Aurora’s Urban Rodent Rise: How to Seal Your Home This Season

SPLAT! Pest Management • May 24, 2026

Residents throughout Aurora, Colorado, are noticing an uptick in unwanted rodent visitors, and for good reason. Urban development combined with fluctuating weather patterns is driving mice and rat populations from their natural hiding spots straight into Aurora’s homes and businesses. 


Whether you live near the bustling Southlands, in a single-family home near Del Mar Parkway, or operate a commercial property along Havana Street, safeguarding your property against persistent rodents is more crucial this season than ever before.


Why Aurora Is Seeing More Rodents


Population growth and ongoing new construction in the Aurora and greater Denver metro area have disturbed long-established rodent habitats. These changes force rodents to seek new food sources, shelter, and nesting grounds, often leading them directly into residential and commercial properties. Food waste, accessible entry points, and mild winters only compound the problem, giving rodents every reason to stick around.


Key Signs You Have a Rodent Issue


Spotting a single mouse may not seem like a big deal, but it often means there are more lurking nearby. If you recognize any of the following, it’s time to act:


  • Droppings under sinks, in pantries, or behind appliances
  • Scratching sounds inside walls or ceilings, especially at night
  • Chewed packaging, wiring, or wood 
  • Oily smudge marks along baseboards or walls
  • Unpleasant, musky odors in enclosed spaces.


Sealing Your Home: A Step-by-Step Approach


Rodents are adept at squeezing through tiny openings—some as small as a dime. Sealing your home is your first and most effective line of defense. Here’s how Aurora homeowners can keep rodents out:


Inspect Key Entry Points 


Carefully examine your home’s exterior for vulnerabilities. Focus on these areas:


  • Gaps around doors and windows 
  • Foundation cracks and utility pipe openings
  • Unscreened vents and attic access points
  • Garage doors and basement windows.


For added protection, schedule a professional inspection from SPLAT! Pest Management to identify rodent entry spots that are easily overlooked.


Seal Openings With the Right Materials


Not all sealants are created equal, and rodents are notorious for chewing through expanding foam and lightweight caulk. Here’s what works best in Aurora’s climate:


  • Steel wool for stuffing small holes
  • Metal mesh or hardware cloth for larger gaps
  • Exterior-grade caulk and weatherproof sealant for cracks
  • Door sweeps for exterior doors
  • Heavy-duty vent screens, preferably metal.


Don’t forget to trim trees, shrubs, and landscaping away from your home’s perimeter—overhanging branches and dense bushes make for easy rodent highways.


The Importance of Seasonal Maintenance


Late spring and early summer in Aurora bring increased rodent activity as animals seek cool, sheltered spaces during warmer weather and after seasonal rains. While residents are prepping yards or enjoying the Cherry Creek State Park, make it a priority to:


  • Store outdoor grills and pet food in sealed containers
  • Clean up fallen birdseed and fruit from the yard
  • Secure trash bins with tight-fitting lids
  • Check for water leaks that might attract thirsty rodents.
