Abstract Acantholippia seriphioides, Artemisia mendozana, Baccharis grisebachii, Gymnophyton polycephalum, Satureja parvifolia, Tagetes mendocina and Lippia integrifolia essential oils obtained by hydrodistillation, were analyzed by GC–FID and GC–MS. Its bioactive potential as antimicrobial, antioxidant and repellent agents were determined. The highest number of components (40) was identified in L. integrifolia essential oil, which, along with that of A. seriphiodes, contains important amounts of oxygenated monoterpenes (44.35–29.72% respectively). Strain standardized and clinical dermatophytes Microsporum gypseum, Trichophyton mentagrophytes and T. rubrum were inhibited by G. polycephalum, L. integrifolia and Satureja parvifolia essential oils (MIC between 31.2 and 1000 µg/mL). The essential oils showed moderate antibacterial and antioxidant activity in DPPH and FRAP assays, and excellent repellent properties (62.6 to 100%) against Triatoma infestans, Chagas’ disease vector
