The key to locating wasp nests is to not only be able to identify what a wasp nest looks like but to also watch movement patterns of the wasps. Wasp nests are most often found in roof eaves, garden sheds and behind shutters. Except for mud daubers, which use clay and mud to build their nests, most wasp nests are constructed of chewed wood.
There are different types of wasps that build unique nests. Paper wasps build open, exposed nests that resemble upturned umbrellas, and they can become quite aggressive and sting if they sense a threat. Yellow jacket and bald-faced wasps build a paper covering over their nests, and they can also become quite aggressive when it comes to protecting their nests. Mud daubers construct nests of mud or clay designed in a tubular shape.
Wasp nests grow in size throughout the summer, and they can reach considerable size by mid-summer, after queens have laid eggs and worker wasps have continued the building process. Occasionally, wasp nests can be found in attics or within the walls of a building or home. If this is the case, it is recommended to hire professional exterminators to rid the structure of the wasp nest. Not only do the nests become bigger as the season continues, but wasps can also become more aggressive and are more likely to sting as time goes on, so early removal is essential when a nest is found.
