Homeowners often find themselves questioning the dietary habits of carpenter bees, specifically whether these robust insects consume honey. While their imposing size and loud buzzing evoke concern, the reality of their eating habits is more specialized than one might assume. Understanding what carpenter bees eat is the first step in dispelling myths and addressing the actual structural damage they can cause.
Carpenter Bee Feeding Habits
The primary food source for adult carpenter bees is nectar and pollen from flowers. They are vital pollinators, utilizing their long tongues to extract nectar deep from blossoms. Unlike honey bees, they do not store nectar as honey; instead, they convert it into energy for flight and daily activities. Their dietary focus is on sustaining themselves rather than hoarding sweet substances.
Do They Target Honey Stores?
No, carpenter bees generally do not eat honey. Their foraging behavior is geared towards fresh nectar and pollen rather than the processed stores of other bees. While they may investigate beehives, it is typically for an easy meal of resident bees or larvae, not for the honeycomb itself. They lack the biological imperative to collect and preserve honey for winter use.
Comparison to Honey Bees
It is helpful to contrast carpenter bees with their more famous relatives to understand their habits. Honey bees are social insects that live in colonies and actively produce honey as a food reserve for the colony. Carpenter bees are solitary creatures with no colony to feed, removing the primary reason to seek out honey stores.
The Real Threat: Wood Damage The misconception that carpenter bees eat honey often overshadows their true hazard: structural damage. Female carpenter bees bore perfectly circular holes into untreated wood to create nests. They do not consume the wood but excavate tunnels to lay their eggs, which can lead to significant property damage over time. This nesting behavior is the critical issue requiring management. They drill into decks, eaves, and fences to create galleries. Larvae develop within these tunnels, protected from predators. Woodpeckers may further damage the structure while trying to eat the larvae. Staining or painting wood is an effective preventative measure. Behavior Around Food Sources

While foraging, carpenter bees are attracted to flowering plants and trees. They are known to "rob" nectar by creating holes at the base of flowers, bypassing the pollination process. This behavior, while detrimental to the plant, does not involve accessing honey. Their focus remains on the immediate energy source provided by the flower.
Managing Carpenter Bees
Effective management involves deterrence rather than attraction control. Since they are not interested in honey, standard bee traps for honey bees are ineffective. The focus should be on sealing untreated wood surfaces and providing alternative nesting sites. If an infestation is suspected, consulting a pest control professional is the safest course of action to protect property.
