What's eating my utricularia sandersonii?
Fungus gnats (Bradysia spp.)
Signs: Larvae tunnel through the fine root system and wet growing medium, stunting growth and causing wilting
Control: Use yellow sticky traps for adults; drench medium with Bacillus thuringiensis var. israelensis (Bti) or beneficial nematodes (Steinernema feltiae); avoid over-watering trays that stay stagnant
Aphids
Signs: Cluster on delicate flower scapes, distorting blooms and leaving sticky honeydew residue
Control: Dislodge with a gentle water spray; dab with a cotton swab lightly moistened with 70% isopropyl alcohol; avoid systemic insecticides — they can be phytotoxic on carnivores

What is eating my utricularia sandersonii?
Utricularia sandersonii is a tiny terrestrial carnivorous plant grown in humid, boggy conditions. Its main threats are fungus gnats whose larvae damage shallow roots in wet media, and aphids occasionally colonising flowers. Because it traps micro-prey, chemical insecticides can disrupt its prey base and harm the plant — physical and biological controls are safer.
