no idea on how to help, as the last mouse we had,

*bit barberric so dont read if weak stomached*
df cornered it in the kitchen between cuboards, my dog made sure it didnt move while df "delt" with it, big knife skewerd threw its back. never had a mouse problem since.


but what ever you do, dont trap him and the nrealese him in the park up the road! a friend did this as she couldnt bring herself to kill it, a week later it was back, with 5 others!

good luck and hope you get rid of it, cunning little things they are!
