3M Ultrathon™ insect repellent FAQ’s

  • Biting insects have antennae that detect lactic acid, carbon dioxide, and other volatile compounds that humans and animals give off in their breath and from their skin. Mosquitoes are so sensitive to these chemicals that they can detect a potential blood meal from as far away as 100 feet! Insect repellents are believed to work by blocking the stimulation of these receptors, preventing insects from homing in on their source.

  • DEET has been used by the U.S. public since 1957. Despite 40 years of testing more than 20,000 other compounds since then, DEET remains the most-effective and broad-spectrum repellent currently available.

  • There is no one right answer to this question. The various concentrations of DEET are out there to address different needs. As a general rule, higher concentrations of DEET will offer longer-lasting protection, but this effect tends to level out at concentrations of DEET over 50%. Under most circumstances of casual use, 10% - 35% DEET will provide adequate protection. However, there are certain conditions in which using a higher concentration of DEET may be preferable. These circumstances include the following:

    • Conditions in which there is a rapid loss of repellent to the skin due to washoff from rain, perspiration, or high ambient temperatures

    • When traveling to an area where there is a very high density of biting insects (e.g., the Everglades or Alaska)

    • When traveling to areas where insect bites can transmit serious diseases to humans (e.g., malaria, yellow fever, filariasis, viral encephalitus, etc.)

  • Insect repellent should be applied as a thin layer, covering all the exposed skin surface evenly. There is no need to saturate the skin in order for the repellent to be effective. Do not apply insect repellent over cuts, wounds, or inflamed or eczematous skin.

  • DEET can be applied to either exposed skin or clothing. It should not be applied to skin that is covered by clothes. DEET should also not be applied to synthetic fabrics such as rayon or to plastics, because it can damage these products.

  • DEET essentially only protects the areas to which it is applied. Its repellent effect cannot travel far. The application of DEET to a few points of the body, therefore, will not "cloak" the user in protection. All exposed skin must be treated with DEET in order for it to be protected. Hungry insects will readily find any areas of unprotected skin.

  • Nearly all DEET-based repellents on the market contain the DEET chemical simply mixed in a base of lotion, or alcohol. Extended or controlled-released products, in contrast, package the DEET in a special base that allows it to be released more slowly on to the skin surface. There are several advantages to this technology: These products will give longer-lasting protection, without requiring the use of high concentrations of DEET. They also reduce the number of times that re-application of the product may be necessary, and potentially lower percutaneous absorbtion. Only two products are presently available that use slow-release technology: 1) Ultrathon and 2) Sawyer's Controlled Release. Ultrathon contains 33% DEET in a polymer base; it is identical to the repellent used by the U.S. military.

  • When traveling to areas of the world where insect-transmitted diseases such as malaria, yellow fever and viral encephalitis are common, proper application of insect repellent is crucial to prevent the possibility of being infected. A DEET-based repellent will offer the best insurance against being bitten. Controlled-release DEET products may well be the ideal choice for the traveler looking for long-lasting protection without having to resort to using repellents with DEET concentrations over 35%. In general, citronella-based repellents would not be predicted to provide adequate protection when traveling to these areas.

  • Although it is true that there have been rare reports of seizures and neurological side effects associated with DEET use, it is important to realize how rare these reports are. The U.S. EPA estimates that 200 million people use DEET repellent every year. After more than eight billion applications of DEET worldwide, there have been only 21 cases reported in the medical literature in which the use of DEET seemed to have been associated with the development of neurological toxicity. Six of these cases were a direct result of deliberate ingestion. Twelve of these 21 cases resolved completely, without any residual effects. When the EPA reviewed all available DEET human and animal neurotoxicity data in 1998, they concluded there was no evidence that DEET was a selective neurotoxin. Even if all the reported cases of neurological toxicity ascribed to DEET use were confirmed, the real-life risk of neurological side effects from DEET would be less than 1 in 100 million users.

  • In a nutshell, yes. In 1998, the EPA released all the available safety data on DEET and concluded that there was no evidence that DEET posed any greater risks in the pediatric population. Reports of toxicity in the medical literature did not correlate with the age of the applicant. The American Academy of Pediatrics has recently revised its recommended use of DEET on children. Although the Academy previously recommended that DEET concentrations in insect repellents used on children not exceed 10%, the Academy now recommends using "products with concentrations around 30% for adults and children. Products with lower concentrations (10% to 15%) can be used for children, if families are concerned about the potential risks of DEET and there is little or no concern about the transmission of malaria, encephalitis or other major vector-borne diseases."

  • Sunscreens and insect repellents may be used together on exposed skin. However, there is some evidence that DEET can reduce the efficacy of sunscreen when applied to the same area. One study showed as much as a 33% decrease in sun protection (SPF) when a 33% DEET lotion was simultaneously applied. Therefore, when applying both DEET repellent and a sunscreen, you will need to reapply the sunscreen more frequently to prevent sunburning.

  • Currently available "natural" or "plant-based" insect repellents cannot match the broad-spectrum efficacy and long-lasting action of DEET repellents. Most natural repellents contain citronella, which is a lemony-scented oil derived from two cultivated grasses. Very variable efficacy has been reported in scientific studies of citronella, depending on the product tested and the species of insect examined. In general, these studies show very short protection times, lasting just a few minutes to up to two hours. Of the available plant-based repellents, Blocker™ (available in the United States since 1997) seems to be the most effective. This repellent contains soybean oil in a base of coconut and geranium oils and has been shown to work against certain species of mosquitoes for as long as eight hours.

  • Densely woven or mesh clothing can reduce the likelihood of being bitten. As a sole method of protection, however, physical barriers have their drawbacks, including that they tend to be hot, limit mobility and visibility, and will not be effective in any area of the body where twisting or bending brings the fabric in direct contact with the skin surface, making it possible for an insect to bite through the fabric.
