Paper wasps are slender, elongated wasps known for their papery nests constructed from wood fibers and saliva. They typically build their nests in protected locations such as eaves, porch ceilings, and tree branches. Paper wasps are generally considered beneficial as they prey on pest insects such as caterpillars and spiders. However, they can become aggressive when their nests are disturbed, stinging multiple times to defend their colony. Paper wasp stings can cause localized pain, swelling, and redness, with the potential for allergic reactions in sensitive individuals.
