[PROBLEMS] To provide a microorganism control performance, particularly an antibacterial performance, an algae control performance and a biofilm formation suppression performance, and a microbial control agent in which metal elution is suppressed, and an ability to suppress the occurrence and increase of mites, Provided are an acaricidal composition, an acaricidal component and an acaricidal method. The microorganism control agent of the present invention contains platinum particles and metal particles other than platinum. Moreover, as for the said microorganisms control agent, the said platinum particle and the said metal particle may be carry | supported on the base material. The above-mentioned microorganism control agent is excellent in antibacterial performance and also suppresses metal elution. The acaricidal composition of the present invention contains platinum particles and metal particles other than platinum. The said acaricidal composition is excellent in the performance which suppresses generation | occurrence | production and increase of a tick. [Selection figure] None |
