Carpenter Bees

First, the Carpenter Bee facts: These types of bees are also known as wood bees or drilling bees.

A few facts:

  • Male Carpenter bees do not sting but female bees do if agitated
  • Perfectly round bored holes usually found on the underside of the wood lead to nests for their eggs
  • Up to 20 carpenter bees return to the hole and its nest each night
  • Bee stomachs are a shiny black (unlike bumblebees with yellow hairs)
  • Specs of sawdust blowing in your eyes or small piles on your deck are the first evidence that Carpenter Bees are chewing on your wood carpenter bees sawdust from drilling holes
  • Yellowish excrement nearby on a wall is also an indicator of Carpenter Bees
  • Carpenter Bees are most active in the spring as they look for a mate and drill a hole to make their nest

Organic ways to stop Carpenter Bee boring and drilling essentially mean block the hole with something, or you can bat them down with a Spiderman bat as she does in the picture…just stand far away when you bat the bees or use a salt gun.

  • Block the hole with duct tape…roll it and shove it in the hole
  • Shove a stick or wooden plug into the hole
  • Fill the hole with caulk or wood putty or duck tape

Pesticides that you can buy locally also are effective but often are messy because the hole is usually on the underside of the wood area and so some of the residue easily drips out and on the surface below…what a mess most time.

You can sometimes stop Carpenter Bee hole boring by using treated and/or harder lumber or painting the wood or (of course) use brick or stone to redo the outside of your house (duh).
