Carpenter Bees

[kantuckid]

Fill a garden sprayer with water and dishwashing liquid solution.  Spray directly into the holes and wait for the bee fall to the ground.  You know what to do after that.


Takes a couple years to get rid of all of them.

Yea, sure thing...

I went out and got 7 after making that post.  You can laugh but it works for me.

I was not trivializing your fix for bees. I was thinking towards how many we have and how high up they hangout around our house.
 It's well known that a soap mixture does kill insects, mostly aphids in my mind, but includes wood bees. The hose thing would not make my wife real happy as she just finished her spring cleaning not long ago and held off the windows until last thing as pollen comes down like heavy snow here. Given their aerial acrobatics you'd not be done around here in a few minutes to catch them not flying here and hit em with a hose and there might just be a months long job involved. My trap jars get full to the top and often.  
I will say that some of the web info suggesting various wood bee fixes is simply a waste of time. The one that easily comes to mind is to caulk the holes when they're gone. They don't leave a sign up to say they've quit using the holes and if you caulk one with a larvae inside it crawls out as does the bee placing the thing in there. 
I hate them.

Here in N.Y. we can't buy bee killing dust. The stuff we can get does nothing except color them white.                                        Here is a Question and a comment; can carpenter bees and their hatchlings be caulked in?   I know that in the air they will not bore in a 1" space. This knowledge comes from years of stickering white pine.  But once they do start boring they keep going so I guess I answered my question about the adult but what about the newly hatched?
