Effectiveness of Ultrasonic Repellers Against Mice and Rats
Views: 834. 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: 617. 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.

Origin of Rats: Evolutionary History
Views: 39. Date latest changes: .
The earliest members of the murid lineage appear in the early Oligocene, roughly 34–30 million years ago, when diversifying rodent clades colonized Eurasia and North America. Fossil material from the Messel Pit (Germany) and the Rusinga Island deposits (Kenya) documents small, squirrel‑like forms that exhibit the dental pattern characteristic of murids:
Giant Rat Caught: Rare Observation
Views: 24. Date latest changes: .
The sighting occurred in the northern sector of the abandoned industrial complex known as Riverside Yard, a site characterized by dilapidated warehouses and overgrown loading docks. Observers recorded the event at approximately 02:17 a.m. local time, when ambient temperature dropped to 8 °C and humidity rose to 72 %.
How Mice Sleep: Rodent Sleep Patterns
Views: 21. Date latest changes: .
Light exposure profoundly shapes mouse activity cycles. During the dark phase, mice exhibit heightened locomotion, foraging, and grooming, reflecting their intrinsic nocturnal drive. In contrast, the light phase suppresses these behaviors, promoting periods of quiescence that align with the onset of sleep.
White Mouse: Photos and Description
Views: 41. Date latest changes: .
White mice appear repeatedly in mythic narratives, where their pale coloration associates them with purity, transition, and the supernatural. In ancient Greek lore, the white mouse serves as a herald of the goddess Hecate, delivering omens during nocturnal rites.

Identifying rat presence is the first step in selecting an appropriate, low‑risk control method. Accurate detection prevents unnecessary exposure to hazardous substances and ensures that targeted treatment is applied only where infestation is confirmed.
How to Repel Rats from the House?

Cracks in a building’s foundation provide direct pathways for rats to enter living spaces. These openings allow rodents to move from soil or crawl spaces into walls, floors, and rooms, where they can establish nests and cause damage. Sealing such gaps eliminates one of the most reliable access points, thereby reducing the likelihood of infestation.
