A recent survey reveals a disastrous 62% die-off of commercial honey bee colonies in the US between June 2024 and January 2025, the largest on record, following a 55% loss the previous winter. The culprit is bee viruses spread by parasitic mites, with every screened mite resistant to amitraz, the last effective miticide. The discussion highlights that commercial beekeeping practices, like shipping hives across the country for pollination, contribute to the spread of pesticide-resistant mites. Some suggest shifting to local beekeeping with more genetically diverse hives. Others bring up monoculture farming and overuse of pesticides as underlying issues, stressing the importance of supporting native pollinators. Some commenters call for a change in how agriculture is practised in the US, specifically advocating for regenerative farming techniques and less emphasis on chemical usage. Several alternative mite control methods like oxalic acid, formic acid, and brood control are mentioned, along with the potential for breeding mite-resistant bees.
