How to clean, disinfect, and reuse Primal Bee EPS hive equipment after an AFB infection.
A confirmed AFB diagnosis is one of the harder moments in beekeeping. With wooden hives, the standard answer has been to burn the equipment — which means losing the colony AND the gear in one stroke. The genuinely good news here: with EPS, you don't have to do that. Primal Bee components can be fully sanitized and reused. A proper bleach soak kills AFB spores and most bacteria, and your gear comes back into service safely.

Important: Always consult with your local beekeeping association or apiary inspector before proceeding with any AFB remediation — AFB is reportable in many jurisdictions and there may be legal requirements that apply.
Cleaning the hive before disinfection
Before applying any disinfectant, remove all organic material from the hive. Wax, propolis, and debris reduce bleach effectiveness and can shield spores.
Dismantle the hive equipment
If possible and necessary, freeze each component in a large chest freezer for at least 48 hours
Carefully scrape off all wax and propolis onto cardboard or newspaper
Burn the scraped material to destroy pathogens
Confirm all organic material is thoroughly removed before moving to disinfection
How to disinfect with bleach
Use household bleach (3–5% sodium hypochlorite) diluted to a 0.5% sodium hypochlorite solution. Soak all components for 20–30 minutes to kill AFB spores and most bacteria.
Tip: For one or two boxes, use a shallow tray and rotate each wall to ensure all surfaces get fully soaked.
Safety precautions
Protective gear — wear gloves, eye protection, and appropriate clothing
No mixing — never combine bleach with other cleaning products (toxic gases can be released)
Ventilation — work only in a well-ventilated area
Cool water for soaking — bleach breaks down faster in hot water
Hot water for rinsing — after disinfection, rinse thoroughly with copious amounts of hot water to remove all bleach residue
Air dry — leave components to dry outside in sunlight
Important: Always consult with your local beekeeping association or a professional before proceeding with any AFB remediation.
FAQ
Do I need to burn my hive if it gets infected with American Foulbrood?
No — and this is one of the significant advantages of the Primal Bee system over wooden hives. The EPS equipment can be effectively sanitized and reused; you do not need to burn it. Always consult with your local beekeeping association or a professional before proceeding with any AFB remediation.
How should I prep and clean the hive before disinfecting it?
Dismantle the hive, freeze components for at least 48 hours if possible, scrape off all wax and propolis onto cardboard or newspaper, and burn the scraped material. Make sure all organic material is thoroughly removed before applying disinfectant, as it reduces bleach effectiveness.
What is the proper bleach solution for sanitizing the hive?
Use household bleach (3–5% sodium hypochlorite) diluted to a 0.5% sodium hypochlorite solution for immersion. Soaking components in this solution for 20–30 minutes kills AFB spores and most bacteria.
How long should I soak the hive components to kill AFB spores?
Approximately 20–30 minutes of immersion in a 0.5% sodium hypochlorite solution. For one or two boxes, use a shallow tray and rotate each wall to ensure all surfaces get fully soaked.
What safety precautions should I follow when using bleach on the hive?
Wear protective gloves, eye protection, and appropriate clothing. Never mix bleach with other cleaning products, as toxic gases can be released. Work only in a well-ventilated area. Use cool water for disinfecting since bleach breaks down faster in hot water, then rinse thoroughly with hot water afterward. Leave components to dry outside in sunlight.
