Seal the Gaps: The Easy Weekend Project That Keeps Bugs Outside Where They Belong
If you've ever spotted a trail of ants in the kitchen or found a spider making itself at home in the corner of your basement, you're not alone. Summer is when many insects are looking for food, water, and shelter—and your home checks all three boxes.
The good news? One of the most effective ways to keep bugs out doesn't involve sprays or traps. It starts with sealing the tiny gaps they're using to get inside.
Spend an hour this weekend inspecting your home's exterior, and you could prevent months of unwanted visitors.
Where Are Bugs Getting In?
Most insects don't need much space. A gap the width of a credit card—or even smaller—is enough for many pests to enter.
Pay special attention to:
Window frames
Door frames
Utility pipes entering the house
Outdoor faucets
Dryer and bathroom exhaust vents
Cable and internet entry points
Foundation cracks
Garage door edges
Step 1: Check Your Weatherstripping
Open and close your exterior doors.
If you can see daylight around the edges or feel warm air coming in, your weatherstripping may need replacing.
It's an inexpensive fix that helps keep out both bugs and drafts.
Step 2: Inspect Caulking Around Windows
Walk around your home and look for cracked, peeling, or missing caulking.
Fresh exterior-grade caulking helps seal out moisture, insects, and even improves energy efficiency.
Step 3: Check Window and Door Screens
A tiny tear can become an open invitation.
Repair small holes with a screen repair kit, or replace damaged screens before peak bug season continues.
Step 4: Trim Plants Away from the House
Trees, shrubs, and vines touching your home create natural bridges for insects.
Keep vegetation trimmed back at least 12–18 inches from your siding whenever possible.
As a bonus, improved airflow can also help reduce moisture around your foundation.
Step 5: Eliminate Food Sources
Even the cleanest homes can attract pests.
Remember to:
Store pet food in sealed containers
Wipe up spills promptly
Empty indoor garbage regularly
Rinse recycling before storing it
A crumb today can become an ant parade tomorrow.
Common Mistakes
❌ Spraying around the house without addressing entry points.
If bugs can still get inside, you'll likely be treating the same problem again and again.
Prevention is almost always more effective than reaction.
Charlotte's Tip đź’ˇ
Pretend you're the size of an ant.
Walk around your house looking for every tiny opening where you might sneak inside. It sounds silly—but it's exactly how you'll find many of the places insects are using.
Your home doesn't have to be airtight, but it should be bug-smart.
