Mice how to get rid?!!!

We keep our house CLEAN!! I’m a clean freak okay so that’s not the issue... i don’t know what to do! I have a toddler and am pregnant I don’t want us getting sick from these nasty things we have traps everywhere. Different types too and even tried a tad bit of peanut butter on some. We caught one but still have one or multiple idk hoe many running around! I’m sick of constantly finding their poop on our belongings and seeing them running it’s going to give me a heart attack 🤦🏻‍♀️ exterminator isn’t an option. It’s been two months now and it’s so upsetting because we just moved in our home in April and almost everything is new in it our carpet, furniture, floors, like everything we replaced and it’s getting walked on and peed/pooped on by nasty rodents... we also tried sealing a couple areas where we thought they could been coming in from.
