Get yourself some dry ice if ya can and load up your grow room with it. If ya got an air conditioner turn it on in the room and let it get down to about 55 when the lights are off. It slows them down to a snails crawl and it don't hurt the plants, but gives nice purple nuggs.:thumbsup:

The idea is to cool off the room which makes them not want to bread so fast. And have seen them leave a room which is colder inside than out side.

If your into some kind of spray, Ed Rosenthal came out with a safe spidermite treatment. Ed Rosenthal's Zero Tolerance Natural Garden Solutions
