Looks more like a millipede. Millipedes always have two pair of legs per body segment, which is what I believe I see in the last image. Millipedes also coil themselves up routinely, and centipedes do not.

Unfortunately, millipedes will feed on small plant roots if they don't have ample sources of decaying organic matter on which to feast. Centipedes are predatory animals.

In my opinion, this would be a good situation in which to use diatomaceous earth (horticultural/food grade).

Rhizo, what does the Diatomaceous earth do? these plugs are fulled with a healthy mix of organic material.

Food/horticultural grade DE is very effective at scratching the exoskeletons of such critters, causing dessication. It would be especially successful with such young animals as your millipedes.

You'll need to address the bigger picture, however. Where did these little guys come from? Do you have a greenhouse (or similiar) where they are breeding?

If you are planting your sedum plugs outside in the real world, I don't think I'd worry about the centipedes too much. But in the confines of a greenhouse....

Millipedes, "thousand legged worms", generally cause so little damage to living plants that seldom does any control measure need to be taken, except in unhealthy soils. Since Millipeds prefer to eat decaying organic matter those soils that have ample quantities of OM in the soil generally do not see problmes with them.
