You're so lucky! Wolves annoy me, they run after you, you can not avoid them, they're not really useful and at a decent level not a challenge any more. Plus i like wolves and do not like to see games were you've to mandatorily exterminate them...
But what you describe is weird. In my game they respawn after a game day or though...
The bandits on the other hand, sometimes take days to respawn.
There is a reason the bandits take a few days to re-spawn, as it would give you time to make a special elven wine delivery without any bottles being destroyed from battles.
Also if you have guards patrol those area's, the paths should be clear.. personally I'd save that extra expense and clear the area's myself
As for Wolves, if strong enough to win fights against 3 at the same time, go east/north of Family farm, which is strait south from town.
In this forest go up up up, kill everything along the way, or skip by moving fast around if ya want/can, but do kill the 3 wolves packed up halfway, go to end of the path, enter the cave, exit again and go down, all critters have re-spawn

If you have the family home, enter, sleep, repeat next day

This assuming you need the pelts ofc, noble creatures shouldn't be exterminated for the fun of it
