When carpenter bees drill a hole into the wood, they will drill about one-half inch wide, and the hole is 1-3 inches deep. When they drill into the wood, they can do damage to your home. The bees do not eat wood but drill into it to construct their nests. It will take the bee a few days to chew one hole to start building the nest. These bees do not sting unless you disturb their nest or provoke them. 

Carpenter bees are located in the Eastern and Western United States. They have large and small carpenter bees. Again, when wood is soft, they will build nests in trees, decks, picnic tables, windowsills, old wooden barns, and sheds. The eggs are laid in the tunnels that they build and eventually hatch by chewing their way out. If you are a gardener and want to attract bees, there are preventative ways to keep carpenter bees from building a nest. 

What Are Carpenter Bees Attracted To?

Carpenter bees are pollinators so they are attracted to many flat and open-faced flowers such as daylilies, zinnias, salvia, bee balm, asters, lavender, and oregano.

Some types of passion flowers are one of the main types of bees that pollinate them. They feed on nectar and transport pollen to other flowers. They pollinate these plants and allow them to produce more seeds so these are what attract carpenter bees and might be bringing them around your home and garden.

Preventing Carpenter Bees

Some plants repel carpenter bees like basil due to its fragrance, and geraniums because they contain little or no pollen. Woodworm contains a substance toxic to insects called absinthe.

Thyme is another herb that repels carpenter bees due to the scent. Citronella grass has a citrus scent that carpenter bees do not like. When it is planted near gardens it keeps them away.   Eucalyptus trees, when planted in the yard, grow, and have a strong scent that carpenter bees dislike. These are some plants to consider planting to keep these bees at bay. 

Carpenter bees love flowers, so if you have a flower garden it will attract them to your home or property. Untreated wood attracts them to build a nest near your home or in the wood. Treating the wood on your deck, fence, or home may deter them from building a nest. Using varnish, staining, or painting the wood on the exterior of your home, deck, buildings, and fences often works.  In some cases, it will not, and an infestation may occur. 

Watch out for wood piles, cover them, or store wood inside a tool shed or indoors to keep the bees away.  Vinyl or aluminum siding is a better choice for siding as bees are attracted to wood. Some gardeners spray citrus oil or almond oil on the wood surface in early spring to keep the bees away. You can buy citrus oil in many stores and making your own is labor intensive. The smell repeals them and drives them to go elsewhere.  Similar reactions are from sprays such as vinegar or even WD-40.

Some gardeners install pre-made bee houses that they sell in garden shops and hang them from a tree in the backyard far away from the house. It is designed for the bees to create a nest. If you do this, make sure the holes are large enough for the bees to get into. You should have some knowledge about handling bees before attempting to use bee houses. Carpenter bees are attracted to using a bee house due to the nature of their species.

Pest control companies may dust the nests in the evening to make sure all the bees are in the nest. Sometimes they will properly seal the opening made by the carpenter bees if this will help prevent further infestations. They have special equipment that can spray or dust a long distance because carpenter bees often drill long tunnels in the wood where they make nests. 

Some nests are fifteen feet or higher and you need special tools that can reach the area. To keep the bees from building nests the following year, pest control companies spray your home yearly.  They have the products to keep them from rebuilding their nests.
