Your message board is great. I read through the carpenter bee posts and some other sites and had a question.
It seems like there are two methods that I've found online for dealing with our carpenter bees.
Method 1 (from you):
1) Put a wet tissue in the holes to see if active
2) If active spray in WD40 at night and then do the tissue check again
3) If not active shove in a wire, then shove in cotton balls soaked with Xylene
4) If still inactive a few days later caulk the hole
If you don't kill all of the eggs with the wire and cotton balls, will the bees be able to hatch and drill a new exit hole? The other method says this is a risk and recommends:
1) Put dust deep in the hole with a duster.
2) Cork the entrance / exit hole. The cork is supposed to leave the path open, so that any bees that hatch from the eggs walk through the dust and die on their way to the corked exit and before they drill another hole.
Based on your posts, I know you recommend method one. Would you mind explaining why that is better than the dusting and corking? And, please letting me know if I made any mistakes in recapping your method.
Thanks so much.
