Insectifuge

An insectifuge is a substance that repels or drives away insects. It is usually used in the form of a spray or lotion and is often used to prevent insect bites. It works by creating an unpleasant smell or taste that insects find unappealing, thus driving them away. Some insectifuges contain chemicals, such as DEET, which are toxic to insects, while others use natural ingredients, such as essential oils, to repel insects. The effectiveness of an insectifuge depends on the particular ingredients used and the amount of coverage it provides.
