Spotting a wasp’s nest taking shape under your eaves or in a corner of the garden can raise a lot of questions. What is it actually made from? How did it get that shape so fast? And why does it seem to grow bigger every time you check on it? The answer comes down to some surprisingly skilled teamwork, starting with a single queen and a mouthful of chewed wood.
In this guide, we're focusing on paper nest builders, wasps like yellowjackets, hornets, and paper wasps, since these are the species that most commonly cause issues for homes and businesses. Other wasps, like solitary wasps, build very different types of nests, often out of mud or by burrowing into soil, but they're much less likely to cause the kind of nest problems we're covering here.
Wasp nests are made from wood pulp. Worker wasps gather this material from sources like fence panels, garden furniture, dead tree branches, and even the frames of your home. Once collected, the wood fiber is chewed and mixed with saliva to create a paste. This paper-like material is lightweight but provides a great structure and insulation to protect a growing colony from the weather.
Building a nest is a careful, repeatable process. Here's how it comes together:
Most social wasps, including yellow jackets, hornets, and paper wasps, follow this same basic process. If you'd like to know more about how nest shapes and structures differ between species, our guide to types of wasp nests breaks this down further.

The process starts each spring, when a queen wasp emerges from hibernation and begins building a nest alone. At first, it's just a small, golf ball-sized structure with a few cells to raise her first workers. Once those workers hatch, they take over construction and foraging, and the queen focuses on laying eggs.
From there, the colony can grow quickly. By late August, a mature nest may contain around 20–50 paper wasps, 100–400 bald-faced hornets, 200–400 European hornets, or 1,000–5,000 yellowjackets. Some nests can also reach the size of a football or larger.
If you’ve spotted a wasp’s nest, don’t try to remove it yourself, as this can be very dangerous. Our wasp nest removal experts will handle it for you.
Wasps look for sheltered spots that offer protection from wind and rain while staying close to food sources. Common nesting locations include:
Checking these areas regularly, especially in spring, can help you catch a new nest while it's still small and easier to manage.
If you've noticed a nest forming on your property, don't disturb it. Even a small nest can trigger an aggressive response from the wasps defending it, and stings can be a serious concern for anyone with allergies. If you're stung and experience symptoms beyond mild swelling, seek medical attention.
Our wasp control services can help you address a developing nest safely before it becomes a bigger problem.
A queen can build a small starter nest within a few days, but the colony continues expanding throughout spring and summer as more workers join in. Growth tends to slow down again in early fall as the colony's focus shifts away from expansion.
No. Wasp colonies typically only last one season, and nests are rarely reused the following year. Once the colony dies off in late fall or winter, the old nest is usually abandoned for good, so a nest you spot in spring is almost always a brand new one.
Sealing cracks and gaps around your home, securing garbage, and checking sheltered areas in early spring can help make your property less appealing to nest-building wasps. If you find a nest forming, our wasp nest removal team can help you deal with it safely.
