I am trying this, I think it works...
every night walking home along the corridor, the lizards running around and jumping down to escape....some hide at the edges of the gate waiting to slip in when I open the door.
So i print 2 big lizards with a color printer and stick it at my gate.... so far didn't see any lizard around for the past 2 weeks.....
but at first it does scares my sister
now these two lizards picture are my 門神
