The Troll Security Service (TSS), also known as Norges Trollsikkerhets Tjeneste (TST), is a fictional service in the 2010 film Trollhunter. The service works on the basis of keeping Trolls a secret and protecting civillian areas from eventual Troll attacks and Troll territories.

Methods of troll controlEdit

The TSS' primary service is keeping Trolls away from human-populated areas. They do this by looking for signs of Troll activity in news and other forms of media and then go to that location. Should it be a Troll that has breached its territory then it is the Troll Hunter's job to kill the Troll. The only troll hunter seen in the feature film was Hans and although it it unknown whether he is the only hunter in existence, he is probably the only currently active hunter.

Killing a trollEdit

Killing a Troll is the only method of Troll control utilised. By exposing the Troll to a large dosage of UV light, the Troll's inability to convert Vitamin D will cause the Troll to either explode, if it is young, or turn to stone, if it is older. This causes inexplicable pain for the Troll.


A Troll hunter is left to make his own equipment for his job, but there is however some basic equipment they all have, like 'concentrated Troll stench' made of all the bad stuff you can get from a Troll, and the hunter must carry a 'flash gun' which sends out shots of light capable of killing an average size Troll.

Laboratory testsEdit

It may be needed that the hunter takes a blood sample of an individual Troll and brings the sample to a lab and find out if there's an eventual disease going on among the Trolls and how this affects the situation. In the 2010 feature film, it was discovered that rabies was spreading among Trolls.
