You have to close up all points they can infiltrate. screens, spray foam. Snap trapshave to be set correctly, and there are other lethal traps, there is one I havent tried that is expensive but less than your quote that is highly reviewed, and there are the standard batter powered ones they walk into and get zapped, I have used those and they can work well, the batteries must be changed often if rats set them off. https://www.amazon.com/gp/product/B0CC9JF6PV/ref=ox_sc_saved_image_4?smid=AD0XBU34DLMIS&psc=1
To get into your walls means that you should go into your attic and close off all openings to the top of the walls. Move your insulation over temporarily to do so, this will also increase your energy efficiency alot by closing off air infiltration paths. You can also then vacuum and wash off woodwork from having mice as breathing all that for the rest of your time in the house is non-ideal. Then, go under the house and look for any spots, in my house it was plumbing penetrations under the house that were the access points for rodents and tarantulas. I used spray foam. Then I made sure all opening to the under house area were also appropriatelly closed off. Screens fixed and spray foam corners and a new access door.
Go ahead and kill them before closing off access, because.... what if your direct killing methods dont work, then, and only then, you will need to put out a poison. This depends on type you can buy, some types they only have to take one bite, so you put the block out for that short period of time, in the attic or under the house, which ever of the 2 you see the rodent evidence. On the rare occasion I have had to do this, I prefer the blocks not the pellets, because they pellets they can carry in their mouth without biting it, so they will go bacl and forth carrying it to their nest, some other uncontrolled location. SO, with a bait block, you put a wire thru the hole in the middle and tie it to something solid, and then they have to bit it to take any. And if one bites kill them, you dont have over use or over distribution of poison. YOu then check the bait block after a couple days, and if it shows signs of being gnawed on, you untie it and remove it, put what is left back into its packaging and away in a safe place. Never just leave it out "incase" others get into thehouse. This is how it is missused,people buy it and leave it out always, even outside ! I have met people at thehardware store like this ! But, ifnothing else works, you must as you cannot have them in the walls, they chew in electric wires and you can have house fires and it is bad to breath, it affects indoor air quality. But, most of the time, you should be able to kill them. Look at you tube videos about how to properly set snap traps and then go to the other powered traps
