Hey All, I've been having a problem with white fly & spider mites.
I read that a 50% solution of rubbing alcohol & water would knock them down. So I tried this a few days ago and "Viola", they ARE gone. But, I noticed some leaf curling, (not too extreme).

My problem is, there are at least 3 strengths of isopropyl alcohol on the market, 50%, 70% & 91%, these are all cut with purified water.
I used the 70% cut 50% with tap water.

Which one is appropriate? Anyone who has any experience in this matter, PLEASE give me some input, & thanks in advance, BB

I would like to know if you are still having success with the use of your rubbing alcohol/water mix to keep the white fly/spider mites off? I have spider mites getting on my entire grow room, and would like to be able to knock it out fast. Good luck.

hmm interesting. i know you can make organic pesticides involving garlic and jalepenos but maybe the alcohol is better?

I had this same issue with my babys and I found that using a small amount of dish soap with water in a spray bottle does the trick. Although some of my plants did die from this mixture, most of them have survived and are finally growing again after the bugs stunted them. Out of the 30 plants I had, 26 of them survived the infestation. I believe it also had something to do with the strain im growing (durban poison), i found that none of them died due to that fact that it is extremely good at fighting off infection as well as parasites, while the super silver haze i got had a few casualties. If you use the soapy water technique be sure to use it sparingly as it can cause browning of the leaves, stunted growth, or death similar to that of over-fertalizing and, or under-fertalizing. Hopes this helps anyone experiencing these little fuckers.

I have the same amount of plants but i only seen 3 plants infested i found them yesterday and i dint know what to do! so i went to my local nursery and got my self 100 LADYBUGS! placed them in my room and i sprayed the 3 plants the one's that i can see that had spider mite webs out of 30 of them! i sprayed them with Foxfarm Dont bug me spray!
I hope this doesnt hurt my plants what do you think about

1 Ladybugs for spidermites?
2 Fox Farm Dont bug me (spray)?

I will try the soap method should i wait for your methods since i did all this already (Ladybugs and spray Today!)
or do it right away?

Please help here are some pictures to see if this heavy or normal infestation! I cant belive i dint see them earlier?

to be honest with you i think the ladybugs will be kind of useless because of the size of the spider mites. Also make sure the spray your using is low in chemicals because obviously if u spray your plant with a non-safe pesticide it has a greater chance of dying. I'm actually suprised your plants look as good as they do considering the severity of the infestation but that being said they could have a better chance of survival because they were able to persevere through it for so long. As for the soap and water technique make sure u dont use a lot of soap and only mist the plants so they have a light film on them. The soap and water works in the same way as the sprays you can buy in the stores, by both drowning and chemically killing them. Make sure you dont do it often ether, check the plants every couple of days for signs of more mites. Also be sure to take off as many of the webs as you can so the mixture can reach the more problamatic sections of the plant. Also, if you can, you should move the infested plants to a different area to prevent further infestation. Hope this helps...keep this updated so i can see how they turned out.

fuck wut happened to caregiving ...caregiver..hah..damn did u try fighting them be4 they started all that webbing...that shit is gastly..no offense but im glad im not ur patient and buying that mite shit bud..


Rubbing alchol can def be used as a knockdown agent..i have a bottle of it sitting right next to all my other nutes..and miticides.. i wouldnt mix it 50 50 tho by no means..thats just me , and i think thats why u saw the leaf burning..i mix 2tablespoons into the bottom of a designated spray bottle thats like a quart size. but i would be using something like neem be4 u ever spot them..

GRWMM, Still not a sign of the critters, thank god. Tilemaster seems to think my
50:50 mix was too strong. However, the bugs are gone for 4 days now, & no viable
eggs to be seen. The leaf curling has dissappeared. So I guess I'm ok for now.
I will update this link as needed. Good grow to all......BB

PS: I would still like to hear from anyone with data on which strength of alcohol to start with
& what the final solution strength should be, again, thanks.....BB

What % of alchol you use 70?

50/50

I will try this too if the following doesnt work


What is this link?
It says use this mite for Spider mites
http://homeharvest.com/beneinsspidermites.htm

It finally dawned on me last night: if you want to know something,
effen "Google it". Keyed in: alcohol as spider mite spray.

Got: www.getridofthings.com/get-rid-of-spider-mites.htm

Halfway down the page is a paragraph on using alcohol. Check
it out and draw your own conclusions.

Good luck & good grow......BB
