Abstract: The current invention concerns an aqueous synergistic solution for promoting non-lethal migration of acarids from their habitat towards a carrier comprising an attractant for the attraction of acarids, wherein said attractant is limonene, one or more attraction enhancers chosen from the group citronellal, linalool, geranyl acetate, caryophyllene, caryophyllene oxide and/or neryl acetate, and an emulsifier, preferably polysorbate. The current invention also concerns a method for attracting and holding acarids, comprising of the steps: providing a sheet having interstices sufficiently large and a thickness sufficiently large to hold acarids; and applying on said sheet the aqueous synergistic solution in a non-lethal dose per area. The synergistic solution promotes migration of acarids from their habitat into said sheet, after which the sheet can be disposed or the acarids removed therefrom.
