You can also choose to NOT spray harmful chemicals on your lawn/garden/landscaping. As a hobby beekeeper in a suburban area, I appreciate it when my bees are not bringing this junk back to their hive and my honey!
I'm not a botanist or anything. This is just what I've read. But I remember growing up there being clover everywhere. It was vibrant, green, felt great under foot and flourished even in South Texas.
You don't see that often anymore. The claim I've seen is that herbicides commonly used to treat weeds on lawns kill it.
So I bought a couple 1lb bags off Amazon (I think about $10). We had a few weeds since we don't use herbicides (not out of principle or anything, I'm just not that into gardening). Anyways, the clover chokes out the weeds completely, looks great, seems to help the grass grow better, and is just nothing but a positive thing.
Really happy with it. Some of my super-gardener neighbors might not appreciate it. It's never come up. But I like that even during droughts my lawn stays vibrant and green with minimal water.
In this particular case, it's your bees that are going onto the neighbors property and bringing back chemicals. Clearly you can't control the bees (unless you encase them in a dome) so it's not quite analogous to letting a dog roam around the neighborhood...
I'm very curious what would happen if e.g. you tried to sue your neighbor for harming your bees.
There are restrictions on herbicides that can be used in most residential areas, I doubt you are going to get a court to override those rules and give bees priority.
