From a fellow grower-Customer has tried all of our tips for getting rid of spider mites, spraying with water, hoovering, etc, and still has them, any more ideas for getting rid of spider mites?

Capt. Jack’s Deadbug is a good solution that can be applied in both veg and flowering.

if not further than 3 weeks into flower, then I would suggest doing a sulphur burn. I had a major F%&*%$#ing russet mite infestation and the sulphur did the trick. In fact, it will kill all pests and including WPM too.

Lol, this is what happens when vacuuming and not paying attention in the grow room

I use hydrogen peroxide, peppermint oil and dish soap. But you need to spray constantly to break the cycle as they reproduce every 3 days 
. You could just take a hit, kill everything and do a sulphur burn. They’re a nightmare. If you’re hoovering make a tube extension with a hole in it and hoover through that. That way you can control the suction by opening and closing the hole 
It doesn’t seem to phase mine at a rate of one tablespoon per quart spray bottle. I spray with the captain, then look through my loop and they are still crawling like they liked it. Next day no dead mites. I got a serious problem in one indoor room.

@Davyg can you give me your mixture ratio per quart spray bottle as I’m having a major issue myself as mine seem immune to Capt jacks

I spent quite a bit of time researching after they showed up in my tent grow and what worked for me was 20 shakes of an essential oil into a spray bottle with a 1/2 teaspoon of castile soap sprayed twice a day, rotating to a different essential oil spray every three days. I used rosemary (most recommended on the internet), tea tree, mint and pine. I was able to get ride of mine in two weeks. Other oils recommended were geranium, citronella and clove.
I sprayed before lights on and after lights out making sure to coat the undersides of the leaves. I also sprayed the soil surface, the grow container and the interior of the tent,
Also two growers on the forum have used diluted isopropyl alcohol or a mix of garlic and hot peppers (made like a tea) and strained to use as a spray.

I use a 1.5 gal sprayer with 2 teaspoons of dish soap and 12 drops of peppermint oil. It kills them stone dead every time 
Peppermint oil is toxic to spiders so it helps as a repellent

It’s an interesting read and gives a fair bit of insight into the why’s and the wherefores of essential oils
