What is the natural predator of earwigs? Natural predators of earwigs include variety of animals that prey on them in garden and soil. Birds such as robins, chickens, and other insectivorous birds eat earwigs. Small mammals like shrews and mice prey on earwigs. Reptiles like lizards and geckos eat earwigs. Amphibians like toads, frogs, and salamanders eat earwigs in damp habitats. Spiders, especially ground spiders, prey on earwigs. Insects like ground beetles, assassin bugs, and tachinid flies are predators or parasitoids of earwigs. Centipedes also prey on earwigs. Parasitic flies and wasps lay eggs on earwigs. Domestic chickens are effective predators in gardens. So natural predators include birds, mammals, reptiles, amphibians, spiders, beetles, assassin bugs, centipedes, and parasitic flies and wasps, which help control earwig populations outdoors, though indoors they have fewer predators, which is why they may survive longer if moisture present.
