Advice on mice!

Recommendations for dealing with mice? We’ve had 3 over the past 6 months and spread very far apart so kept thinking it’s maybe a one off but getting a bit worried they might have bred. I’ve seen the council offer a service so not sure to go with them or if anyone else has experience. We’ve got 2 cats who are happy to do the catching but I feel like we should look at a professional option as we’ve got a toddler!
