Repellent - Kihizai

Japanese: 忌避剤 - きひざい
Repellent - Kihizai

A drug used to keep unwanted insects and animals away, also called a repellent. Diethylamide di-N-propyl isocinchomeronate, 2,3,4,5-bis( Δ 2-butylene)tetrahydrofurfural, di-n-propyl isocinchomeronate, and N-octyl-bicycloheptene dicarboximide are some of the drugs used to prevent bites from insects such as mosquitoes, horseflies, blackflies, fleas, bedbugs, mites, and stable flies, and sprays, lotions, and creams containing these are available commercially. They are applied or sprayed on exposed areas of the skin, such as the face, neck, arms, and legs. They can also be applied by soaking them into the inside of clothing sleeves and hems.

Repellents for mice and rabbits include β-naphthol and cycloheximide. These act as taste repellents and are only effective when a mouse or rabbit bites them. They are effective on electric wires, gas hoses, furniture, etc., but are not effective on places that are simply used as passageways. Sprays containing 0.2% cycloheximide are commercially available.
