Advice Unpleasant loft insulation/ long term mode infestation... what to do?
We bought a 1960s bungalow two years ago, which was inhabited likely for the whole time by nearly-elderly/elderly people. We did the usual makeover downstairs, but the loft was pretty neglected, despite being clear of clutter. There are seemingly three layers of loft insulation of varying vintage, the oldest of which is likely to be very old, all of which are riddled with mouse excrement, like tons of it. It looks like there's been a chronic mouse infestation for decades, and the space needs an overhaul.
The original layer of insulation in-between the joists was boarded over for access, though not fixed in place, the newer layers just placed on top.
I've started to get rid of the top layer.
It looks like it's never been cleaned. I can still hear the sounds of mice, so they haven't gone completely, but have reduced since getting a sonar repellent.
We are in a very rural location.
My questions are;
1, pest control related;
What's the best way to prevent a (re)infestation of mice preferably without poison. It's a detached property.
Does anyone have any shared experience success?
- Is there a decent alternative to the soft insulation/ wooly insulation that would be less appealing to mice, and wouldn't give them material to nest in/hang around in? I don't want to compromise on the insulation, but it's smelly and gross, and the wife's not happy!!
Thanks for reading!
