Killing spider mites 2-3 weeks from harvest

Is it safe and organic up to harvest? I've read mixed things, but I did hear it works well.

I believe there is pyrethrin in it which has short half life. It was commonly used up to harvest before ingredients were disclosed. But I think two weeks is long enough but going from memory.
 
I'm my experience, I've used just a rosemary tea spray. I have had spider mites at the same time frame you have. It really is a bummer depending on size of your grow. I have a great local hydro shop that carries a product called SNS-217. I like it quite a bit although I feel whatever you spray at this point will show up on your smoke. They claim this product can spray safely until harvest day, which is true. But taste is there. It's basically a rosemary formula. I have soaked a rag and wiped everything down carefully and wipe the leaves. Wipe lights, fans, walls, everything. If harvest is close you can safely control them until chop.
The mightywash I have not used. However I hear great things about it as well. Do not remember anything about mightywash around harvest though.15010345671951570490838.jpg 150103459469730231610.jpg
 
This close to harvest I wouldn't spray anything on the plants. I would remove them manually as much as I could. Get a vacuum cleaner attachment and put a screen on the end to keep from sucking up the plant. Carefully vacuum as much as you can. One of those small portable vacuums works good because it doesn't have too much suction.
Prevention is the best method for dealing with mites. Once you have them they can be really hard to eliminate and will keep coming back. You will need to do a thorough cleaning and if you have plants in veg start spraying them with neem oil if you see mites or not. You're going to have to thoroughly clean the area you're flowering in when your current crop is harvested. Take this seriously. If you don't get on top of it you will be dealing with mites every grow. They like to show up in force just when the buds are getting ripe.
I hate mites with a passion. Nothing worse than being a couple weeks out and noticing webbing all over your buds.
 
if you can post pics, it would help a lot.

I have this horrible image in my head, with crawling underleafs lol.
 
Mites are the cockroaches of spiders. Resilient buggers. To RID mites, yes is a daunting task you most often lose
 
Anyone with a good Bomb product for when plants are gone, can I Bomb the whole grow room and be good for nest grow?
 
I am pretty well always dealing with mites.i have found the pest method is a good spray with mite killing spray.
before or when you bring plants into your rooms. and buying predatory, and preventers mites a few times a year, or when ever your loading up your veg room.
 
Green cleaner and flying skull nuke em are both very safe and effective at knocking those little bastards down. Green cleaner is basically safer soap with soy bean oil, citric acid and alcohol. If it touches a mite, it dies. Nuke em is similar, uses citric acid yeast and potassium sorbate. They claim you can even use it on product already harvested. My local shop said the nuke em is a little better for stuff further along in flowering. A few applications over the next week should knock the population down enough to get you through harvest.
 
you are screwed, Id try some manual removal, some ph spray stuff? and mostly temp control. If you get it cold they will grow way slower. Id also probably just make oil out of it. No pesticide oils- they will just be there in the final product. I guess Im rare thta none of my grows have pesticides.

It does but, at amounts so low it's not required by federal law to list it in the ingr.
At that ultra low amount. The pyrethrin is acting like a "repellent" and it makes the mites leave. Not even enough pyrethrin in the MW to kill!

In outdoor use. Pyrethrins exposed to the light and air. Only last about 24-36 hrs. If you have intense indoor lighting - Maybe 48.....

Nuke em is rather suspect in my book. They refuse to list the ingr. at their site and none are given for the MSDS - "Trade secret"

You have to get a wetting agent for it to work. This is fun.....

I do have to look at this stuff harder.
@vinny2times
NOW THEN.
You need to look to sanitize everything in that grow after you harvest. 1:9 bleach solution and spray down every surface - on - under - containers - ceilings - EVERYTHING! Now drop a bug bomb - Dr Dooms or even a bomb for fleas and tick's used for the house - same damn thing as Dooms bomb!

Make a real weak pyrethrin mix and spray every crack and around any door or window......Like I said earlier. This makes a good repellent. I respray monthly but, you can as much as you want.

I have not had mites in years - Good luck.
 
I've tried the habanero tea ..doesn't work, I use pest strips, hang them so there close to the plant, turn off all fans, both in coming and exhaust leave in closed room for about a week or do like the previous post but I use sns 209, it's also rosemary based mix it in your watering and feeding cycles it gets absorbed through the roots and disperses through out the plant, its safe and easy bugs don't like it
 
I made a thread aboutnit recipe to kill mites and thrips in veg and beginning of bloom and didn't get one single reply but try this next run; for 2L of foliar combine 100ML insecticidal soap and 250ML of isopropyl. It doesn't kill eggs so I suggest to spray every 7 or 8 days as part of an IPM. This recipe works very well...
