Summary:PROBLEM TO BE SOLVED: To obtain the subject excellent which displays medicinal effects for a long term and can be used in various forms and effectively display excellent residual effectiveness by using microcapsules which contain a pyrethroid-based insecticide having a specific core structure. SOLUTION: These microcapsules are composed of a core part formed from a gel-like polyurethane resin 1 containing a pyrethroid insecticide and a shell part formed from a polyurea resin 2. The microcapsules are dispersed into an aqueous medium to obtain a dispersion solution containing a tick expellent. On the dispersion solution, when the dispersion solution contains at least one of a water-soluble polyurethane resin and an aqueous emulsion of synthetic resin as a binder component, the washing-resistant property is improved and the tick-resistant efficiency is more effectively displayed for a long term in a case that the dispersion solution is used for milling of papers and cloths.
