When an animal is known for getting into our houses and making messes once they get in, it's easy for them to get a bad rap.
However, this doesn't mean that they don't have their own roles in the ecosystem, nor does it suggest we shouldn't care when they're threatened.
For instance, the last thing that most of us wanted as kids was for a bee to get into the house, but it's now immensely clear that saving them is a top priority for the viability of our future food stocks.
But while British conservationists aren't worried about that kind of catastrophe in this case, they're still putting a lot of creativity into protecting another of our little friends.
