My sarracenia are suffering and I can't exactly figure out what is wrong. In some of them, when I unpot them, there are tiny black bugs in the soil that look like sugar ants. I thought that is what they were but as more and more sarracenia keep dying and I keep finding these bugs in the pots, I'm convinced they are what are killing my plants. I have thousands of sars, there's no way I can go through and repot every one of them, and even if I did, there's nothing to keep them from making nests in my plants again. So what I need is something safe for sarracenia that I can spray on them and totally saturate the soil with and everything that will kill these pests. What do you recommend and where can I get it in enough quantity to add to a sprayer and do all of my plants?
