Anything you do is better then nothing!
I say, first bring the rodent population down.
Every fall I buy some Rat & Mice poison from Canadian Tire, the ones what come in pellets in little plastic bags, put one or two bags in a gallon plastic planter pots, put another on top and put it under wherever you find it suited to check, I put mine under spruce trees, under shed, wood piles etc.

I find this method is save, in the sense that only mice can go in and out from the pots drain holes.
This I do on the acreage, in town, I usually keep some around in the shed, mice know where the goodies are.
Second, spraying or paint fruit trees, mainly on trunk, with half water and latex paint, a little bit of Thirame powder added. This I have done only outside of town.

Thanks, Konrad. You steered me onto a direction that I hadn't really thought about. Canadian Tire - here I come. I'll have to be a bit careful because of my own cat, but maybe I can invite the neighbour's annoying felines over for a visit. No, I wouldn't do that. But, I can see where setting up a few bait stations would certainly help save my trees.

Today I went out and re - filled some of the empty pots.
Actually, this stuff is called Rat & Mouse Pellets, a product from CIL and it should kill with a single feeding.

I put the bags in the pot without opening it, mice nibble it nicely open for the rewards..gee I'm bad!
The first couple of re - fills are usually within a 2 to 3 weeks period, then it slows down to almost 0 fills for the rest of the winter,....in my neck of the woods.

One fall I bought juice fruit gum for about $20,
as one lady told me that it works, about two month
later I think the population went up because they wanted
more and more! ....Then it was back to poison.
I still don't like to use poison, ..well I just bought about a dozen of traps to ease on the poison.
