A mosquito repellent is a substance applied to skin, clothing, or other surfaces which discourages mosquitoes (and arthropods in general) from landing or climbing on that surface. There is also Mosquito repellent products available based on sound production, particularly ultrasound (inaudibly high frequency sounds). These electronic devices have been shown to have no effect as a mosquito repellent by studies done by the EPA and many universities.

A liquid Mosquito repellent is a kind of a liquid which is applied to skin which helps to discourage mosquitoes. liquid mosquito repellents help prevent and control the outbreak of Mosquito-borne diseases such as malaria, Lyme disease, Dengue fever, bubonic plague, and West Nile fever. Pest animals commonly serving as vectors for disease include the mosquito’s flea, fly, and mosquito; and the arachnid tick.

The first truly effective active ingredient used in liquid mosquito repellents was citronella oil. This material is an herbal extract derived from the citronella plant, an Asian grass. While citronella had been used for centuries for medicinal purposes, its repellence was only accidentally discovered in 1901, when it was used as a hairdressing fragrance. Since citronella oil is a fragrant material, it is thought that the chemical terpenes of which it is composed are responsible for its repellent activity. Citronella oil does repel mosquitoes, but it has certain characteristics which limit its effectiveness. For example, it is very volatile and evaporates too quickly from surfaces to which it is applied. Also, large amounts are needed to be effective.

Mosquito repellent safety:
Regarding safety with Mosquito repellent use on children and pregnant women:

• Children may be at greater risk for adverse reactions to repellents, in part, because their exposure may be greater.
• Keep repellents out of the reach of children.
• Do not allow children to apply repellents to them.
• Use only small amounts of repellent on children.
• Do not apply repellents to the hands of young children because this may result in accidental eye contact or ingestion.
• Try to reduce the use of repellents by dressing children in long sleeves and long pants tucked into boots or socks whenever possible. Use netting over strollers, playpens, etc.
• As with chemical exposures in general, pregnant women should take care to avoid exposures to repellents when practical, as the fetus may be vulnerable.

Regardless of which repellent product used, it is recommended to read the label before use and carefully follow directions.[13] Usage instructions for repellents vary from country to country. Some Liquid mosquito repellents are not recommended for use on younger children.
