Broad Mite Eradication

I know this topic has been beaten like a dead horse on here, I apologize for posting about broad mites again, but i have read the huge broad mite thread and havent had any luck killing them. Ive tried many things and still no luck. So I have been dealing with these since December. The first time i got them, I tried treating with alternate spraying of forbid and avid every 3 days, they would perk up for a day, then look terrible again. I cleaned out the room thouroughly, threw everything away. I bought a bunch of new clones, started from scratch. The clones I got looked kinda shitty, and I found eggs again quickly. I thought maybe my clone source was the problem, since I had a couple of this kids cuts in my previous grow. So I once again tore everything down. This time I cleaned extra thoroughly. I mean I wiped everything down (lights, ballasts, walls, ceilings, fans, shelf's, nute containers, tables, res's) with a 60% bleach mixture twice. I heat treated the room to 130 degrees for 12 hours 3 different times. Got rid of all my hydroton and bought coco mats. Bombed with a pylon fogger. did this all over the course of two weeks before i filled the room again. I got the clones from a new source, inspected them all thoroughly, no eggs. I alternated 2 treatments of each avid and forbid every 3 days since the first day they have been in there just in case, and also have a couple hot shots no pest strips hung, and everything seemed great. Sprayed my last pesticide treatment last monday, and then hit them with azamax a cpl days ago, I have that and a couple other organic sprays I was going to rotate as an ongoing preventative. But i noticed some twisty leaves, examined them under 100x scope and found eggs today (have never seen one of these little fuckers moving, only eggs). I sprayed with avid again tonight, but i dont have much more time in veg, i am running out of room, so i need to flip them soon. I cannot afford to throw out the whole room, 64 plants again. so my question is, has anybody had success with keeping broad mites in check enough to at least get a harvest? after harvest about to get the whole house bombed by an exterminator. obviously once they get flipped, i can no longer use the hardcore pesticides, so those are not going to be a viable option. Has anybody had success with predator mites? if so what kind? what about a sulfur spray? i have found bits and pieces about using sulfur, but i would like info from someone who has had success with using it. or if you have any original methods i would love to hear them. Any advice would be appreciated. I have never had so much trouble eliminating a pest before, and also I have never had one devastate my crop so bad. I have so much money in lately and absolutely no return. Im not gonna be able to sustain for much longer if i dont figure something out. Also i should mention its a sealed room with AC. no outside air coming in. Thanks

I kicked them out using predator mites and supplemental feeding of cattail pollen.

It took/takes 3-4 orders of predator mites, spaced 3-4 weeks apart, using a combination of quick release canisters and slow-release sachets, to get the job done. Swirskii are expensive, but cucumeris isn't. I used multiple types of mites within each order and didn't always repeat the same types with every order. Cucumeris was a mainstay though, as the slow-release sachets are reasonably priced.

Arbico also sells a predator mite food, if you can't find a high quality pollen source of a type that they'll consume. My source for cattail pollen dried up, for reasons unknown.

I haven't had broad mites since I wrote extensively about predator mites on this forum originally. Several months, now.

Check out the broad mite sticky. A couple guys were using 90% isopropyl alcohol.

I have read most of the broad mite sticky, but theres so many pages and so much contradictory information

That's a tough read. If they really are that resistant to avid and forbid maybe predator mites are your solution.

I have to ask, is there any chance you're seeing the bulbous immature trichs as eggs since you haven't scoped an adult? That would bring up offgassing and viruses.

These pests are really good at waiting till the next crop. I've tried everything and strong h2o2 spray is your best bet to kill any eggs hanging around

Indoors, heat wipes them out. 120 degrees F for one hour. AC off, no fans, lights on, with whatever supplemental heating source you use, whether it's more lights or space heaters. Trial and error to get to 120. Once you get to that temperature, they are toast. Try not to go over 120.

Yea they def arnet Trichs, they are still in veg and they are showing every symptom of broad mite infestation unfortunately. Im going to try the heat treatment Retro. Based on the broadmite thread, I heat treated the hell out of the room between clearing out my grows and starting new ones. I was hoping that I wouldnt have to heat treat with the plants already in there, but i am running out of options. Im not to worried about getting the room up to 120, i can do that no problem by turning of the mini split and throwing in a cpl of heaters. my fear is not going over 120. I feel like its going to be hard to maintain that level of heat without going higher. I also got some aspirin for the rez's, I could not find un coated anywhere, but the pharmacist assured me that crushing the pills up would negate the coating. I bought some wetable sulfur, but because i sprayed azamax a few days ago im going to have to wait to use it, since you arnt supposed to use sulfur for 2-4 weeks after using an oil based spray. I also have OGBiowar. Has anybody had success against the broads using that? if so how often are applications required? and ogbiowar works best at as close to 100% humidy as i can get, correct?

