Wasps adore sweets, particularly open soda and beverage bottles, red berries, candies, sauces, and confections, among similar items. Protein items like meat, yolks, and milk products are also attractive, so keep trash bins well-sealed and rid of cooking wastes carefully. Water supplies and particular scents also attract yellow jackets, hornets, and sheet nesting wasps. Enclosure workers will be drawn to swimming pools, recreational lakes, and other sources of moisture.
