Ultrasonic pest repellers are often promoted as a means of protecting people and pets from the bites of hematophagous arthropods, such as ticks. However, to date, there has been no published research on the effectiveness of these devices against the Australian paralysis tick, Neumann. The purpose of this study was to test the effectiveness of nine ultrasonic devices against female . Two arenas were constructed, one for the test (with the ultrasonic device) and one for the control (no device). Each arena had a test and an escape chamber, connected by a corridor. Twenty ticks were placed in each test chamber. After the ultrasonic device was operated for 1 h, the number of ticks in both chambers was recorded. Ten replicates were conducted for each device. The average number of ticks that moved from the test to the escape chamber was greater in all the test arenas, with three devices being statistically different from the control. However, the highest percent of ticks that escaped was only 19.5%. This amount is insufficient to offer adequate protection against tick bites and this study adds further weight to previous investigations that ultrasonic devices should not be employed in pest management.
超声波驱虫器常被宣传为一种保护人和宠物免受吸血节肢动物（如蜱虫）叮咬的手段。然而，迄今为止，尚未有关于这些设备对澳大利亚麻痹蜱（Neumann）有效性的已发表研究。本研究的目的是测试九种超声波设备对雌性蜱的有效性。构建了两个场地，一个用于测试（配备超声波设备），一个用于对照（无设备）。每个场地都有一个测试室和一个逃生室，通过一条走廊相连。在每个测试室放入20只蜱。在超声波设备运行1小时后，记录两个室中的蜱的数量。对每个设备进行了十次重复试验。在所有测试场地中，从测试室移动到逃生室的蜱的平均数量都更多，其中有三种设备与对照在统计学上有差异。然而，逃脱的蜱的最高百分比仅为19.5%。这个数量不足以提供足够的保护以防止蜱虫叮咬，并且本研究进一步支持了先前的调查结果，即超声波设备不应应用于害虫管理。
