Hey guys, im just cleaning out the room, my girls have spider mites, at the moment its not too bad, just a few marks on each leaf or so. I have been recommended 'SAVONA' which is spider mite killer, i was told to fill a bottom and dip my plants in, but i forgot to ask a mate if i should spray the grow tent room with it?

so should i also spray the room with the anti spider mite?

i've given up with prevention methods with spider mite

have used neem, garlic, predator mites etc etc

they all work, but i've found the easiest method (and most enjoyable method!) is to keep an eye out for the tell tale pin prick marks on my cuttings then use my fingers to SQUASH the bastards!

you will be surprised how FEW mites there actually are on your plants when they are cuttings

i'm not talking about a full on infestation on flowering plants here, but having some mites on your cuttings which consists of 4/5 leaves, they're very easy to spot and get rid of at that stage

its a very enjoyable, highly effective way of getting rid of both the mites AND their eggs

they arent cuttings, they are 4/5 week vegged plants about 3 ft tall

well, you could still do what i proposed before, but you won't get them all and it will take ages

personally, i've found predator mites to be the most effective on larger plants, though not everyone gets on with them

you have to be a bit careful when you order as they only survive a day in the post, i think these people send out on a wednesday for thursday delivery, so you need to be around for delivery

SPAM REMOVED

in future, try to deal with them when the plants are smaller, it is just so much easier!

Just get some Harka Mectin, job done

havn't heard of that one, but yeah, there's loads of chemical treatments you can get

i prefer the predator mite's because the plant/garden builds up its own little eco system, good bugs eating bad bugs and good stuff like that

i've always been under the impression that the non-biological treatments kill EVERYTHING on the plants which is not necessarily a good thing

but then i've various larger spiders who live in harmony with me and my girls in the garden so i may be biased!

Harka mectin costs £8, will work in both flowering and the vegging stage and will provide hundreds of sprays, predators cost £20 upwards for a single application that may or may not work and never work in 12/12. I know which one I'd spend my money on

Do a search on the site for Ivermectin and you'll find plenty of information

2nd that .. i have been clean from the borg for a while now thanx to Felix and this lovely stuff. I sprayed every 3 days for the first week and then changed to once a week for 2weeks.. They where pretty much gone after the second application, i kept reapplying for another 2weeks just to keep on top of them unhatched egg's. Highly recommend.

already dipped the girls in a bucket of diluted savona, thanks for the advice.


btw, to spray the room .. or not ?

can spidermite live on walls of a grow tent or on the floors ?

They can live on walls and floors but need live plants to feed. Bear in mind that Savona is only a contact killer and won't kill eggs. Whereas any of the Mectins will hang around in the plant tissues and kill any mites that feed over a 7 day period, after which it is no longer harmful. Given that Mectins are only translaminar and not systemic you don't have the problems of them moving all over the plant and getting deposited in the buds, it stays right where it was sprayed.

i would or wash the room with a mild bleach solution wont hurt
they will be in the cracks of walls and carpets

Get your plants out and if you can get your hands on a steam cleaner tis awesome! Kills mites and eggs, my mate didnt listen and now has a house infestation hes tried predator mites, savona, garlic spray just about everything in fact. Nip it while you can mate

i used plant vitality plus ..supposed to be organic and kills mites on contact also kills eggs and larvae and prevents a reoccurence of them ..well i gotta say i cleaned my greenhouse of them and all the plants in there on first spray ..used it again a week later to be sure but couldnt see one mite ..it also greened the plants up as its a stress releiver too ..i cannot reccomend this stuff enough ..brilliant stuff .thansk to the guy on uk420 who told me about it .

What's the active ingredient in that Vince ?

Now THERE'S an image I didn't need on a Friday evening!

But 'what he said' about Plant Vitality Plus - even though 'the whisper' is, it's not quite as 'bio' as some claim, I believe it actually has mectins in it. which does zap the fekkin' borg.

This is the problem, no one knows what's really in it,could be anything really. When spraying my plants I like to know exactly what I'm spraying them with, particularly for something that will be smoked or consumed

I used to get spidermite I bleached the walls and added a layer of polystyrene (Now celotex) insulationg between the walls and my grow area. Never seen a mite in over year touch wood.

I do use SBPI regularly in veg but never in flower.

marka hectin is used to deworm pigeons..... i dont think im going near that.

Yes Mectin's kill worms just as well as they kill mites

Felix.. where can i buy some marka hectin please?

it doesnt say on my bottle and i keep checking online to see if theres any more info ..so im gonna have to guess at lard and donkey wazz ..if thats wrong then dont quote me ..

