Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Scientific studies evaluating ultrasonic pest repellers have consistently found that these devices lack sufficient efficacy to control household pests or other animals.

The analysis

The claim is specific and empirical, passing Step 0. Among the retrieved papers, paper [1] directly tests ultrasonic pest repellents against ticks and finds them ineffective for pest management, while paper [3] shows similar lack of efficacy for sonic-ultrasonic repellers on birds. Papers [0], [2], and [4] are tangential (discussing fly genetics, baculoviruses, and water heaters respectively). The available evidence clearly contradicts the claim.
