Rats are flexible omnivores, so what they eat depends on where they live and what food they can reach. In homes and cities, rats often eat grains, pet food, scraps, and stored pantry items. Outdoors, they forage for seeds, fruits, plants, insects, and small prey. Their diet changes easily with the season and setting. Rats…
Yersinia pestis causes plague. The familiar story says rats carried infected fleas into homes, where the disease jumped to people and spread as bubonic plague. That story is partly right, but it is not the whole picture. Rats likely mattered in some outbreaks, while human fleas, lice, and close-contact transmission may have played a much…
Rats have lived beside people for a long time. The path from wild brown rats to pet rats is much newer than most people think. If you are asking how rats were domesticated, the short answer is that humans gradually selected the calmest, most colorful, and most human-tolerant rats over many generations. Wild rats started…
Rats and mice are closely related rodents. They belong to the same broader mammal family tree. The short answer is that rats and mice are different animals in the same large family. They share many traits, but they are not the same species or even the same genus. You can spot many similarities in their…
You may picture rats scurrying up a gangway or slipping through a cargo hatch. That is one realistic way they can get aboard. On modern ships, rats usually board through a mix of port-side access, supply chains, and rare failures in pest barriers. Most cruise ships do not have a rat problem, but rodents can…
A healthy rat can often fall from several stories and still walk away, especially if it lands on a softer surface and manages to right itself in mid-air. That resilience comes from a low body mass, a relatively low terminal velocity, and a body built to absorb impact better than larger animals. Not every fall…
Rats use tiny, easy-to-miss openings to access food, water, and shelter inside houses. They usually exploit cracks, gaps, vents, pipes, and damaged exterior materials before you notice a problem. If you find and seal those access routes early, you can stop a rat infestation before it starts. Rats do not need a large opening. They…
Rats evolved through a long series of changes shaped by climate shifts, geographic spread, and close contact with changing ecosystems. They began as small early rodents, split into specialized lineages over millions of years, and developed traits that help them survive in many habitats. Their story forms part of the broader evolutionary history of rodents,…
Rats usually travel farther than you expect, but their daily range is still fairly limited. Many rats stay within about 300 feet of their nest while foraging, though they may push farther when food, water, or shelter is scarce. That range tells you where to look for activity around your home, yard, or business. It…
Rats in walls can turn a quiet home into a source of noise, odor, and damage. When you hear scratching at night or find other signs of rats, the problem often hides in wall voids where rodents nest, travel, and chew without being seen. If you want to stop a rat infestation, you need to…
