Borate is a non-volatile substance, so its effect lasts semi-permanently.
As it is highly water-soluble, if the sheet is submerged in water for a long time, the borate will leach out of the sheet and its effectiveness will decrease. Please be aware of this.


★ Active Ingredient is Borate ★
When borate is absorbed into cells, it inhibits cell metabolism.
Mammals and other organisms with kidneys can excrete borate from their bodies, but organisms without kidney function cannot, thus the effect is achieved.

★ Long-lasting Effect! ★
Borate diffuses into the surroundings with moisture.
Furthermore, as it is non-volatile, it remains in place for a long time.
*When replacing tatami mats, we recommend replacing the insect repellent sheets as well.

★ High Safety ★
Does not contain substances that cause sick house syndrome.
The acute toxicity of borate is at the same level as table salt, making it highly safe.
