Effectiveness of Ultrasonic Repellers Against Mice and Rats
Views: 829. 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: 616. 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: 615. 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.

Rats maintain low temperature in their paws through a specialized vascular network that limits heat transfer to the environment. The digital region receives blood via a branching arterial tree that terminates in a dense capillary plexus. Arterioles at the periphery are highly innervated by sympathetic fibers, allowing rapid adjustment of vessel diameter in response to ambient temperature.

Droppings and urine odors indicate active rodent activity and pose health hazards that require prompt professional intervention. Mouse feces are small, dark, and often found near food sources, while urine leaves a lingering ammonia scent that can permeate walls, insulation, and upholstery.
Why Do Rats Coos? Causes of Their Characteristic Sounds
Views: 18. Date latest changes: .
Rats produce a range of vocalizations, each serving specific communicative functions. Cooing, a low‑frequency, soft, continuous sound, differs markedly from other calls such as squeaks, chirps, and ultrasonic whistles. Key acoustic and behavioral markers separate cooing from alternative rat noises:
