We seem to have a lot of mice here in SoCal coastal! Worst, our environmental laws now prohibit most of the several effective mouse poisons due to "food chain" problems. Mice die of effective poisons and as eaten by larger varmints; which die. Some such, "protected species". I'd suppose we humans would need to add mice to our diet to get any regulatory relielf nowadays. In the meantime, those little furry creatures, continue to multiply and thrive! I've seen occasional neighbor tenting of their homes, presumably mice riddance, possibly 'other'.
A household cat might be helpful but we have several big - maybe cat eater - dogs. Lethal to the Feline species! Mice could bite our dogs in their butts, likely they'd not be disturbed!
Hope we don't get overrun!
But then, statistically nowadays, the mice more likely to get roasted, as California ever increasingly on fire! Good thing we don't have to worry about climate change too! All this just our overactive imaginations! frown

Best!
