Healthier air. Better efficiency. A stronger home from top to bottom.
In Bellevue — where homes range from mid-century builds in Bridle Trails to modern residences in Somerset and Newport Hills — both crawl spaces and attics feel the effects of our damp climate. Moisture, aging insulation, rodent activity, and temperature swings often start in these hidden areas long before homeowners notice musty odors, rising utility bills, or uneven room temperatures.
At Willard’s Pest Control, we help Bellevue homeowners protect their homes by restoring two critical spaces: the crawl space beneath your floors and the attic above your ceiling. By cleaning, sanitizing, removing damaged insulation, and installing high-performance new insulation, we improve indoor air quality, comfort, and energy efficiency throughout your entire home.

Crawl Space Cleaning
Bellevue’s moisture levels, shaded lots, and proximity to greenbelts make crawl spaces especially vulnerable to mold, odors, and pest activity. Our crawl space cleaning service removes contaminants that impact indoor air and overall home health.
What’s included:
- Removal of rodent nests, droppings, debris, and damaged insulation
- Full cleaning and sanitization of wood framing and subfloor
- Safe disposal of all contaminated material
- Preparation for new insulation and vapor barriers
A clean crawl space creates a healthier foundation for your home and prevents future issues from developing.
Crawl Space Insulation Removal & Installation
Many Bellevue homes — especially older properties in Lake Hills, Wilburton, and Crossroads — still have original or severely damaged insulation beneath the floors. Wet, chewed, or deteriorated insulation results in cold floors, drafts, and higher heating bills.
We handle the full process:
- Careful removal of old or contaminated insulation
- Bagging and sealing debris to prevent the spread of contaminants
- Sanitizing joists and subfloor
- Installing new, energy-efficient insulation meeting Washington State code
- Laying vapor barriers for moisture control
Improving your crawl space insulation can have an immediate effect on warmth and comfort.
Attic Cleaning & Sanitation
Rodents, dust, and aging insulation are common issues in Bellevue attics, especially in wooded neighborhoods like Clyde Hill or Medina. A dirty attic can spread allergens and odors throughout the home.
Our attic cleaning includes:
- Removal of debris, nesting, and contaminated insulation
- HEPA-level dust and allergen reduction
- Sanitizing structural wood
- Preparing the space for new insulation
Attic Insulation Removal & Installation
Proper attic insulation is one of the most effective ways to improve whole-home efficiency.
We remove old insulation that has been compressed, damaged, or contaminated, then install high-R-value materials designed for the Pacific Northwest climate.
The result:
- Warmer rooms in winter
- Cooler rooms in summer
- Lower heating and cooling bills
- Reduced noise and improved airflow
