I have a funky concrete pad outside of my garage side door that has a gap underneath it. There’s a hole on the side that has allowed some possum to move in. I counted at least 3 youngins and I thought I saw the momma just after sunset today.

What’s the best way to go about removing these? Trap one by one and seal hole afterwards? Looks like the young are old enough to move about, so I’m not too worried about one getting stuck underneath - but if anyone has experience removing possum I would appreciate your advice!

Video for context. And if these guys were elsewhere on my property (I live deep in the woods) I wouldn’t worry, but this abuts my home and I don’t exactly know with 100% certainty that they can’t wriggle in somehow.
