They are back

Tonight just back from Germany I was getting the house ready for my visitors (Joy and Yann!!!) and while moving things around here is what I found:

Just to give you an idea the metal bar is 4 cm wide...
Every year comes September I'm invaded by spiders, huge ones. Nobody believes me when I say huge because I'm scared like hell of them so people think I exaggerate. But see!!!
I managed to kill this one only to see another one running around :(
Spiders are back, that's for sure. 2 months of stress ahead of me, checking every corner and every wall when I enter a room...
