Title: Control of allergy-causing mites -  particularly in carpets, furniture and mattresses, comprises saturating habitat with menthol vapour
Inventor: WOLF JOACHIM DIPL ING
IPC: A01N31/06
Filed: 1991-05-08
Abstract: Control of allergy-causing mites by permeating the site of the infestation with an amount of menthol (I) sufficient to kill the mites is new. An acaricidal compsn. for the above use contg. (I) and a solid or liquid carrier is also claimed. (I) pref. is (-)-menthol and is used esp. in a concn. of 5-50 mg/l of infested area. (I) pref. is used either as solid absorbed on a carrier or as an aerosol. E.g. strips of paper, cardboard or textile can be immersed in melted (I) and, after cooling, the impregnated strips can be placed at the site to be treated. Alternatively shredded paper, silica gel, pwodered cellulose or sawdust can be impregnated with (I) and then e.g. scattered over carpets. De-infestation of mattresses is suitably carried out by placing a blanket which has been soaked in (I) or a cardboard sheet coated with (I) on the bed. In the treatment of mattresses and carpets it can be advantageous finally to cover the area being treated with a plastic sheet in order to keep the vapour of (I) close to the site, to reduce the total amt. of (I) required and, in the case of mattresses to guarantee treatment of the entire bed.
