Effectiveness of Ultrasonic Repellers Against Mice and Rats
Views: 757. 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: 601. 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.

How to Stop a Rat from Soiling Inappropriate Areas
Views: 20. Date latest changes: .
Rats use scent marking to claim territory, signal reproductive status, and communicate stress. When a rat deposits urine or feces in a specific spot, the odor signals ownership and deters other rodents from entering. This behavior often leads to repeated soiling in the same area, especially if the space is perceived as safe or attractive.
What to Do If a Rat Appears in the House?
Views: 18. Date latest changes: .
When a rodent is suspected indoors, the first decisive action is to obtain clear visual evidence. Direct observation eliminates uncertainty, guides the choice of control measures, and prevents unnecessary escalation. Begin by inspecting areas where rats commonly travel.
Safe Mouse Control Methods in the Home

The recent investigation into rodent submersion yielded quantitative data on physiological responses, mortality rates, and recovery potential under controlled conditions. Measurements included heart rate variability, blood gas levels, and neural activity during immersion and after rescue.
What to Do If a Rat Has a Cold
Views: 15. Date latest changes: .
Rats suffering from a cold may exhibit signs that indicate compromised breathing. Recognizing these signs promptly allows for timely intervention and reduces the risk of progression to pneumonia or other serious conditions. Key indicators of respiratory distress include:
