Rats and mice breed year-round in Hawai’i. The most common rat species associated with complaints in Hawaii are the roof rat (Rattus rattus) and the Norway Rat (Rattus norvegicus). The roof rat is an excellent climber and is found inhabiting trees, roof spaces, and attics.
Hawaii is an island state in the Pacific Ocean. It’s one of the 50 states of the United States, and it’s located about 2,500 miles from the mainland U.S., making it the most isolated state in the country. Most people know Hawaii for its beautiful beaches, especially since Honolulu has hosted multiple Olympic Games events. The islands are also known for their volcanoes, including Kilauea on Hawai’i Island, the largest active volcano in a chain that includes Mauna Loa on Maui and Mauna Kea on Oahu (and two other volcanoes).
Rats are incredibly difficult to get rid of, and the longer you leave them alone, the worse the problem will become. They’re smart, they breed quickly, and there are few things that can kill them. If you have rats in your home and don’t take action immediately, they’ll spread into every corner of your life, into your food storage areas, into your attic or basement (where they’ll build nests), and even into your walls. It’s not just a matter of having a few rats running around: it’s a full-blown infestation that requires immediate attention.
Are rats common in Hawaii?
The most common rat species associated with complaints in Hawaii are the roof rat (Rattus rattus) and the Norway Rat (Rattus norvegicus). The roof rat is an excellent climber and is found inhabiting trees, roof spaces, and attics. It can be distinguished from a Norway rat by its smaller size, and lighter coloration on its toes, ears, and underbelly.
The Norwegian or brown rat is larger than its cousin, weighing about six ounces when fully grown compared to only three ounces for a roof rat. In addition to being larger than its cousin they also have longer tails that are hairless with blunt ends that are shorter than their bodies. They also differ in color with browns having grayish fur on their back while roof rats have more reddish-brown fur over their entire bodies including their tails which do not turn white like those of other rats when scared or excited.
Rats are not native to Hawaii. Westerners brought species like the roof rat and the Norway rat to the island, while the Polynesian rat appeared on the island about 900 years ago. The lack of natural predators on an otherwise predator-poor island has allowed these rodents to thrive.
How did Hawaii get rid of rats?
Losing a few rats may not seem like a big deal, but the arrival of non-native species can be devastating to local ecosystems. Native Hawaiian birds and insects have evolved over millions of years with no competition from these invasive mammals, which also carry diseases unfamiliar to Hawaiians. In fact, an estimated 13 million birds are killed by rats every year on Oahu alone.
To understand how Hawai’i got rid of its rats, you have to go back many centuries, and thousands of miles away from its shores. The mongooses found in Hawai’i are native to India and were originally introduced to Hawai’i Island in 1883 by the sugar industry to control rats in sugarcane fields on Maui, Moloka’i, and O’ahu.
How big do rats get in Hawaii?
Rats in Hawaii are not as small as you might think. The Norway rat is the largest of all rats in Hawaii, weighing 10-18 ounces and measuring 8-10 inches long. It has a shorter tail than other rats, which makes it look like a large mouse rather than a rat.
The Norway rat also has thick fur that varies from brown to black, depending on where they live. They can be identified by their pointed snout and ears that stick straight up on top of their head (as opposed to tucking them under). They have lighter colored fur around their face and belly area with dark feet and tail end – but they do not have stripes as Roof Rats do. This species also has large incisors compared to other rodents so make sure you keep an eye out for those when identifying one yourself.
What animal was brought to Hawaii to get rid of rats?
Mongoose is a type of weasel, originally from India. They were brought to Hawaii in the 19th century by the sugar industry to control rats in sugarcane fields on Maui, Moloka’i, and O’ahu. Mongooses are similar to skunks and ferrets, but they do not have a bad odor like skunks do.
The mongoose did not survive well in its new environment because it was used to living in grasslands or forests near water sources where it could catch fish for food; however, Hawai’i is primarily an island chain with no oceans nearby to provide food for these animals.

Additional Info :
Rodents are a big problem in many homes, and you don’t want them to be in yours. They can cause damage and spread disease, but they can also be difficult to get rid of. Luckily, there are some great ways to keep them out of your home and keep them from coming back.
The first thing you’ll need is a good rodent repellent. It’s made with natural ingredients that will keep rodents away without harming them or your family. It keeps working for up to 30 days after application and can be used in any area of your home where rodents might try to enter.
You should also consider making some simple changes to your yard or garden if you have one near the house. Rats love digging holes and searching for food, so if you can eliminate those things from their environment, they’ll have no reason to come close enough for their scent receptors to pick up any signals from inside your house.
