All the time. They can walk around barefoot in the nice grass without stepping on all sorts of bad things. Also, you don't use glysophate on the grass... That would kill it. 2,4-d is the general purpose broadleaf weed killer used on turf. Glysophate kills everything. It's for the sidewalk cracks and bush beds where the mulch didn't surprise weeds and there are too many to pull or the pinestrae sideyard that has a ton of weeds pop up every now and then. A well maintained front yard doesn't need many chemicals. If the grass is healthy, you don't need to put anything on it except preemergent twice a year. Pre emergent only stops seeds from germinating.

I know my grass, chemicals and nature and I love my wildlife and garden. As with all things there is a balance. A yin and yang. All weeds and no turf just as bad as all turf and no weeds. This trend of hating on yards can actually serve to harm the environment as it lets invasive species take over. We as humans have a responsibility to take care of our environment and that means maintaining part of the environment and preserving native species.

Without maintenance our world would be all hogs iguanas fire ants, kudzu and dandelions. No diversity.