What measurements do use for your h2o2 spray?

I use a quart of 30% h2o2 diluted in 2 gallons of water in a sprayer; probably overkill but it works. If you're going to be in the room for a while wear a respirator it burns your nostrils

Thanks!! I just picked up an atomizer sprayer, i will give this a try. I appreciate the information

Don't listen to RetroGrow heat treatments don't work. You're wasting your time I tried heat and it's impossible to heat a whole plant up to 120f there will always be shaded areas where eggs/mites/larvae survive especially if you grow trees.

If Avid/Forbid didn't work you have not applied them correctly

Use them as instructed 5 days apart from each other in 2 cycles. 2 applications of each.. I dip clones rather than spray. Guaranteed eradication

Use heat to heat the the empty room


One problem with your post is you have not actually seem a live broad mite. What evidence do you have that you actually have them? Are you seeing translucent oval(ish) shaped eggs with small dots all over the egg? the plant twisting symptoms you are seeing could be from avid/forbid applications.. you are meant to apply every 5 days not 3 or you will suffer toxicity.

I got russet mites about 6 days ago in my new 8k room. First time ever indoors. About 4 plants out of 48 started showing signs. So of course I've been sick and depressed and scouring the broad mite russet might threads. I've been growing for 20+ years straight I've never lost a grow. It's scary sruff.! It's my bread and butter. It's what I do. I live in Hawaii and grow year round and when I get russets outside on my greenhouse grows ( which is rare ) I simply use one tablespoon of sulfer per gallon and spray and done. One shot. I have super mites here everything is magnified in an tropical environment. But indoors.? Whole different ball game it's the perfect environment for mites to thrive.
In my panic I went and got avid. Never used it before. Did 1.2 mil a gallon and sprayed with light's off and drenched them. The mites took that Avid and rolled a joint with it. Smoked it, and then made a porn vid. Shit didn't do a damn thing. The next day it was worse. And after reading the tons of people that have had no success with it or any of the harsh chemicals. I am not sold. Maybe on an outdoor crop which it's what it's designed for but indoors is not even in same category IMO.
The only success stories i found after researching for ever and sleepless nights is beneficial microorganisms. OG biowar it what was saving peoples lives so I have some already and decided to give it a try. It's working. And I mean working really well.!!
In a 5 gallon bucket with RO water. (Can't use chlorinated water it kills the bennies. ) add 100 mil of black strap non sulfer molasses. Then ph to 6.5 7.0 BEFORE you add the biowar otherwise u have to use half the damn bottle of ph. 6 tablespoons of the biowar then 2 cups of earthworm castings. I put it in a nylon paint strainer bag and it's nice a clean and doesn't disperse on the tea. Or u can use a clean sock. Put an air stone on it for 24 hours. When you're ready to spray Let it all settle for 15 minutes. Pore into sprayer slowly so the sediment stays on bottom. Spray when light's go out. Turn off dehumidifier. And drench the living piss out of the plants top to bottom, under leaves and everything. Let it sit in there and dry slowly. It needs humidity and time to start activating. Make sure it's all dry when light's go on our the light will kill the microbes. Do this for 4 days straight. Then 2 times a week once. Then once a week. I'm on day three and man, I'm sold. It's working like a merical. It makes sense, you create living spores on your plant and it eats the host. It kills PM and mold too. I have new hairs growing on the infected sites where it was just a nub.
So this is what I did after all my research. And I will do this for the rest of my indoor grows always. It's impossible for mites to get a tolerance to this. It spins webs and suffocates them. Unlike Avid and all the other shit people have tried. Fighting nature with nature. Winning.!

Pests suck. Lets hope the iso formula works eh? I need a miracle everyday!

Neem oil works very good for me

so my question is, has anybody had success with keeping broad mites in check enough to at least get a harvest?

i just did exactly that... my own situation was 2 weeks into flower before i realized what the issue was...all i did was nothing ...lol...i just road them out and much to my amazement the plants produced very nice tops...seems like broads & russetts like to camp low down? man they are microscopic mother f*ckers...good luck man

these broad? bulb? small they are

my Finnish friend metsakana

This is broad mite damage. Threw entire grow out. Used Snypes neem oil treatment on next grow, and never saw them again. You need a dispersant, and has to be made fresh.

to me neem seemed like water to them i used like 200ml and 50ml of essential oils and neudorf natural pyrethin with rapeseed. they just regroup next day and none off them die i can try to take picture or video how they look without magnification

now there is nothing in that room so i change soil and spray heat hole room and maybe clean it with bleach and vacuum

if mine were indeed broad mites they did not do damage so severely like that
