I'm kinda new to seeds germination. I've been growing my seeds outside since September and ever thing seems fine until today. My seeds had been chewed on, some are dug up, and some are totally missing

All of the Eugenia seeds I gotten for free from Richard in this forum are all gone too. Who could have ate! They're just seeds with no flesh.
I'm very upset and now that I know I need to make a set up for seeds germination inside. But Idk where to start. ):


As you can see, something chew these. They're peanut butter fruit seeds

What left of my Eugenia seeds. All the other ones are completely missing from the cup
