You could try attracting more birds to your garden and see if that balances things out.
In spring you can sow more grass seed and perhaps go for a family mixture which is quite hardy. I would have thought that if grass has a healthy root system to begin with then it will be thick enough to cover worm activity, so maybe it's the health of your lawn you need to improve rather than seeing the worms as the issue.
