How it kills: Emerging from their winter slumber, bears are especially hungry now and aren't above searching your garden, garbage cans, compost pile, or birdfeeders for a meal. They'll even stroll right into the house if the smell of grub is strong and access is easy. Sure, they prefer to avoid contact with humans, but get in the way of one raiding your pantry, and he could charge at you and maul.
How to get it before it gets you: Never intentionally feed a bear: Monitor your bird feeders, never put meat scraps or fruit in your compost bin, and put garbage out in a bear-resistant container on pick-up day. Clean up after entertaining outdoors, especially the grill. If you spot a bear in your place, never approach it. Run the other way, and call animal control.
