Human-biting ticks threaten public health in the United States. Registration by the Environmental Protection Agency of products to kill host-seeking ticks or repel ticks contacting humans is indicative of their safety and effectiveness. Unregulated minimum risk products, exempt from Environmental Protection Agency registration and often based on botanical oils, are proliferating in the marketplace, but there is concern about their effectiveness to kill and repel ticks. Evaluations of such products are limited in the published literature. A review showed considerable variability among minimum risk products to kill host-seeking blacklegged ticks, with effectiveness similar to chemical pesticide products for some minimum risk products but minimal impact on the ticks for other products. Evaluations of minimum risk tick repellents have typically focused on individual active ingredients rather than formulated products, which often combine multiple active ingredients. Consumers should be aware that effectiveness to kill and repel ticks can differ among unregulated minimum risk products.
人咬蜱威胁美国公众健康。美国环保署对杀灭吸血蜱或驱避接触人体的蜱的产品进行登记，表明其具有安全性和有效性。不受监管的低风险产品，免于美国环保署登记，且通常基于植物精油，在市场上大量涌现，但人们对其杀灭和驱避蜱的效果存在担忧。此类产品的评估在已发表的文献中有限。一项综述显示，杀灭吸血黑腿蜱的低风险产品之间存在相当大的差异，一些低风险产品的有效性与化学农药产品相似，但对其他产品的蜱几乎没有影响。对低风险蜱驱避剂的评估通常侧重于单一活性成分，而不是通常结合多种活性成分的配方产品。消费者应该意识到，杀灭和驱避蜱的效果可能因不受监管的低风险产品而异。
