How do I improve the quality of my pears?

We have an old pear tree, loads of pears this year. We never prune it, as it grows very slowly.
I have no idea what variety our pears are, they are very large and usually aren’t ready until October/November.
Apparently you should pick the pears just before they are fully ripe and let them ripen indoors. Maybe you should pick yours now before the insects get them.
