If you see large black or golden-brown bees flying in your garden or landscape, don't be alarmed! These insects are most likely carpenter bees, and although their large size and loud buzzing can be intimidating, they are mostly harmless. Males can't sting and females rarely do, and both are considered beneficial because they are pollinators.
However, sometimes carpenter bees bore into lumber or trees to make nests and may damage structural wood or leave unsightly holes and stains. Multiple bees may use a common entry hole, tunneling several feet into wood to create chambers for their offspring.
The best way to manage carpenter bees boring into wood is through prevention. Use hardwoods in structures where possible...
If you plan to camp this summer, remember to wait until you arrive at your destination before you purchase firewood. Why?
If you bring your own firewood to a campground, you could unknowingly spread invasive pests and diseases that can harm local trees. New infestations of tree-killing insects and diseases are often found in campgrounds and parks as a result of campers moving firewood.
Once you arrive at your destination, pests can emerge from the firewood and spread to the trees and forests where you camp. Invasive and hard-to-control pests kill several million native trees every year, causing environmental and economic problems.
