i have fought the borg in flower, and killed them all
used a similar formulation, contained rosemary, peppermint, clove, and another that slips the mind
wasn't easy, repeat spray, and repeat, these are oils you could spray on a salad
what do commercial greenhouses do? they get these little fuckers regular
food grade horticultural oil, cheap and available
coats them and they suffocate, they can not become immune to not breathing

I just released 4000 predatory mites.

I don't use only persimilis. The requirements on temperature and humidity to keep them alive are too demanding. I use a mix of 4 mites...

P. persimilis, N. californicus, A. cucumeris and A.swirskii

Hopefully, this will help with the survival rate.

Wanna see a battle between them.......

https://www.youtube.com/watch?v=MvDn...ature=youtu.be

EDIT: Oops. wrong video. Here is the battle scene....

https://www.youtube.com/watch?v=5YFJ16ufZSE&t=36s


For a predator mite, they sure got their butt kicked by the 2-spotted. I saw ONE battle in 15 minutes, and the predator lost. The 2-spotted walked away after a first round K.O. You could see stars around the Persimilis head like a cartoon.

Holy cow!!! Are these mites supposed to be aggressive?

The video is kind of long (15 minutes) but it took me that long to find a "predator" that wasn't either hiding under a rock. Or, busy running from a 2-spotted.

And, these are supposed to KILL my mite problem??? Doubtful. LOL

They seem to co-habitat well with the 2-spotted, simply walking right over the top of the 2 spotted. Well, the small ones. The Persimilis went way around the big 2-spotteds. LOL

It seemed like they fought among themselves more than against the 2-spotted.

Maybe I just got a batch that just got home from a big Thanksgiving dinner and they were not hungry. LOL

Well, I am NOT impressed. An inspection today shows no real reduction in 2-spotted mites but I can't find a single predator.

Has anyone had luck with ladybugs? I have heard that they work well but they inhabit the buds and die there. Several posts complained of having to pick ladybugs off the buds before smoking. I'm not sure if that's worse that mites but it's not great.

One thing that I did notice is that the leaves directly in front of the ultrasonic unit was almost void of the white spots that identify mite damage. Upon further inspection I saw no mites on the few leaves. I am going to look into this a little further with the close-up video and the mites and ultrasound unit in a closed box.

I think it might also be wise to test the CO2 theory in a closed box to determine if it's practical to try.

I definitely can't sit by and do nothing. I'll loose this crop. I either have to keep pumping money into predators or find something else that works.

If I make it to week 6, I can defoliate the lower leaves where much of the infestation exists. It seems, they infest the fan leaves first. I don't see them at all in the buds..... yet.

No-pest strips? Do they still make those?

CO2 fire extinguishers?

Laser guided Azamax cannons?

Got to be SOMETHING. I can't sit back and watch this beautiful crop go down to these fuckers.

I am going to order more pred mites for sure. Do ladybugs eat the pred mites also?

I wonder if fumes from something would work? Setting out a tray of chloroform might do something. I wonder what it would do to the plants?

I have a gig tonight but I am home all day tomorrow. I am going to clip some leaves full of mites and start subjecting them to some shit. Little fuckers have to be affected by something. Maybe high fructose corn syrup would piss them off. LOL

The Borg seem like they are born pregnant with the eggs. You need to spray them every 2-3 days for at least a week to get the new generation that comes from the eggs and interrupt their life cycle. I used a FPE of Lavender blossoms to kick them, and then sprayed the plants in the grow room preventative once a week for a year just in case there were any Borg left. I try not to spray during the bloom phase. Lavender smells good though so maybe I can use it in bloom?

I wish I could spray but if you look at my crop you'll see it's out of the question. These are a day away from 4 weeks into flower.

The eggs are EVERYWHERE. Fucking underside of the leaves are full of them. In 10 days, I am going to be overwhelmed. I will buy another 4000 predator mites next week. It's my only hope.

Fucking borg.

As for CO2 safety.... absolutely CO2 can KILL if it overcomes you and you pass out in it. I already have the Mrs. Ringodoggie to stand by and make sure I am not overcome.

Thanks for the warning and anyone trying this would do well to heed that warning.

I would think picking out ladybugs might be easier than the smaller stuff.
Best of luck for positive results.

I would consider spraying them down with 70/30 alcohol/water the day prior to using the predators, just to cut down on the numbers. It evaporates fast enough with decent air movement as to not be an issue, it may buy you time.

I am finding very little information and almost no posts on using a systemic approach.

Feeding the plants a substance that is undesirable to the mites but harmless to the plants (and me).

How about adding vinegar to your water? Or, some other 'organic' approach.

How about something like imidacloprid?

According to what I read it is effective on mites, is gone from the plant in 30 days and as for inhaling it.....

The acute inhalation LD50 in rats was not reached at the greatest attainable concentration.

These fuckers are NOT going to win this war.I am!
