I spray the grass around the bottom of my hives with glyphosphate. No issues at all with dead bees. I even mix pymethrin or bifenthrin in for hive beetle larvae control about every third or spraying.

My bees are located at my parents sod farm. I need to spray the sod for grub worms next weekend. There is nothing blooming in the sod grass so I’m really hoping I don’t impact the bees. I will just have to watch the wind direction.

Don't give up, don't ever give up!
