Safer BioNeem or similar product are safe alternatives for insect control - I've used this successfully for the only spidermite attack I've had, which was caught early and was small-scale. It can be hard to completely eradicate the insects with biologically safe products.

The HotShot No Pest strip works really well by most accounts, I would use one of these before I used some other form of manually-applied chemical control. The HotShot has the advantage of continuously applying the insecticide, killing the larvae as they hatch, and eventually eradicating the insects. It is supposed to be relatively safe and breaks down rapidly, but who can say for sure what the long-term effects might be (the same holds for any form of chemical control IMO).

I've used predator insects outdoors, they only control the bad insect population and rarely eradicate them IMO. In the end, it all depends on what you're willing to live with and who is smoking the product; I personally wouldn't use chemical methods that weren't FDA-approved for food crops if I was supplying other people...

Good info, I personally don't want to resort to using chemical methods but this is my first grow so i'm not sure what to expect with these mites. i'm going with the strips. Do you know if I can use the strips and lady bugs at the same time or whould it kill them aswell?

I reckon it would kill just about any insect, including ladybugs. If I was going to use a HotShot, then depending where you're at in your grow - I wouldn't use the HotShot for at least the last two weeks of the grow - I would use it for about two weeks to make sure the adults and larvae were killed, then I would take it down and use ladybugs to help prevent recurrence (not sure if the ladybug's would survive or hang around with nothing to eat, though).

Sounds like a good plan, i'm on my 4th week of 12/12. I'm gonna go with what you said, going to use hot shot for 2 weeks see where i'm at with the mites then lady bug my plants to keep them at bay until it finishes off. thanks once again you really helped me out. peace

ive been batteling mites for the past ...i dunoo...10 years. Neem oil is ok as a treatment alone, but when you stop using it in flowering you will run into problems.

Any soap works to kill the adults. There are insecticidal soaps that contain only potassium salts and are barely, if at all harmfull to the plant, unlike some other sprays.

buddy mentioned using 50/50 Isopropanol and water during flowering cycle, seems good in concept although maybe a little rough, personally, when i need to stop using pyrethrum or neem(as i start flower) I switch to using 1% hydrogen peroxide to mist, to knock down adult populations before i introduce predator mites.

In a mite infested house, pyrethrum or neem or even soap in veg (if necessary) and hydrogen peroxide(or something similar) and predator mites has proven to be the best combination.

Commonly thought about predators is that they dont thrive in say a closet grow. But they do thrive in perfect conditions for your plant, so Disregard people saying closets ops wont support predators, because they can and they will provided the humidity and temp are at optimal levels for your plants.

Spidermites!!!!! there is a fda approved chemical got it at my nute store. But you also have to remove 2 inches of the dirt in each pot because they are ground hatched. the box was lite green and white can't think of the name of hand and don't have it around anymore. and to tell you the truth i never really sprayed my plants because it leads to trouble watering in the first of the light cycle is good for all plants. If your water sprayer had chlorine cause noboby let the water sit for 24 hours min. You just sprayed it all over your plants/buds.

i know, im pretty late to the party. but, my experience with leaves looking like that are rose slugs. there not true slugs. there larvae of fly species (many species in the world). the adults lay eggs between the leaf layers, and the larvae emerge to feed, leaving translucent streaks on the leaves. they then drop into the soil and pupate. i didnt want to use chems either. ladybugs eat aphids. larvae is an aphid (soft body insects). they work for me when i need them

peace
