Ticks are a significant health concern, as they can transmit diseases like Lyme disease, which affected over 89,000 people in 2023 according to the CDC. Outdoor enthusiasts, particularly hikers and campers, are at higher risk of tick exposure during summer months. Effective repellents, such as those ranked by Consumer Reports, can reduce the likelihood of tick bites and associated illnesses. However, users should be cautious about potential material damage caused by DEET-based products, as noted in the report.
