My indoor grow chamber seems to have an aphid infestation. It is hard on my smaller sundews, and they seem to be making a home of the Utrics, as well.
One solution suggested to me a long time ago was to use pet flea collars. If I went this route, how many would I need to assure full coverage of the grow chamber? Or is this solution really only recommended for small, enclosed terraria?
What insecticide would you recommend, other than the flea collars?
