spidermite emergency

hi guys I'm looking for a little advice after coming back from a few days away my plants in the seed chamber are covered in spiders mites with webs.
these plants are literally just for seeds and should be a very nice cross breed and they are almost finished.
they probably have another two or three weeks to go but is there anything that I can use to spray on them that will kill the spider mites or stop them becoming worse?
my main concern is to have the seeds properly mature then I can cut them and sterilise the entire area properly.
I'm far away from anywhere that sells hydroponic supplies and in the past when living in UK I have always used Predators in this situation.
what natural and easily available remedies can you guys suggest that will just keep these plants happy without harming the seeds? could it be worth spraying with alcohol as I have some good 60% moonshine. I don't want to spray with any soapy solution as these buds are huge at the moment and Bud rot is the last thing that I need if I'm trying to maintain a good seed crop.
I might be able to get pyrethrum from a pet shop, but will this hurt the seeds, and does it make buds toxic?

I'd say your buds are already toxic with spider mite shit. You are in salvage mode now. I would slow the bastards down with a little dish soap water and try to salvage some seeds.

im trying the moonshine spray. the bugs have stopped moving instantly. will update on any other effects i notice.

Good luck with those little bastards... They almost ruined my outdoor plants last year.

If you just noticed them, and you have 2-3 weeks left ... they won't be able to kill your seed crop in that amount of time. Spraying alcohol on your plants might though.

Why tho?

How to use Moonshine Foliar Spray:
Moonshine Foliar Spray can be used on any plant being grown in any medium and system-type. It works very well on its own but when used in tandem with Moonshine Root Feed the results are particularly impressive!

It can be used at any time during the lifetime of an established plant, We would advise caution against using Moonshine on young plants (either seedlings or unestablished cuttings). Moonshine (both the Root Feed and the Foliar Spray) tends to encourage exuberant feeding which could cause problems during its vulnerable stages of life. Stick to using it on established plants during veg or flowering for that extra spurt of growth.

Foliar feeds are best applied at the beginning of the dark period when the lights have just turned off for a few hours. If intense light hits wet leaves then it can cause burning. Spray the whole plant, including the undersides of the leaves. Be careful not to get any on your grow light!

I never heard of spraying plants with 60% alcohol.
Seems like it could damage leaf tissue.

I had spider mites on an indoor ficus a few years back.
Tried a lot of shit. Put the tree in the cold garage for a week. That slowed 'em down. They don't like the cold. But it wasnt practical.
After a few months I just trashed it.

They can be a lot of work to get rid of... I had issues with normal plants outside as I say, really they are a headache to get control of... and then there is Ants... also a pain in butt!
