Blaptica dubia has become a popular feeder insect, particularly among tarantula, amphibian, and reptile enthusiasts and owners. Keeping or breeding the insect is made easier by their inability to jump or climb smooth surfaces, relatively slow movement, and rarity of flying. They are also quiet, unlike crickets, and tropical environmental requirements reduce the likelihood of establishment of escapees in colder, dryer climates. B. dubia can cause allergic reactions in humans, although they produce relatively little odor compared to many cockroaches.
