Are There Rats in Idaho?

Yes, there are rats in Idaho, and the two most common species found are the Norway rat (Rattus norvegicus) and the roof rat (Rattus rattus). These rodents, while not native to Idaho, and quite rare, have established populations in urban areas, farms, and even rural locations. The presence of rats in the state has increased with urbanization and the expansion of human habitation.

Norway Rats in Idaho

The Norway rat is the more prevalent of the two species in Idaho. These rats are larger and are commonly found in urban environments where they can thrive in sewer systems, basements, and other structures that provide shelter. Norway rats are known to be excellent burrowers, making them a common pest around homes, farms, and food storage areas. They are also notorious for their destructive chewing behavior, which can cause significant damage to property and electrical systems.


Roof Rats

Roof rats, although less common than Norway rats, are also found in Idaho. Unlike the burrowing Norway rat, roof rats prefer higher ground and are more likely to be found in attics, roofs, and trees. These rats are excellent climbers and often enter homes through roofs or other high points.


Impact on the Environment

Rats are known for their ability to adapt to various environments, and Idaho’s climate, particularly in cities like Boise, offers conditions conducive to their survival. They tend to seek shelter in buildings during the colder months and can be a year-round nuisance. In addition to property damage, rats pose significant health risks, as they can carry pathogens that spread diseases to humans, such as hantavirus, leptospirosis, and salmonella.


Prevention and Control

Preventing rats from invading homes and properties in Idaho involves sealing entry points, maintaining cleanliness, and eliminating food sources that might attract them. In urban areas, proper waste management is essential to reducing rat populations. For more severe infestations, professional pest control services are often recommended to effectively manage and eliminate rat populations in both homes and businesses (Harmston & Wright, 1960).


Conclusion

Rats are indeed present in Idaho, particularly in urban areas where they find food and shelter. While they pose various risks, from property damage to health concerns, proper prevention methods and professional pest control can help manage and mitigate these pests.

Is it worth hiring a pest control company?

December 4, 2025
Homeowners ask us this all the time, and it usually comes right after they’ve already tried battling ants, spiders, wasps, or roaches on their own. We’re upfront about this. Hiring a pest control company isn’t always necessary. Sometimes a simple fix solves the issue. But in many cases, professional service is worth every penny because it prevents problems from getting bigger, more expensive, and far more stressful. Here’s a breakdown based on what we’ve seen firsthand in thousands of homes across Boise, Meridian, Eagle, Nampa, Kuna, Caldwell, and Star.

Why You Should NEVER Squish a Roach

December 4, 2025
Roaches are one of the most hated pests on earth. When one darts across the kitchen floor, the first instinct is usually to grab a shoe and end it right there. We get it. We’ve walked into homes across Boise, Meridian, Eagle, Nampa, Kuna, and Caldwell where people proudly tell us, “Don’t worry, we killed a bunch of them already.” But here’s the truth: squishing cockroaches is one of the worst things you can do during an infestation.  We’ve spent years battling German roaches in Treasure Valley kitchens, bathrooms, restaurants, and apartment-style setups, and we’ve seen firsthand how crushing them can make the problem worse. Below is the breakdown of why.

What is the hardest pest to get rid of?

December 4, 2025
When homeowners ask us which pest is the hardest to eliminate, they’re usually expecting one of two answers: cockroaches or bed bugs. And for good reason. Both are notorious, both are stubborn, and both can make even the cleanest home feel like a battleground. But after years servicing thousands of homes across Boise, Meridian, Eagle, Nampa, Kuna, Caldwell, Star, and even down to Mountain Home and up through Weiser, we’ve learned that the question isn’t quite that simple. The hardest pest to eliminate isn’t just about biology. It’s about behavior, environment, customer expectations, and the realities of what a pest control technician faces inside a home.

Surprise- The Deadliest Animal In The US Isn't The One You'd Think

By Dan Christensen • August 28, 2025
When most people in Idaho hear the phrase “deadly animal,” they think of rattlesnakes on a hot trail, a mountain lion lurking in the foothills, or even a bear deep in the woods. But the numbers tell a different story—and it’s far closer to home than you might imagine. According to CDC data, between 2018 and 2023 there were 1,604 animal-related deaths nationwide, an average of 267 per year. What’s alarming is that this number is steadily climbing—up 38% in just five years. And the top culprit? Not snakes. Not cougars. Not even bears. It’s the buzzing stingers in your own backyard: hornets, wasps, and bees. Stinging Insects: America’s #1 Killer
