Are mud daubers carnivores

In a Word: "no." Several species of wasps are referred to as mud daubers. Most belong to the family Sphecidae. These wasps are solitary wasps that hunt Spiders and other insects as prey. Their venom has evolved to act as a paralyzing agent for their prey. This is unlike social wasps, that live in a colonial nest. These wasps have evolved a painful venom, usually high in histimines, to deter intruders from disrupting their nest.
