  • Japanese beetles?

    Does anyone have a problem with these beetles on large in ground trees? They cluster around figs and eat them, if you shake the branch the fall and fly everywhere including your face.

    they usually are attracted to rotting figs, then they start eating the good figs, they haven't bothered my potted trees because I pick fruit before they spoil. I can only eat figs off these large trees for a few weeks before there's so many beetles that picking figs isn't worth it.

    Any idea how to control them?

    Pyrethrin-based insecticides work pretty well against them. Also they typically cannot fly when the temp is below about 70-75F, so if you can get out early in the morning you can just shake them off and stomp them

      We're above that during the summer 24/7, I saw that but it seems that's after they've landed on the figs.

    Rue is supposed to deter them. I bought a couple of plants, but the figs are not currently attracting the June beetles to the yard.

      Those aren’t Japanese beetles. I believe they look like green june beetles.

        Yea those are not Japanese....I have a plethora of these and they do not bother figs or their leaves.

      They're fig-eater beetles, in CA people call them June beetles. I think you can make funnel traps baited with fruit juice or overripe fruit for them.

      Back east we had a big black beetle we called June beetles and also actual Japanese beetles. Regional common names can be so funny.

        Green figeater beetles! If I didn't grow figs I think I'd actually like these colorful cartoonish creatures. It's amusing to watch how creeped out some people get when these noisy fliers buzz them.

        Now down to business. I've tried some traps but they were almost useless, baits that others said worked for them didn't work for me. I've noticed that they like being in the tree. If I take the same fermented figs they were feeding on in the tree and put them in a container almost none go for it. They seem wary of being trapped inside of a container.

        Things that seem to partially work for me: 1) pick them by hand 2) remove most of the spoiled fruit 3) cover figs with organza bags

          I've been trying to avoid the organza bag route as that means I'd have to cover hundreds of fig. Just going to have to suck it up.

        Thanks for the help everyone, best bet is organza bags which is a pain.

          We get lots of Japanese beetle damage here, but not on fig trees/fruit.

                Put a long piece of 2 or 3 inch PVC pipe on it. I use a 20 foot joint and longer for vacuuming up bee swarms out of tree tops. Look up "bee vac" for more info and DIY. Works for wasp nests and stuff too (just make sure you wear your bee suit ;^)

              When figs start to ripen and the June beetles arrive,I have to walk down the rows of fig trees collecting the June beetles in an empty wide mouth Duke's mayo jar and then dump them in a larger container of damaged or spoiled figs.I leave the container in the sun.The heat kills the beetles and I feed the dead beetles and bad figs to my chickens the next day.The beetles will cause a lot more damage to your figs if you don't knock down their numbers when first detected and daily.

                There you go @DeWalt, the fanny-pack beetle-vac could be the hottest addition to your cordless combo kit.
