The teenagers, who are aged between 14 and 19, were woken up by police just before 7am on at addresses in Margate, Broadstairs and Birchington.
They were interviewed at Margate Police Station about 995 offences of criminal damage in the Thanet area.
As well as arresting the young people, the 40 police officers involved in the operation seized various items from addresses including computers, note pads and other personal belongings.
The operation, jointly planned by Kent Police and community safety staff at Thanet District Council, follows damage to public and private buildings as well as in open spaces.
Mark Richardson, community safety manager for Thanet District Council, said: “This sends out a strong and clear message that graffiti done in this way will not be tolerated any longer. The district council has, and will continue to, work side by side with Kent Police to ensure that offenders are caught and dealt with.
“This is part of a targeted and prolonged effort by partners to remove graffiti, carry out enforcement against offenders and look at preventative projects to do it lawfully and without damaging anything.”
Police arrested two 14-year-olds, a 16-year-old and a 17-year-old from Margate; two 14-year-olds and an 18-year-old from Broadstairs and a 19-year-old from Birchington.
Ed: I'm delighted that the Police have taken action, given the appalling blight and cost that graffiti is causing to our community. The next challenge will be to see if the Magistrate delivers anything stronger than a caution, which is hardly an effective deterrent to the graffiti vandals of today.
