I'm an organic grower and I have a whitefly infestation. What is the best way to control these monsters?

We still had whiteflies after using the organic solutions and daily baths!

Someone told me CO2, which we don't have. So, we got very large heavy duty lawn bags, and wrapped and ran car (specifically, Jeep) exhaust into them a few times for about 5 minutes each. Every day. Did not see any more.

Harvested them within a week (as scheduled), except for one needing longer hid outdoors "just in case". It did have a few back, but most migrated off. So then they got my gardenias and roses.

Hey, I found a pic of the one left outdoors. Infestation was much slower outdoors than on the indoor, plant turned out OK, 1 1/2 oz still:

Thats why you want to use no pest strips to catch the flyers to help catch the adults so they don't lay as many larvae and it minimizes the amount of eggs they lay by a lot.
That makes all the difference in controlling and not controlling them.

Thanks for the responses Stitch and Pat. I think the sticky traps and predators will be my choice. I forgot to say that I'm going into my 3rd week of flower, and most are showing flowers. Don't want to spray anything on them at this stage. What do you guys think of ladybugs or lacewings?

Stich, I was confused with no pest strip, but then understood it as the name of product is No Strip. LOL

I also have these white flies.

no pest strips and some neem oil and you got them killed :)

SAfer soap works well too.

safer soap is the best thing ive seen... strips never work for me. just look ugly hanging there.

Ya, don't spray anything on the flowers since your in 3rd week of flowering; use no pest strips; sticky traps work; but the no pest strips will work better.

lol ronly.

Car exhaust seems to keep the buggers dead. Doesn't harm the buds either, actually, they seem to "bask".

Because we also organic garden, we dumped all outdoor plants that the whitefly enjoys, and will not replant any for a year as advised by Dept. of Agriculture.

interesting on the car exhaust idea, would that work on mites or gnats also.

Ladybugs are a joke unless conditions are ideal.

Yes, it is killing the mites. And the buds seem to explode bigger each treatment. It won't kill the eggs, so retreatments are necessary until harvested, but its working so well right now, He is keeping a couple big branches from very last plant that had mites going still (camera is with Him, or I'd show you). Which I think is too much work and $ (1000k light) when I just jarred this morning the rest of the plant, and it was killer smoke! (and we haven't fertlized for 2 weeks before harvest). Had some dry winds and the stuff cured in a couple days. Miteless.

I haven't had gnats since started this idea, I think that other whitefly thread - CO2 solution came up in was about in November.

I had a bad infestation and mosquito dunks saved me. Add a inch of perlite to the surface to deter the flys returning.
 
If you have them bad, like I did then you have to hit them with all ya got.
1. Like stated, no pest strips, but this did not get them all for me.
2. Safers soap. Spray the hell out of the leaf tops, but you must spray the bottoms because that is where most are hanging out.
3. Vacuum, yes vacuum. Shake plant and have your vacuum ready to suck up the fliers. Do this twice a day, right before lights go off and on. White flys are very lazy at this time fly around much slower. You will be surprised how fun it is when u r good and stoned. If you have a huge garden, then it's no fun at all.
4. Yellow sticky traps. Leave them close to soil, hang them, place them where ever you can. Shake plant and they will be attracted to the color.
5. Repeat. 9 out of 10 times you will not get them all when you think you have and presto they hatch and away they go.
Good luck

I started out with K+Neem by Organica. It slowed them down, but didn't totally eradicate them. Next I'm going to use Zero Tolerance by Ed Rosenthal hoping that'll work a little better. The vacuum trick sounds good as well, but I can get careless at times. Wouldn't want to suck my plants up the hose :spank: It's interesting to shake the plants and watch them go straight to the yellow sticky trap. Throughout this thread nobody has mentioned predators. Does anybody use them?

I had good success with Encarsia formosa. Spinosad was also surprisingly effective.

:D
