I've been waiting for the yearly onslaught of JBs. They've been drifting in at anywhere between 1 and 5 per day but some days have no "visitors". Unusual based on the last two years. I know they prefer the warmer temps with not much rain. Has anyone else experienced an unusual showing? Are they waiting to attack all at once?

Maybe the combination of rain and cool temps has forced them to give up? Maybe they're not prone to fly as far when the weather is miserable? I wasn't sure if the situation was specific to just my garden or if any other folks have had the same experience. Most of my JBs fly in from other properties. It's been several years since I put down milky spore on the lawn (and I've been reading how the JBs are becoming immune to it) and I hand-catch all the JB's in my small sunny garden rather than use sprays or systemics. Just curious.

I thought so too at first but we had several terribly hot days after *weeks* of rain and the JBs appeared - ate my roses for a week in July and have tapered back now to just a few. All in all not a bad year for them - most of my trees went unscathed. I'm in 5a NW IL.

I did see an increase in the JBs yesterday but no more than 10. Most days 2 or 3. I'm at home during the day so I can patrol my small sunny garden. Maybe I'm just catching them in time before they can send out too many signals. I've caught maybe 30 to 40 when I would normally be well over 100 in the season.

JBs still drifting in. Gosh, I hate those things. Getting my second flush of roses (which in other years is usually a non-event) so at least I know where to look for them. Tried zonal geraniums in pots this year but didn't have a single customer. I will say that this year's batch of JBs are behaving a little differently. Slower, more sluggish, not buzzing around as much. Maybe because there are fewer of them, there are as many pheromones floating around to drive them crazy?

Howdy, Shadegardener, from a little closer to the lake. I have seen very very few JBs compared to other years. I think I've only seen 5 total. Like you, I just grab them and kill them. I never got around to using milky spore but the many moles in the yard do their best to kill the grubs.

They usually flock to my Kiss-me-over-TGG which reseeded little this year and is only now thinking about blooming, so maybe that's why I have so few? But I have a rose of sharon blooming and I think they love those.

Hey, Seedrat -
Yesterday was a big day for JBs - I think I caught 8. I thought they'd start winding down by now but here they got a later start. Still not as many as the past couple of years and they don't seem as vigorous. Not a lot of flying and easily caught. Wouldn't you know that I'm getting a good second flush of roses - usually don't get that many most years - and that's where the JBs are now targeting.
I did hear about a new BT product that works on Japanese beetles - I think its Btk (nicknamed Beetlejuice). Haven't checked into it yet but that might be the next step since some studies have shown that milky spore doesn't work as well anymore on JB larva (read it here on ATP).

Interesting--I haven't seen any for a week. I have just 2 roses and only one has any flowers right now, maybe I just don't have enough to keep them in my garden right now and they're flying off to eat and lay eggs somewhere else.

The JB have been pretty bad this year in NW Missouri - worse than the past 4 years, but not horrific. Wnen I lived in New England they were HORRIBLE. Had to rely on traps or you could forget Roses.

Here this year they did a lot of damage to Hibiscus and Roses. I enjoy squishing them.

Far worse this year has been grass hoppers - zillions of the little buggers and they do a lot of damage. Last year they practically trashed a Serviceberry over night.

Without much experience with grasshoppers, I always envision them as out on the plains - tv references. I might get a few at the end of the summer when we have drier weather but nothing to act upon.
I think the JBs are finally done for the year. I did catch a few over the weekend but none since. Of course, it's been much cooler this week with a couple of windy days which seems to inhibit they're flying to the buffet. I think I can officially retire my stinky coffee can of drowned JBs for the season.

Here in south central WI - I never saw them on my roses, but something has decimated even the Wm Baffin and rugosa. However the other day was at friends' house and they literally had clumps of them on their roses.
I have one plant that seems to attract them and it is a gaurs, perhaps Siskiyou Pink. Again clumps/pairs of them all over. OTOH, it isn't all bad, I know where to look and then I flick them into a container of water mixed with some cooking oil. Drowned!

My JBs have been gone for a couple of weeks. The season seemed to start late and end late this year. I'd say the population was only about 25 to 30% of what it's been the two previous years. Good for me. No big plagues of them even though I had a good second flush of roses which I normally don't get. Finding them when they're hiding under the leaves when it's hot is my biggest challenge but not enough damage to complain about.

Thought I'd post my solution to Japanese Beetles. It works but you'll have to look at a white bucket by your plants. But that's a lot nicer than chewed up plants! They love my clematis and hibiscus blooms... Grumbling

I do try to knock the beetles into a container of soapy water where I can reach them. If I can't reach them, Azamax to the rescue! Once Azamax is sprayed, will it affect the beetles if they try to eat the sprayed surface?

Memeroies of the year they ate my Red Leaf Maple to the Bark and killed it , an 8 ft salad ,, Thumbs down

Nothing like that since the following year , I could shake a plum tree and it was like a swarm of beetle bees would fly everywhere ,, soundied like bullets bouncing off the garage siding , Blinking

Traps , smash , as many as I can catch , Glare
In the Butterfly garden if a plant is not chewed up I feel like a failure

Yes. Azamax does not kill insects by direct spraying on the insects. It kills by making the plant taste bad, stops insects from eating, by preventing the insects from maturing, laying eggs, etc.

Is it safe to use on raspberry bushes? We had an awful time last year picking them off the raspberries (and roses). They even were after the daylilies a little.

Thanks, Gene, for clarifying for me.
Sue - DD's raspberries in MI get covered with JBs.
