Yesterday I used this recipie to douse all the S/H plants which were showing teeny tiny silvery bugs swiming on the surface when I watered them.

I watered first (holding until roots I could see on top were green), then watered with the solution and waited until the buggies stopped swimming

(holding holes again), then put a bit more clean water on the top to flush out the bodies, then let drain and watered through intil I figured all soapy media was washed out. I suspect that they may be mealybugs, since I have been seeing more and more of these on my plants (in onesies and twosies and cleaning each time, but still getting more) but I don't really care who they are, as long as they go away. I have also soaked some of the plants in bark approximately the same way (using cottage cheese containers and bowls to hold the water level up). I check my plants every few days, so will let you know if the pests are gone next time I water.

With all the information in this thread, and the number of times I have used it, I would like to vote that it be made a sticky so people can find it up at the top.... Please?
