Had a conversation with a friend from the phils the other day on yahoo (not Rizza) and she told me of a lady she once knew who was from a family of suspected Aswangs B)
So I hit good old wikipedia before and found this wonderful little tip here for dealing with Aswangs....
"Throwing semen at aswang is also said to irritate them."
oh dear, I havent heard that before..when I was a bairn my great grandmother used to tell me that they are afraid of garlic and salt...
