This guide will provide you with 10 strong reasons to keep rodents out of your attic, along with some expert tips to help you achieve this goal. So, read to the end!
Top Benefits of Attic Rodent-Proofing
1. Protect Your Insulation from Destruction
Rodent-proofing the attic prevents mice and rats from nesting in the insulation. Damaged insulation doesn’t work as well, which makes energy bills go up.
- Rodents eat fiberglass..
- Nesting materials block airflow
- Fixing insulation can be expensive.
Tip: Use steel mesh and expanding foam to fill in the gaps and keep them out.
2. Prevent Fire Hazards from Chewed Wires
Rodents chew electrical wires to stop their teeth from growing too long. This leads to fires and shorts.
- Attics are where 25% of unknown house fires start.
- Broken wires can cause fires and electrical problems.
- After you notice any signs of rodents, schedule regular inspections.
3. Stop Diseases from Entering Your Home
Hantavirus, leptospirosis, salmonella, and other diseases can be spread by rodents.
- Droppings make the air and surfaces dirty.
- HVAC systems spread disease.
- Kids and pets are especially at risk.
Put on a mask and gloves before going into your attic.
4. Avoid Expensive Structural Repairs
Wood, pipes, and ductwork that get chewed up require extensive repairs.
- Damage to the structure makes the roof less stable.
- Chewed pipes lead to water leaks.
- HVAC ducts are clogged with debris.
Look for droppings and gnaw marks on beams and corners.
5. Eliminate Foul Odors
Nests and droppings from rodents have a horrible smell. The smell of dead rodents is even worse.
- The smell from the attic gets into the bedrooms and vents.
- Without thorough cleaning, it can take weeks to eliminate odors.
Place one-way exclusion traps so that rodents can exit but not re-enter.
6. Prevent Nesting and Breeding
Mice and rats breed all year long, but they like to do it in warm, dark places like attics.
- One pair can have more than 200 babies in a few months.
- Infestations happen without a sound.
Rodent proofing in the attic can prevent nesting and breeding. Act now. One rodent today means dozens soon.
7. Maintain Your Property Value
Buyers don’t want to buy a house with an attic full of droppings, wires, and broken insulation.
- Home inspectors look for signs of rodents
- It costs more to fix things than to stop them from breaking.
A clean and safe attic can increase the value of a house when it’s sold.
8. Improve Indoor Air Quality
The air that enters your home from the attic is contaminated due to rodent droppings and dander.
- Allergies and asthma get worse.
- Air that is bad for the attic spreads through ducts.
After sealing your attic, using a HEPA vacuum is a great idea.
9. Lower Energy Bills
Rodent control in the attic helps the insulation work more effectively.
- Sealed attics keep cool and warm air inside.
- Less energy loss means lower bills.
Ensure that all soffits, vents, and gaps in the walls are completely sealed.
10. Peace of Mind
It feels good to know that there are no rodents in your attic.
- No sounds of scratching
- No worries about getting sick
- No extra costs
Rodent-proofing makes your home safe and comfortable for a long time.
Rodent-Proofing Tips from the Pros
Attic rodent proofing doesn’t have to be hard to keep rodents out of your attic. This is how professionals do it:
Look for Ways to Get In
Check vents, pipes, and cracks with a flashlight. A hole only ¼ inch wide is enough for mice.
Use metal flashing and steel wool
Rodents can’t eat through metal. Put it in holes and corners.
Put in door sweeps and screen vents.
Ensure the roof vents and attic hatches are securely closed. Don’t leave them open or broken.
Trim Tree Branches
Rodents use trees to jump into attics. Make sure branches are at least 6 feet away from the roof.
Don’t put food or trash near
Rodents can detect food from a considerable distance. Pick up the trash in your garage, attic, and yard.
