You lock your doors, sweep your floors, and maybe even light a cinnamon-scented candle to keep your space welcoming and clean. But despite your best efforts, you’ve spotted signs—tiny droppings, gnawed corners, maybe a roach making a run for it when the lights flick on. Sound familiar? You’re not alone. One of the most common misconceptions we encounter at Action Pest is the idea that pest infestations only happen in “dirty” homes.
The truth is far more unsettling: pests don’t care how spotless your kitchen is. What they care about is access—and unfortunately, many homeowners unknowingly roll out the red carpet without realizing it. Knowing how pests get into your home is critical to stopping them before they settle in, multiply, and become a far bigger problem than you ever expected.
Let’s take a closer look at the most common—and surprisingly subtle—ways pests break into our homes and what you can do about it.
- The Sneaky Superhighways: Cracks, Gaps, and Unseen Openings
Pests are nature’s original ninjas. Mice can squeeze through a hole no larger than a dime. Ants? They’ll march right through a crack as thin as a sheet of paper. And spiders—well, they don’t even need a reason.
Foundational gaps, unsealed utility openings, and even the small space under your door frame are all potential pest gateways. Older homes are especially vulnerable, as natural wear and tear or settling causes structural shifts that open up small entry points around windows, basement walls, plumbing lines, and vents.
At Action Pest, our technicians have eagle eyes for these subtle vulnerabilities. We perform full perimeter inspections to locate, assess, and address entry points you didn’t even know existed—because when it comes to pests, what you don’t see is often what causes the most trouble.
- Open Doors—Literally and Figuratively
Let’s face it: we all do it. Holding the door open while hauling in groceries, leaving the patio door cracked for fresh air, or using a screen door with a tear “you’ve been meaning to fix.” While these seem harmless, they’re wide-open invitations to a parade of unwanted guests.
Flies, mosquitoes, spiders, and even raccoons will take full advantage of those fleeting open-door moments. Garage doors are another major offender—especially if your garage is cluttered with cardboard boxes and poorly sealed bins (which, to rodents, scream “home sweet home”).
Remember, pest prevention isn’t just about treating an existing problem. It’s about changing habits, upgrading seals, and installing preventative barriers to make sure the problem doesn’t start in the first place.
- Damaged or Missing Screens: Windows of Opportunity
When the weather’s beautiful, opening your windows feels like the right thing to do. But if your screens are damaged—or worse, non-existent—you’re letting in more than just a summer breeze.
Insects, particularly wasps, beetles, and moths, will take full advantage of those “window-shaped welcome mats.” Basement window wells are another overlooked vulnerability, often accumulating moisture and organic debris that attract pests like earwigs and silverfish.
Installing high-quality screens, routinely checking them for holes or tears, and keeping window ledges clean and dry are small but effective steps that make a big difference. Our Action Pest team often finds early-stage infestations in these areas during preventative inspections.
- Household Clutter and Cardboard Boxes—A Pest’s Paradise
You might think your storage room or basement is off-limits to intruders. But if it’s packed with old boxes, bags of clothes, and unused furniture, you’ve basically handed pests the lease to a cozy studio apartment.
Cardboard, in particular, is a magnet for cockroaches, silverfish, and even mice, who chew through it and nest inside. Termites may also be drawn to stored paper materials and boxes that touch concrete or soil.
It’s not just the storage room, either. Packages left on the front step, used furniture, and garage sale finds can also act as Trojan horses, bringing pests in with them. That antique couch? Might be harbouring bed bugs. That moving box? Could already have cockroach eggs inside.
- Pet Doors, Dryer Vents, and Unprotected Openings
Our pets deserve freedom and comfort, but unfortunately, their conveniences can open the door—literally—for much larger problems. Pet doors that aren’t sealed properly or don’t have locking mechanisms can let in everything from insects to raccoons.
Dryer vents, kitchen and bathroom fan vents, and even chimney flues offer easy access if left unprotected. Once inside, pests can make their way into your walls, ceilings, or attic before you ever realize something’s wrong.
Installing secure covers and metal mesh over these openings is a simple upgrade that prevents major infestations. These are often overlooked details—but they’re part of the comprehensive pest protection plans we offer at Action Pest.
You Can’t Block What You Don’t See—But We Can
