Common entry points for pests

Common entry points for pests

We have discussed in previous blog posts how improperly sealed homes are prone to insect problems. What are the most common entry points for pests?


Your doors bring both invited guests and uninvited pests into your home! Take a few minutes to inspect all exterior doors in your home to make sure they are tightly sealed. Run your hand along the door seams. If you feel a draft, you don’t have a tight seal. The same is true if you can see daylight peeking through the door’s seams. A well-fitted door will block all light and drafts. Adjusting the anchoring of your ill-fitting door can save you pest problems and improve the heating/cooling efficiency of your home. Weather stripping and door sweeps can be added if you are unable to adjust the door. 

Poorly sealed windows

Ill-fitting, improperly sealed windows or torn window screens serve as common entry points for pests. Feel for drafts around your windows, sealing the exterior of window frames with weather stripping or caulk as needed. Thoroughly inspect all window screens, repairing or replacing any with tears. Even a small tear in a window screen compromises its function. 

Foundation and attic vents

Most houses in the Raleigh area have crawlspaces rather than basements. These crawlspaces are subject to moisture problems, so foundation vents are added to help the homeowner keep moisture levels low. Proper foundation vents can be opened or closed, depending on the season. If yours are broken, consider replacing them. As you have read in many of our blog posts, elevated moisture enables pest insects (including termites) to thrive. Foundation vents should also have tight seals around their edges and intact screening. While you’re checking your foundation, make sure your crawlspace door is tightly sealed as well. 

Many homeowners forget that their attics also have vents. Make sure screens and seals are tight to prevent insect and wildlife entry. 

Wire penetrations

If you walk the perimeter of your home, you will find locations where wires (cable, phone, electrical, etc.) enter your home. If there are any tiny gaps between the drill holes and these wires, insects can enter your home. Thoroughly caulking around each wire where it enters the wall will prevent insect entry at these points. 


Just like the wire penetrations for your electricity and cable, your heating and air conditioning system has entry points into your home. Ensure all entry points for control lines, suction lines, and duct work are properly sealed. 

By taking the time to inspect and repair your home, you help to ensure you get the most out of your pest control treatments. Together, we can keep your home pest free!
