Wasps become noticeable when they interact with human environments. Understanding what draws them helps manage their presence. They are attracted to specific food sources, certain scents, visual cues, and suitable locations for water and nesting.
Sweet and Protein Sources
Wasps are primarily attracted to food sources that provide energy and nutrients for their colony. Adult wasps seek sugary substances for quick energy, while protein feeds their developing larvae. This dietary need shifts; early in the season, wasps hunt for protein, and later, their craving for sugar intensifies.
Sugary attractants include ripe or overripe fruits, especially fermenting ones. Sweet beverages like soda, juice, and alcoholic drinks are also appealing, as are picnic foods such as desserts and candies. For protein, wasps are drawn to meats, including hot dogs, burgers, deli meats, and pet food. Open garbage bins with food waste are significant attractants, offering both sugary and protein-rich scraps. Adult wasps bring these protein sources back to the nest for larvae.
Artificial Scents and Bright Colors
Beyond food, wasps are drawn to artificial scents and visual cues that mimic their natural environment. Sweet or floral scents in human products can imitate flower nectar. Perfumes, colognes, scented lotions, hairsprays, and some sunscreens can inadvertently attract wasps due to these fragrances. Avoiding such strong scents can reduce their attraction.
Visual cues also play a role. Bright colors, particularly yellow, white, and orange, resemble flowers where wasps might find nectar or prey. Floral patterns on clothing or outdoor decor can attract them. Bright attire can inadvertently make a person or an area more appealing to wasps.
Water and Nesting Opportunities
Wasps require access to water for hydration and nest construction. They use water or wet mud to create pulp for paper-like nests or to construct mud nests. Sources like bird baths, pet water bowls, leaky outdoor faucets, puddles, and damp soil provide accessible water. Wasps are observed hovering over water sources, collecting liquid.
For nesting, wasps seek sheltered, undisturbed locations that offer protection from elements and predators. Common sites include areas under eaves, in attics, sheds, garages, and wall voids. Dense shrubs, hollow trees, and abandoned burrows also serve as suitable environments. These locations provide a safe environment for wasps to build nests and raise young, often near human habitation due to food availability.
