calliope: maybe? How can I identify potworm? I look around and 1 website says its length is ~1/4 inch, and the other says it can reach up to 1 inch. One thing that totally confuse me (and make me think if this is a larvae of flying bugs) is none of the pots has been out for >4 months, and placed in a very closed apartment on the second floor. I have never seen them until 2 weeks ago. So where would they come? I don't have any gnats currently (have that before and successfully eliminated with Gnatrol), but I have to admit that I got bites at night, not sure if it is related or just mosquitoes.

Monica, The main active ingredient in that product is imidacloprid which is a powerful toxic chemical. While it is quite effective at getting rid of many awful pests including spider mites and mealy bugs (my personal nemesis, the mealy) it also kills many beneficial insects like bees. It is also harmful to people and pets. I have used it in the past, and if faced with mealy bugs dripping off my plants I might resort to it again, but for now I have eliminated bayer from my own toolkit. Easy decision since NY State made it illegal first, and amazon won't even ship it to me. I would never ever consider spraying or using it indoors. I encourage you to do some research on imidacloprid to at least be well informed. If you eat the fruit from your citrus, make sure you know what you are doing. Daniel

It's more important that what nutrients are available are only those the plant needs for normal growth and available in a favorable ratio, than where the nutrients came from; plants cannot absorb anything in organic form. Also, a container medium's structure is it's most important asset, the second is how long it can retain that structure while in use. A medium's ability to provide nutrition for the plant should be very low on the list of things to focus on, this because it is monkey easy for the grower to institute and take absolute control over their plants' nutritional needs; and, there is nothing in worm castings a plant needs that it can't get from a good soluble synthetic fertilizer. Worm castings diminish a medium's singular most important asset - its structure. Al

Sorry, roseseek. What a dunderhead I am! I guess I was confusing this with the label directions and hadn't even read the above link! Wow! Thank you again. I applied it as directed and it has definitely helped. I still may spray some neem, but so far the drench seems to have eliminated everything. I just hope they didn't kill one of my cuttings. : (( Summers, just a warning not to use too much soap. I killed a couple of sensitive houseplants last year doing that. I guess the ratio was off.
