This is an insect repellent made from natural ingredients. With pyrethrum extract as an active ingredient, it works against mosquitoes, flies, fly larvae (maggots), cockroaches, fleas, bed bugs and dust mites. Pyrethrum is a plant familiar to Japanese people as it has long been used as a raw material to make mosquito repellent coils. Other ingredients include eucalyptus oil and lemon scented tea tree oil. As it is made with 100% natural ingredients, it can be safely sprayed around baby beds, sofas, tables, futon mattresses and pillows as well as around the kitchen, pets and houseplants.
