Spider Mites - Slay them all
Posted 27 December 2010 - 08:06 PM
So I'm in week 3 of my very first BB grow and I found a mite infestation. Webs were the first thing I noticed but it was already too late. Leaves were chewed, some were wilted. There were mites (tiny) on the undersides of most leaves of every one of my 12 clustered plants.
The mites are about half the size of a period ( . ) on the screen and mine are a brownish color. some are little closer to black and some are a little more white (young ones I assume). There are tinier white eggs that look a bit like res glands on the bottoms of the leaves. I noticed the eggs long ago but didn't think anything of them. They produce a web and chew the plants.
Immediately I filled a spray bottle with 40% rubbing alcohol, 60% water and sprayed the bottoms of the leaves as much as I could. Then I turned off the lights for four hours and increased the humidity as much as possible (sprayed water on the floors and walls). The next day I went out to get some hot shots vapor strips and a bug fumigator. I opened the vapor strip immediately and began hand picking off each leaf of a single plant (took about an hour). Today, that plant had no sign of live mites! So, I intend to go through each plant doing the same. Then if I am still feeling energetic I'll get my alcohol solution and rub Q tips soaked in the stuff on the bottoms where I see eggs. Hopefully this will allow me to avoid using the fumigator since ventilation will be an issue for me. I am lucky though, that this happened during my veg and I can basically do whatever is necessary to kill these guys. I'm keeping my temp down to 62ish and my humidity over 70% when possible.
A word of caution
I damaged my plants by going overboard with the alcohol. The reason the alcohol doesnt hurt the plants is that it evaporates quickly so that it isn't in contact with the plant long enough to damage it. I would recommend isolating a plant, spraying it like hell for 10-15 seconds (on the bottoms of the leaves) and then not spraying it anymore for at least a day. Or, you could use a lower concentration, like 25% alcohol and 75% water.
Where did they come from?
How can I prevent getting them again?
How can I get rid of them now?
How cold can I keep my plants without killing them?
Thank you for your help, ~Z

I used hot shot pest strips, organicide and temps @ 50 degree's high humidity.
The low temps and humidity should take care of them alone.
Organicide works, but any miticide you get at the hydro shop should do you justice.

Never take your plants outside and back inside, instant mites.
Never take clones from anyone before thoroughly inspecting them for any signs of mites.
Never let another grower into your room if you suspect they have mites. (never let anyone in period...)
You should keep mite free this way.

the eggs will hatch when the time is right for them not when your in flower
Basically the strip killed every live mite that I didnt kill by hand (squish) or by alcohol spray, because there are no signs of live ones left. I had 1 hot shots vapor strip out in the 10'x14' room for about 5 days. Then I put the strip into a ziplock and wait. There still are some eggs though. I'm told the eggs will hatch when I switch to bloom, so I'll reinstate the strip and hopefully be cleared for good! I am now a >FIRM BELIEVER< in these vapor strips. Don't waste your time or money picking them off, cleaning them, damaging your plants, or doing anything else. Just get a vapor strip for $6. In fact, spend the $6 just in case you might one day get them. It's that cheap and that easy. ~Z

I love the pest strips.!.!.! They work great for getting rid of mites and keeping em gone...but anyway i actually started to think the same thing so i started putting the strips in the room for a week then out for a week and so on...it still works good and i have a lil peace thinking i'm not poisoning myself quite as much..lol... if any one out there knows anything about the true stuff its made out off and the effects on people i'd be interested to know also...
well, the reason i took the strip out is that i got conflicting information on whether or not the dichlorvos (active vapor ingredient) is harmful to humans. since i spend a decent amount of time in my room, i figured put it back only when needed. Someone said the "carcinogen" word. What do you think? ~Z
