摘要

repellent composition for hematophagous arthropods, porous vehicle and repellent discharge apparatus. The present invention relates to a repellent composition for hematophagous arthropods. The repellent composition comprises vanillin and one or two types of essential oils selected from the group consisting of cinnamomum cassia, rosmarinus officinalis, eucalyptus citriodora, cymbopogon citratus, xanthoxylum armatum, and cimbopogon nardus. thus repellency to hematophagous arthropods is improved and repel duration time is increased. Additionally, the invention relates to a porous carrier containing the repellent composition for hematophagous arthropods, and to a repellent generation apparatus.
