Indoor storage of honey bee colonies
​for winter is not a new idea, but it is rapidly becoming a more widely-used practice, with many potential benefits to explore.

This Guide to the Indoor Storage of Honey Bee Colonies in the United States was developed and created as a part of the Healthy Hives 2020 Initiative to provide an overview of best practices and scientific information for beekeepers who store their colonies indoors or want to learn more about this management option.  ​

INTRODUCTION

BY DR. BRANDON HOPKINS
Beekeeping is uniquely challenging profession; one that seems to only grow in difficulty as agriculture and land use continues to change to serve a growing human population. The introduction of Tracheal mites, Nosema, and the notorious Varroa mite (+ viruses) have only amplified the struggle. One of the earliest records of storing colonies indoors is a letter from a beekeeper describing annual winter losses of 30% of his colonies...

HANDLING AND PREPARATION OF COLONIES STORED INDOORS:  THE "INS" AND "OUTS"

BY DR. BRANDON HOPKINS
While this publication is intended to provide some information on storage conditions and information on the buildings used for storing bees; that information and management is relatively very simple compared to the months of work preparing colonies before placing the hives in a building​...

TYPES OF INDOOR BEE STORAGES
AND GENERAL REQUIREMENTS

BY: ANTHONY MOLITOR 
Bee storages can take on many different forms. In the Treasure Valley of western Idaho and eastern Oregon, beekeepers have used everything from existing bulk potato storages, old onion crate storages, cinderblock buildings, or any structure where forced air can be introduced to the hives. Thus far, there is no right or wrong answer to which style of building is best...

MODULAR COLD STORAGE

BY: CHELSEA COOK & KIMBERLY DRENNAN
To meet the specific needs of beekeepers while optimizing the health, security, and comfort of their honey bees during difficult times of the year, there are modular cold storage options available. Modular cold storage solutions put beekeepers in control; they are an option for beekeepers who want to avoid the stress of transportation or risk of large cold storage facilities.​

THE ECONOMICS OF HONEY BEE MANAGEMENT 
​And Overwintering Strategies for Colonies Used to Pollinate Almonds

BY: GLORIA DEGRANDI-HOFFMAN, ET AL. 
Commercial honey bee colonies are an integral part of agricultural production in the U.S. Each year, hives are moved across the country to pollinate crops that generate billions of dollars to the agricultural economy.

DEMOGRAPHICS OF INDOOR STORAGE

BY: KELLY KULHANEK, BRANDON HOPKINS, AND GREGORY SHVED 
The popularity of indoor storage is rapidly growing among US commercial beekeepers. As recently as the last 2-3 years, more beekeepers have adopted indoor storage as an overwintering strategy.

WINTERING STRATEGIES FOR
​THE BACKYARD BEEKEEPER

BY: KELLY KULHANEK
As indoor wintering of colonies becomes increasingly popular among commercial beekeepers, smaller beekeepers have naturally become curious about what benefits indoor storage may provide them.

CDFA PRE-INSPECTION PROGRAM

BY: KELLY KULHANEK
As trucks approach a California border station, they have to pull over to have their loads inspected for invasive species the state of California wants to keep out. The California Department of Food and Agriculture (CDFA) began a new program in 2018 designed to make the trip a little smoother...
