Easiest way to farm Crimson Key/Truffle Worms?

[Nutshell]

Is there a way of farming the Crimson Key or Truffle Worms?

BTW , I see 2 Truffle Worms but never catched it because I was so stupid not to have a Bug Net ^_^.

I stumbled upon this guide recently:

and was impressed by it's awesomeness.

This youtubechannel also has a key farm video.

For truffle worms, use Invisibility potion. This gives you an ability to stand right next to them!
For Crimson Keys, just build a typical afk farm in crimson. (remember about floating gross, it can pass through blocks.)
