Carpenter Bee In St. Louis

With the warming temperatures in St. Louis and the increase in insect activity, we have been talking a lot about wood destroying pests such as carpenter ants and termites. But there is actually another wood destroying pest that we wanted to draw your attention to... Carpenter bees can also be a threat to the wood structures of your home, especially untreated wood.

Carpenter bees, which are thought to look a lot like bumble bees, are actually very different in their behaviors than many other bees or stinging insects. They carve galleries into wood in order to create cells for their eggs and larvae rather than forming colonies or hives. Perhaps not as destructive as carpenter ants or termites, carpenter bees are still of concern to the wood structures inside your home. Even outside of the home, carpenter bees are a threat because other animals, like woodpeckers for example, can end up causing more damage to wood trying to eat the larvae out of the galleries.

Signs of carpenter bees include:

  • holes that are about 1/2 inch in diameter where they enter wood structures

  • sawdust piles from their carving habits

  • large, slow moving bees buzzing around the wood structure

The females do contain a stinger but it is rarely used unless she feels threatened. Male carpenter bees, on the other hand, appear much more aggressive but do not have stinging capabilities. They are more of the protector and are often found buzzing around outside of the entry hole to the carpenter bee nest. Because carpenter bees can damage wood in your home or outside on decks, our St. Louis pest control professionals advise that you follow these tips to help prevent a carpenter bee infestation:

Make sure that wood structures around the home are painted or stained. Carpenter bees rarely go for treated wood sources because they find it hard to cling to shiny coats of paint.

Patch holes in wood because these may be from old carpenter bee nests. They are known for abandoning nests but they are also known for expanding older nests so it is best to fill in the holes and make sure they cannot get back inside.
