I have plucked many of these seedlings out but, in some areas, they are so thick it is almost like ground cover. Is there anything I can spray on them to kill them? How can I prevent this from happening?
Unfortunately spraying will not work. Hand pull them as soon as they appear. Enlist the help of kids if you have them!
Seal the plants in a bag and dispose of. Do not put in the compost.
Mow the lawn regularly, regular mowing will weaken the the seedlings.
Dead head the mother plant and dispose of flowers so they can not seed.
You can also prune the mother plant in the early spring to reduce the number of flowers.
Here are a few links for you.

My rose of sharon is blooming now, thought it bloomed in August. Burning bushes are turning red. Rose of Sharon was trimmed last year, it leafed out but seems like it should not be blooming.
Rose Of Sharon will bloom from July all the way to September, depending on variety, pruning, growing conditions and environment.
Enjoy!

We planted a Rose of Sharon in our garden 2 years ago. Last year it bloomed. This year after a severe winter, the plant has 3 small leaves and nothing else. It gets partial sun and shade mostly.
Yes, that harsh winter may have injured your plant.
Continue care for your plant and I would top dress the soil with some good organic compost.
Wait and see is the best approach.
