The Philadelphia Bomb Squad safely removed the suspected bottle bombs from the front of the teen's home, on the 2700 block of East Monmouth Street.
The devices were soda bottles filled with chemicals.
Investigators say they were badly made and not capable of exploding.
But the teen -- who does not wish to be identified -- told Action News that in the last couple of months similar bottle bombs have exploded outside his home.
He says the bombs started to show up after it was clear that he was going to testify in court on behalf of a friend.
The teen says he and his family have not reported the bombs to police until now, because they hoped they would be able to handle the situaiton themselves.
Neighbors confirmed to Action News that there have been explosions outside the house in recent months.
Police conducted a number of interviews early Wednesday morning but so far have not indicated if they have any suspects.
