Effectiveness of Ultrasonic Repellers Against Mice and Rats
Views: 809. 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: 613. 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: 611. 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 Rats Lose Hair in Patches: Causes and Treatment
Views: 24. Date latest changes: .
Patchy hair loss in rats refers to the development of distinct, non‑contiguous areas where fur is absent or markedly thinned, while surrounding coat remains intact. The condition manifests as smooth skin patches that may vary in size from a few millimeters to several centimeters and can appear on any body region, most commonly on the back, flanks, and tail base.
What Rats Transmit to Humans? Infections and Risks
Views: 33. Date latest changes: .
Direct contact with rats creates a pathway for pathogens to move from the animal to a person. Transmission occurs when skin or mucous membranes encounter contaminated fur, saliva, urine, or blood. Common agents transferred through this route include:
Rat Control: What It Is and How It Is Performed

Recognizing stress and fear in rats is essential for establishing a trusting relationship with a pair of rodents. Observable indicators fall into three categories: behavioral, vocal, and physiological. Rapid grooming or excessive licking of fur, especially when directed toward a specific body part.

Domestic mice typically reach adulthood within eight weeks and may live between two and three years under optimal conditions. Several variables determine the observed average longevity. Genetic background exerts a primary influence. Inbred strains often display shorter lifespans than outbred populations because of reduced heterozygosity and the presence of deleterious alleles.
Pet Rat Breathing Difficulty: Possible Causes
Views: 40. Date latest changes: .
Rats experiencing respiratory distress display several observable signs that indicate compromised breathing. Recognizing these manifestations allows timely intervention and reduces the risk of severe complications. Open‑mouth breathing, especially when the rat holds its mouth ajar while at rest.
