Permethrin vs Oil of Lemon Eucalyptus

The world is now fully aware of what Zika can do. The scare has caused many people to be more careful about their travels and their Zika prevention methods. Since the primary transmission of Zika is through mosquito bites, you should always be sure that you keep mosquitoes away from you and your loved ones.



How to Prevent Mosquito Bites

The female Aedes species of mosquitoes are the ones that need to bite so that they could acquire the blood they need for their eggs. To keep them away, here are some tips:

  • Get rid of the things that store stagnant water in and around your home (old pails. Bottles, old tires, etc.)
  • Light up mosquito coils
  • Use mosquito netting during bedtime
  • Keep your area clean
  • Wear long pants and long sleeved shirts
  • Use mosquito repellents

Why Use Natural Repellents Against Mosquitoes?

Have you ever wondered why you are encouraged to use natural mosquito repellents? Here are some of the reasons:

  1. Most of them work better. Studies have shown that natural mosquito repellents are equally or even more effective than repellents that have DEET. Soy-based repellents offer longer protection than products with low-concentration of DEET. Mosquito repellents that contain oil of lemon eucalyptus are better at deterring products with DEET. They are also effective in keeping ticks away.
  2. They do not have DEET. DEET (N,N-Diethyl-3-methylbenzamide) is the most widely used active ingredient in making insect repellents. It helps give you ample protection against ticks, leeches, fleas, and mosquitoes. Even if DEET is truly effective, it is known to affect your nervous system. Some also fear that it may interact with chemicals from certain repellents. These could make DEET to become more toxic.
  3. They are good for your body.  These natural repellents are also beneficial to your body. One example is peppermint oil, which energizes and improves your concentration. It also relaxes your muscles when you apply it on your skin.
  4. They are not harmful to skin. Many repellents have synthetic materials such as petroleum, phthalates, and parabens. These usually irritate people who have sensitive skin or who suffer from allergies. Natural mosquito repellents are free from such chemical compounds. That is why people enjoy being mosquito-free without dealing with negative adverse effects.
  5. Some of them have been developed by licensed doctors. Doctors know and understand the impact that ingredients of repellents have on your body. They want to make sure that their repellents help maintain optimal health while fighting off unwanted biting insects.
  6. They smell better. It is no secret that many insect repellents smell unpleasant. The unsavory smell is a downer on your camping trip or cookouts. Natural repellents are derived from essential oils (cinnamon oil, peppermint oil, or geranium oil). They smell a lot better. Their fragrances entice repellent users more.


Need-To-Know Info about Permethrin

Basically, permethrin is the synthesized form of pyrethrum (a natural insecticide that is obtained from Chrysanthemums). It is used in different dosages for lice treatments in humans, agricultural purposes, and repelling insects. Permethrin repels biting insects such as ticks and mosquitoes. If you want to use it as a repellent, you just have to apply it on your clothes and not on your skin.

Permethrin is known as an effective and safe mosquito repellent. There have been tests performed on lightweight uniforms that were treated until they were moist. About 4.5 ounces of 0.5% Permethrin provided 97.7% protection from mosquitoes.

This effective product was developed for clothing. It bonds well to clothes so well that it stays repellent to biting insects. The effectiveness of permethrin on clothes is about five to twenty washings or two weeks to six months.

Permethrin Safety

Some people reported mild irritation of the skin when they used permethrin treated clothes. There are no lasting effects reported from using permethrin. Because it is biodegradable, it binds easily to clothing and soil. In just one to sixteen weeks, it breaks down completely. It is not toxic to mammals and birds at all, but it is to fish, bees, and other insects. It is crucial that the permethrin residue does not contaminate aquatic environments or crops.

p18Applying Permethrin

Below are some pointers in applying permethrin to some items:

  • Select your clothing pieces (socks, shirts, pants or shorts).
  • Spread the items on a surface and prepare your spray can of permethrin.
  • Hold the spray can about a foot away from the clothes.
  • Use sweeping motions in spraying permethrin on the clothes.
  • Spray more on collars and cuffs.
  • Repeat the process when you turn the clothes over.
  • Hang the clothes and allow them to dry thoroughly.
  • You can place the treated clothes in resealable plastic bags until you are ready to use them.
  • If you want to treat mosquito nets, repeat the process you did for your clothes.

Using Permethrin and Another Insect Repellent

You can definitely use permethrin with other insect repellents such as picaridin or DEET (N,N—diethyl-meta toluamide). Remember that DEET or picaridin can be applied on your skin and permethrin is for your clothes. With this much protection, you are sure to avoid the any illness brought about by mosquito bites.

Why Permethrin is Prescribed

Permethrin is generally used to treat scabies in children (at least 2 months old) and adults. The over-the-counter (OTC) permethrin is used to treat live in children (at least 2 months old) and adults. Permethrin products are classified as pediculicides and scabicides. They kill mites and lice.

Using Permethrin

Below are some of the steps to remember in applying permethrin:

Permethrin Cream

  • Rub a thin layer of permethrin cream from your neck to your toes (do not forget the soles, skin folds, waist, and buttocks).
  • This cream should be applied on the forehead, temples, hairline, or scalp of adults above 65 years old and babies.
  • You may need to use the entire tube.
  • Leave the permethrin cream on your skin for about eight to fourteen hours.
  • Wash off the cream by showering or soaking in the tub.
  • Take note that you may feel some itchiness after your treatment. This does not mean that your treatment has not worked. Just check with your doctor to see if there are still live mites at least fourteen days after the treatment. The process needs to be repeated.

Permethrin Lotion

  • Wash your hair first and then rinse it with water. Refrain from using a shampoo with condition or a conditioner. These products do not allow the permethrin treatment to work well.
  • Dry your hair well until it is damp.
  • Shake the bottle of permethrin lotion so that the medication is mixed evenly.
  • Get a towel and use it to cover your eyes and face. Keep your eyes closed during the treatment. You may need another person to apply the lotion.
  • Use permethrin to your scalp and hair. Apply the lotion behind your neck and behind your ears.
  • Leave the lotion on your scalp and hair for ten minutes. A timer would be helpful.
  • Rinse your scalp and hair with warm water, preferably in a sink. Do not rinse it in your tub or in your shower because the lotion should not get all over your body.
  • Dry your hair and smooth it out with a comb.
  • Wash your hands properly. This includes anyone who helped you.
  • Use a lice comb to remove the dead nits (empty shells of lice eggs) and lice.
  • After seven days, check your head again. If you see live lice, repeat the process.
  • Sanitize your towels, clothing, underwear, sheets, pajamas, hats, and pillowcases. Use hot water or send them to the dry cleaners. Wash hair clips, combs, brushes and other items you use for personal care in hot water.
