Woodlice and sliverfish are very commonly found in houses even modern builts, Don't worry about them just chuckem outside for the duck/chicken to eat if you don't like em in the house.
Well the mouse man has come arround just now and declaired with all the bate that was in the traps that has now gone they would have been killed by it.
Which in one way is sad but inanother way i am happier nowing the house it mice free.
Now to hunt the wholes and fill, fill, fill ,fill ,fill, fill to stop the bugger getting in again!!!!
