Black bears typically den during the winter months and emerge in late March or early April. When they come out of their dens, natural food sources are scarce, which often leads bears to be attracted by the smell of human-related foods.
Additionally, June and July mark the breeding season for bears. During this time, male bears travel great distances in search of females, which increases their chances of encountering human dwellings.
Summer is also when yearling bears, now on their own, are trying to establish a suitable home range. In their travels, these young bears are often drawn to human-related food sources as well.
Moreover, as the weather warms up, outdoor activities such as camping, hiking, and picnicking increase. This leads to more human activity in areas where bears might be foraging, which can further elevate the chances of encounters.
