We had only a very few JB's this year ~ they seem to be diminishing with each year that passes ~ thank goodness.  On the very first day I noticed them (about a month ago), I got out in the yard with my Tempo and treated every plant that they like:  crape myrtles, roses, plum trees, cannas, hibiscus.  They have hardly touched a one since.  I have heard  other folks say that they have a lot of them so maybe my early deterral caused them to go elsewhere. 

Oh, and I have noticed way more bees in the landscape this year too, and that's a good thing.  Just not in my hummingbird feeders, please.  (It helps to use the ones that do NOT have a yellow plastic flower around the feeding hole.)

Have any of you tried the HOMEMADE REPELLENT for Japanese Beetles?  I already have the makings of this mixture...DEAD SMUSHED BEETLES and DISH SOAP.  Put in small plastic container and put holes in the container so the odor of the dead bugs will warn the others of DEATH.  Place these containers near their desired plants.

This method seems too simple too work, but I will give it a try. Actually I have indirectly already have done this.  The soapy bucket I throw these NASTY CRITTERS in, is sittling on my deck by my cannas. Guess what??? They are feasting on my cannas while the bucket is sitting within 2' of the canna plant. But the beetles in the bucket are not SMUSHED. So I will SMUSH THEM and let them FERMINT and get NASTY SMELLING and then I will put a container by my green bean plants. I will also put a small margarine container of this NASTY MIXTURE at the base of my large container of cannas.Confused

When I was beetle picking last night I saw about 30 beetles on ONE hollyhock. Needless to say, I couldn't grad all of them and the plant now has LACE LOOKING LEAVES.Yell

Dave suggested I fill a small spray bottle with Bayer Bug Be Gone poisin and just spray them. I might be doing that.Surprised

I am still sticking to my tried-n-true Tempo diluted spray.  It works really well but here is the weird thing.  When I first noticed the JB's, I went all around the property and treated the plants that I know they like.  So far, they have left those alone.  But instead ~ they are now chewing on plants they never used to even give a second look.  Last night, I noticed they chewed up a lot of the ivy that grows on my porch every year (dang, so common but can't think of name ~ google images here I come).  They have never bothered that ivy before as it's basically a weed to some.

And it's been pretty easy to treat with Tempo as we have had no rain to wash it offFrown

 

Arghhhh ~ Virginia Creeper, common but I like it.  Makes my porch look so cozy.

Forget the SQUASHING BEETLES thing. Much easier to go with what my hubby suggested...Lark is armed with a hand held little pump sprayer.Cool My cannas, castor beans and hybiscus get all day patrol. I had several people touring today. That is when I put my PUMP PISTOL out of sight. LOL LOLLaugh

 

Who makes Tempo.  When I googled REPEL JAPANESE BEETLES, they all said "No repellant availble, only KILL ON CONTACT.  When I run out of BUG BE GONE, I will get the Tempo and give it a try.

 

I like the Virginia Creeper someplaces. The Fall color is awesome!

Here's the link.  It is made by Bayer.  Much as I hate to use it, I do use sparingly and with much care.  NOT to use on edibles, of course.  Although it is pricey, one bottle lasts me for years as it must be highly diluted. 

I get mine from the farm co-op.  You should have such a place somewhere in your area?

The 2014 Japanese Beetles have arrived. YellCry I have to get my soapy water bucket ready for tomorrows patrol.  This will now be part of my daily routine. Along with catching the cucumber beetles and the squash bugs.

It's so weird ~ I have little to no Japanese beetles this year.  Either that, or I have succeeded in adding plants that are not tasty to these nasty pests.  But I know that's not true ~ I have crape myrtles, roses, and other plants that they especially like.  Yet, I have only seen a couple this year.  Could it be that the moles ate all the grubs?  Or that the birds were supposed to finally "discover" that JBs are tasty?  Just wondering about this as my friends all have them and I don't.

this has been a wired year alright I don't have any. I don't have any squash bugs this year last year they destroyed all my pumpkins, and squash but not the cucumbers. I'm attributing it to all the very cold spring we had and all the rain. this week has been in the 70's dropping down to the 50's at night. the weeds are my thorn this year. sorry I couldn't shed some light on the beetles.

I have my first Japanese beetles this year.  I just read all the previous postings and now I'm worried I'll go out one morning and a "swarm" of them will have arrived.  So far I've only found 5 or 6.  I didn't know what they were so I put a photo of one on another garden blog.  Before I could post the photo here to ask Lark, I had gotten 3 replies telling me it was a Japanese beetle.  One of the commenters mentioned she used a white 5 gallon bucket with soapy water and the beetles were attracted to the white, flew in and drowned.  Sounds too simple but I thought I'd mention it.  If I get a "swarm" I might give it a try.

While it's nice and earth-friendly to pick the beetles and drop them in soapy water, there is NO WAY that will be effective here.  First of all, I have WAY too much landscaping to do such a thing ~ I would have to quit my day job.  Second, the beetles only seem to like certain plants (that's because I tend to avoid planting any more of what they do like ~ roses, crape myrtles, etc).  So I can target them on plants they chew on and then I do one dose of Tempo, and ............... done.  

When we first began to see them (about 10 years ago), they were MUCH worse.  Now it seems the birds have discovered them (reduce seed-feeding like Lark does if you think that helps).  The worst thing you can do is put out traps ~ that attracts them like crazy ~ buy one for your neighbors haha.
