8 Tips to Prevent a Rodent Invasion in Stamford, CT

Being both persistent and resourceful, rodents are some of the most difficult pests to remove. Once they find a way in, they will fight tooth and nail, (and, uh, whiskers), to stay in your home. 

But, your home doesn’t belong to them (as much as they’d like to believe that). 

So, what are ways you can prevent rodents from ever entering your home in Stamford? 

Start Prep in Early Fall

Rodents tend to move indoors when temperatures begin to drop in late September and early October. While you might welcome the autumn chill and look forward to the beautiful New England fall leaves changing, rodents welcome themselves into your home. And they aren’t very nice house guests. 

So, the best thing you can do for your home is this: start rodent prevention early. Because if you wait until rodents are active in your home, it’s already too late for prevention. 

Know What Rodents Look For

Your home has everything a rodent could ever need: warmth, food, and shelter (and, of course, an opportunity to enter it). 

Around Stamford, here are the usual rodent suspects to look out for: 

  • House mice and white-footed mice - both of these can fit through a gap the size of a dime. 
  • Norway rats - while these are larger than mice, they only need a half-inch gap to enter your home. 

Seal Any Gaps

Walk around your home and look for any cracks, gaps, or crevices a rodent might be able to squeeze through. 

Look for: 

  • Water lines
  • Gas lines
  • Electrical conduits 
  • Cables
  • Dryer vents
  • AC line sets
  • Foundation (don’t forget to check the sill plate)

More often than not, these areas provide gaps large enough for rodents to enter (and start taking long-term residence in your home).

Seal the Doors

Crouch down and look at the bottom of each door that leads outside. If you can see daylight seeping through, the space is large enough for a mouse, too. 

Here’s how to help: 

  • Add or replace door sweeps
  • Check the weatherstripping (it might be brittle)
  • Pay close attention to the garage door seal

Screen Your Vents

Vents need airflow, so don’t block them off completely. So, you can screen them instead. This way, vents still get the airflow they need and it keeps rodents from entering. 

Here are a few areas you can screen to keep rodents out: 

  • Foundation vents 
  • Dryer and exhaust ports 
  • Gable vents 
  • Soffit openings 
  • Roofline junctions 

Protect Your Food

Here are a few ways to protect your food from rodents: 

  • Consider moving pantry goods from cardboard boxes to airtight containers (glass, hard plastic, or metal). 
  • Seal up pet food as well (this is a main draw in the garage)
  • Frequently clean up crumbs under appliances 

Keep Trash Cans Away From Your House

It helps to keep garbage, recycling, and compost as far away from your home as possible. This way, you remove that open invitation for rodents to eat your scraps and find a way inside. 

Check Out Your Yard Conditions

Rodents usually examine your yard first. If there are easy areas to camp out, they’ll stick around until they find a way inside.

Here are a few ways to make your yard less attractive to them:

  • Keep woodpiles away from siding 
  • Clear brush, leaf litter, and debris piles
  • Trim ground cover and shrubs back from the foundation 
  • Cut overhanging branches back from the roof

Consider Professional Rodent Control to Help Take Your House Back

Rodents love your neighbor’s property, too. So, while you can’t control what your neighbor does, you can control what you do about rodent control this year. 

And, you might be doing all the right things to keep rodents away, and yet, they keep coming to your home. You might already be seeing and hearing: 

  • Droppings along the baseboards
  • Gnaw marks
  • Grease smudges on walls
  • Shredded insulation 
  • Scratching in the walls and ceiling at night 

All of these signs mean rodents are alive and well in your home. Meaning, it’ll be difficult to remove on your own.
