3M Ultrathon Insect Repellent Lotion, 2-Ounce

In numerous studies DEET has been shown to be one of the most effective insect repellents for mosquitoes and ticks. We liked that this lotion was easy to apply, didn’t smell bad and worked well.

DEET has been shown to be one of the most effective insect repellents for mosquitoes and ticks. Some research have indicated that DEET can be dangerous in large doses. However, if the choice is to get bitten and risk the chance of disease or apply a little DEET, we always choose to be protected.

We used this product at the beach in Costa Rica where the mosquitoes were abundant and the bites were painful and swelled alarmingly. We particularly liked how easy it is to apply and that it is long lasting. It was one of the most effective repellents we tried, and also worked on no-see-ums, which were also abundant.

3M Ultrathon insect repellent was developed for the military to provide long lasting, time released protection against mosquitoes for up to 12 hours. Repels Ticks that may carry West Nile Virus and also mosquitoes, biting flies, chiggers, gnats, fleas and deer flies. Splash & Sweat Resistant.

Unique 3M Polymer Technology optimized to enhance the efficacy of DEET and provide time controlled release of DEET. Stable in Freeze/Thaw conditions. 5 year guarantee. Consistently rated as a top insect repellent by independent testing labs. Tested in the harshest conditions of South America.

Works longer with less DEET. Competitive products are alcohol based and when the alcohol evaporates you lose your protection. Ultrathon uses the time released technology to provide a longer lasting repellent.

Used in Thailand in the middle of summer. Worked great. I went to Thailand and was terrified of mosquitoes, since my friends said they got eaten up by them. I used this product and I didn’t get bit anywhere, except where I didn’t apply, like my face, ears, and behind my knees and elbows. It worked great wherever it was applied. My friend who used Off spray got bit even if he used the product. The product does leave a slight waxy film on you after application, but it seems that all deet products leave some film and it’s something you have to get used to if you want to protect yourself from mosquito bites. I get welts from mosquito bites and would rather tolerate the waxy feel than the bites.

Alright…. So we had just taken a trip to the Peruvian Amazon Rainforest and needless to say there were a lot of mosquitoes there. The stuff works as long as you dont sweat. As soon as you start sweating the deet stops working. But thats the case with any Deet product. This stuff is greasy and i put it on my face and surprisingly I didnt break out from it. However I would get this and also make sure to get a permethrin clothes spray as well bc the mosquitoes will go through all clothing and sit there too! I think this stuff works well just like any other deet product but just make sure u also get the spray for your clothes as well!
