Rat Species in Hawaii
Most commonly found in urban areas, the Norway rat is known by many names, including the brown rat, street rat, and sewer rat. This species is the largest in Hawaii, measuring up to 10 inches in body length, with a tail of about the same length. Norway rats can often be found burrowing in the ground, sewers, trash piles, and garbage dumps.
Roof rats, or black rats, are considered the biggest threat to Hawaii homes and businesses due to their behavior and climbing abilities. This critter has a body roughly seven inches long, with a tail slightly longer than its body. Eating primarily fruits, the roof rat can be found everywhere from homes to areas of dense vegetation.
The smallest of all rat species in Hawaii, the Polynesian rat measures roughly five inches long and weighs only 2-3 ounces. Known as a field rat, this species will rarely be found close to Hawaiian homes and offices. Instead, the Polynesian rat would rather make its nest in rock piles, gulches, wastelands, and embankments.
