Sumika Environmental Science Co., Ltd. is launching 'Hiruguard', a tape-type leech repellent.
It will be available sequentially from April 1st at outdoor shops, fishing tackle stores nationwide, and on e-commerce sites such as Rakuten Ichiba and Amazon.
Hiruguard: Suggested retail price 2,178 yen (tax included) Release date: April 1, 2026
Hiruguard is a new type of leech repellent tape that easily blocks leeches from crawling up by simply wrapping it around your feet, such as over boots or socks.
Hiruguard features a special coating treatment on its tape surface that leeches dislike. The moment a leech touches it, it recoils, preventing it from crawling up or breaking through from your feet (leeches inhabiting Japan do not have the ability to fly, so foot protection is effective in preventing them from crawling up and sucking blood).
Hiruguard can be used in various situations where leeches are present, such as hiking (mountain climbing), fishing, camping/barbecuing, and farm work.
Previously, spray-type repellents and saltwater were commonly used for leech countermeasures, but these often resulted in uneven application or required reapplication. Hiruguard is an innovative leech countermeasure product that can be used without worrying about these troublesome drawbacks. It maintains sufficient effectiveness even when exposed to some rain or splashes. Each pack contains a 3-meter roll, in a thin, lightweight, zippered bag package.
The guideline for use is approximately 30-50cm per foot. One 3-meter roll package can be used 3-5 times.
The effect lasts for approximately one week after application*.
*Effectiveness may decrease depending on usage methods such as prolonged or repeated submersion in water. If you feel the effect has diminished, please replace it with a new one.
