Meet Maple, a retired State of Michigan K9 who has gone from sniffing out criminals to sniffing out a highly contagious and dangerous bacterial disease that affects bees and can wipe out entire colonies if not detected fast enough.
Maple was retrained using her police detection instincts to sniff beehives for American foulbrood (AFB). AFB is an aggressive bacterial disease that only hits the larvae, the young developing bees and not adult bees. Once spores get into larval food, they multiply rapidly inside the gut of the developing bee, killing it after the cell is capped. The dead larva turns into a ropy, glue-like mass that dries into a hard scale, containing millions of spores. Those spores can survive for decades, spreading from hive to hive via bees or contaminated equipment.
AFB doesn’t “poison” adult bees, but it turns them into unknowing carriers. As more brood dies, fewer young bees hatch to replace the aging workers, and eventually the colony collapses. There’s no cure, once confirmed, infected hives and equipment are destroyed by burning to stop the spread.
That’s where Maple comes in. Wearing a specially designed canine beekeeper suit, she can rapidly move through an apiary, sniffing dozens of hives in minutes, something that would take a human inspector hours or even days. When Maple detects the telltale scent of AFB, she alerts her handler by sitting in front of the infected hive, allowing for swift action before the disease spreads further.
With honeybee populations already under severe stress from disease, pesticides, pests, and poor nutrition, Maple’s work is helping protect not just bees, but also the crops and ecosystems that depend on them. Her new mission (in her SpaceX like suit) proves that even after retirement, a good dog’s nose can still serve and protect. This time, saving an entire species one hive at a time.
