Wasps and hornets build nests in a wide range of spots around a Castro Valley property — eaves, attic vents, ground burrows, dense shrubs — often going unnoticed until activity picks up. A mix of older wood-frame Victorian and mid-century homes and newer high-density construction, most without air conditioning given the mild climate.
Nest removal starts with locating every entry and exit point, since a nest treated from only one angle can leave insects able to relocate nearby. For destructive species we eliminate the colony on-site; for honeybees, we coordinate relocation to preserve the colony rather than destroying a beneficial pollinator population.
