One of several cactus species that is attacked by the cactus moth, Cactoblastis cactorum, which arrived in Florida in 1989, and this invasive species has become a serious threat to the diversity and abundance of Opuntia cacti in North America. If it becomes a problem on an Opuntia used in landscaping, it is best treated by manual removal as insecticides can also kill native butterflies and pollinators.
