I use this on every hike I take in New England during the mosquito season.
I find it the most effective of all the sprays and it lasts.
Use sparingly on the skin and watch out for plastics as it can damage them.
The SRA-6 spray is 25% DEET (zoom in on the image and you can read the content) and not 0.5% Permethrin as stated in the product description.

We have used this product for years. We live in northerm Mn and this has been the only thing we found that protects us. We have not been able to find it in any stores this year so I decided to check on line and found that Amazon carried it at the best price.

We live next to a river, 2 ponds and a swamp. Needless to say it gets really buggy here. We have tried all the sprays out there and ultrathon is the best. Also, if you research you will find that ultrathon is the only deet repellent that will not be absorbed by the blood stream. Great product, you won't be disappointed

I have used Ultrathon for YEARS. Developed for the Military it works. I live in Texas and on the Gulf coast we have mosquitos with West Nile and those that are HUGE too. "Off" should be called "ON" since it is useless and actually seems to attract bugs. Read the warning label on Ultrathon, do what it says and you should be fine. Ultrathon is water resistant and works for hours.

I'm really not sure how to rate this product so I put 3 stars down. I ordered Ultrathon for our recent trip to Costa Rica based on the reviews on Amazon. What I ordered from Amazon was a couple of bottles of an aerosol like the photo shows but the bottles I got, aren't what is advertised on the photo. I received bottles with those nozzles like the aerosols for Coppertone sunscreens or Banana Boat suncreens etc. I ordered this Ultrathon because I didn't want to deal with the clogging issues that the design of the spray bottles like the aforementioned brands have. Unfortunately, I didn't have time to send the Ultrathon back and get more so I just took the bottles of Ultrathon to Costa Rica that were sent to me plus 2 bottles of Sawyer brand repellent that I had at home. While on vacation my family and I sprayed frequently to avoid the mosquitoes in Costa Rica but getting the spray out of the can proved to be quite difficult. The nozzle or whatever creates the spray gets so clogged that it actually hurt my thumbs and fingers to use the bottle because you have to press SOOOOOO hard to get it to work. Even my husband couldn't make it work half the time. Ultrathon did work when we used it but it took ALOT of effort to use the product and a lot of the product in the bottles was wasted because we had to leave some of the bottles half full since we couldn't get the product out. You may think I'm exaggerating but i'm serious when I say that we literally couldn't push the spray button down. We thought that maybe it was just bad luck that the first can gave us so much trouble but it turned out that all the cans we took had the same issue. Needless to say we ended up using the Sawyer brand repellent I brought along as a back up and the spray bottle was easy to use and let out a fine mist that provided excellent coverage. The only reason we repeatedly tried using the Ultrathon for whatever spray came out was because I didn't have enough of the Sawyer brand to cover us for the length of our trip and buying bug spray in Costa Rica is very expensive and all I saw was the "OFF" brand over there. Again I wasn't sure how to rate this product because it did work when we could get it out but for all the trouble we had using it, I think next time I would just buy more of the Sawyer brand product from out local Dicks Sporting Goods Store because at $4 a bottle, it worked just as well as the Ultrathon and I didn't have any difficulty using it. Please note that Sawyer has 30% deet and even though my family tries to avoid using chemicals, we didn't mind using the higher percentage deet on this particular trip because a few of us ended up with giant size mosquito bites when we missed a spraying.

Great stuff. WORKS MUCH BETTER THAN OTHER BRANDS.
We hang out on our Sailboat a good bit on the river and the "No See-ums", or Knats, are atrocious.
They will ruin a great evening aboard the boat or around the water.
However,using this product I found that they are way more manageable and I no
longer "head for safety", once they begin there miserable assault on our lives.
I have to re-apply every so often.....but hey, it works better than ANYTHING ELSE out there...
I have tried them all....this is the best stuff available..., and it's not sticky or greasy...

I live know in west Mexico and sometimes Mosquitos are very tuff and resilient to "natural" repelents that includes ingredients like citric oils or citronella.

Ultraton always work very well for me up to 4 hours after each application

The spray nozzle that came with this repellant did not work at all. I substituted another nozzle from a can of spray paint - that worked, but the can did not come with a cap, so I must pack the repellant without a cap

This is great stuff. It isn't as nice smelling as some other products, but not offensive either. It is very effective in keeping the mosquitoes at bay. Additionally, when the chiggers lurking around in full force, an application on the shoes, ankles and lower extremities allows one to enjoy the freedom of being outside without getting nailed by dozens of the critters. Long lasting, doesn't sweat off while working outdoors, all the while while doing so with a lower DEET content than many of the other products. The down side is that Ultrathon isn't readily available on the shelf, so one needs to plan ahead to prevent being without this great protection from the airborne pests.
