Treating New Package for Varroa?

[Sunnyboy2]

After reading "Simple Early Treatment of Nucs Against Varroa" (Oliver, American Bee Journal, April, 2013, pg 389) I have thought about the benifits of treating a package before installing them in a hive.  My thought was to sugar shake the entire package (minus queen) in an attempt to knock any varroa that may be on the bees.  This would also give a good base count of the parasite.  As a rule, I have tried to stay clear of chemical treatments, wishing to rely on more mechanical treatments and genetics.
In the artical Randy Oliver suggests that there is real benefit from early spring treatment , focused between old and new queens, when maximum mites are outside of capped brood.
My thought was "dosent that make a package the perfiect place to treat?"
Do you think any benifits from sugar shake out way potential problems (confusing new queen smell, dehydration, stress, ect)?
What about other treatments?
Any thoughts on this by the experienced Beeks?

A sugar dusting probably wouldn't hurt, other than annoy the bees. As for other treatments, keep in mind that many (most?) package producers treat the bees prior to making up the packages.

Ditto what Indy said.

Either you keep dealing with the mites for the bees, or you have to let them deal with them... in a year, it won't matter if you treated them now...

Mites are everywhere bees go.   Every flower that a bee lands on has the potential to carry a mite that fell off the bee that was on that flower earlier.   And just how many different bees hit a single flower in a day?

Sugar dusting does not help with varroa.

Simple way is to give oxalic acid trickling.
If packge bees are 2 pounds, 15 ml syrup is very good dosage.
