Pest identification
What's eating my eastern prickly pear?
Cochineal scale (Dactylopius spp.)
Signs: White powdery deposits on pad surfaces; red liquid when insects are crushed; pad yellowing and drop.
Control: Wash off with a strong hose jet; apply neem oil spray; remove severely infested pads and dispose of them.
Aphids
Signs: Soft green or black insects clustered at new growth; sticky honeydew attracts ants and promotes mold.
Control: Spray with water to dislodge; apply insecticidal soap solution; encourage predatory insects like ladybugs.
Deer and rabbits
Signs: Pads browsed or removed; clean cuts on pad margins or entire young pads eaten overnight.
Control: Fencing is the most reliable deterrent; motion-activated sprinklers or deer-repellent sprays can reduce browsing.
Slugs and snails
Signs: Ragged chewing on lower pad margins and new growth, worst in humid or rainy periods.
Control: Apply iron phosphate bait around plants; reduce mulch near the base; hand-pick at night if populations are low.
