hyönteiskarkotin

Hyönteiskarkotin, commonly known as insect repellent, is a substance or device designed to deter insects, particularly biting or nuisance species. These repellents work through various mechanisms, often by emitting a scent or chemical that insects find unpleasant or by masking the human scent that attracts them.

The most common active ingredients in topical insect repellents include DEET (N,N-diethyl-meta-toluamide), Picaridin (also known as Icaridin or KBR 3023), and oil of lemon eucalyptus (para-menthane-3,8-diol or PMD). These are applied to exposed skin or clothing to provide a barrier against insect bites. Different repellents have varying durations of effectiveness and target specific types of insects.

Beyond topical applications, other forms of hyönteiskarkotin exist. These include citronella candles and coils, which release a repellent smoke, and ultrasonic devices that emit high-frequency sounds claimed to repel insects, though their efficacy is often debated. Mosquito nets and screens also act as physical barriers, preventing insects from reaching humans.

The primary purpose of insect repellents is to protect against insect-borne diseases such as malaria, West Nile virus, Zika virus, and Lyme disease, in addition to preventing the discomfort and irritation caused by bites. When selecting and using an insect repellent, it is important to follow the product's instructions for safe and effective application, paying attention to age restrictions and potential skin sensitivities.
