This was an Italian movie from the 60s or 70s that I saw about 30 years ago on late night tv when the stations would show old movies. The only thing I remember about it was a guy who was tormented by flies and birds every time he went outside. He finally trapped a fly in a phone booth with himself and filled the booth up with bug spray which knocked himself out. I don't recall much dialogue in the movie. Anyone know the name of this film ?
