Norway Rats in the U.S.

Despite their international-sounding name, Norway rats are extremely common throughout the United States. They are what most people think of when visualizing a rat: sto cky rodents 12 to 18 inches long that weigh one pound and are brown to gray in color. The pests are found in every state.

How Norway Rats Get in the House

It is not unusual to find Norway rats in houses, as they have many skills at their disposal that make it easy to access a residence. These pests can gain entry by:

  • Climbing exterior walls
  • Jumping from trees
  • Chewing their way through with their sharp teeth


Having a Norway rat in the house can cause problems in multiple ways. It will contaminate groceries and pet food, which is a health hazard. Urine and droppings accumulate behind walls and in attics, fouling air quality and damaging wood.


Additionally, the pests have destructive habits that can cause structural damage, including gnawing on wiring and plumbing. Their chewing also damages wood, insulation, and siding. Norway rats gather in yards and can weaken foundations with their digging before they move into the house.


For all these reasons and more, it is important to assert early control over infestations. When allowed to persist, rapid breeding can cause populations to swell. The professionals at Critter Control can remove Norway rats in the house and keep them from coming back.

BAT POOP CLEAN-UP AND PREVENTION! Bat guano removed from gables. No bats found in attic, so put new screens on all gable vents, as one screen was close to breaking and then bats may have gotten in! Great work in Tulsa!

Squirrels and chipmunks were in our attic. So we called Critter Control to do an inspection. Their representative climbed all over our very steep roof and found several places where squirrels had entered our attic.

Upon inspection of the attic, evidence of bats was also found. The Critter Control team came on time to completely caulk the entire perimeter of the house and create an exit strategy for the squirrels and bats.

Because bat droppings can cause histoplasmosis, this also required total removal and replacement of our attic insulation and sanitizing the space. Not a small job in a 1,300 sq. ft. attic! While Critter Control’s cost was high, our homeowners insurance covered most of it. Everyone representing Critter Control was professional, courteous and timely. I would highly recommend them to anyone who thinks they might have unwelcome guests living in their attic

On recommendations from a nearby pest control company, I called Critter Control for suspicious bat droppings.

Madison came out the same day to do an inspection. She was knowledgeable, thorough, and highly professional. She examined the ‘matter’ that had been scattered on my threshold and thought it was foliage. But she then asked to go up to my attic space where the bats could be roosting. She had to walk up 3 flights of stairs with a heavy ladder. She again spent some time searching all the nooks and crannies and found nothing.

She seemed so interested in her craft, it was truly inspiring to see! She reassured me and is writing up a prevention strategy for my appraisal. She charged me NOTHING!! I am so impressed. We need more Madisons in this world!

We noticed droppings on our brand new deck - we were given their number from our contractor. They came the next day. Brian looked at it and said - yeah, bats!! He then checked every area in our attic and he explained exactly what needed to be done.

He found evidence of a mice infestation, provided a referral and they are helping us as well. Great service, very informative, very professional! We are very satisfied and would recommend them to anyone who has any issues with any critters!
