kentdvm recently posted an Instructable for a carpenter bee trap, http://www.instructables.com/id/Making-Carpenter-Bee-Traps/
which uses two bottle caps connected together as part of the assembly. He used tape to connect the bottle caps, and here I offer another method that uses 1/2-inch metal grommets from a tarp repair kit. Photo is of one of my own variations of the trap, designed to fit under a small roof overhang. A separate Instructable for this trap will be posted soon.

Step 1: Tarp Repair Kit

I happened to have a kit for replacing metal grommets in tarps, bought years ago from some mail order tool supply company. It contains 1/2-inch metal grommets and metal capture rings, a tool for punching a hole through the tarp, and two tools for easily and neatly setting the grommets.
<p>thanks to this post and others like it. our native bee species are disappearing from the planet at an alarming rate. i guess u dont love honey at all.</p>
<p>Carpenter bees don't make honey. You could put one of these traps every 50 feet all over North America and you wouldn't kill off those carpenter bees. The main reason native bees are disappearing is because of too-neat suburbs. Carpenter bees need dead wood to live in, and most suburbanites remove that as soon as possible because it's not pretty. I have a stand of dying walnut trees just across my property line and it produces so many carpenter bees that my bee traps consistently get between 20 and 50 bees a piece in the spring and fall, and I am still drowning in live ones. These traps do kill carpenter bees. They are not effective enough to eradicate carpenter bees.<br>If you want a bottle of dead bees though, these rock!</p>
.I took an old discarded La Crosse raquet (spring trash day) that I found some on the side of the road. Lashed it to a long birch sapling with two auto hose clamps. It is great fun to swat those nasty hole boring bees with. When I hit them I hear a &quot;pong&quot; sound. Then I run over to them and they are usually D.O.A. ! Very satisfying!
Transquesta dn unclesam: you both need to do more research on Carpenter Bees. They do not sting. They do 'seem aggressive' but they are inquisitive and pesky as a toddler with 'why is this and what is this'. They catch their reflection in your eye and they want a good look at themselves! I've noticed they like it when I work on something that takes oil (tiller, lawnmower). The flapping of their wings do make an unsettling noise buzzing about your head but I've yet to have one attack me. Quick detection is, A bumble bee (which will sting) doesn't have the big black bumm (rearend). <br> <br>Carpenter Bees cause far less damage than Carpenter ants or termites. <br> <br> <br>So once your bee is in the bottle...what then?
The bees may not cause too much damage but that 18&quot; cock-headed woodpecker will when he rips your fascia apart to get to the larva. Incredible bird but I have only seen once. I'm not willing to grow carpenter bees just to see one though! :^) <br>I do need to make about 3 of these traps.
Actually, I was stung once when I mowed too close to an old building, so I Googled and found out that the females will sting. The males just love to dart at us, scaring the bejez out of us. Thanks for post, since know I know a little more about these pesky lil beasts.
If you do not have the time or the tools, place a couple moth balls in the general area and they will leave the area. Tried it and they were gone the next day. Seen it on instructables. Doodado <br>
I like the mothball idea. Quick and cheap. Used them once to get squirrels out of a chimney.
Love it! Great solution for connecting the caps. Much more permanent than my tape. Thanks! kb
What baits the bee (typically the female WITH a stinger) out of the hole into the trap?
Transquesta, the female bee is not expected to be lured out of her hole by the trap, hopefully the trap will provide an attractive alternative to female bees that are just ready to set up housekeeping. It would help the trap to work if all the bee-made holes in the infested structure are plugged. An internet search will turn up a lot of useful information about the life cycle of the bees and various strategies for reducing their numbers. The Instructable is the first effective DIY trap I have seen, so I thought it would be worth adding to the arsenal.<br>Unclesam
this trick could come in handy for other applications as well, I'm going to remember it. Thank you for sharing
