Carpenter Bee Wars

[ovrszd]

I enjoy watching the confused bees hovering around my vinyl.
I'm easily entertained.
I have an old stump pushed up at the property line that is a home for all the wayward carpenter bees that need a place to nest.
Drilled a bunch of holes in it to attract them to it. They seem pleased.....

Are they beneficial in some manner?

Are they beneficial in some manner?

We captured them as kids in mason jars as they were feeding (?) on azalea blossoms. So pollinators?

Bifenthrin this year

in the last day or two - I've taken to combining them. From my perspective this is war and in war there are no rules.

Hardie, which solves the problem.

Yah Concrete would tend to slow them

My son sent this to me...I plan to try it...

three years. Did they leave a paper bag out for three years?

I've been fighting carpenter bees for over 30 years. They're burrowing into the beams and eves of the house & deck. Chemical sprays work fairly well but I'm at the age where climbing a ladder to apply the spray is getting difficult. I tried different traps over the years but none worked very well. Lately, my wife and I have been making sport out of swatting them from the deck with a badminton racket.

A couple of weeks ago, I asked a buddy who works part time as an exterminator. Before spending big $$ on a professional, he suggested I try these traps:

Apparently, they don't work in every case but for us, they seem to be quite effective. My exterminator buddy said to put them in the sun as close to the problem areas as possible. We hung one on each end of our deck and the results are encouraging.

After just 4 days, there are at least 25 bees in the first trap:

and 10 or so in the second:

We see far fewer flying around than a week ago. We'll see what happens by the end of the season.

I built my own traps like this out of 4x4 post lumber. 1 hole on each side that leads upward to a vertical hole going out the bottom of the block into the mason jar. I have 8 of them on my log garage, shed and house. Each one has captured and killed 20-25 carpenter bees so far this Spring. Made a noticeable dent in the carpenter bee population.

That is what I have, I use a 2 liter soda bottle instead of a jar. Working good.

I have 3 homemade traps using the 4x4 block and bottle method. They work fine. But they do nothing to protect the buildings. They only capture the bee stupid enough to go inside. The other dozen flying around are not affected at all. I'm looking for a deterrent.
