Having a home infested with spiders is a nightmare. I notice lots of wasps in the garden, I am learning wasps are my best form of spider control. One wasp I love is the Mud dauber (Dirt dauber) wasp. These efficient spider killers make mud cells to reproduce, these mud cells are loaded with multiple spiders for the Mud Dauber lava to feed on. I have captured video of a wasp filling a mud cell, this time I will investigate the spiders I find inside 2 mud cells. Mud daubers are fairly docile and dont attempt to sting humans unless directly threatened. Possibly the most awesome wasp is the Spider wasp, there is a sneak peek of a video I will upload soon. \r

Mud dauber (sometimes called dirt dauber, dirt digger, dirt dobber, dirt diver, or mud wasp) is a name commonly applied to a number of wasps from either the family Sphecidae or Crabronidae that build their nests from mud. Mud daubers, as they belong to different families, are variable in appearance, but most resemble long, slender wasps about 1-inch (25 mm) in length;. The name refers to the nests that are made by the female wasps, which consist of mud molded into place by the wasps mandibles. Mud daubers are not aggressive and stings are very uncommon.\r

Like most other wasps, mud daubers are predators. The females not only build the nests, but also they hunt to provision them. However, pipe-organ mud dauber males have reportedly brought spiders to the nest, and they aid in nest guarding.\r

Black and yellow mud daubers primarily prey on relatively small, colorful spiders, such as crab spiders (and related groups), orb weavers and some jumping spiders. They usually find them in and around vegetation. Blue mud daubers are the main predator of the black and brown widow spiders.\r

Adults of both es frequently drink flower nectar, but they stock their nests with spiders, which serve as food for their offspring. Like connoisseurs, they prefer particular kinds of spiders, and particular sizes of spiders for their larders. Instead of stocking a nest cell with one or two large spiders, mud daubers cram as many as two dozen small spiders into a nest cell. They appear to know exly what they are hunting for, and where to find it.\r

To capture a spider, the wasp grabs it and stings it. The venom from the sting does not kill the spider, but paralyzes and preserves it so it can be transported and stored in the nest cell until consumed by the larva. A mud dauber usually lays its egg on the prey item and then seals it into the nest cell with a mud cap. It then builds another cell or nest. \r
