Hey there fellas, I recently have found some spider mite activity in my veg tent on a couple of autos I threw in there. I have pruned the sugar leaves which had lots of webbing on them and then sprayed the plants with a 1/10 alcohol water mix. Not ideal but its what I had available during the holidays. I have been careful not to spray the buds with the alcohol mix but i’m wondering if there is anything I can spray other than just ice water if I need to. Or anything else I can use to eliminate these mites before I move the CBD plants to the flower tent. So currently in the veg tent there are some photo period cbd plants and the couple of autos. Currently there is no sign of mites in the flower tent. id like to make sure that the mites don’t come in with the photos as there is sign of mite activity on them. Also other than predatory bugs and ice water spray is there any good way to save the harvest late in flower?
You could order a sample size of lost coast plant therapy, I’ve heard it was ok to use in flower as it’s just some natural plant oils. I have one sitting to the side should this emergency arise. My last run got hit hard in flower, so I turned everything into bubble hash, and everyone loved it! Even dried a few nugs that didnt have much webbing going on and they smoked just fine. Just be sure to give your room a really good cleaning with some bleach wipes after you harvest.
You can deliver a severe blow to them with Tweetmint. Check it out on the build a soil site. However, you will most likely need to invest in predatory mites to keep them in check when flowering. Although, spraying in early flower will not be a problem. Check out Soup’s IPM guide on Growerslove.com for some great info.
Treatment options in flower are pretty limited. (Which is why early prevention is so important)
Removing infected leaves and thining out the canopy can help keep them under control. You can use a vacuum with a hose attachment to physically remove mites from flowering plants too. Personally I’m not a fan of spraying anything once you’ve got buds forming. Predators might help but they are often slow to take effect and aren’t always cost effective.
Lots of good options for treating veg. Tweetmint works great. Neem oil is also effective. Main thing is to spray repeatedly and be really diligent about it. Spider mites aren’t that hard to kill, but if you miss any they will come roaring right back. You need to be as thorough as possible while spraying, and you want to be in there spraying every 3 days until you are 110% sure they are all gone.
And please check out the FREE IPM guide I wrote for cannabis gardeners! It will teach you lots of cheap and effective prevention techniques that can help you avoid this situation next time.

Here is something to try It will not eliminate them all but most will be gone. Plain water spray over a drain if you can move them. Then shake off has much water has you can.
Hi there.
Right , the ONLY product to really kill spidermites and their larvae /eggs , is a product called , Plant Vitality Killermite. It’s by plant vitality +. I’ve been growing for 20+yrs and over time we will all suffer the bane that is spidermites. I’ve tried EVERY product out there plus some homemade stuff I’ve done. Nothing ever worked, those little bastards would come back with a vengeance. Then I found the above product ( it ain’t cheap) and boom , like it says in its description, after 1 application they’re gone. And they stay gone. Seriously mate save your time and money and get this stuff. It works 100 % all the time.
Best regards. Thegreengrower.
We featured this on EP 956. Thanks for contributing!
Thanks all, I appreciate the feedback. I ended up getting the autos out of the veg tent and into quarantine to finish. Then some major defoliation of the vegging plants followed by multiple applications of Dokotor Doom 3 in 1 and it seems to have slowed them down anyhow. Ordered a “Grub Grenade” from amazon which had mixed reviews but we will see how it works. Thanks again fellas I appreciate the ideas and experinces
