Significance of Repellents
Repellents are effective and safe in preventing diseases caused by insects. These compounds can keep bugs such as gnats, mosquitoes, and ticks away. Mosquitoes are known to be the most merciless insect predators. They fly around and then suck blood from people and animals, like tiny vampires. Mosquitoes can lead to the spread of encephalitis, West Nile virus, Dengue fever, and malaria. Ticks, on the other hand, cause Lyme disease.
Insect repellents prevent insect bites, rashes, and skin eruptions. Severe levels of allergic reaction usually happen because of the mosquito’s saliva during the bite. Because of this, the Center for Disease Control recommends the use insect repellents to keep mosquitoes away.
Humans attract all species of mosquitoes and other insects that suck blood. The carbon dioxide in their skin odors and breath draw them in. A repellent is applied to the skin area. It is effective on the skin’s surface and the area close to it. A repellent always has an active ingredient that makes you unappealing to insects such as mosquitoes. It does not kill the insect at all. If the repellent’s active ingredient concentration is high, then it can provide longer-lasting insect protection.
Make sure that you follow instructions carefully when you read the package of the insect repellent you bought. If you plan to return indoors for the rest of the day, wash off the repellent from the treated skin area. Use soap and water. Never apply repellent directly straight on your face. You should spray the repellent on your hands first before you spread it on your facial skin, around your mouth and eyes.
Do your homework and choose the repellent that can protect you for as long as you are outside of the house. Take note that swimming and sweating can reduce the effectiveness of the repellent. You should re-apply as needed. Avoid applying your repellent on children’s hands because they always use their hands for eating. Do not allow kids to apply the repellent by themselves. Always apply it on your hands first before applying it on their sensitive skin. Do not apply repellents on irritated or wounded skin.
If you want your clothes treated, consider permethrin and DEET. Just be sure not to apply permethrin on your skin.
Repellent Side Effects

This would mean more unnecessary exposure to repellent. When you are exposed to repellents too much, you can experience toxic side effects.
Repellents and Children
There are certain age limits for repellents. If there isn’t any on the product you chose, then you can use it on a child at any age range.

- DEET is not DDT. DDT was banned in the United States in 1972.
- DEET’s concentration indicates the length of protection. A product with 2% DEET can protect for up to about 2 hours, while a product with 98.25% DEET can repel for up to about 10 hours.
Picaridin is a repellent against chiggers, ticks, mosquitoes, and other insects. It was first synthesized during the 1980s. It was formulated to be like piperine, which is an organic compound.

Picaridin exposure can happen through ingestion, skin contact, inhalation, and eye contamination. This ingredient is usually applied on human skin. You may inhale it if you use it around your body, when you are indoors. In here, the vapors linger for longer. It is possible for anyone to swallow picaridin when hands are not washed after handling the repellent. Follow instructions properly and you will reduce your risks in being harmed by picaridin.

In relation to cancer, it was found out that picaridin does not cause cancer among animals after applying it on their skin for two years. The US EPA concluded that picaridin does not cause cancer based on the skin exposure studies in mice and rats.
Picaridin and the Environment
Based on the studies made by scientists, picaridin that goes into the wastewater enters treatment plants but not the treated water. Picaridin binds to the soil where bacteria degrade it. Picaridin does not end up in ground water based on its properties and its use.
Unfortunately, picaridin is toxic to fish. It tends to build up in the tissues of some known fish. Green algae in water that has picaridin does not grown well than in water that has no picaridin. This chemical compound is not toxic to birds.
