Carol, I didn't realize until last year that grubs were June Bug larvae! I hate grubs, and I find tons of them in the garden. Which is why I probably have so many moles.

Carol, Are these the green June bugs? Japanese beetles? Brown chafer beetles? All that I saw in the video were the brown June chafer beetle type that we often call May beetles or June bugs and I'm not sure that Milky Spore would work on them. I think that Milky Spore largely works only on the grubs that turn into Japanese Beetles, which we rarely if ever see here in Love County. (I did use milky spore powder and beneficial nematodes shortly after we moved here and they seemed to put an end to whatever white grubs were eating our grass. I didn't use it in the garden.) Whatever y'all are seeing, we don't have them here. I think I saw 1 or 2 in June and that's it. We did have the brown chafer beetles hatching out in March and April when we were insanely hot here, but even then, not in huge numbers like y'all are seeing there.

All white grubs are not the grubs of Japanese Beetles, so the milk spore likely would work on those grubs, but not on other white grubs. In this part of the country, we have dozens and dozens of beetles whose larvae are white grubs of various shapes, and most of them are not harmful. The ones we find in our garden beds usually are the larvae of beneficial beetles. The ones found in turf grass can do a lot of harm though. For those, I think the proven control is something chemical, other than applying beneficial nematodes to the soil, or beneficial nematodes plus Milky Sport if you actually have Japanese Beetles. Since I don't use those chemical products, I don't know what ones are listed for white grubs....but probably a lot of the granular pesticide products applied to soil and watered in would be listed for control of white grubs in lawns.

The time to treat for them here in our state usually is 5-6 weeks after the beetles emerge, so roughly beginning sometime in mid-August. You likely would be able to treat anytime from then through the end of September, but I think the earlier timing with that time frame then the better the results will be.

We don't have them in our lawn, so no problem there. When I see white grubs in the garden, I tend to ignore them since probably 90-95% of those are likely to be the larvae of beneficial garden beetles which feed on organic matter in our soils. Sometimes, if I find a ton of white grubs in the garden soil when I am planting in Spring, I'll feed some to the chickens, but more because I figure there's so many that I can spare some to give the chickens a treat than out of any concern that they'll damage plants.

Some years we do have tons of those brown chafer beetles in May (sometimes April, sometimes even earlier in hot springs) and my favorite way to kill them is to put a 5-gallon bucket filled with water underneath our outdoor security light. I add something to the water in the bucket to attract them--compost or compost tea, manure or manure tea, liquid molasses, alfalfa or alfalfa tea, Garrett Juice, liquid seaweed or fish emulsion all work very well. I come outdoors every morning to many dead beetles that have drowned in the 5-gallon bucket. I scoop or pour them off the top and leave the bucket there. Night after night it attracts bugs and morning after morning I find tonds of dead beetles floating in it. It is one of the easiest forms of pest beetle control I've ever found, and I discovered it by accident. I was making some sort of tea to use as a plant tonic--might have been alfalfa tea, compost tea or molasses tea. I left the bucket sitting in the sun to brew the tea for a few days and found it full of dead beetles. It seems like the outdoor light attracts the beetles and then, for whatever reason, they feel the need to fly into the liquid in the bucket (not sure if they want to drink it or swim in it) and they drown.

Please note that I would not leave a 5-gallon bucket sitting around full like that if we had small children or small pets who could fall into the bucket head-first and drown. I'd probably cover it up with a snap-on lid all day and uncover it at night after small children and small pets were up for the night.

Often, when I pour out the dead brown beetles, the chickens do come over and eat them, but not always.

Hope this helps,

Dawn
