How To Make A Carpenter Bee Trap – (DIY Video Included)

Every Spring and Early Summer, carpenter bees decide that my house is the hottest vacation destination, and they destroy my patio by drilling holes into the wood. With twenty years of pest control experience, I’ve noticed that the most effective way to get rid of carpenter bees is by using carpenter bee traps.

I’ve seen carpenter bee traps for sale which are great, but I didn’t want to spend a bunch of money, so I decided to make my own. It might not be the best-looking trap on the market, but in this guide, you’ll learn how to make a carpenter bee trap that is cheap and very effective!

Because a lot of people are visual learners, we decided to make a video on how to make a homemade carpenter bee trap:

Materials Needed To Make A Homemade DIY Carpenter Bee Trap:

  • 4×4 cut to about 5-7 inches in length.
  • a 3/4 spade drill bit or equivalent tool to drill holes for the main chamber.
  • a 1/2 spade drill bit or equivalent tool to drill holes for the side chambers.
  • a mason jar or jam jar to catch the carpenter bees.
  • two 1/2 inch wood screws.
  • optional: a hook or staple to hang your traps on.

How To Make Your Carpenter Bee Trap:

This is a relatively simple but effective carpenter bee trap, and it only involves a few steps. The overall idea is that we’re going to be cutting a main chamber, and then holes on each side which connect to the main chamber, and then attach a mason jar to the bottom. This allows carpenter bees to enter into the sides, and then they’ll make their way through the main chamber and into the mason jar, where they’re then unable to get out.

Step 1: Drilling The Main Chamber Hole:

The first step is to cut the main chamber hole, I used a 3/4″ spade bit, and drilled down into the 4×4 block about 2.5-3 inches. You want to drill this hole so it ends up around halfway down into the 4×4 block.

Step 2: Drill The Side Chamber Holes:

Now you’ll need to drill the side chamber holes, which will start around halfway up the 4×4 block and will be angled 45 degrees down towards the main chamber connecting the side holes and the main chamber.

I personally switched to a 1/2″ spade bit for this portion for better control of the drill, but you can keep the 3/4″ spade drill bit on if you’d like.

Drill this on each side face of the 4×4 block, so you’ll end up with 4 side holes which all will connect to the main chamber hole drilled in Step 1.

Step 3: Drill Mason Jar Lid To Bottom of Trap:

Now you’ll screw the mason jar lid to the bottom of the trap, this is the side where we originally drilled the main chamber hole in Step 1.

Optional Step 4: Attach Hook To Top Of Trap:

Depending on how you plan on hanging or positioning your carpenter bee trap, it might be easiest to simply attach a hook onto the top of the carpenter bee trap which will allow you to hang the trap along the eaves of your home and around your porch.

Final Product:

You’re officially done! You now have a fully functioning carpenter bee trap that will catch carpenter bees in the mason jar before they decide to drill into your home! I make one or two of these traps every year, and by the end of Spring, it’ll have quite a few carpenter bees in them!

I hope this project was helpful and helps to protect your home this year!

Still Dealing With Carpenter Bees?

If you’re still dealing with carpenter bees after setting up your traps, then here are a few additional suggestions I’ll add! I’d try creating a carpenter bee bait for your trap that will help lure bees into the trap rather than to your home!
