Picture of Carpenter Bee Trap, Small Version
Bees.JPG

This easy trap will help control carpenter bees that threaten your home without the need for baits or poisons, and it will not attract or harm any other kind of bee or insect. The trap will not lure carpenter bees in from a great distance, but will trap those that are intent on damaging the protected structure. Wood-boring female carpenter bees enter the pre-made holes, then they become dessicated by the sun in the capture bottle. The first day this trap was installed, it caught the four bees shown in the photo.

Step 1: Components

Picture of Components

There is nothing special about the components and their dimensions. Feel free to substitute, though I would not use plywood for the sides of the box because its exposed glue might deter the bees.

Wood for box, solid, one inch thick, 4 inches wide, does not need to be weathered

Wood for box lid, I used a scrap of 1/4-inch thick marine plywood 4 and 3/8 inches square

4 drywall screws for attaching lid to box

wood glue for outdoor use, such as Titebond II, to assemble the wood box, or alternatively drywall screws

Rectangular plastic 500 ml Fiji bottled water bottle and its cap (WalMart). This is the only rectangular bottle I could find, and it is sturdier than most other water bottles.

Deer Park Aqua Pod 325 ml plastic bottled water bottle and its cap (grocery store).

Metal grommet for connecting the bottle caps together, sold as part of a kit for placing grommets in tarpaulins; alternatively, outdoor tape

There is a much easier and more ingenious design for a trap that uses a simple block of wood and can be seen at my frugal home . com . I'm going to the lumberyard today and have them cut me some wood.

That is easier and quicker. I like the trap here, but I need a half dozen _now_ and that block of wood/mason jar trap is perfect.

going to try and make one of these but going to put a board in the bottom with a hole just big enough to screw in a pop bottle.

If you really have to get rid of those bees , just take away their nesting habitat . they prefer wood that has begun to rot , makes for easier excavating . Carpenter and other solitary bees are just as useful in pollinating as are honeybees . Honeybee are being killed in huge numbers , by disease and pesticides . And as you will have trouble finding anyone who has been stung by a bumblebee , why kill the little critters ?

Because they are destroying my new decks that I have just built costing thousands of dollars.
I hope you are successful in killing them all dracnam! I also have them. People who haven't had the experience, have no idea of the destructive power of these "little critters"! It's like saying "Let's live with termites ... they won't eat much!" I'm going to try this! Did you try it and did you have any success?

That sounds like a genuine infestation . Do you have any piles of rotting wood , abandoned buildings ,any kind of wood laying unused on your property or neighboring land ? If you do ,you could keep emptying bee traps and there would be a fresh supply , forever . Your county insect or animal control office might be able to help , or the county's extension service could . That last is an office operated by your state's university agriculture program .
how about because they are loud, invasive and while adults understand the workings of bees small children still have the shriek and scream reaction! and those of us with deadly allergies to bees do have other things to think about than some annoying bugs. I dont care how endangered they are they aren't worth a human life.

This is awesome and when spring comes I'm going to give it a try. For the deluge of nay-sayers below... Carpenter Bees are enormously destructive, eating HUGE holes into the wood of your house. They are NOT bumblebees! One of the sexes stings. Seriously they will make Swiss cheese out of your home! If you haven't had the experience, please withhold the negative comments. It's like saying let's live with termites...they won't eat much! They are most certainly a pest that should not be tolerated for the good of your home and the neighbor's homes that they will infest at a later date! ~ written by someone who has them!

There is no wood or any kind of refuse just clean yards all around us but still we have these destructive carpenter bees.

Why not just give the bees somewhere else to live? Put up a tempting nest box instead.

Remember: one third of US food production, 130 crops, depend on bees that are already globally endangered.

Very ingenious trap! Much better than spraying some insecticides on the house. Reusing those plastic bottle was a good touch, too. I like the top-to-top caps, too, good thinking.
