Carpenter bee gets its name from the damage it does to wood. They will attack areas of the home that may include the roof trim, siding, exterior columns, steps, decks, porch beams, outdoor furniture and fences. Entry holes will be approximately one half inch round with a sawdust-like debris below the area being tunneled.

What to do if stung;
Go quickly to a safe area
Remove stinger as soon as possible
Don't squeeze stinger; pressure will release more venom
Scrape stinger out with fingernail, knife blade or credit card
Wash sting area with soap and water like any other wound
Apply ice pack for a few minutes to relieve pain and swelling
Seek medical attention if breathing is troubled, if stung numerous times or if allergic to bee stings.
