spider mites killed easily and for free

[mouts]

im planning on takin some cuttings off my guerilla plant and growin them indoors. Does anyone have any suggestions of what to do with them before bringing them in, to make sure they dont bring in any pests? Thanks

I have yet to have any issues using tobacco sprays,, no mosaic virus issues...I never used ciggie butts that's funny.....regular tobacco unsmoked of course

 

[Photosynthesis]

Tobacco mosaic? Is it real and isn't this how it would spread. I heard only really shitty tobacco ComPanies sell infected tobacco though.

My thoughts exactly. I know of a 400 lighter that had it, and the growers were heavy smokers.

Could have been a coincidence, but maybe not.

hey mouts, mites don't like cold, if you don't wanna get tobacco? (or were you burning the filters?) smoke all over your plants just spray the bottoms of the leaves with really cold water. if your plants aren't flowering yet then a spray of pure 91%+ alcohol will KILL them. if you do this in flower it will dissolve all the trichomes...

thanks for the tip! And i just lit a cigarette and let it burn away to kinda fumigate the plantS.. I have heard of ppl using nicotine foggers so thought its worth a try

I would strongly advise you NOT to spray 91% alcohol while you're lighting cigarettes. I'm being fucking serious as well. Whether this thread is serious or a wind up, which I think it probably is, anyone reading this should know how seriously fucking flammable 91% alcohol is.

The vapors from it can and will ignite if they find an ignition source, such as a lit bulb or lighter, and if they do, you are NOT putting the fire out! it's as simple as that.

Be every bit as careful with ignition sources when using 91-99% alcohol as you would pouring fucking petrol on your plants. It's easy to underestimate how dangerous these things are until you've seen the effect of a very small amount of vapor igniting. A whole room? I don't even want to think about that.

I'd rather keep the spider mites as pets than do some of the things suggested in this thread...

 

[Budley Doright]

There are actually many links about nicotine and spider mites....


However none recommend using raggedy old used butts......lol

 

[mack 10]

please stop the smoke treatment's,you will kill your plants or disease them.
if you must use fresh tobacco, pref organic.

 

[Photosynthesis]

Essential oils will kill them cheap, and also help prevent pm and such.

 

[meadowman]

preventive maintenance, don't let em in.

I have no mites from long time, but I clearly remember I had success against them using capsaicin. However mites can become resistant to it in few generations, so the best thing as usual is a rotation of different active ingredients.

The best way to use it is to fumigate and it's pretty easy to do, putting a concentrate oil in a humidifier. Few drops of oil and few drops of soap (I use a yucca extract as soap) mixed to water and then run the humid. in the growroom keeping air recirculation off.

Few hours of this (better all night long) kill 99% of individuals.

This technique imply an active ingredient and high RH (100%). It's impossible for a mite to hide from it once all the air is satured.

Capsaicin is obviously found in hot peppers. There are many ways to extract it, both using water (polar solvent) or oil/fats (apolar solvent). I do my oils for my own consuption, but every kind of fresh, dry, grinded or not, hot pepper will do the job.

There is no limit for the quantity of capsaicin to spray. It is not phytotoxic and it also doesn't affect taste.
Pay attention to inhaling satured air because it hurts to nose and throat, nothing serious however (capsaicin effect is only a joke of our minds).

Give it a try, it will work but don't expect to eradicate the problem with this. You'll probably can't without some other active ingredient.

Yes alcohol is VERY flammable and if you spray it near a lit cigarette its POSSIBLE that you might see a big fireball for a second. if you spray it into a flame you will definitely see a huge fireball for a second. it's cool if you're into fire like me. but your whole grow will not fucking burn down simply because you sprayed a little goddamn alcohol on the leaves. shit go spray some 91% iso on a hot bulb right now, it won't ignite. i'll wait.

even at 100% pure you can heat alcohol, "you guys" used to do it all the time. this line sound familiar to anyone "pour into pyrex pan and gently heat till alcohol has been purged" it's the fumes that you have to worry about with an open flame. alcohol being heated just causes it to evaporate faster.

so yes always be careful with flammable shit, duh, but your house is not gonna burst into flames and a fire that "you cannot put out" will not ensue. if it does manage to somehow cause an explosion i'm guessing your grow room is an airtight box, you can't have violently exploding fumes without pressure. same reason a firecracker exploding in a closed fist = missing digits whereas a firecracker exploding in an open palm causes mild pain.

alcohol itself burns off really fast, as we all know it evaporates at room temp. pour alcohol on a surface and light it, it only burns a few seconds unless its a pool, these fire challenges on the internet wouldn't have even make headlines had they known the difference between acetone and alcohol.

one burns a looot longer.

