One thing you might consider is checking your extensive roster for another toon with trapping skills.
I have one sitting there at level 10, from the Veteran III Event ( a tiny event from last year's anniversary, characters could start at level 10). He's Rogue 8 Cleric 2 and fits way better for that. His name is Artflam, and he is in the list :

I haven't played that one much within the last months.
Alrih was originally *not* intended to be a trapper ! - but instead as an experimental quarterstaff Thief Acrobat build. The Favoured Soul levels were meant to experiment with the "Favoured Weapon" from Aureon - the Quarterstaff.
Alrih just grew into that role as a trapper, but that was never intended by me.
As soon as you reach level 10, I might switch towards Artflam if you need a trapper. Alrih will remain my experimental Thief Acrobat, then. Just for fun.
The other possibility would be that I'd switch into another role, and someone else would be the trapper. In my list I have a few characters at level 8, for example Senha, a Sorc. She does have Favoured Soul levels as well, though.
Most of my characters are there for experimenting with builds. They are there just for fun. That's why I have only very few pure builds.
I could try out a pure rogue trapper as well, but Artflam was intended by me to be one (his Cleric levels were meant to be for survival - especially self-healing and remove poison / disease (Illness) ).
I have an Artificer sitting for many years at level 11. I don't even remember anymore what he was built for. (Aracaram)
The only other almost pure Rogue I have is meant to be an Assassin. (Tirinha)
