Rodent Clean-Up

When rodents such as; squirrel, mice or rats have gained entrance into your home or business, attic restoration (restoring your attic to it’s original clean, safe state) is an important part of your nuisance wildlife control solution. Here is a list of problems that rodents can cause while in your attic:

  1. Odor problems from urine and feces
  2. Growth of mold
  3. Rodents bring in parasites and other pathogens
  4. Rodents bring in nesting materials, food and other debris
  5. Rodents poop and urinate on insulation
  6. Rodents chew on everything, wiring, wood, sheet rock and more
  7. Their pheromone scent often attracts new wildlife to the home or business

“Restoring the attic to it’s original state by cleaning and decontaminating the space is very important”

How To Remove Contaminated Insulation DIY

Make sure before you begin this process that all wildlife has been removed and the home is animal proofed, meaning all holes have been properly sealed and caulked. You do not want to go through the expense and labor of removing insulation, cleanup and replacing insulation to have another animal move right in. This has happened to many homeowners.

Materials Needed:

  • plastic gloves
  • hazmat suit with hood
  • respirator
  • shoe covers
  • Hepa  vacuum
  • industrial vacuum if you have blown in insulation
  • plastic bags
  • plastic sheeting 3 ply or heavier
  • tape
  • dumpster
  • enzyme cleaner
  • insulation

Let’s Get Started

  1. Quarantine the contaminated area. This process will stop the spread of hazardous material into your home. For example if your attic is in your closet, close off the closet with heavy plastic.
  2. All insulation that has been contaminated with urine, feces and nesting or food should be bagged and removed. This should only be done by wearing the proper protective gear. Most rodent attic cleanups require you to remove all of the insulation, the reason is due to the amount of feces and urine, size of feces and most rodents burrow under the insulation, so to do a thorough cleanup all insulation has to be removed.
  3. When all of the insulation has been removed and all the feces has been removed, the attic should be sprayed with a antimicrobial enzyme. This will kill any diseases or parasites living in the space
  4. Replace insulation to at least building code requirements. (If we are doing the re-insulation we exceed the requirements) Be mindful of recessed lighting and any other areas of concern.


Reason’s To Wear Protective Gear

Bacteria which cause disease in humans and animals and is transmitted to humans by eating foods contaminated with animal feces. Salmonellosis can lead to severe cases of gastroenteritis, enteric fever septicemia (blood poisoning) and death.

Hantavirus Pulmonary Syndrome
Squirrels excrete the virus in their urine, saliva, and droppings. A person may be exposed to hantavirus by breathing in contaminated dust after disturbing or cleaning rodent droppings or nests, or by living or working in rodent-infested settings. Fever, muscle aches, shortness of breath and sever cough can develop, quickly progressing to the point of hospitalization.

Dead Animal Carcasses
When an animal dies inside your home, rat/mouse poison is often to blame. Dead animals cause terrible odors and their corpses become breeding grounds for flies and other disease vectors.

Humans are infected through contact with water, food, or soil containing urine from these infected animals (i.e. squirrels, rats, mice). The disease can also be transmitted through direct contact with urine, blood or tissue from an infected animal. The bacteria can enter through broken skin or through the soft tissues on the inside of the mouth, nose or eyes. Symptoms include fever, headaches, weakness and vomiting.
