Damage Caused by Norway Rats

Norway rat damage is easy to differentiate from that of similar species, as these robust rodents are uniquely capable of compromising the structure of a home with their burrowing. In fact, this behavior can also lead to the undermining of seawalls.

Additionally, all rodents have an excessive need to chew, as they must keep their incisors at the appropriate length. Finding gnawed household items, such as stored packages, wires, and even walls, is a typical indicator of Norway rat damage.

Norway Rat Problems

Known for their filth, these pests contaminate everything from pantries to attics with their urine and feces. Norway rats are also responsible for spreading diseases such as leptospirosis and rat bite fever.

Signs of Norway Rat Infestation

To reduce the amount of damage, residents must be aware of infestations. Some of the most common signs include:

  • The sight of droppings along runways and near shelter areas
  • Smudge marks on walls and beams, which are a result of the Norway rats' fur rubbing against surfaces
  • Burrows, usually found near the perimeter of homes or under bushes
  • Visible chew marks on walls, wires, or doors
  • The sound of scratching or climbing inside walls, especially during evening hours

Rat Control & Removal

When the signs of infestation and damage are clear, homeowners must take appropriate action. Removal is most effective when the professionals at Critter Control are contacted, as they have the expertise and experience to remove Norway rats and prevent future damage.

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!
