Pest identification
What's eating my yellow pitcher plant?
Aphids
Signs: Dense colonies on new pitchers and phyllodia in early spring; distorted growth, honeydew, and reduced pitcher production.
Control: Wipe off by hand on young pitchers; use a strong water jet or very dilute insecticidal soap. Avoid horticultural oils, which can harm Sarracenia.
Exyra ridingsii (pitcher moth caterpillar)
Signs: Larvae bore into pitchers and consume the walls from inside; pitcher tops collapse and orange-brown frass collects at the base.
Control: Cut and dispose of infested pitchers immediately — do not leave cuttings nearby. Apply Bacillus thuringiensis (Bt) to remaining pitchers as a preventive spray.
Slugs and snails
Signs: Irregular holes chewed through fresh spring pitchers; worst on soft new growth, leaving a slime trail.
Control: Hand-pick at night; use iron-phosphate slug pellets (safe near bog plants) around the container. Avoid metaldehyde near water features.
Scale insects
Signs: Hard, flat brown bumps on rhizomes and pitcher bases; weakens the plant over successive seasons.
Control: Scrape off manually and treat with dilute neem oil applied with a cotton swab; avoid soaking pitcher interiors.
