What's eating my butt's bougainvillea?
Bougainvillea looper caterpillar
Signs: Inchworm caterpillars consume leaves rapidly, leaving bare stems; visible notching along leaf margins progressing to full defoliation.
Control: Apply Bt spray at first sign; hand-pick larvae; pyrethrin for severe outbreaks; inspect after warm rains.
Mealybugs
Signs: Cottony white clusters at stem joints and axils; excrete honeydew that triggers sooty mold; leaves turn yellow and drop.
Control: Alcohol swabs on isolated colonies; neem oil or insecticidal soap spray; systemic imidacloprid for severe cases.
Aphids
Signs: Soft-bodied insects on new growth; feeding weakens shoots and distorts flower bracts; honeydew coats lower surfaces.
Control: Strong water jets; insecticidal soap; natural predators such as ladybirds and lacewings.
Scale insects
Signs: Hard shells on woody stems; prolonged infestations cause stunted growth and yellowing; bark may crack.
Control: Horticultural oil at dormancy; scrub crawlers with insecticidal soap; remove heavily encrusted stems.

What is eating my butt's bougainvillea?
Butt's bougainvillea (a vigorous hybrid) is hit hardest by the bougainvillea looper caterpillar, which can strip foliage in days. Aphids, mealybugs, and scale are persistent in warm climates. Spider mites flare up indoors or during drought. Early monitoring after rains — when loopers hatch — prevents the worst defoliation.
