Pest identification
What's eating my loofah?
Cucumber beetles (striped and spotted)
Signs: Leaf chewing and bacterial wilt vectoring; defoliation in heavy infestations
Control: Row cover until flowering; kaolin clay on foliage; remove infected wilting vines immediately
Aphids
Signs: Dense colonies on shoot tips and flower buds; honeydew and distorted growth
Control: Insecticidal soap spray; encourage parasitic wasps; aluminium-foil mulch repels alate aphids
Squash bugs (Anasa tristis)
Signs: Angular yellow-to-brown patches on leaves; sap-sucking causes vine wilting and reduced fruit set
Control: Destroy brown egg clusters on leaf undersides; hand-pick adults at dawn; neem oil; trap boards to collect overnight
Two-spotted spider mite (Tetranychus urticae)
Signs: Fine stippling and bronzing of leaves in hot, dry weather; fine webbing on undersides
Control: Mist leaves regularly to raise humidity; insecticidal soap or horticultural oil; introduce predatory mites (Phytoseiulus persimilis)

Loofah pests — FAQ
What is eating my loofah?
Loofah (Luffa aegyptiaca) is a warm-season cucurbit that attracts the same beetle and aphid complex as squash and cucumber. Cucumber beetles spread bacterial wilt and can kill vines before fruit sets. Spider mites thrive on plants in hot, dry conditions. Squash bugs feed on sap and stress the vine. Scout weekly once vines are established.
