Dangerous Pests

The sleek, black roof rat is one of the most common species of rats in the United States. These pests cause significant damage through their gnawing, nesting, and burrowing habits. However, roof rat diseases are the most serious concern for people and pets.

Types of Roof Rat Diseases

There are several diseases roof rats can transmit to humans. These include:

  • Leptospirosis - This illness causes a wide range of symptoms such as fever, aches, stomach distress, and chills. It may progress to meningitis or liver and kidney failure if left untreated.
  • Plague - Deadly if ignored, plague results in flu-like symptoms as well as swelling, tenderness, shock, and bleeding.
  • Salmonellosis - Brought on by Salmonella bacteria, this roof rat disease causes diarrhea, cramps, and fever.
  • Rat-Bite Fever - Symptoms of rat-bite fever include vomiting, aches, pains, and rash.
  • Typhus - This ailment inflicts headaches, rash, and fever.

How Do Roof Rat Diseases Spread?

Infections spread in several ways. Direct contact with a roof rat, dead or alive, puts people at risk for rat-bite fever. Bites and scratches are especially dangerous.

Some roof rat diseases can also infect people indirectly. Fleas from diseased rodents spread typhus and plague. Likewise, touching rat waste or consuming it through contaminated food or water can inflict salmonellosis and leptospirosis.


Homeowners must always be cautious when dealing with rodents. To stay safe and prevent the spread of roof rat diseases, contact the pest specialists at Critter Control. They have all the tools and know-how to remove and thwart infestations.

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!
