Effectiveness of Ultrasonic Repellers Against Mice and Rats
Views: 818. 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: 614. 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.

Rabies is a neurotropic virus transmitted primarily through saliva of infected animals. The virus enters a new host when saliva contacts an open wound, mucous membrane, or damaged skin. Bats, raccoons, foxes, and feral dogs are the most common reservoirs;
Mouse and Rat Repellent: Review of Effective Products
Views: 560. Date latest changes: .
Ultrasonic devices emit high‑frequency sound waves that rodents cannot hear but find uncomfortable. Frequencies typically range from 20 kHz to 65 kHz, producing a pulsating signal designed to deter mice and rats from entering or remaining in a treated area.

Brown mouse: distinguishing features
Views: 27. Date latest changes: .
The brown mouse exhibits a compact body plan that facilitates agile movement through dense vegetation and indoor structures. Adult individuals commonly attain a total length of 7 – 10 cm, excluding the tail, which adds an additional 6 – 9 cm.
How Long Does a Rat Need to Recover After Anesthesia?
Views: 47. Date latest changes: .
Inhalant anesthetics dominate rodent surgical protocols because they allow rapid adjustment of depth and swift emergence. Isoflurane, sevoflurane and halothane are the most frequently employed agents for rats. Their low blood‑gas partition coefficients enable quick clearance from the bloodstream once delivery stops, which directly determines the post‑procedure recovery interval.
Do Mice Chew Plywood? Potential Home Damage
Views: 18. Date latest changes: .
Mice possess a strong gnawing reflex that activates whenever their incisors encounter resistance. The reflex prevents over‑growth of teeth and is triggered by the hardness of the material, not by nutritional need. Consequently, even dense engineered wood such as plywood becomes a target when mice explore a building’s interior.
How the field mouse differs from the house mouse
Views: 22. Date latest changes: .
Rodents constitute the largest mammalian order, encompassing over 2,400 species that occupy ecosystems from arctic tundra to tropical rainforests. Their evolutionary success stems from adaptable dentition, rapid reproductive cycles, and versatile foraging strategies.
How Long a Dead Mouse Odor Persists and How to Remove It
Views: 18. Date latest changes: .
A dead mouse begins to break down immediately after death, releasing volatile compounds that generate the characteristic odor. The breakdown follows a predictable sequence: Fresh stage (0‑12 h): tissues soften, initial bacterial activity starts.
Mouse Experiment: New Discoveries in Neurobiology
Views: 35. Date latest changes: .
Early mouse research laid the foundation for modern neurobiology by providing a tractable organism for genetic manipulation, electrophysiological recording, and behavioral assessment. Researchers introduced targeted mutations to explore the role of specific proteins in synaptic transmission, establishing causal links between gene function and neuronal activity.
