Give em both barrels Perry. Their inspection process sounds like a farce, you just can't pull the lid on all and do full spot check inspections on hives to declare a shipment beetle free.
The only reason the beetles are at the top is because they've been herded up there by the bees, otherwise they'd be down in the comb looking for a place to do their dirt to a hive. They're just like any vermin, if you see one it's a safe bet you've got ten or more.
