Point estimates and 95% Wilson scores for the proportion of Ixodes scapularis nymphs repelled at each timepoint (0.5–6.5 h) after application for the 11 formulated 25(b) exempt repellent products labeled for ticks (A–K). Timepoints with an asterisk indicate that no significant difference was detected between the effectiveness of that product and the two DEET-based products (25% concentration) tested at that time point according to the post hoc Tukey tests. The active ingredients with the highest concentrations in each product were: Product A (cedarwood oil: 4.2%), Product B (cedarwood oil: 4.2%), Product C (cedarwood oil: 4.2%), Product D (cedarwood oil: 5.7%), Product E (geraniol: 4.75%), Product F (soybean oil: 5.2%), Product G (castor oil: 8%), Product H (corn oil: 20%), Product I (cedarwood oil: 3.65%), Product J (cedarwood oil: 10%), Product K (clove oil: 2%)
