5 Reasons Why Rodents In The Attic Are Bad and How to Remove Them

Months can go by before anyone enters the attic, which explains why it often becomes a nesting ground for rodents.

Below, we’ll discuss five reasons why rodents in the attic are harmful and how homeowners can hire a professional to remove them.

Why Rodents in the Attic are Bad

While these pests may be tiny, they have sharp teeth strong enough to chew through almost anything they encounter, except for metals and glass. Rodents are known for chewing:

  • Wires
  • Insulation
  • Wood
  • Plaster
  • Soil


While homeowners can find many of these materials, no home is entirely rodent-proof. These
annoying pests can create structural damage, but let’s dive into what they can do to attics.

  1. Leave filthy stains – Many rats and mice have furry bellies that, while traveling, track along grease, feces, and other unwanted filth. These stains and dirt can pose serious health risks if not addressed and properly cleaned. These stains are a dead giveaway that you have a rodent infestation in your attic, and you should contact a professional for an attic cleanup.

     

  2. Damaged electrical wiring – Rodents are known for chewing electrical wiring; while the damage isn’t structural, it can be dangerous. Damaged electrical wiring can cause appliances to malfunction and short-circuit, which may cause unwanted fires. Once a rodent begins chewing electrical wiring, the risk of a house fire increases dramatically.

     

  3. Create holes in rafters – Structural damage in attics often comes from rodent infestations and their determination to enter your home through the tiniest holes. No entrance is too tiny, as these creatures will keep chewing until they’ve made their way through. Rodents will continue to chew through attic rafters to enter other areas of your home.

     

  4. Destroy insulation – Rodents are known for making nests, in insulation and Attics are prime targets for rodents seeking shelter for nesting. Rats tear apart insulation to make space for their pups, while mice will burrow and form tunnels in your insulation.

     

  5. Damaged soffits – Aside from insulation, the comfortable space created by soffits is a rodent’s favorite. Soffits made of wood can deteriorate when exposed to rodent feces and rodent infestations.

5 Steps To Remove Rodents From Your Attic

A professional must remove your attic insulation to get rid of rodents and waste. Most importantly, removing your insulation will help reveal hidden entry points that these sneaky pests use to enter your home.

2. Disinfect & Sanitize

Disinfecting and sanitizing after removing rodent waste is required because it’s toxic to humans and can affect your home’s indoor air quality. Sanitizing and disinfecting the scent of rodents will ensure rodents don’t return and cause additional damage to your attic. Controlling rodents is virtually impossible if they’re not removed and disinfected correctly for several reasons.

  • Rodents are territorial – Like pets, rodents mark their territory with their urine and feces, so if you’re a pet owner, you know how it works. Once rodents smell the odor, they will continue to find ways to enter your attic; even if you attempt to seal up entry points, they’ll still gnaw their way through.
  • Waste is toxic to inhale – Many homeowners are unaware that rodent waste is toxic to inhale and can affect your respiratory system. According to the CDC, you should thoroughly clean and disinfect your attic after a rodent infestation to control the indoor air quality of your home and prevent your loved ones from becoming ill. 

3. Rodent-Proof Your Attic

Professionals can identify and seal all entry points so rodents cannot access your attic and find another hiding area. Rodents can access your attic through imperfections like pipes, gutters, and roofs. Rodent-proofing is an effective solution to create a barrier between the inside of your home and rodents outdoors.

To rodent-proof your attic, professionals will search for holes and gaps around chimneys, wires, vents, or anything that can lead rodents indoors. 

4. Air Seal Your Attic
