If you’ve ever noticed flying insects, such as wasps, flying around the exterior of your house, there’s a simple reason why – they’re searching for a warm place to take up camp during the cold winter months.
Sealing cracks and gaps with caulk and foam can be your first line of defense against insects by preventing them from entering into your home. You can use each one alone as a form a pest control, or combine with the use of bug spray or other insecticides if insects have already made their way indoors.
Keeping Bugs Out
The best form of pest control is to prevent bugs from invading your home to begin with. This can be done by eliminating their entry points. Sealing up cracks, holes, gaps, and crevices on the exterior of your home will increase the chances that your home remains pest free throughout the cold seasons. It’s important to caulk up even the tiniest of holes, since insects come in a variety of sizes, and smaller ones can squeeze in through even minor cracks.
Locate Potential Entry Points and Seal Them Off
The most common areas in the interior and exterior of a home that could contain gaps and cracks include the following:
- Interior pipes
- Roof trim and rafters
- Joints, siding, and sheathing
- Exterior columns
- Decks and porches
- Exterior pipes and foundation
- Doors and door frames
- Windows and window frames
You should use silicone caulk when sealing gaps or cracks that are smaller than 0.5 inches by 0.5 inches, unless you are using a backer rod. Silicone caulk should also be used when sealing cracks and gaps inside or outside the house, especially when involving applications that require flexibility due to joint movement. You should also opt for silicone caulk for applications that require fine, detailed work.
Foam should be used for holes and cracks larger than 0.5 inches by 0.5 inches, as well as for larger, harder to reach cavities. Foam should only be used inside where little to no moisture will be present. You should also opt for foam when you need insulation in addition to filling in cracks.
- Perform a thorough check around every corner, edge, door, light fixture and window. Go slow and caulk every single little hole or crack.
- Using caulk around window frames not only keeps bugs out, it also helps regulate the temperature inside your house.
- It’s recommended that you use caulk to seal joints.
- Clear silicone caulk is well reputed for its flexibility. It’s recommended for areas that won’t be painted over.
- Small cracks in your house’s foundation and siding can be patched up using caulk.
- Caulk should be used around exposed plumbing pipes, venting pipes, air intakes, sky lights, and exhaust grills.
It’s important to do a thorough check around the inside and outside of your house in order to ensure you’ve sealed up every last gap and crack. Remember, you don’t want any pesky little bugs sneaking through – so take the extra time to double check your entire house. With these proactive measures, insects will find your home next to impossible to penetrate.
