This year mice seem to be seeking indoor living spaces earlier than usual! It may be related to the cool start to the season. This information about controlling mice was submitted by biologist Roberta Roberta Olenick.

Please do not use poison to get rid of mice. I know they can be a problem if they come inside your house, but poison is not an appropriate way to address the problem. A poisoned mouse, even if still alive, can pass the poison on to innocent victims including pets and wildlife.
Even if you put the poison only inside your house, that does not solve the problem of non-target species getting poisoned. A poisoned mouse can easily leave your house before it dies and get eaten by your neighbour’s cat, an owl...
Glue traps are inhumane, causing slow and agonizing death, and may catch non-target species.
The good news is there are far safer and more effective ways to control rodents besides poisons and sticky glue traps. Snap-traps usually kill mice quickly without harming non-target species. Even more humane is a live trap to catch the mice and then relocating them away from your home. Here is a link to how to make your own live trap using common household items.
You could also try cayenne pepper to keep mice away. Also, steel wool to block gaps where they are entering your house works extremely well.
Here are a couple of links about the serious negative impacts of rodent poisons on owls.
