Wasp and hornet removal for San Francisco, one of the mildest climates in the state for a colony to survive winter and grow into something oversized.
Call (844) 924-1337Western yellowjacket colonies normally die off after a single season, but California's mild winters occasionally let an old queen overwinter successfully, and few places in the state hold a narrower, milder year round temperature range than fog cooled San Francisco. When that overwintering happens, the colony that follows can grow into what pest professionals call a perennial nest, sometimes holding tens of thousands of workers instead of the few thousand a normal annual colony reaches.
A perennial colony behaves more aggressively and in far greater numbers than the paper wasp nests typically found under eaves and balconies across the city, so treating every nest the same way isn't a safe assumption here. An unusually large or long established nest is worth having identified before anyone gets close to it.

It depends on the species and where the nest is located, but generally involves treating the nest directly with the right product and protective equipment, then removing it once activity has stopped. Because stinging insects can react defensively, this is usually safer left to a professional, especially for larger or hard-to-reach nests.
Most wasp colonies die off over winter, and an old nest is typically abandoned by the workers that built it. An empty-looking nest may still require assessment; if activity is uncertain, keep your distance and ask about inspection before disturbing it.
Paper wasp nests are often smaller and more exposed, commonly found under eaves or overhangs, but they can still sting if disturbed. Treating the nest directly and removing it once activity stops is the general approach, ideally handled by someone with proper protective equipment.
Locating the nest is the first step, since treating individual wasps without addressing the nest usually just means more show up. Species identification and nest location help determine the appropriate removal approach; avoid disturbing an active nest.
