TRUSTED PRODUCTS & PARTNERS
The Brands Behind Every Grizzly Install
We don’t install mystery material. Every Arvada project uses products from the industry’s most trusted manufacturers.
01THE PROBLEM
The Trail System Everyone Loves Ends at Your Garage.
Cherry Creek State Park, Big Dry Creek, Piney Creek, the greenbelts that sold the neighborhood also sustain the metro’s healthiest field-rodent populations. Every October the commute reverses: out of the grass, into the nearest heated structure. Traps meet them inside; exclusion meets them at the wall and wins.
AOctober is a calendar event here
First frost moves the field mice, and homes backing the greenbelts hear it first: scratching over the garage, droppings in the utility room. Sealing before October is the cheap version of this project.
BThree-car garages, thirty-foot doors
The wider the garage, the longer the door seals, and the more corners weather out of square. Garage-first entry is the Centennial pattern, and garage-perimeter exclusion is where our work usually starts.
CBuilder fill makes five-star bedding
Thin blown fiberglass is easy tunneling and warm bedding. One winter colony contaminates whole zones of it, droppings, urine, and a scent trail advertising the vacancy to next year’s wave.
DPoison in the walls is not a plan
Bait stations kill mice somewhere in your wall cavities and do nothing about the open gaps behind them. Exclusion first, cleanup second, deterrent insulation third, the order that actually ends the cycle.
02THE FIX
Seal the House. Clear the Evidence. Poison Nothing.
One crew handles what usually takes two contracts, the pest visit and the insulation repair, in a single scoped project:
03WHAT TO EXPECT
Sealed Before the First Frost, Ideally.
A Centennial rodent-proofing project, inspection to guarantee:
Garage corners, utility penetrations, crawl vents, and rooflines get walked inch by inch; the attic confirms species and traffic age. Photo map delivered.
Droppings, nests, and soiled fill exit through HEPA equipment in sealed bags, deer-mouse protocols throughout, no shop vacs, ever.
Steel mesh, metal flashing, and rodent-rated sealant close every mapped gap: garage perimeters, AC lines, vents, cantilever bellies.
Antimicrobial treatment neutralizes the pheromone signposts that would otherwise advertise your attic to next October’s arrivals.
Borate-treated cellulose rebuilds the insulation, then a final pass on every sealed point, with the photo set and guarantee in your records.
The Grizzly 100% Guarantee
If the work isn't right, we make it right. That's the reputation we've built across the Front Range, and it's our only sales pitch.

"Backing the Piney Creek trail meant mice every single October, three pest companies worth of traps. Grizzly steeled the garage perimeter, sealed eleven more gaps, and re-insulated with TAP. Two Octobers now, not a sound."

05QUESTIONS
Rodent-Proofing in Centennial, Answered Straight
Because the greenbelt is habitat and your house is winter shelter, a hundred feet apart. First frost triggers the move, and garages are the front door. It repeats annually until the structure itself is sealed, which is exactly what exclusion does.
Gap count, traffic history, insulation condition, and access set it. A newer home caught early is a modest job; a greenbelt-backing house with several seasons of history costs more and still undercuts the pest contract it replaces. Written line items before any work.
They manage population, not access. Bait also tends to kill mice inside your walls, with the odor to prove it, while the entry gaps stay open for the next wave. Exclusion closes the access; that is the difference between managing and ending.
We advise strongly against it. Colorado deer mice can carry hantavirus, and disturbing droppings with household vacuums aerosolizes the risk. HEPA filtration, respirators, and antimicrobial treatment exist for exactly this material, that protocol is non-negotiable for our crews.
Most Centennial homes are inspected, sealed, and cleaned within one to two days. Straight exclusion without cleanup often finishes in a morning. Photo documentation and the guarantee wrap up the final walkthrough.
Then the guarantee brings us back at no charge for any failure at a sealed point. In practice, steel and flashing do not lose to teeth, and a TAP-insulated, scent-neutralized attic removes the incentive, which is why we can make the promise in writing.
