A small trap like this from WalMart would be large enough for 8 week old kittens:

If you have any outdoor supply or farm&ranch feed stores, they will also carry traps.
You may be able to borrow a humane trap from your local shelter for a refundable deposit.
Or you may have some materials to build a manual drop trap. You do have to be watching. There is a rope tied to the wood holding the trap up which you have to pull for the trap to drop.
