Keep the Mouse out with Passive House!

Keep the Mouse out with Passive House!


We all love saving money — that’s a given — and being able to save hundreds of dollars a year on heating and cooling expenses with your Passive House is great. But there’s so much more to it than just saving cash! It’s about sanity. It’s about peace of mind. It’s about tightly sealed homes that keeps the four, six, eight, and 100 legged critters and creatures out.





Let’s talk about rodents and bugs: mice, centipedes, spiders and creepy crawly things. Not to mention rats and other burrowing creatures. My friends all know that I have a serious phobia of bugs and anything that could bite or nibble on me. Maybe it all started years ago when I saw a spider in my bed, coming out of the bottom of the duvet. Or when I was eight years old and stepped on a mouse in the dark utility room, accidentally killing it. If you’re like me and just the thought of these pests entering your home freaks you out, you’ll be happy to know Passive House provides a real preventative solution.


According to my very wise husband, these pesky creatures are initially attracted to the heat that escapes out of traditional homes. So when the temperature begins to dip, these furry little dudes look for a comfortable place to stay and will scurry around houses until they feel warmth and then start to burrow in! That is absolutely not acceptable. Passive House, to the rescue!


A Passive House, by its very nature, needs to be airtight and sealed, with thick walls and no heat loss – created by layers of wood, membranes, and insulation all tightly packed together. With no heat escaping the house, there is no desire for any mice to even think about digging into your walls. And even if they did get that wild idea, it is much more difficult for a little creature to make a hole in a 16-inch wall than it is in a draughty, leaky, traditionally built one.


I am seriously looking forward to moving into our bug and rodent-free Passive House – as long as my dog doesn’t bring in any bugs clinging to her fur, and any don’t sneak in through my hair, all will be well.



As always, check out where we explore more about the other benefits of Passive House and show you photos of our latest project.