Jesus christ mate your advice has become so bad it's now officially life threatening.

If you spray 91% alcohol all over a room full of plants and it came into contact with a flame source such as a cigarette or lighter you'd see more than a "big fireball for a second"...

Instead of me going to spray 99% alcohol onto my bulb, go to the kitchen, take 5ml of it, put the bottle away in a safe place.. then heat up a pan. When it gets hot enough that water would turn to steam if put in, put the alcohol into it...

That is 5ml of alcohol. And that is a fireball for a second.

At the very least, if someone is going to spray all their plants down with 90 odd percent alcohol, take proper precautions and be careful.

I think in a thread where the fella is lighting cigarettes and leaving them in there after a spray down, it's at least worth a mention, don't you?

 

[dabking]

Darwin theory? If people can't put 2 & 2 together.... Boom

 

[stihgnobevoli]

a cigarette isn't an OPEN FUCKING FLAME which is what i keep saying but you keep ARGUING! flammable means it will burn, doesn't mean magic. alcohol burns, but it needs fire, or you need to concentrate the fumes to create an EXPLOSIVE situation and add a spark or a lit cigarette. then you will have an EXPLOSION...but still not a fire unless theres a lotta flammable shit (things that burn easily) inside your growroom. and unless your grow room is lined with loose tissue paper, tons of dry leaves and old oily rags, i wouldn't fucking worry about it. as long as you have some ventilation and you aren't spraying the shit directly into an open flame. YOU WILL BE ALL FUCKING RIGHT OK.

enough fucking fear mongering, do i need to make a fucking video of me spraying alcohol directly onto an HID bulb to show you it's not gonna magically burst into flames? my bulb might shatter from the sudden cooling, but i guaranfuckingtee it's not gonna cause a flame.

i went ahead and made 2 videos demonstrating the facts i laid out for you above. lemme know if you wanna continue this i'll make a fake youtube and upload em, or just accept that sometimes you don't know everything.

Like I said

[papaduc]

Btw, we use alcohol all the time, and other flammable or potentially toxic substances. But the reason I mentioned this here is because the fella is lighting cigarettes and leaving them to "fumigate" his plants... Just be careful, that's all.

 

[mouts]

i know now it was a bad idea to fumigate them i wont do it again. The plants are gone now anyway and i cant grow again until i move which will be in a few weeks. Next time ill focus more on keepin the grow room clean and preventing infestations now i know how fast they can take over.

just last night, i realised my plants had an infestation of spider mites. The leaves had white specks on them so I looked at the underside of the leaves and sure enough there were approx 2 or 3 small black bugs the size of a full stop on each leaf, as well as a shitload of eggs. I run a perpetual micro cab and the oldest plants are about 4 weeks from harvest, so i didnt want to use any chemicals and im also a cheap bastard so i did some reading and came up with this. First, i got about 10 cigarette butts from the ashtray and put them in a big plastic bottle with about half a pint of hot water, then i closed it up, put it next to the heater for an hour. Ithen strained it out through an old t shirt and poured it into a spray bottle and put it in the fridge til it was cold. Spider mites hate cold temps and moisture, so this is good. I put all the plants in the shower and sprayed them all one at a time very thouroughly make sure u cover ur face and hands and dont wear ur best clothes because it stinks. After that i put them all in a kitchen cabinet, sparked a cig and put in the ashtray along with the plants and shut the door. I have just checked them and all the adult mites seem to be dead. I will repeat this every 3 days or so until they are dead. Its not safe to use this method on food crops but as u are going to smoke the plants it doesnt matter.

Cigarette butt juice??

 

[mouts]

i just used what i had to hand at the time. It seemed to work without causing any problems. I never sprayed them with alcohol, someone else suggested it and everyone started arguing about lighting cigarettes after spraying with alcohol. I know now i shudnt have fumigated them at all. Im not stupid i was just desperate to kill the evil wee ****s asap.

Interesting note on the resistance to capsaicin. Was this an observed reaction? What type of pepper did you use? Carolina Reaper?

I used a mix of all my hybrids, mostly habanero btw...it has to be strong but every kind of hot pepper is good.

And yes, I observed resistance. Don't know in how many offsprings, but it was clear. I guess in 6 months from the first application they can become fully resistant (with average ambiental temperature) to capsaicin.
