Pest infestations often start from the outside in—small cracks, gaps, and openings around your home provide easy access for insects and rodents. If you’re serious about preventing pests, sealing these entry points is one of the most effective steps you can take.
At On Demand Pest Control, we know that South Florida’s warm climate attracts all kinds of pests year-round. That’s why sealing up your home’s exterior is a must for keeping roaches, ants, rodents, and other unwelcome guests outside where they belong.
Why Exterior Gaps Attract Pests
🐭 Rodents can squeeze through a hole the size of a dime.
🦟 Insects slip through even the tiniest cracks around windows and vents.
🏠 Unsealed openings give pests easy access to wall voids and hidden nesting spots.
By properly sealing gaps, you block entry points and prevent infestations before they start.

Where to Look for Pest Entry Points
Inspect the exterior of your home for these common problem areas:
1. Doors and Windows
- Install door sweeps on all exterior doors to block rodents and crawling insects.
- Make sure window and door screens are free from holes or tears.
2. Roof and Eaves
- Check where the roofline meets the structure—gaps in eaves and soffits are easy access points for pests.
- Seal overhangs and attic vents with durable screening to prevent rodents and insects from sneaking in.
3. Foundation and Siding
- Look for cracks where the foundation meets the ground—termites and ants love these spaces.
- Seal any gaps between siding panels to keep out small insects.
4. Utility Openings
- Gaps around pipes, electrical wiring, and HVAC lines can be an open invitation for pests.
- Use copper mesh, stainless steel wool, or caulk to seal these areas tightly.
5. Vents and Air Intake Systems
- Cover attic vents, crawl space openings, and dryer vents with screens to prevent entry.
- Install filters in air intake systems to keep flying insects out.
🚨 Grab a flashlight and do a quick inspection of your home’s exterior—you might be surprised at what you find!
Best Materials for Sealing Cracks and Gaps
When sealing your home, use materials that are durable and pest-resistant:
✅ Silicone Caulk – Great for sealing small cracks and gaps.
✅ Copper or Stainless Steel Mesh – Ideal for stuffing larger gaps, especially around pipes.
✅ Expandable Foam – Fills gaps but should be paired with steel wool to deter rodents.
