Spider mite and diatomaceous earth

First bout with spider mites in a loooong time.


Everyone has all these fancy remedies. I’m going use diatomaceous earth dust only and show how easy it can really be.
Will start the show first thing tomorrow morning. Will document everything.
See you then.

I typically dunk in sulphur for most pests. Interested to see this approach. You seem confident lol.

DE worked on my outdoor plants when I was still growing out there. I have confidence in this too

‘Neoseiulus californicus’, used these predatory mites last year in flower, used this season again in a greenhouse.
Fantastic results…not free…it’s the shipping that hurts. This year I have refreshed them every 3 weeks and added in ‘green lace wings’ too.
I purchase from ‘Naturesgoodguys’.
Ran the vegetable garden with beneficials too this year, saved my leafy stuff.

DE is fun. you get this white powdery dry spot where the thing used to be. kinda hilarious. if your RH% is down, and the VPD is over 1. they’ll dry out.

I use a mix of Peppermint/tea tree/rosemary/clove oil, and water. in a spray bottle. gets most that stuff out. save the neem for veg and the roots. and also pyrethrins.

DE is also a great source of Si for the plants, too. get some nice strong branches. I need to top dress some DE on my plants. i’ll mix it in with some bone meal. they’re like week 4 of flower.

Looking forward to see what you do! I end up spraying safer’s end all every 3 days for a few weeks and that really fucks them up. :smiley:

do you use that when plants are in flower as well?

Because I was a delayed a bit, but didn’t want to just let them multiply overnight…I gave a good dusting before bed.

Leaf stripping to the extreme…and then brushing on the de…on every piece of the plant.

I personally don’t like DE simply because once it gets wet it is useless and then has to dry out to do it’s job correctly.but also does nothing for the eggs so it is always a continued battle.

Good luck with your endeavor! I’m not saying DE doesn’t work, I am saying I personally don’t like using it.

Will leave de on for now…might spray it off in a week or so…baby mites should be finisjed hatching by then. Larvae wont be able to hack this. Lots of plants werent affected by the looks of it…so may have caught them before too much spreading.
2 weeks and possble 1 reapplication in between is probably enough.

6 days to hatch
3 says larva stage
3 days nymph stage
Any adults already removed (deleaf) or hit with de…wont last long.
So 12 days from egg to adult. So ill give a 14 day treatment to be sure.
