Pest identification
What's eating my red-fleshed dragon fruit?
Mealybugs (Pseudococcus spp.)
Signs: White waxy cottony masses in stem crevices and areoles; honeydew and sooty mould on the succulent stems; stunted growth and bud drop.
Control: Dab colonies with alcohol-soaked cotton swabs; apply neem oil or insecticidal soap; introduce Cryptolaemus montrouzieri (mealybug destroyer) in warm garden settings.
Scale insects (Diaspididae / Coccidae)
Signs: Hard or soft waxy bumps on green stems; yellow patches beneath scales; weakened stems and reduced vigour.
Control: Scrape off with a soft brush; apply horticultural oil to smother crawlers; repeat after 10–14 days to catch newly hatched nymphs.
Slugs and snails
Signs: Rasping damage to young succulent growth, emerging buds, and ripening fruit near the base of outdoor plants.
Control: Apply iron phosphate slug pellets (safe for wildlife and pets) around the base; hand-pick at night; elevate containers or use copper tape barriers.

Red-fleshed dragon fruit (Selenicereus costaricensis) is a cactus with few serious pest enemies. Mealybugs shelter in the areoles and stem crevices; scale insects colonise the thick stems; aphids attack tender new growth. Outdoors, slugs and snails rasp through young pads and emerging buds in humid conditions.
