The extra mice in your house this winter may not entirely be the result of you not cleaning your kitchen thoroughly, the AP reports. As climate change makes winters warmer, white-footed mouse populations are rising as more are able to survive the winter. All this combines to increase populations and allow them to spread further north. “Right now, I would say 30% to 40% of our calls involve mice, which is pretty surprising given the time of year,” Allie Dickman, of AAA Pest Control in Noblesville, Indiana, told the AP. “They’re just adapting and expanding more … and there’s more of them.” (AP)
