Best thing to do is what @Dr. Who said. Use multiple remedies in staggered applications.

Mites are tough. If you get them the best thing to do is go on a very aggressive offense and then a very aggressive defense.

The real mite issue is RUSSET mites!

There is NO amount of home made juice that will even control these fuckers long!

You have to get out the big guns (if you have to save that strain)....

Just beat down a Russet issue with 1 round of Forbid, followed by 1 round of AVID....
This was done at the veg level only....Whole building was cleaned and I haven't had a return....

The difference was 1 application of 4F and then 1 of Avid. 7 days of waiting, and repeat.
All media, containers and floor. Where hit with a contact killer (pyrethrin) at each application.

Many bug kill failures. Are from forgetting to treat media surface, containers and floors...They ain't just on the plants kiddies!

Use the right stuff, the right way....boom done....

I forgot about this thread. When I had them in my greenhouse this summer, I also used mite massacre and I think it's called green cleaner? Anyway it was a tough battle that went on for almost two months, but I won. Once they were gone I was still really paranoid and expecting them to pop up again. But I always sprayed the pots and surface of the soil like doc is saying. ^^^

Actually as far as that goes I would also spray a good size ring around the base of the pot, making sure I got under the edge of the pot.

Very interesting. I will be looking into that.
I have "grow strong and healthy" written on a spray bottle of plain water. Its the law of intention. Or something like that.
There was a Japanese scientist that froze water that had different words written on the jars and he put thoughts towards the different jars. And the patterns of ice crystals were beautiful and symetrical when good happy words were used. The other jars with words like war, hate, death, those water crystals were asymmetrical, deformed and looked ugly.
I don't know if it helps. But it definitely couldn't hurt. I want to do the same on rain barrels and watering cans.
People also say talking to your plants helps. And others say that the plants mimic their emotions. If they are positive there plants look happy too. And if they are negative their plants look droopy. I think there is a lot more then just NPK that goes into a good grow.

"The lessons here are basic to understanding scientific methodology. In order to avoid p-hacking (getting the results you want by tweaking the experiment) you need to use rigorous methods. Sample sizes need to be large enough to have statistical power. You need to determine before the experiment what the outcome measure will be, how long the observations will be, how may subjects there will be, and what kind of analysis you will make. You cannot make these decisions after you start to collect data, because then you can easily subconsciously p-hack the results.

Emoto gives us an extreme example of this. It shows that there is no hypothesis so ridiculous that you cannot p-hack your way to an apparently positive result. This is an important lesson for serious scientific researchers, to remain vigilant against more subtle manifestations of p-hacking."

I don’t think mites will get immune to rosemary oil. Never used essential oils for mites but most of the homemade remedies, as far as i know, work by covering the mites in oil and suffocating them or by stripping their waxes and dehydrating them. Unless there are other secrets to rosemary, besides being a repellant, there shouldn’t be any immunity imo. But anyway, can’t make claims at this point.
That being said, i like NeemAzal. Its pure azadirachtin extract mixed with organic vegetable oil. So it kills both on contact and it also provides systemic protection.
And careful with essential oils, they burn easily. Comes from experience.

1 teaspoon of citric acid dissolved in 0.5 L of water
Yo, are you using any sort of spreader sticker with the citric acid? Or does the citric acid and water combo do the trick alone. I'm hopeful this could be the go to mid to late flower bug control. Seems to be the most effective non invasive, toxic bug killer I can find. Everything else has oils or chemicals in it. Thank you

When I used it I just mixed it with water and didn't use a surfactant. It was years ago and I was midway through flower. But it killed most of them. If you decide to use it make sure to test it out on a small area before spraying your entire grow. Good luck.

"Citric Acid for Organic Spider Mite Control
Citric Acid is a colorless, crystalline carboxylic acid found in almost all citrus fruits and plants. This acid was first extracted in 1784 by a Swedish chemist, but not until recently has it been used for the control of many insects. Citric acid is a contact killer and needs to be applied directly to the insect to be effective. Since it is an acid it can be harmful to plant material, so use it in a weak mix. Citric acid is often mixed with Isopropyl alcohol to make a spray that dehydrates and kills on contact. Orange Guard makes a water based spray or you can most certainly make your own. Simply mix around 3 teaspoons of powdered citric acid per quart of water and spray the plants, particularly the undersides of the leaves where they tend to congregate."

Years ago I had extreme infestations of spider mites growing in a basement. I made my own rosemary based miticide. It worked for awhile but they always came back and then eventually seemed to adapt to it. I would never spray eucalyptus oil on a flowering plant.

Citric acid kills them as well without leaving an oily residue.

You're recipe is fine for veg but it can impart a flavor to the buds if sprayed during flower. But as long as the plants are vegging spray away until it's running off the leaves.
Haven't experienced mites yet (3rd grow inside) but I do thank you for the Citric Acid tip!
I use 1/8th tsp of powdered Citric Acid to a gallon of tap water to get a good Ph. Goes from 7.7 to 6.3
Also gets out stains well, in the washer machine. Use 1/8th cup

Hey everyone, just wanted to share with all my fellow growers a nice little trick to kill those pesky Spider Mites instantly. I have a Hulkberry 5 weeks into flower and noticed a few white spots popping up on lower leaves and sure enough after thorough inspection with a 100x microscope there a few were. So let me help you out.

Simple shit.

1tsp Pure Rosemary Essential Oil
8 oz R/O or Distilled water

That's it. Shake generously and apply. You can also add a few drops of Eucalyptus Essential Oil also, the thinner properties of the Eucalyptus oil allow for a smoother coating of the leaves without having to add a carrier oil or soap, as well as contains an antisceptic property. You can even go as far as to add 3 drops of melaleuca (tea tree) and 3 drops of lemon essential oils as they contain antifungal and germicidal properties. Powder mold, botrytis, most mites etc.

If you don't believe me, take an infested leaf and shake some onto a white piece of paper or if you can see them with naked eyes or microscope, then finely mist them once and watch them all stop dead in their tracks. Used Rosemary for years, doesn't effect the taste of the buds if you stop 1-2 weeks before harvest, and you don't need more than a super fine mist, instant contact of the Rosemary will kill them, you'll see them walk into spots of it and stop moving instantly. Try it out.
thank you Chevy,iv been looking for a bud safe organic way to get rid of those schorge of God,great drop of knowledge,thank you
