Spidermites in Flowering

Engineer

Active Member
Hi, I recently discovered that I have spidermites. The infestation is bad. I mistook the damage from the mites for yellow pollen from some flowers I had growing in the room. Yesterday we saw them crawling around and there are little webs everywhere. The infestation has spread to the rest of the plants in the room. This is the bad part though... This is in my flowering room! I have plants in week 2, week 4, and week 6 of flowering. Unfortunately for me- the plant that brought in the mites is one in week 6- now all the plants have mites.
Is this crop salvagable?
I have read in the posts products used mostly in veg. I could shower the ladies to wash most of the crap off. I could go get more CO2 today to try and suffocate them but... I'm afraid that this won't be enough to kill the little bastards. Has anyone used the bug strip in flowering? Is it safe? What about a fogger? I'm ready to pull 'em I'm so worried...:sad:

ain't mites a bitch in flower. I've used alcohal/water 50/50 in the past but it didn't touch them this time. I got rid of them with hotshot spray and strips. Don't spray the plants. I used a q-tip and put it on choice fans. they where gone over night for the most part. Good luck.
 
your best bet is to find a good insecticide soak em down wait a few days and soak em again and see how they do after that is done. the bugs may never fully die so you have to spray plants down once a week. ive had this problem before and it is possible for the bugs to stay for a loong while without a powerful insecticide. your plants should be fine after spraying them and also it is during flowering that bugs will make theyre appearance so in essence you are supposed to spray them once a week up until 2 weeks before harvest. hope this helps :)

Is there an insecticide you recommend? I randomly use an organic one on my new soil but it didn't even touch these guys.

Fox Farm "Don't Bug Me" kills mites on contact and you can use it up until harvest according to the instructions. I wouldn't want to use past week 6. The only problem is that you have to spray at night so you need really good ventilation or else you might get mold. Azamax works really well but I don't know if you can use it on the 6 week ladies. Also, sounds like your infestation is heavy so you will really need to keep on them because after you kill the adults more eggs will hatch in a couple days. After your first spray, you should just get in there with ice water and a microscope and wage war. Just crush those bitches by hand...

Thanks for the recommendation! I do have good ventilation in the room so I guess I will be off to the grow store soon! Thanks!!

I had the same problem on my last grow.
What I did saved my plants. and had a good harv.

GO NOW and get some NEEM oil concentrate or pure neem oil. get a normal spray bottle got to your kitchen tap turn on the hot water wait for it to get hot tan fill 1 third full. than I PUT IN ABOUT 4 05 5 teespoons of NEEM OIL.
than fill the spray bottle up most of the way but leave enough room in the bottle to be able to constantly shake it up . so it will stay mixxed up. oil tends to sepperate from water and tghe consistancy will get all fd up. to weak in places and to strong in others.
spray them well befor the lights fgo out so they will dry befor the lights go out. and if you can turn up the ventalation do it till they dry and if you can add any fans to help them dry fast so the lights wont burn them. maybe even raise the light a lil till they are dry.
make sure the mix in the spray bottle is nice and warm when going on the plants so they soak in. to hot is not good to cold either. nice and warm like a bath.

do this every 3 days about 4 times and they should be gone. keep eveything clean and shower before going in the room to prvent contaminatuion they will get on you and back on the plants.

try not to soak your nugs but soak your leafs especialy on the bottoms of the leafs and stems
and try not to do any more spraying the last 10 days and flush for a minimum 7 days with ro water. youll be go to go.

:wall:
hope this helps

No prob.

Neem oil is all natural it comes from the neem tree or plant... whatever.. but its not a nasty cemical made in some lab.
it does have a fairly strong odor but that also helps to discorage the mites and other nasty lil critters from feasting on your lil ladies.
some others use a lil dawn soap with wam water and or a lil alchole and warm water. never tried those methods becouse the neem seemed to work good.
also if your tent or room is sealed put in some ladie bugs they eat lil critters or if you know for sure you have mites you can get preditory mites. they will eat the mites that are fukn with your ladies and not harm your bitches at all. you can order them from your local hydro shop and if you cant, find a better hydro shop.

You can get the already diluted Neem oil in the Garden section of Wally World for about 7 bucks or so. It poses as a fungicide/insecticide. I've not had an infestion thus far knock on wood, but I try to spray around the base of the plants about once a week just to be on the safe side. I also spray on the walls and floor etc.

Thank you everyone who responded :) After considering all advice this is what I did: I took the ladies out back and sprayed the crap off of them. In the meanwhile I washed the room down with a bleach solution. I put lady bugs in the room with the ladies and now I cannot see any signs of spidermites! Lady bugs are awesome!

well it sounds like your problem is solved but if you find em again try the no pest strips from home depot .i got 2 for my grow room (4x8x8) killed all my mites in 2 days. now i just put 1 in the room over night 1 night a week just to keep things in check . im 7 weeks in flower. im surprised theres not more talk on these things.they look like air fresheners $6.00 each...............

Can Doktor Doom Spitermite Knock-Out be used during flowering?

addendum: You definately CAN use Doktor Doom, up to a few days before harvest. it breaks down within 24 hours of application.

or get floramite. it's more expensive and doesn't break down for 2-3 weeks, so you have to plan when to use it during flowering.
 
its a long game and very boring but i boiled some water put it in a bowl and sprayed a few squirts of bayer gardens all in one into the water then physically washed each fan leaf with a spounge starting at the bottom working up to the top, after washing every leaf you can see all the little buggers in the bowl, this got rid off all the mites and alot of the eggs but not all.
Ive now got 30 lady bugs fighting over each other in there no signs since then so hopefully its worked
