Excavation takes a lot of energy so next year’s brood will simply reuse part of this year’s hole and extend it. Most commonly fascia boards but they will also attack railings wood fences or even window frames. The site of the yellow stains below the hole on the side of your home is an easy way to tell what is causing the sawdust pile below. They do not eat the wood but the site of a sawdust pile forming can be very unnerving for most home owners. If a woodpecker detects the larva in wood then they will destroy the outside of the wood looking for another larva that maybe nearby.
Do Carpenter Bees Sting
It is common to have a carpenter bee hover around your head in the spring, almost like a tiny helicopter. These are males protecting a territory. They will dart after other insects or people waving their arms to shoo them away. Females can sting but must have a lot of provocation. Males cannot sting.
Carpenter bees eat nectar and pollen from flowering plants. This process also fertilizes the flower to grow a seed called pollinating.
Carpenter Bee Life Cycle
When females bore into the wood and create chambers they are actually feeding chambers for the larva. Each chambers contains a carpenter bee larva in the back followed by a wax seal. Then a smaller chamber of food made up of pollen and regurgitated nectar so when the larva emerges it has a meal to start with. Then as the winter approaches the carpenter bees return to these chambers to hibernate.
Carpenter Bee Control
The pest management professional will inspect your home for nesting areas designated by the pollen and defecation stains on your home. These will be treated so that only the female and larva in this hole will be treated. Although there may be additional carpenter bees fling around your home intimidating you this behavior will stop shortly after the female are gone.
