Good morning, I'm relatively new to keeping houseplants again as I could just not keep them alive so recently I started again but did my homework. The issue is I've had persistent black fly for the past month or so. I've tried fairy liquid mixed in water and sprayed on the plants, I've tried gravel to prevent them laying eggs, restricting water to remove the dampness so any eggs will dry out and die, I've tried garlic infused water and shop bought black fly spray. I've also got up sticky catchers but they still persist. What else can I try? Any help or advice would be greatly appreciated.
James
