Effectiveness of Ultrasonic Repellers Against Mice and Rats
Views: 742. Date latest changes: .
Ultrasonic devices emit sound waves above 20 kHz, a range beyond human auditory perception but within the hearing capabilities of most rodent species. Laboratory measurements show that common laboratory mice detect frequencies up to 100 kHz, while rats respond to sounds up to 80 kHz.
Bromadiolone Against Rats: Effectiveness
Views: 605. Date latest changes: .
Bromadiolone is a second‑generation anticoagulant rodenticide belonging to the 4‑hydroxycoumarin family. It interferes with vitamin K recycling, preventing the synthesis of clotting factors II, VII, IX, and X, which leads to fatal internal hemorrhage in rodents after a single lethal dose.
Ultrasound for Repelling Mice: Effectiveness
Views: 596. Date latest changes: .
Ultrasonic deterrent devices operate by emitting sound waves at frequencies above the human audible range, typically between 20 kHz and 100 kHz. Mice possess auditory receptors tuned to this spectrum, allowing the waves to be detected and processed by their cochlear hair cells.

Hairless rats are commonly referred to as “nude” or “hairless” strains, a designation that reflects the absence of a normal pelage. The phenotype results from mutations that disrupt the development of hair follicles during embryogenesis. The primary genetic alteration underlying this condition is a loss‑of‑function mutation in the Foxn1 gene.

Anticoagulant rodenticides are chemical agents that interfere with the blood‑clotting cascade of rodents, leading to fatal internal hemorrhage. They are divided into first‑generation compounds (warfarin, chlorophacinone, diphacinone) and second‑generation compounds (bromadiolone, difenacoum, brodifacoum) based on potency and persistence.
