FRIDAY, May 25, 2018 – Outdoor Enthusiasts: Here are some good news about the tick fight just in time for the Memorial Day weekend and the unofficial summer start.
A New US Government Study Confirms That Insecticide Has Been Treated Clothes that are marketed for the prevention of tick-borne diseases actually defeat the pests.
In laboratory tests of clothing purchased from a manufacturer, researchers found that garments either crashed quickly or made them unable to bite.
The study included three types of ticks that are major carriers of disease in the United States ̵
The clothes were pretreated with permethrin, a synthetic form of an insect-inhibiting compound from the chrysanthemum flower. It is used in insecticide sprays, shampoos and creams to treat lice and scabies.
Several companies are marketing permethrin-treated shirts, pants, socks and other garments to fend off disease-transmitting pests. The new study adds that the garments are actually toxic to ticks, according to lead researcher Lars Eisen of the US Center for Disease Control and Prevention.
"All tested tick species and life stages underwent the hot foot after exposure to permethrin-treated clothing," Eisen said.
This, he explained, caused the ticks to fall off "vertically-oriented" clothing – which was a Also, if the ticks had contact with the clothes for up to five minutes, they would lose their ability to move normally – and bite.
There is still Questions, including which types of clothing provides the best protection in the real world.
The CDC already recommends permethrin as a tactic to prevent tick bites, stating that people 'clothing and equipment such as boots, pants, socks and tents can handle products containing 0.5 percent permethrin. "
The agency says that" pretreated clothing is available and can be longer-lasting. "19659002] Thomas M ather is the director of the Center for Vector-Borne Disease of the University of Rhode Island and its TickEncounter Resource Center.
He said the new findings, published on May 24 in the Journal of Medical Entomology, offer more support for
"This can be a pretty effective way to stem ticks," said Mather, who did not comment the study was involved.
In his own investigation, Mather found that even permethrin-treated summer clothes had advantages that left some skin uncovered – shorts, T-shirts, socks and sneakers.
His team had a group of brave volunteers watching a movie while allowed lab-raised, disease-free ticks to crawl on their bodies. Some wore regular clothing, others wore permethrin clothing – either pre-treated or with the insecticide added with home kits. Those who wore either treated clothes ended up with far fewer live ticks on their bodies at the end of the movie.
While people can use permethrin on their regular dresses, the pre-treated garments hold many more washes, according to Mather – up to 70.
Some people are wary of chemically treated clothes. But Mather said the amount of permethrin in clothing is very low: a solution containing only 0.5 percent of the pesticide is "dried" into the fabric.
According to the US Environmental Protection Agency, research shows that permethrin absorbs "bad" through the skin, and there is no evidence that treated clothing could be harmful to children or pregnant women.
US military personnel have been using permethrin-treated uniforms since the 1990s, EPA notes. According to Mather, the garments can also be a good bet for people whose work keeps them out – or for gardeners or anyone who spends time in places where tick exposure is a concern.
Iron referred to some other CDC-recommended ways to reduce the risk of tick-borne diseases: Avoid wooded areas with tall grass and "leaf litter"; Walk in the center of hiking trails; Use EPA-registered repellents containing ingredients such as DEET, picaridine, or lemon eucalyptus oil; Thoroughly check your body and clothes for ticks after being outside; and take a shower home within two hours.
