  3. Find all entrances to the nest. The entrance to the tunnel system is easily recognizable – a long yellow stain is an unmistakable sign. In some cases, carpenter bees’ nests may have up to 5-10 entrances.
  4. Take a WB40 spray gun and put a spray stick as deep as you can into the hole. Spay the lubricant in small doses. Repeat for each entrance.

Pesticide is what kills carpenter bees on contact and is a 100% solution for these cases. But remember that such kinds of chemicals are extremely toxic, so don’t forget about safety measures.
  7. After all bees are killed you have to make sure that carpenter bees won’t settle down in the same place again. Seal all the nest entrances with plaster or polyurethane foam.
