I recently lost a hive, in the last inspection I found some worker bees, no stored pollen, no honey, no brood, and no queen. How should I start this hive back up? Should I wait until the Spring to do so?

I recently treated my hives for Varroa mites with Apivar. How soon after taking out the Apivar should I test again for mites? Should I test all my hives? Should I use Apivar again right away if I find mites?
