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.
To kill dirt daubers around your home, it's important to find the nest, which is usually in a high place. Once it is located, use a ladder to climb up to the nest and spray it with wasp killer spray. You should burn the nest once all the wasps are dead. The nest is a tube-like structure made of mud, which these wasps build.
