Japanese Beetle Trap





Introduction: Japanese Beetle Trap

How to make a reusable Japanese Beetle trap for $8 or so.

Step 1: Materials and Tools

You will need to get
- A bucket 3 gallon is what I have at hand but 5 gallon would work fine.(Free if you know where to look)
- A wire coat hanger (free with your dry cleaning)
- A "transmission fluid" type funnel. $2.50 at auto parts store.
- A Japanese Beetle Lure replacement $4.75 at hard ware store. The puck style works as well as the mesh pouch type so get what ever you can.
Tools You will need
- A multi tool
- A 1.5" hole saw

Step 2: Prepare the Funnel

Cut a few inches off the end of the funnel so the hole is at least 1" This will allow the beetles to slip down the funnel and into the bucket without clogging.
The one pictured has already been cut.

Step 3: Adding the Wire Hanger

- Using the awl from your multi tool make a small hole about an inch below the hole cast in the funnel. -Cut a length of about 10" from the wire hanger.
- Bend it so it is secured to the funnel using the 2 holes.
-Bend a hook into the end for your lure.

Step 4: Cut the Lid

-Using the 1.5" hole saw cut a hole in the lid.
you can use a smaller or larger hole saw if your funnel is a different size.
I off center the hole so I can place a brick on top of the trap when it gets windy.

Step 5: Bait the Trap

-put the lid on the bucket
-put the funnel in the hole
-open the bait lure and hang on hook
-watch the swarm approach
Oh you will also need a shovel to dig a hole to bury your catch(ashes to ashes and what not). Make sure they are dead before they go in the ground. They are beetles and have no problem digging out. A solution of soapy water will drown them quickly.

    Once I have trapped them in plain water, I am able to feed them to my chickens, they eat them like candy.

    I think I can improve on your trap to make it more effective! I will be building a trap similar to yours with one add on. I plan to seal the funnel to the buckets lid with some silicone. That way i can add some soapy water to the top of the lid to destroy the ones that can't seam to fly above the funnel to fall in.

    shouldn't the lure be in the bucket? How do they get in if the lure is outside. Any trap I ever made asks for the lure to be inside so they go after it.

    The lure needs to be above the trap so the scent can travel on the wind. They are very poor at landing and will crash into the lure and then fall into the trap.

    I buy the ones in the store and give them out to my nighbors,they love me for it,but what Im really doing is keeping them away from my yard,as the traps attract the things,so I havnt had near as many as when I started handing out the traps.Im really a hell of a nice guy though,and theyll figure it out one of these summers.

    I have a hand held dyson vac (battery powered) which has a long flat nozzle. Sucks them up by the dozen.. After the clear canister is full, I wrap it in a plastic bag and dump them in. Especially good for high difficult to reach leaves. No I don't work for Dyson. Work in Patents.

    Yes, that is a good idea. I did not trap last year because I did not want to deal with burying that many beetle bodies again. I have entertained the idea of setting the traps on other farms close by much like you giving out free traps to your neighbors...LOL

    So this works great without human intervention pushing them off the bait into the funnel? I know with the old out of fashion traps didn't allow landing, so they fell right into the bag.

    this is off the subject but has anyone used milky spore? if so how are the results. oh traps usually work if you put them in your neighbors yard.

    I have heard of it and we may be giving it a try this year but am weary of it's effect on "good" larva and caterpillars we want here.
