Carpenter Bee Trap, Large Version

 by unclesam
Featured
These traps catch carpenter bees that want to attack my wooden house. The first photo shows the assembled trap, the second shows the trap in place with a bee in the capture jar. To see my related Instructables, click on my username wherever you see it on this page, or enter unclesam in the home page search box. On the new page, click "view all __ instructables." On the next new page, click "NEXT" repeatedly to page and scroll through them all.

My design is based on that of kentdvm http://www.instructables.com/id/Making-Carpenter-Bee-Traps/, see his project for construction tips. His trap is hung like a lantern and has an overhanging roof. Mine needed to be attached directly to the wooden overhang of my house, high above the ground, so it did not need its own roof, but it did need to be emptied by someone standing on the ground far below. I did not have weathered wood for making the trap, so I used ordinary lumber, on the theory that the bee is lured not by the trap's wood so much as by the pre-made holes. My design for a smaller trap will appear as its own Instructable as soon as it proves it will catch bees.

Any carpenter bee trap will be more effective if the bee-made holes in the protected structure are plugged. I use a color-matching outdoor caulk.

Step 1: Plastic Parts From the Grocery Store

bottle jar.JPG
The capture jar is a Ziploc Medium Round Twist 'n Loc plastic container, marked 32 fl oz, 946 ml, and its lid. The jar is unique in that it has some flats molded into its sides, which allows it to be unscrewed from below by a tool made from a second identical jar.
The clear plastic funnel is cut from a Dasani brand drinking water bottle, chosen because it has a unique pinched waist ("rest mark")  that secures the funnel in the trap.

Bearing in mind that the majority of bee species are threatened to some extent, what happens to the bees after they are trapped?
unclesam (author) in reply to KitemanJul 24, 2012. 10:36 AM
Kiteman, carpenter bees are pollinators, so your concern is valid. This kind of trap is selective in that it is not attractive to other kinds of bees, and unlike poisons, the trap will not harm any other insects. It also kills only those carpenter bees that intend to attack the protected wooden structure. I have seen no reports that carpenter bee populations are dwindling overall, and I wish no harm to those that choose not to attack my house.

You might as well be asking what happens to termites after they're trapped. If you've ever had carpenter bees chewing on your house, this simply is Not A Question.

To answer: what mostly happens is that they dehydrate/starve to death. And this is not a bad thing.

It is good and just! Who needs a support beam full of big holes, just waiting to break and cave in ? Same for all critters that are dangerous, poisonous, contageous, etc. etc...

Nice idea! if you don't have the tools try this. If you want the carpenter bees (natures cordless drill) gone. Just put a couple of moth balls where they stay, they will move. My problem was solved the next day. Doodado

Do you think it would work on carpenter ants?
doo da do in reply to CymruJul 23, 2012. 6:38 PM
I have not tried it on ants. We have lots of the little ants, get 16 oz spray bottle about 12oz water, a few drops of liquid detergent, approx 3oz cider vinagar shak and spray those muggs die in 15 seconds. Only ants I have tried it on. Found this on inst, let me know if it works. Doodado

Sorry to stray away from a great instructable, but I am curious about the "Ant Spray" Is that concoction safe around pets? Got some of those little ants running around and I don't want to put out terro with cats that seem to know how to fit every crack that their heads can get into.
jbailey7 in reply to OutlawKtuluJul 27, 2012. 10:26 AM
For those with Ant problems here's another solution we've used, sprinkle grits around the mound/hole where you see them. They will eat them, bring them into the nest to share and spread them to others for you. Once they drink water the grits expand and the problem begins to self destruct. Very pet friendly and no chemicals going into the ground.
Apologies for being off topic for this instructable.
doo da do in reply to OutlawKtuluJul 26, 2012. 3:14 PM
The spray is warer, cider vinagar, and dish soap. I usually spay on counter, but I don't think it would harm pets. The terro should be put where the ants find it , maybe a corner, that is surrounded close so the cats can't be reached. I have 4 dogs. The Terro works it is taken to the nest and fed to the queen.

It should be safe around cats. It's the soap that really makes it work. Soap in the water makes the water "sticky" so it doesn't drain off the ants and then the cider vinegar acts like a poison.

Your cats should take a sniff of the liquid, sneeze, then walk away from it.

Thanks!

We now resume normal comments about the Instructable!

Could I modify this to work on the wasps that keep wondering into my yard to die?
unclesam (author) in reply to TheHobbit81Jul 27, 2012. 10:20 AM
TheHobbit81, this trap design might work on wasps, but you would need to put a wasp lure in its capture jar. I do not know what material would work as a wasp lure, though it probably has been figured out, because I believe there are wasp traps sold at home/garden centers that must include some kind of lure. Maybe some research would reveal it, maybe it's a pheremone (sex lure). If what is bothering you is yellow jackets, a good lure is a few tablespoons of a sugar-sweetened (not artifically-sweetened) beverage, especially grape soda.

The trap stays under a roof, where it's dry, right? Wondering why such a stress on waterproof construction.
unclesam (author) in reply to danzo321Jul 27, 2012. 10:06 AM
danzo321, the trap is not under a roof, as I use it, it is under an outdoor overhang of a roof. Rain, sleet and snow can be blown onto the trap, and humidity can also affect its materials over a long period of time. I intend to keep the traps in place, rather than take them down over fall/winter, because they are mounted where they are hard to get to (high up), so water-resistant construction should make them last longer. That's the only reason for the water-resistant construction.

Or, just put up a hotel for them. They are just a bunch of little cardboard tubes. Build a rectangular frame for them in a few minutes out of scrapwood. They'll prefer pre-made tubes over your shed. Or, give them both. Carrot for those that use the hotel, the stick for those that attack the shed.

Very nice design. Good use of materials. I like the rational for the Dansini(sp?) bottle - elegant attachment! And Pocket Screws - very neat!
auntwrennyz says: Jul 26, 2012. 7:18 AM
We use something similar for wasps but the jar has water in the bottom. Would water in the bottom of this keep the bees from entering it and getting trapped? Just curious...
My Key in reply to auntwrennyzJul 26, 2012. 9:05 AM
No, it would not. Carpenter bees aren't attracted to these traps for food. They are attracted to the wood so they have a place to put and protect their babies. The lure is the wood and the premade holes in a dry environment. Putting any type of attactant in the trap will give you poor results.

Related to Carpenter bees: If you are replacing the wooden boards that have been destroyed by these critters, go get yourself some curb-shopped white or light colored exterior grade paint and give your new lumber at least two coats on all surfaces (plus at least one finish coat in your color of choice) before installing.

Caulk any cracks that aren't bee tight too.

If you seal a bee within a freshly painted board, they will chew their way out, but given a choice they would prefer to chew on your neighbor's wood instead.

Great trap! I really like the improvements in look and function over the hanging traps. They are much less noticeable. Thanks for sharing!
