- Behavioral Patterns: A starting behavior that could need to be changed is that given enough time, groundhogs can get used to certain sounds which means that the long-term effectiveness is diminished.
- Obstructions: Barriers like walls, vegetation, and fences can make it harder for ultrasonic waves to move freely which greatly limits the effectiveness of the device
- Coverage Area: The range of each device is predetermined, and to fully cover larger areas, multiple units may be required.
Some report success, but as with all things, results may vary. Blending ultrasonic techniques with other repellents may improve overall success.
