How Do Rats Affect the Environment?
WouterRats are common on tropical islands and can have high population densities. This is likely due to the high recruitment of young and the year-round warm climate, which facilitates breeding. However, rats are also a serious threat to birds. Almost all types of tropical land and seabirds are affected by rats. While the Pacific rat is the leading cause of declining land bird populations, black rats have also contributed to the problem.
Rats are omnivorous and can live in many environments, including buildings, walls, and attics. They will dig burrows where they can find food and warmth. They will also chew through the gap between an interior and exterior wall to get to a food source. These rodents leave trails of mud and grass as well as grease marks, which are easy to detect under a black light.
Rats and mice are often nocturnal, but they can be active during the day, especially if they are in large numbers. This is a sign of a substantial infestation. Rats may try to enter your home and may even be attracted to your pets, including cats and dogs. The smell of urine and musky odors is also a good sign of a rodent infestation.
Rats can negatively affect the environment, but they also serve a valuable purpose in the ecosystem. They feed on a variety of plants and fruits, and contribute to the depletion of native species. They also cause significant damage to structures, including books, furniture, and appliances.
