Green Beans VS Japanese Beetles, Beetles Win!

Last year green beans were out of the question due to a plague of Japanese beetles. This year started out, pretty much the same. I am determined to get a good crop of green beans. To accomplish this feat, I have to get rid of the dreaded Japanese beetles by mid July.

Just look at the damage they do!!

I decided to try Japanese beetle traps.  (If you need traps, I can recommend these over on Amazon.com: Japanese Beetle Trap.) The trap consists of two plastic rectangles (holes punched and slotted), pheromone lure, plastic bags and a twist tie. I have made a modification to the collection bag by cutting off the bottom of the bag and suspending the trap in a 5 gallon bucket filled with one to two gallons of soapy water.

The beetles are lured to the pheromone, fall into the bag and drop to the soapy water.

A large tomato cage was used to suspend the trap above the soapy water. I use dish soap vs dish detergent. The soap bio-degrades and is friendly to the environment.

If I used just the bags, I would easily go through three to four bags per day. What a waste! You can use the same bag over and over again. The bucket is emptied once a day. The soapy water kills the beetles within minutes. I toss the dead beetles out in an out of the way place to break down and compost on their own.

The two traps have easily killed thousands of Japanese beetles. YES!!!!!!! I am already seeing a difference. There seems to be fewer beetles.
