What are the two main criteria generally required for a successful wasp nest location?

Protection from direct precipitation and minimal vibration or physical disturbance

While species preference dictates the general area, the overarching requirements for successful colony establishment, regardless of whether the nest is aerial, structural, or subterranean, center on physical security and environmental consistency. Protection from direct precipitation is vital to prevent the structural degradation of the nest material, whether it is paper pulp or mud. Equally crucial is minimal physical disturbance; constant vibrations, accidental bumping, or proximity to high-traffic areas can jeopardize the integrity of the structure and stress the developing brood. Areas like deep brush piles or seldom-used woodpiles meet these security demands perfectly.
