Well, lets try this approach and see if you understand my intentions.

About 3 years ago, I had a very bad infestation. So bad in fact that the entire top of one plant became an infested web .... overnight. As I have stated in other posts, the mites are an environmental natural phenomenon, and they are most prolific in temps 70-80 or so....at least here.

So, that is a bad infestation. All my plants were effected, flower and veg rooms. But only the one plant was horrific. Needless to say, that one plant was killed. Everything else got removed from the room, (which is in the garage, so it kinda is a 'loose' area, over completely indoors). I used a couple bug bomb things. Then I washed all the walls and floor with a bleach containing mixture. Each plant was heavily sprayed with Neem on the bottom of the leaves, around the stalk, and the top of the soil. The smaller plants got dipped in a Neem solution. The intakes, cracks, corners, etc., were sprayed with Sevin.

During the course of the next 2 weeks, I was able to hold off on harvesting until the mites were all gone.

Now, I just use Sevin monthly in the winter and weekly in the summer at the openings to the room, around the floor, all the corners and cracks. Again I cannot impress enough that cleanliness also has a significant importance on this. Last summer was the worst I have seen the mites here since I moved here, killing neighbors shrubs even, but I did not have any issues.

If you don't get them all, you will always have them. Remember, pyrethrins kill the adults, Neem kills the new babies and stops the process.
WashougalWonder Reviewed by WashougalWonder on . Pyrethrin and Neem during flower... how late in? Pyrethrins and Neem oil... how late can you apply them. I've heard that you must stop neem oil at the 3rd week of flowering. So, I'm guessing as soon as you start getting buds/calyxes you should not spray? I had pistils in day 1-2 of flowering on many plants, they are just starting week 3 and I see alot of pistils, but not any calyxes and buds forming yet... soon I'm sure! Can you still spray neem on the lower fan leaves of the plant throughout flowering? That seems to be where spider Rating: 5
