Darn - First Japanese Beetle Found Here Today
Comments (12)There are some organic products people use, but from what I've read, they repel and do not kill. If you do not kill them, they will burrow in your lawn, lay eggs, and multiply. One female can create 60 beetles per season. So you need to treat for grubs as well. Milky Spore may or may not work in my zone and is expensive. I'm going to try to get some Grub-X down but don't like killing earthworms. One product is Bye Bye Beetles, used by a rose grower in the southeast and recommended, an organic and repellant. See link. I may try it at some point, but didn't want to wait while it shipped and can't remember the cost. Saw my first one June 21 which was early, picked a few off and squished, started the soapy water thing. Then I cut back all my repeat blooming roses and am watching the rest of it. Haven't seen any since but that is not to say they will not find my echinacea, cherry trees, rose leaves, pussywillow or preference du jour. If too many come back, I will spray with Sevin. My primary reservation was bees, but if there are no flowers to attract bees, there's not much chance of harming them if I spray early am or late pm while they're out. My cat heaven knows what he gets his paws into roaming around, everyone treats their lawn, and I did for the first time this year in quite a few years, just got too awful, hated to do it, and nowhere near got it all, but much better. Some people cover their roses with nylon net and cut off the blooms which are the main attractant. Hated to sacrifice the blooms but won't use anything with imidacloprid because it kills bees, saw it myself, and has residual action. Also Sevin won't protect newly-opened buds. Pyrethrin knocks them dead (in time), think it's an organic, but doesn't last as long as Sevin. Then there are several home remedies involving concoctions I found recipes for on the web by googling, said to test on a small area first. Some of the ingredients are chili peppers, garlic, dishwashing liquid, lemon juice, vinegar, not all in the same recipe. A lot of rose people use Merit which you pour on the ground, must be done earlier and is a systemic, but if I'm not mistaken, it contains imidacloprid, bees again and other beneficial insects, does not discriminate. Good luck. My roses don't do a whole lot except two so let the perennials provide the color, didn't want to go through what I did last year again, in the hottest days, ruined that whole part of summer stewing about the dratted things. The only hopeful thing on the horizon is that some are reporting seeing some with eggs on their thoraxes? (white spots) and may or may not kill those. Those are laid by a parasitic wasp that destroys them when they hatch. But the gol darn things will mate first for sure as they do it sporadically before they die. I haven't seen any like that. There is also an ongoing experiment at the U of Michigan which involves innoculating adult beetles which will spread a killer virus from one to another, have been given to a few gardeners to test, but if it is safe, who knows how long before the rest of us get access to that? There are no known predators, some say ducks, maybe turkeys, chickens may or may not eat them but can't possibly get them all. No bird I know will eat them. Praying Mantises will, but it would take thousands to make a dent in bad outbreaks where they can number in the thousands and millions. That sums up what I've found so far. Hope it's helpful.

Comments (39)I'm absolutely inundated. They are everywhere, and my roses are in the middle of another flush at the moment. I've had JBs for the last 2 weeks, and they are so thick that they hit me in the head when I'm outside painting or gardening. My neighbors now think I'm the "crazy plant lady with Tourette's" after watching me whack them out of the plants and into the bucket, all the while laughing like a maniac & spewing four-letter-words at the ones that get away. I'm thinking it's only a matter of time before I see a video of myself on youtube. By the way, nothing chemical has worked. Not the grub treatments to the lawn, Sevin, Merit, garlic-water spray, soapy-water spray, zero. The only thing that works is annihilation via thumb and forefinger. It's a lot more satisfying, too!...See MoreFirst Japanese Beetle today!
Comments (11)Let's see, I posted on June 14, and 1 week later they arrived. And boy did they ever arrive. Grrrrr. I'm still using the soapy water method. Went out hunting for the first time yesterday and got around 100. It was during the afternoon though when they're friskier so I did lose a good many too that flew away. There were definitely some on my knockout roses and my Golden Showers climbers but their main love this year seems to be the Wisteria tree I got from someone at the swap a couple years back. And also the wild blackberry bushes which I don't remember being a fave of theirs in years past. I couldn't give a flip if they eat those but I know if I don't kill those as well they'll just breed more. It kinda' sucks 'cause those blackberry brambles around the edge of my property are large and hard to get into without getting pricked. Say, anyone have a flame thrower I could borrow? Tomorrow I resume the hunt for my quarry. Danielle...See MoreSaw my first Japanese beetle of the season
Comments (8)DiC, LOVED that hungry beetle drawing! Nippon beetles have not (shhhhh) yet been a problem here. Perhaps all the heirloom Marigolds i grow? Now the almost look-alike rose chafers r another bugger entirely. Two years ago they ate all the flowers offa the climbing Hydrangia vine. Last year they *really* P.O.'d me when they finished with the hydrangea and moved down-field and ate all the blossoms offa my grape vines! The local extension agent started to explain all the chemicals i could use, and suddenly my cell phone signal quit (oops). Since they r apparently a cyclical problem, I'll wait them out (like voles). This year no big problem, had climbing hydrangea flowers, grapes are about to be ripe, and unlike last year, the apple trees are very productive (my shoulder is *SOð sore from twisting the food mill putting up apple sauce). To every season, turn, turn, turn...See Moretomatoz1
