Mice are terrible! Nothing worse than trying to catch them yet hearing them in the walls as though they are taunting you.

Even exterminators will just set a ton of traps and keep changing them, so keep going with that if it's working. If you have an area outside you should do a bucket trap, with some water/anti-freeze (or something that won't freeze), it doesn't need to be reset with each kill. https://www.amazon.com/RinneTraps-Bucket-Outdoor-Compatible-Manufacturer/dp/B08SL6KJ29
