I noticed I have scuds in my hc that I have planted into my 10g where I'm currently doing the dsm(dry start method) to carpet them out. I don't have much water in there, substrate is moist enough to the point where you can't see any water lines. What should I do to kill any possible scuds?

from what I have read, they are good source of fish food. Some people would buy them as live food for their fish. But would be hard of get rid of once it is in your tank, if your tank does not have any other predators that would consume them.
There is pretty much no solution aside from breaking down the tank. The thing about scuds is that they LOVE to eat mosses, especially Flame, Taiwan and Peacock. Since you are doing a dry start I'd really get it dry but keep the humidity high...hopefully there are no puddles and the scuds will die. You can also add some Dario Dario or other similar fish in hopes of killing the scuds but they still might survive by hiding.
I just broke down my 10 gal shrimp tank because it was overrun with scuds. THOUSANDS of them. Ate all my moss. Caught them killing newly molted shrimp. That was the last straw. When I kept some cardinals and rasboras in there the population stayed way down but you'll never be rid of them entirely without adding copper or something. The fish ate my shrimplets as well as the scuds so that was no solution for me. In a fish only tank they shouldn't be a big problem. Tetras love them.
With a DSM, I would recommend a CO2 nuke. Cover the tank tighly and add in CO2 and asphyxiate them. Just be sure and remove any livestock you want prior. It is a technique I have seen a lot of dart frog keepers use when they accidentally get unwanted guests in their vivariums. With a fully aquatic system, I would remove shrimp/fish and lower water and perform as DSM.

If you're dealing with a ton of them, then yes, a CO2 nuke will work well, but you'll have to do it a few times to make sure any freshly hatched scuds also bite the big one.
Do you have any fish in the tank? A betta would make quick work of the adults. I actually found that a school of black neon tetras (serpae would work too, I'm sure) cleared up the problem very quickly.
