Love this product
I ordered the product to deter wasps from returning to areas of the eaves they’d built nests in the last couple of years .. even though I sprayed later than my research suggested was best, this has made a huge difference. The residue it leaves has actually deterred them from building nests.

Keeping my fingers crossed
Ordered this product because it was listed on the work sheet of the pest control company that I use. They keep spraying but nothing seems to have been eradicated.
Ordered this product to see if I could do any better.
Sprayed both inside and out and I have to admit that I have seen far fewer centipedes than when the company sprays. I also gave a healthy dose around the foundation of the house, but it was in late fall, so I am keeping my fingers crossed that it will help in early spring.
So far so good!

Would recommend. Told my daughter about it for her ants.
Thank you to whoever made this!! No more asian lady beetles in the house. The last two falls and winters involved a ton of vacuuming bugs but I had only about 12 the first part of fall and have not seen anymore for the last week!! YAY!! I highly recommend .

Been using for years.
I mainly use this for scorpions and spiders but kills everything else also I spray heavy where bugs/scorpions might be able to get into the house. Before I used this product I'd find live scorpions in the house now when I find them they are dead and greatly reduced their numbers would recommend this product.

Good Results
Arrived quickly. I spayed with it and haven't seen any roaches since. I'm going to do a follow up spray just in case
Review by Larry / (Posted on 8/13/2018)
Will buy again!
I bought this, Vendetta bait gel, tekko pro igr and victor roach traps to check the progress and I'm amazed! I live deep in the woods and these products have effectively eliminated my bug problem.

Review by Yup / (Posted on 10/4/2017)

delivery was prompt. Used product upon arrival, boom they were gone before even doing the follow up treatment.
Great site, great products.
Thank you

good stuff
Used this last night on lady bugs and worked great.
Review by Tate / (Posted on 2/3/2017)
Moderate Success
Product did not totally stop the pest issue, but more importantly it left a white residue, which made me uncomfortable with pets. Prefer a clear after affect when using inside.

Professional grade for residential use
This product packs a professional punch for pest control for residential use. Highly recommend this product.
Review by Gast / (Posted on 8/17/2016)
this is the best product
i couldnt remember when I sprayed for roaches and other bugs, then i encountered 2 big palmetto roaches. freaked out. the next day i sprayed and the next morning there were 8 dead roaches in the middle of the floor. gotta love those results because you know the rest of them are dead as well in the walls. highly recommend this product.

Carpenter Bees BeGone!
Cyper WSP has destroyed my Carpenter Bee infestation. Used 2 packets in gal sprayer, sprayed all woodwork they were after. Over the next 3 days- driveway had bees dead and dying. Sprayed 1 pkt in gal inside and killed/ drove away Lady Bugs and Stink bugs. We live in the woods.
Review by Backwoods / (Posted on 5/20/2016)
Finally, one shot mixes.
The dry powder packs are great for long term storage. They disolve best in a little warm water. I can not speak for the Cyper WSP as this was preventive maintenance.

Best and only thing that works for carpenter bees
Review by Shep / (Posted on 5/13/2016)
So far so good
I mixed in a sprayer according to instructions to prevent wasps from building nests in the ceiling of a gazebo and under the eaves. Also on shutters where the wasps like to go. I covered up head-to-toe as the product rained down on me when spraying the ceiling. So far, after about 3-4 weeks, no wasp activity. I am hoping that a single additional spraying in mid-summer will be sufficient.

Works great use once a month. Had no problems with insects

Japanese Lady beetles dead
If you live in the Mid-west and are consumed by Japanese Lady beetles, this product kills them. I put one packet in a 2 1/2 gallon sprayer and coated the exterior of my home. I only went through half the sprayer on a 5000+ sq ft area. I gave the other half to my neighbor who reported excellent results as well.
Review by gilly / (Posted on 11/19/2015)
Seems to work really well
This stuff seemed to work really well. Saw many dead (and soon to be dead) bugs that came out of the wood work after I sprayed. The one thing I will add is I used more of than I thought I would so two packets (of the four pack purchase) was used around my moderate size house and under cabinets etc. inside. Thought I would only use one but still not a bad price for a four pack. Looking forward to using the other two after a while.

did nothing for roaches
I bought this for roaches, it was highly recommended by the sales person. I sprayed a whole gallon around and inside the house. I still have roaches, they must be the German ones the person was talking about.
My brother sprayed 2 times, a gallon each time in a mobile home. there were no dead roaches but still the same amount as before.
Very disappointed with results.

DIY RESPONSE: You are likely correct about them being German Roaches. Cyper WSP is highly effective against the large roaches that invade from the outside (especially when the weather changes). If you have the type that breed indoor known as the German Roach, you need a bait such as MaxForce Magnum: http://store.doyourownpestcontrol.com/maxforce-fc-magnum-roach-bait

Review by BABA / (Posted on 8/2/2015)
I was having a rough time with biting flies. My Dog's ears were becoming bloody and they seemed miserable. Petsmart stopped carrying the flyoff that I used last year. I was at my wits end, locking the dog's in the garage to keep them away. I tried this product and sprayed it up by the house and where they lay in the shade. I also bought a fly trap, but the dog's thought that smelled good too. Anyhow the dog's are happy, their hair has grown back on their ears. It took just about a month before I started seeing flies again. I resprayed and we are fly free for now. I'm already planning my second order.

Worked Great!!
This stuff got rid of a colony of Carpenter Bees that have been a problem for me for years.

I applied twice and they were gone.

I highly recommend it.

Love this product
Love this product, had a brown recluse problem and sprayed in/out the house and I spray every three months and works well for me.

Kills spider and other insects
I use this around under the eves of my home to kill spiders. It's effective for about a month depending on rain and humidity. Seems like it does a good job with anything else that touches it except the wasps.
Review by SUMYUNGUYZ / (Posted on 6/27/2015)
kills bugs!
If this is same product as Cyper WP, it is great. Have used it for years and recommended it to 2 relatives who have had the same good results. We have a scorpion problem in our yard and unfortunately some got in when we brought pots inside. After trying many products, this finally did the trick. It is extremely rare that we see any type of bug alive in the house or garage now.
Review by Ann / (Posted on 2/4/2015)
Excellent Product
Received product in 2 days and Cyper WSP was very easy to use with great directions on how to safely use the product. Got rid of all the crickets in one day.

Same Results
I see the same results from this as Demon
Review by PestJoe / (Posted on 7/30/2014)
Not sure about results
Used this product 3 1/2 weeks ago around baseboards sinks cabinets and even outside windows and doors. So far have seen over 10 new scorpions alive and only 1 dead. My guess is they could be coming down from the attic so will set poison up there next. Thats where boxes and clutter sit anyway so we'll try it and see
