all over the place. It drove us crazy.I had to vacuum all day long. This time I used Cyzmic CS last fall...what a difference! No more beetles!. It also took care of my spiders and roaches..great product. They were very helpful on the phone , I will use this company again.
