Ultrasonic Pest Tester Showdown: Home vs Pets Safe… Coverage Insight We recently tested the 6 Packs Ultrasonic Pest Repeller for its effectiveness and safety around pets, and were intrigued by its claims of 1200 sqft coverage. Plugging our units into key areas of our home, we observed a noticeable reduction in mouse and spider activity over a few weeks. The 360° design ensured consistent coverage, eliminating blind spots we feared might attract pests. While we appreciated the pet-safe frequency, our furry companions showed no signs of distress. The plug-and-play simplicity was a plus, though we noted our roach population took slightly longer to dwindle. Overall, we consider this an affordable, low-maintenance solution for controlling common pests without harsh chemicals, making it a worthy contender for our homes.
