If you want to protect yourself from mosquitoes and ticks – you It seems to be everywhere This year-you may need to recruit heavy multiplication. Insect experts reach one thing: Permithrin.
Here is what to know about artificial pesticides, as well as how to use it and when.
How does Permithrin work
Bermethrin, derived from the Chrysanthemum flower, has been used in some form. About 400 BC. During the wars of the early nineteenth century, Napoleon’s dust of his soldiers with a pyramithrin -like powder To control fleas and body lice, which he protects them from anemia and gave them a material advantage over their enemies.
Permithrine is the nervous poison that targets the nervous system of the insect, which leads to muscle spasms, paralysis and death at the end. It works as a touched insecticide, which means that it is killed by direct contact when the defect lands on a processing surface. What distinguishes it from Repentance on DeetThat works differently. “It prevents the insect sensors to find you, so you end up with a cloak of secret.” “They are attracted to your heat, but they cannot find you.”
To visualize how Piermithrine works, think about what will happen if you eat something but cotton candy for a week. “Can you imagine how excessive activity?” Henz asks. The same thing happens to the mistakes: “If you see mosquitoes that touch Permethrin, this is vibrating in an irreplaceable way, as it fly irreplaceable, just as he had a lot of sugar. That causes muscle spasms. Once the insect muscles are exhausted, they become paralyzed and then die.
If this seems unpleasant, then it is. “It is not a nice way to die,” says Heins.

She adds that the scent and non -color pymermeine, and insects cannot discover their existence. This helps to make it effective. In one Ticket Among the Iranian army members, for example, the average number of mosquito bites in those who wear an inverted uniform was 108 per hour, compared to 10 an hour in soldiers wearing the outfit of Permithrin defects.
During, I found research People who were wearing socks and sneakers treated in Permithrin have been 74 times less likely to get a mark bite than those who wear unspecified shoes. The study participants who were wearing short pants and shirts that were treated with Bermethrin were about 5 and 2 times less, respectively, to get more ticks than those who were free of Permithrin. The researchers wrote that the results highlight “the capabilities of summer clothing that were treated in Berr -Tatherrin to significantly reduce tick bites and transfer the pathogenic factors that the tick transfers.”
DIY for pre -treated clothes
How to apply Permithrine issues. If you want to go to the DIY path, choose a product with a 0.5 % Permatrin concentration. You can either buy a pre -spray bottle, or reduce a focused jug for yourself.
You can Permithrin spray on your clothesAccessories, equipment – not your skin. People often spray their pants, shirts, socks, shoes, hats, jackets and dire backpacks, for example. (It does not harm the clothes.) You usually need to be applied from 24 to 48 hours before the exit; In this way, it has time to dry and connect the material you sprayed. Spray your clothes outside and while you are outside your body; Hold it on the laundry rope, for example, and sprinkle it evenly so that it becomes wet but not dripping wet.
Bobby Brett, a professor of laboratory medicine and pathology and head of the clinical microbiology department in Mayo Clinic, always sprinkles with her equipment abroad on the balcony of her screen, which has been well activated. Keep in mind that the liquid shape can be toxic to cats, although it is safe as soon as it dries. At this stage, “You don’t have to worry about the presence of a cat in your lap,” says Brett, who runs the blog Wonderful crawling parasites.

If you choose to spray the pymithrin on your clothes and equipment, you will need to follow when doing this. Most products last up to six weeks or six washing machines – whatever it could be redesigned. This is one of the reasons why some people prefer a long -term long -term clothing, which is sold in outdoor lime stores and can generally last up to 70 wash. It is the only insect repellent used to treat the factory for clothes, According to the US Environmental Protection AgencyAnd the risk evaluation procedures at the Environmental Protection Agency “showed that the clothes treated at the Bermethrin factory are unlikely to pose any immediate or long -term risk in the long run for people who wear clothes,” according to their website.
HaINES recommends choosing pre -treated clothes instead of Permethrin application yourself. “It is better to get factory clothes,” she says. “It is long -term, and they had to test it to make sure it is working.” In addition, it is constantly applied and removes the possibility of a human error from the non -missing spray technology. It also removes the need for advanced preparation: people sometimes forget the Permethrin applicable to their clothes before needing, but with pre -treated clothes, you can take and go.
What about natural errors sprays?
Permethrin It is safe When using it as directed. Research indicates this Less than 2 % Insecticides are absorbed through the skin when they are applied to clothes, and Environmental Protection Agency notes There are no known risks from Permethrin for pregnant women or nursing. It’s too Safe Those over two months old. “From all the studies and data we have, they are somewhat safe as long as you use it according to the instructions mentioned in the specified brand container that you have,” says Brett.
However, some people prefer natural options. Henz says there are a number of candidates: the eucalyptus lemon oil can be applied to the exposed skin as well as clothes and works well to repel mosquitoes and ticks. Be sure to get one with a concentration from 30 % to 40 %, and dilute it with water before use. “It has a very strong smell, and you have to re -apply it every two to three hours, but it works,” she says. Tea tree oil, which also needs to be diluted, is an other common natural insect repellent. According to Haines, which keeps insects away, but you have to re -apply them repeatedly like eucalyptus lemon oil.
“What I am trying to tell him is, yes, there are alternatives, but you have to use it responsibly if you want to protect yourself,” she says. “The natural answer is not as good as the answer is modified by the chemist to be higher effective.”
Permemithrine made part of your routine
Brett at Bermethrin thinks that “one piece of the puzzle – one tool in your tool box to protect yourself from ticks and mosquitoes.” When she goes out in the field to conduct research, she raises her pants in her socks and wears long shoes. She sprays her entire clothes with Birmethrin the night before, so she is ready the next morning. It also sprinkles insect repellent on any exposed skin – she often chooses lemon oil from eucalyptus, which was found well for her.

Henz takes a similar approach, but spray a repellent with 20 % picardine on her open skin. “It is really fatal on tick,” she says. “It works on Midges and mosquitoes – it works on everything.” In addition, it usually lasts for eight to 12 hours. She adds that she does not have a strong smell, and she is not oily. Get your pair with burents, and it will be more protection than the blood that provokes blood.
