Call me a weirdo, but I have a theory about the effects of the electromagnetism of the 4 and 5G. Bees work using static electricity and I haven't researched international hive health around this, but I think there could be a correlation. If you look here and add your/any required location https://www.vodafone.co.nz/network/coverage/
you can see the extent of coverage in your area. If I'm right, your hives in areas with lower coverage will be healthier. If I am, it's also a scarey prospect for future beekeeping.
Weirdo or not, I'm intrigued about the results![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