It doesn't list the active ingredients ? So there's no way to tell exactly what's in there then organic or non organic, safe or extremely harmful ? I notice in this post you mentioned it was organic and safe to use up to 6 hours before harvest. Just wondering whether you still stand by that statement when you don't know what chemicals are present in the spray ? Surely any pesticide for sale in this country has to list the active ingredients in case someone was to accidentally ingest some of it and need medical attention ?

I don't think I'd feel safe using a spray that I didn't know what was inside, could be any number of unpleasant and highly toxic chemicals.

Sorry man not having a go at you but it does seem extremely irresponsible of the manufacturers to me in not listing what is in the bottle, for our own safety. Unless they have something to hide that is



Hi Sam,

It's easily available online from pet supply type places as it's used to treat pigeons there's no obvious canna connection and you should be safe ordering it

Thanks Felix.. i take it you just spray it on the plants all under the leaves and that? Should i spray it around the room too? And how much should i use per litre. Sorry for all the questions mate i'm just panicing

About the marka hectin, im sure it does work, but the question is @ the end of the day I don't want to be smoking some pigeon dewormer if ya know what I mean or anything from b&q made in another country with all sorts of polluting chemicals.



Anyways thanks for the advice, the savona is REALLY strong stuff. but I have just discovered weeks later that it's not spider mite, its actually thrip because their are alot of marks on leafs on every one of my plants, Thrip are not air bourne yet so im lucky, the infection is not as bad as i've seen around on the net so im greatful.

What do people recommend for thrip then ?

i got mights 6 weeks into flowering. i used dish soap and water and sprayed the plants daily never got rid of them but they didn't get worse. good luck man.

Hiya mate, take a look here -

http://www.uk420.com/boards/index.php?auto...showarticle=482

Depending on what stage your plants are at I would go for the "Safer Soap and Scotts Bug Clear Concentrate (From B&Q) Mix it up according to the instructions on the link and give your plants a good spray at lights off. Close your vents off and turn your extractor/fans off for the night. In the morning about 30 minutes before your lights are due to come on turn your extractor fan and oscillating fans back on to clear the room before lights on. (This is a great method for vegging plants)

I have used the Scotts Bug Clear in the bottle (already mixed) and found this to be highly effective and it killed the thrips first spray but I did give my plants a blast of the concentrate stuff mixed with the "safer" soap (order that online, google is your friend) before they went into flower just for good luck really!

If your plants are in flower then I dont know what to suggest. People say cover your buds with plastic cups or something and then spray the plants but it depends on how big your grow is I suppose. Make sure you spray UNDER every leaf aswell, really drown those fuc***.

Oh yeah, sticky traps (they say blue for thrips but I havent found any yet) aswell. Put them around the room to catch any rogue adults which may have appeared.

If I was you I would try and get on top of it if you can. My mate has thrips and was too late in identifying the problem and he reckons he has lost about 20-40% yield

Good luck mate but caught early enough I think you will be ok. Some great advice from OT1 on that article attached

Ot told me use this for thrips, Dynamec containing abermectin as an active ingredient,.i cant find it here where i am but if you can i would take it.

And if manufacter didnt state what ingridient is inside its not a good product to use IMO!

thanks for the advice, Went to local shop today, picked up some 'pest off' supposedly really good stuff. but expensive

told me thrip are difficult to get rid of because they grow larve in the soil.


they are defo not on the leafs on my plants and I can't see any of them during lights on.

ill keep ya updated

If they are thrips they are on ya leafs i teel you. They are walking all over my plants,especially under leaf

yup just took a look at lower growth, covered in em, some dont move so they might be dead, some move pretty quick, pale white.

'Pest Off' Derived from pyrethium seems to have killed them all/95% of them.

very happy with that product. will continue to treat

The Harka Mectin will see off thrips, I can vouch for that.
Tried several things that were part effective.

It's worth taking the plunge if you want quick results.
Follow felix's instructions for treatment against mites.

It's got it's place in my armoury now.
Convincing win, thrips 0, me, happy boy.

Nice one Mentiras I didn't know it was effective against Thrips as well, just goes to show how important experimentation is

Had spider mite for months destroying my girls. I tried everything only to find the little bleeders must be immune to everything other than a Nuclear warhead. Eventually used SMC from spidermitecontrol.com which is part of growth technology. This is an oil which suffocates rather than poisons and touch wood they are no more. I paid £13 and this made 4 litres of spray which left the leaves nice and shiny. Plants suffered no harm but the mites did. Worth a try if you're pulling your hair out.
