I called my States agriculture department and informed them that the pre-emergent in most weed control fertilizers is an extreme irritant to most Bees. I discovered this in my yard accidentally.
I had a large underground bees nest in one corner of my yard. On the other side of my yard I had several raised bed gardens. The years when I didn’t put preemergent down my garden had plenty of Bees pollinating their little hearts out. The years I put preemergent on the lawn the Bees would not fly over the fertilized areas!
Underground bee nest, you mean yellow jackets right?
