Effectiveness of Ultrasonic Repellers Against Mice and Rats
Views: 891. 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.
Ultrasound for Repelling Mice: Effectiveness
Views: 628. 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.
Bromadiolone Against Rats: Effectiveness
Views: 625. 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.

Why Do Rats Turn Gray? Causes of Fur Color Change in Aging Rats
Views: 31. Date latest changes: .
Eumelanin and pheomelanin are the two primary pigments determining the coloration of rodent fur. Eumelanin, a dark polymer, absorbs a broad spectrum of visible light, producing black or brown shades. Pheomelanin, a lighter polymer containing sulfur, reflects more light and yields red, yellow, or cream tones.
Pear for Fancy Rats: Safe Treat?
Views: 21. Date latest changes: .
Pears can be incorporated into a balanced rat diet, providing moisture, fiber, and a modest amount of natural sugars. Rats thrive on a base of high‑quality rodent pellets, supplemented with occasional fresh produce; fruit should remain a minor component to prevent nutritional imbalances.
Dreams About Many Mice: Interpretation and Meaning
Views: 13. Date latest changes: .
Dreams in which a multitude of mice appear often signal underlying psychological dynamics rather than literal concerns about rodents. The sheer number of small creatures amplifies the symbolic weight, prompting the mind to address clustered anxieties, feelings of vulnerability, or perceived loss of control.
