Vitamin K is a fat‑soluble micronutrient essential for blood clotting and bone metabolism in mammals. Green beans contain measurable amounts of vitamin K₁ (phylloquinone), typically 15–20 µg per 100 g of fresh tissue. When rats ingest green beans, they receive this nutrient alongside other vitamins, minerals, and fiber.. Date latest changes:
Effective Bait for Rats and Mice: How to Choose
Rodents consume a wide range of foods, but their intake concentrates on high‑energy, readily digestible items. Natural diets include grains, seeds, fruits, insects, and occasional animal protein. The preference for carbohydrate‑rich substances drives foraging behavior and influences bait attractiveness.. Date latest changes:
What sound repels rats and mice
Rats and mice detect sound through a cochlear system tuned to high‑frequency vibrations. Their auditory range extends from roughly 200 Hz up to 80 kHz, with peak sensitivity between 10 kHz and 30 kHz. Frequencies within this band provoke startle responses, disrupt navigation, and interfere with communication, making them effective for acoustic deterrence.. Date latest changes:

Why a Domestic Rat Bites: Aggression Causes
Territorial behavior is a primary driver of bite incidents in pet rats. When a rat perceives an area as its exclusive domain, any intrusion—whether from another rat, a human hand, or a foreign object—can provoke a defensive response. This response often manifests as a quick, forceful bite aimed at expelling the perceived intruder.. Date latest changes:
The domestic rat (Rattus norvegicus) descends from wild populations that inhabited Eurasian grain stores and river valleys thousands of years ago. These ancestors, commonly identified as the brown rat and the black rat (Rattus rattus), thrived in environments rich in human refuse, where natural selection favored opportunistic foraging, high reproductive rates, and adaptability to varied climates..
