Physics then chemistry.
- This applies to many aspects of building science, but today I’m focusing on pests.
Why it matters: The next month is the ideal time to make sure your house is ready to resist the pests seeking refuge when it gets colder.
⚙️ How it works: Using physics means we are using the right physical barrier.
- Chemistry means we’re relying on a chemical barrier like sprays and repellents — this includes foam and caulk.
👉 A rat needs a 1” hole or a 1/2” gap.
👉 A mouse can squeeze through a hole the size of your pointer finger.
👉 A roach needs a gap the thickness of a penny.
📝 What to do next: Walk around the house and look at all the holes, cracks and crevices.
- Inspect every place a pipe or line goes into the house – HVAC, plumbing, electrical and internet.
- Close every gap and hole.
- Use metal – flat metal or tight mesh – where you can.
- If you find areas where animals have been chewing (usually squirrels), they’ll be back. Prioritize those areas.
- After you’ve done as much as you can physically, you can finish with caulk or spray foam.
