Thrips are very mobile and not around when you are looking for them. So any sort of kill on contact pesticide will miss them. Not sure if neem has any sort of residual effect? Personally I would go with a systemic like Orthene, but I don't have to deal with an indoor terrarium. Nepenthes are pretty tolerant to most chemicals so I would just go to the hardware store and find a general purpose insecticide that is non oil based and will work on thrips. If it isn't a systemic type then be sure it has a week or two of residual control after application. Also refrain from misting.. you don't want to wash the pesticide off. Plan on 2 or 3 treatments a couple weeks apart or so.
Is that a Nepenthes in your pocket or you just happy to see me?
Grand Hotel... always the same. People come, people go. Nothing ever happens.
I second Orthenex, I've used it in the past with excellent results. Also may want to look into a fungicide, I agree with Tony, I see some other potential issues.

Thank you for the recommmendations everyone! Hopefully I can stop these buggers!
These seedlings ahve been growing slowly for the past year, until a few months ago where they started speeding up. I noticed last week they've been turning bronze-brown colour from green, i don't think its due to light since ligh levels haven't really changed. Anyone have any idea if anything is wrong or is it just me? Could this be caused by overly wet media?
Media degradation was in my mind aswell, also the media has been staying more wet lately, I guess I should go ahead with repotting them as had thought. Now, to see if I have any media
late to the table here , but do you have good air circulation, Add a fan, it will help cut down on overly wet leaves,
it does look a bit damp in the grow area, are these in a tank or in the open air , crowding can be a real problem can you move the plants a few more inches apart, or to another grow space.
i grow in a terrarium almost exclusively, and have to watch out . for the same kind of problem, IMO its the damp conditions , especially if you see no bugs, but dont rule them ou, t i would still do what tony has suggested. it cant hurt.
