hmmm scared off? I maybe scared all.
The problem is when I see them and I scared, my self-protection
mechanism will activate and I'll kill them all using pesticide then
flush them down the toilet bowl. 
As for lizards... I just leave them alone, cause till now i still
can't find a effective way to chase them out/kill them. They run
very fast.
So far, there is no insect that I see leave my room alive.
