Yeah, I have seen them here!
They will never attack on their own.
But is they feel threatened, they will defend themselves the only way they know. Bite and hold, pumping slightly venomous saliva into their attacker.
apparently, is is very hard to get rid of them when they bite!
Yeah, they hold on. It’s a testament to how low-key they are that they need venom to subdue mice. Even in their warm climate, they brumate through the winter.
