Clean your Bees, don't start a mite breeding hive.

New Project to Fight the Mite! : Treating Packages and Swarms

Summary: This Spring many beekeepers will be replenishing dead hives with packages. As all bees have some level of varroa mites, controlling mites in newly installed hives before brood is capped is key to ensure colony growth in the spring and summer. NY Bee Wellness, partnering with Beta-tec, maker of HopGuard II, will be conducting a program where beekeepers will treat their newly hived packages with either HopGuard II or oxalic acid, retreating in the Summer as needed, and in the Fall, and checked monthly for efficacy of treatments. This monitored trial is a first for the Northeast region. Similar trials have been done in the Southwest.


Beekeepers who are not directly involved in this program are also encouraged to treat their package bees, too, by doing the following:

  • Products of your choosing should be used before brood is capped, about 1 week after hiving
  • HopGuard II: Strips may be applied at the rate of one strip per five deep combs covered with bees in each brood super; see instructions HERE (page4).
  • Oxalic Acid: 5ml of oxalic solution per seam of bees, per instructions
  • Mite counts should be done about 2 days after treatment to determine mite levels, and monitored monthly for varroa levels.
  • Retreat in the Summer if varroa counts are >2%, and in the Fall after honey supers are removed
  • Beekeepers are also encouraged to treat newly hived swarms before brood is capped, hives that have swarmed and are requeening and splits- once the capped brood have emerged, or any time a brood break is initiated.

There will probably not be a better or easier time to treat than before the first brood is capped.

Here is a photo taken by a beekeeper of the ipm sticky board after installation of package bees in a hive. There is a lot of debris, such as bee legs, but most notable is the amount of varroa mites.

I strongly suggest that package and swarm installers treat before the brood is capped.

This certainly makes sense in order to get off on a good start. So here in Michigan, I'll be getting some nucs the first week of May. After getting them home and transferring them to their permanent single deep brood super to build up before adding the second deep, how long do you give them to settle in before hitting them with OA? Would you apply the OA while their still in the single deep, or would you wait until the second deep has been added?

Nucs are differant than a package you will have capped brood so you'll have to do at least 3 rounds of treatment a week apart OAV will not get the mites under the cappings. Start right away at treating don't wait.
