Identifying Roof Rat Droppings
The two species of rat that most frequently nest in human residences are Norway and roof rats. Differentiating between them by sight is easy, as one is much larger than the other. They are also recognizable by their feces. Roof rat droppings are smaller than those of Norway rats, measuring an average of one half of an inch in length. They are black and curved with tapered ends, while Norway rats produce brown feces with blunt ends. Roof rat droppings are rarely found in clusters because the pests defecate while walking, whereas Norway rats leave their pellets in groups.
Dangers of Rat Poop
Roof rat droppings are known to carry disease-causing pathogens. Among these are Leptospira and Salmonella bacteria, Histoplasma mold, and Hantavirus. The most common method of transmission is inhalation. When rat droppings are disturbed, pathogens become airborne. Some of these, including Hantavirus, can remain in the air for several days. Additionally, flies and other larvae are attracted to roof rat droppings. These pests bring with them a host of other diseases dangerous to humans.
Since roof rats are agile climbers, they tend to live in attics and rafters. Place rat traps up high, rather than along baseboards, to catch these pests. To remove their means of entry, vines, ivy, and overhanging branches should be cut back from walls. Additionally keep kitchens and pantries clean and trash can lids closed tightly to limit the rats’ food sources.
