Pest identification
What's eating my orange lily?
Scarlet lily beetle (Lilioceris lilii)
Signs: Bright-red adults and frass-covered larvae devour leaves, stems, and buds — plants can be fully stripped without intervention
Control: Hand-pick beetles and larvae daily into soapy water; spray with pyrethrin or neem oil; apply biological control nematodes around soil
Lily aphids (Macrosiphum lilii)
Signs: Sap-sucking colonies on leaf undersides vector mosaic virus, causing yellow mottling, distorted leaves, and poor flowering
Control: Insecticidal soap or neem oil spray; strong water jet to dislodge colonies; introduce or attract ladybirds and lacewings
Deer
Signs: Bite off emerging shoots and flower buds cleanly at night, sometimes removing the entire stem top
Control: Scent-based deer repellents applied weekly; temporary wire mesh exclusion during key growing months
