Dan7- great idea, but when you have too many it is difficult. how I dealt with it was pulling all outside (porch) cleaning all the windows, shelves and groves with clorox, than, dunk each individual cup or pot, let it drip all excess and put them back in place with cups with soap and yellow fly traps everywhere. So, I think I am doing OK now, but my guards are in very high alert, for these creatures. They are tiny and evil.
The plants started to show life, wilted ones with new growth, so I may have lost less than I thought- only time will tell.
