Common types of cockroaches in Idaho

Cockroaches have existed on this planet for millions of years and nearly every continent has them. The state of Idaho is no different. Idaho's climate varies from season to season and there are cockroaches that thrive in nearly all of them. So when winter comes to Idaho, you still need to worry about cockroaches.

Why do cockroaches exist?

Cockroaches are survivors. This is why they have managed to exist for millions of years, despite changes in climate and animal species dominance. They adapt well to different environments and food sources and thrive in damp places with easy access to organic matter, water sources, and shelter, which is why they often end up in basements, kitchens, or crawl spaces. Some species like German cockroaches (Blattella germanica) and American cockroaches (Periplaneta americana) prefer warm, humid areas and are quick to reproduce, making infestations hard to control without professional help.

These household pests can contaminate surfaces and food, posing potential health risks. While some may only crawl out at night, they can infest homes year-round. The presence of cockroaches in Idaho often surprises homeowners during the colder months, but their need for warmth and food can drive them indoors.

Common cockroaches in Idaho

There are three common cockroach species in Idaho, but it’s worth noting that other species, like the Oriental cockroach, can be found in the state. This can happen when these pests hitchhike on goods transported from other parts of the country. Let’s look at common cockroaches in Idaho.

German cockroach

German cockroaches are small, brownish-red in color, with wings folded over the back. These pests hate the cold, which is why they move indoors and can be seen more often in the winter. German cockroaches are among the most common cockroaches in Idaho, so if you’re dealing with an infestation, there’s a good chance it’s this species. German cockroaches can lay many eggs and reproduce quickly, meaning an infestation can quickly grow.

Brown-banded cockroach

The next common Idaho cockroach on our list is the brown-banded cockroach (Supella longipalpa). These pests look a lot like German cockroaches, but they are a bit darker in color. Their wings don’t entirely cover their abdomen, and they have the telltale light brown bands across the wings and abdomen.

American cockroach

This pest is also sometimes referred to as the ship cockroach, kakerlac, the Bombay canary, or palmetto bug. American cockroaches are reddish-brown in color and some of the largest cockroaches in North America, growing to just over 1 ½ inches in length. They have leathery forewings, chewing mouthparts, and antennae divided into segments.

How do Idaho cockroaches get into the house?

All cockroach species can fit through tiny cracks in the walls and foundations of homes and businesses. Cockroaches are generally looking for warmth, food, and a place to rest.

These pests can also get inside through openings when garbage cans or dumpsters are located right near windows and access points. Roaches can even hitch rides in products, boxes, produce, and other items brought inside from outdoors. Cockroaches can be an issue whether you’re in a city like Boise or a more rural part of Idaho.

How to prevent Idaho cockroaches from getting indoors

To help stop cockroach infestations, repair holes in siding, walls, brick, and screens. Installing door sweeps for garage and exterior access doors may also help. Additionally, make sure garbage cans, piles of garbage, and dumpsters are away from doors and windows.

Roaches can use piles of wood and vegetation near homes and walls to gain access indoors. Move any woodpiles away from the wall and trim vegetation away from the siding. Make sure grass is trimmed and bushes and shrubs are neat and not directly up against the wall.

Keeping your house and kitchen tidy is also important. Just like ants, cockroaches can use food they find on the floor or under cabinets and kitchen counters as nutrients. They can then begin to reproduce quickly. Investing in a dehumidifier may help deter cockroaches, as they prefer damp places, but this may not work with all species.
