What You Need to Know about Picaridin

Picaridin  can repel chiggers, ticks, and mosquitoes. It is a man-made compound, first manufactured during the 1980s. It was created to resemble piperine, which is found in black pepper producing plants. Picaridin has only been made available in the US in 2005.

Picaridin can be applied on your skin to ward off chiggers, ticks, mosquitoes, fleas, and biting flies. These picaridin products are available as wipes, pumps, aerosols, sprays, and liquids. You can choose from about two dozen picaridin products in the US.

How Picaridin Woks

Picaridin does not kill insects. It just repels them, removing their urge to bite. It has properties that block the ability of mosquitoes to sense their prey.  When insects take a whiff of picaridin, they move away from the treated clothes or skin. When you apply picaridin properly, you acquire a barrier that prevents mosquitoes from landing on your skin and eventually biting it as much as they can.

Exposure to Picaridin

Chemical exposure can happen to people in four different ways: eye contact, ingestion, skin contact, and inhalation. As you may already know, Picaridin is applied on your skin. You can also breathe it in when you spray it around your body, especially when you do so indoors.  Washing hands after applying picaridin is important especially before smoking or handling food. If you do not wash your hands after your picaridin repellent application, it is highly likely for you to swallow some of it. Make sure you read and follow instructions and labels carefully.

What if you Get Exposed to Picaridin?

Skin is a common manifestation of picaridin exposure in some people. Even so, it is uncommon for this to happen. Eye irritation can also happen. A study was performed in which rats were fed picaridin. The kidneys of these rats were greatly affected. They also lost weight. When Picaridin was inhaled, it was classified as non-toxic.

In a study made on rats treated topically with picaridin, about sixty percent of picaridin was absorbed. In a study performed on humans, only six percent of picaridin was absorbed through the skin. Picaridin may also be degraded once it is inside your body. Both humans and rats excrete a large percentage of picaridin within an entire day of their exposure to the repellent.




Picaridin as an Alternative to DEET

Picaridin is like DEET when it comes to its effectiveness as a repellent. It does not usually cause skin irritation and it is not taxing to use at all. Picaridin is a derivative of piperidine. It was initially developed by Bayer®. Since 1998, many countries have been using it as Bayrepel®. It is also known as Icaridin, but is marketed as Picaridin. Since 2005, it has been available in the US.

Picaridin is an effective repellent against biting insects like deer ticks, flies, and mosquitoes. Below are some of the common insects that picaridin repels:


  1. Aedes taeniorhynchus (Black Salt Marsh Mosquito)

What Good Do Natural Repellents Give You?

It is a common sight to see people slathering themselves with synthetic insect repellents, whenever they  are in areas outside their home. These harmful substances stay on your skin and may even cause irritation.

Natural repellents repel insects such as those Aedes species of mosquitoes that cause the dreaded Zika virus. They do not kill the pesky intruders. They merely disable their ability to sense their prey, which include humans and their pets. Here are some of the benefits you can acquire from using natural repellents:

  • They actually work better. Natural repellents work better than synthetic ones, such as those with DEET. Soy-based insect repellents provide a longer lasting protection that products with low concentration of DEET.
  • They are not as hazardous as DEET. As you know, DEET (N,N-DIethyl-3-methylbenzamide) is the most widely used repellent against leeches, fleas, ticks, and mosquitoes. Unfortunately, DEET affects your CNS or Central Nervous System. Experts also fear that when this substance interacts with other repellents, its toxicity increases.
  • The AAP (American Academy of Pediatrics) only recommend repellents that have a minute amount of DEET especially when they are going to be used on children. DEET repellents should never be used on children below two months old. If you have children to protect against biting insects, it is best to choose repellents without DEET or just use mosquito nets and protective clothing.
  • They are considered safe to use on sensitive skin. Synthetic substances such as phthalates, parabens, and petroleum irritate the skin. Natural repellents do not cause any kind of irritation.
  • They smell a lot better. These natural repellents can be produced with cinnamon oil, peppermint oil, geranium oil, and other aromatic oils. Your experience in repelling insects becomes more positive and appealing with natural repellents.


Zika and other mosquito-borne diseases should be kept away from your household and work area. Discuss your options with your family doctor about it.
