We knew they had eaten the bedroom floor too but……. !!!!
That being said in a way it was a blessing (if borer eating your floor can be one) as having pulled up the carpet we noticed a damp patch (that bit of board shouldn’t be that colour)..and having pulled up the floor a burst pipe! So as I say a blessing in disguise.
Still all done now so no more tip toeing around the room afraid of going through the floor (never a good feeling).
