Pest identification
What's eating my sarracenia purpurea subsp. venosa?
Aphids
Signs: Dense colonies on emerging pitchers and phyllodia in spring; distorted, stunted pitcher development and sticky honeydew
Control: Spray off with a strong jet of water; remove by hand; isopropyl alcohol on a cotton swab works on clusters — avoid broad-spectrum insecticides
Slugs and snails
Signs: Ragged holes chewed in pitcher walls and young growth, especially after rain; worst damage to new pitchers in spring
Control: Hand-pick at night; use copper tape barriers around pots; wool pellet mulch around pot rims deters slugs without harming the plant
Scale insects
Signs: Flat brown oval discs on pitcher stems and at the base of the rosette; sticky honeydew and sooty mould follow
Control: Scrape off with a soft brush; treat with a cotton swab dipped in 70% isopropyl alcohol; repeat every 10 days until clear
Caterpillars (moth larvae)
Signs: Large ragged holes in pitcher walls or leaves eaten down to the rhizome; visible frass signals the culprit
Control: Hand-pick larvae; inspect regularly at dusk; BTi spray (Bacillus thuringiensis) is effective and safe for Sarracenia

What is eating my sarracenia purpurea subsp. venosa?
Sarracenia purpurea subsp. venosa is an outdoor bog plant susceptible to aphids clustering on new pitchers, slug and snail damage to young growth, scale insects on stems, and moth caterpillars chewing pitcher walls. The pitchers trap insects but cannot protect the plant's exterior surfaces. Hand-pick pests; avoid chemical sprays which harm these sensitive plants.
