Cockroaches prefer to stay hidden during the day and can sense our vibrations at night. So they quickly dash away before they are even discovered.

One tip to know, if you see a cockroach during the day, there may be more that you don’t see and you may have an infestation. So please call an exterminator for help.

3 COMMON cockroaches in Alaska:

  • The abdomen is slender and tapers down, with a yellowish underside.
  • Females are darker brown, and their abdomens are broader.

The German Cockroach comes out at night to search for food and water and will quickly dash away if you turn on a light or disturb them. They are plant and meat scavengers. This cockroach is attracted to meats, starches, sugars, and fatty foods. Unfortunately, if they can’t find food, they may eat household items such as soap, glue, and toothpaste.

They will invade houses, apartments, restaurants, hotels, hospitals, and other institutions. During the day, this cockroach hides out and occupies tight spaces around refrigerators, stoves, sinks, and in the walls. So it is difficult to know if you have a cockroach problem. 

If you EVER see a German Cockroach during the day, this may indicate that you have a severe infestation.

Unfortunately, they don’t stop there. These cockroaches are frequently found in homes and apartments because they come up through the sewage and plumbing systems or air ducts. You can find them in basements, crawl spaces, and cracks in foundations.

These cockroaches are not picky eaters. This species will eat beer, leather, hair, flakes of dry skin, fermenting foods, starch from book bindings, and dead animals, including other cockroaches. They eat almost anything they walk on!

The American Cockroach has odorous secretions that can alter the flavor of food, and if there is a high population of them, you will be able to smell it.

This cockroach can also pick up disease-causing bacteria like Salmonella on their legs and deposit it on other food that they walk on. This can cause food poisoning or infections. In addition, house dust that contains cockroach parts or feces can trigger an allergic reaction and asthma in certain people.
