Pest Control Insulation Commerce City, CO

Commerce City sits at 5,164 feet elevation on open plains, with neighborhoods like Irondale, Derby, and North Range Village directly adjacent to agricultural fields and the Rocky Mountain Arsenal National Wildlife Refuge. That proximity creates constant rodent pressure — mice and voles actively seek warm attic and crawl space cavities as temperatures drop toward the January average low of 17°F. Standard fiberglass batts offer zero deterrent. TAP insulation, treated with EPA-registered borate compounds, kills insects on contact and discourages rodent nesting, while simultaneously meeting IECC Climate Zone 5’s R-49 attic minimum.

Most Commerce City attic projects using TAP insulation or dense-pack cellulose range from $1,800 to $4,500 depending on square footage, existing contaminated insulation removal, and the extent of air sealing required. Xcel Energy — the primary utility for most Commerce City ZIP codes — offers rebates up to $600 or 60% of project cost for qualifying attic insulation and air sealing work performed by a registered contractor. United Power members in the northern sections may access additional efficiency rebates. Level Up Insulation Co. is a registered contractor eligible to process these rebates on your behalf.

The process starts with a full attic and crawl space inspection to identify contaminated insulation, active pest entry points, and current R-value loss. If existing material is compromised, it’s removed and disposed of before any new installation begins. Air sealing comes next — closing attic bypasses, rim joist gaps, and penetrations using closed-cell spray foam before insulation is applied. TAP insulation is then pneumatically injected or blown in to achieve the target R-value. Blower door testing can verify the building envelope improvement, measured in cfm50, before the job is closed out.

Key indicators include visible rodent droppings or nesting material in the attic, a persistent musty or ammonia odor, unexplained spikes in heating or cooling costs, and insulation that appears matted, tunneled through, or discolored. In older Derby and Irondale homes, moisture-damaged insulation is a particular concern — wet cellulose or fiberglass loses R-value rapidly and actively attracts carpenter ants seeking softened wood. Freeze-thaw cycling also widens foundation cracks, creating new entry points each winter. If you’re seeing any of these signs, schedule an inspection before the damage compounds further.
