Yes. In the countries where wasps originate, a wide range of natural predators have been recorded including invertebrates (dragonflies, robber flies, hornets, centipedes, and spiders), birds (at least 24 species are known to eat wasps, including blackbirds, magpies, starlings) and mammals. In Britain, badgers are the chief predator: they destroy entire colonies to obtain the brood-filled comb. Stoats, weasels and mice also disrupt colonies in the early stages. However, in New Zealand, one reason wasps have so successfully established is that most of their natural predators are not present
