As the warm months roll in across Southern California, so does the rise in stinging pests—and two of the most aggressive culprits making their way into your backyard are paper wasps and yellowjackets. While both species can be beneficial pollinators, they’re far from welcome guests when they begin nesting near your home, swarming your outdoor gatherings, or stinging pets and family members.
If you’ve noticed more buzzing activity around your eaves, patio furniture, or even underground burrows in your lawn, you may be facing a growing wasp problem. Here’s what you need to know about these stinging insects, the dangers they pose, and when it’s time to call in pest control services.
A Guide To Stinging Pests
Paper Wasps vs. Yellowjackets: What’s the Difference?
Though they may seem similar at first glance, paper wasps and yellowjackets differ in behavior and nesting habits:
- Paper Wasps are slender, with long legs and brownish-black coloring with yellow markings. They build their nests in exposed areas, such as under roof eaves, porch ceilings, and light fixtures. Their umbrella-shaped nests are made from chewed wood pulp that resembles paper—hence the name.
- Yellowjackets, on the other hand, are stockier and more brightly colored with sharp black and yellow stripes. These wasps are known for their aggression, especially when defending their nests, which are often hidden underground, in wall voids, or inside hollow logs.
Both species can sting repeatedly, making them especially dangerous to individuals who are allergic to insect venom. But even without allergies, multiple stings from an angry swarm can cause serious harm.
Why Are Stinging Pests on the Rise?
Several factors are contributing to the uptick in stinging pests throughout Southern California:
- Longer warm seasons mean extended breeding and nesting periods.
- Urban landscaping—like flowering plants, gardens, and fruit trees—provides abundant food sources.
- Human activity (like outdoor grilling, sugary drinks, and trash) attracts yellowjackets in particular.
Unfortunately, even if you maintain a clean yard, a nearby nest can easily turn your peaceful outdoor space into hostile territory.
Signs You Have a Wasp or Yellowjacket Problem
If you notice any of the following signs, it’s time to consider professional pest control services:
- Frequent sightings of wasps flying in and out of a particular area (e.g., eaves, bushes, or underground holes).
- Visible nests under overhangs or in wall voids.
- Increased wasp activity around food, trash cans, or hummingbird feeders.
- Buzzing sounds coming from within walls or ceilings.
Trying to remove a nest yourself can be extremely dangerous. Wasps and yellowjackets defend their colonies aggressively and may swarm if threatened.
