I noticed here in South Florida...
Dead bees. In my back yard are MANY varieties of flowers. I’ve never seen what I see lately. Dead bees. I don’t use preside either.
I have three large Jasmine trees which are about 20’ tall. Each month when they bloom you can smell them 5 houses away. When in bloom the sheer volume of bees flying through those trees makes a buzzing and humming sound that is heard throughout the yard. In only one bloom outbreak have the bees been swarming.
Too often I sit out with my coffee and have a bee fly nearby, land in some clumsy fashion, walk oddly for a foot, curl up and die. I’ve never seen this before.
I will say that 5g is being installed by AT&T in this area. Not sure if it is related, but worth mentioning
I’ve heard that possibility mentioned before (back when the honeybee depopulations first started making the news.)
Sound & light pollution, loss of contiguous habitat, etc. Hard to quantify, but lots of potential challenges for the wild things.
5G uses pretty much the same frequencies and same power levels as previous generations of cellular technology. If I were to guess, I’d say the likely culprit is the large scale use of pesticides. You may not use any pesticides, but I bet your neighbors do. And if they don’t, I bet the farm up the road does.
Bees need a lot of water and will always seek the closest source. If that water is contaminated by roundup, fertilizer, or any pesticide it will affect the entire colony.
