The presence of buzzing insects around a swimming pool is a common summertime issue. These insects, often bees, wasps, or yellow jackets, are drawn to the water for hydration, a biological function essential for their survival. Finding a safe and effective method to discourage them from using your pool as a water source is key to enjoying your outdoor space. The goal is to establish alternative, more appealing sources of hydration and make the pool environment less inviting without harming beneficial pollinators.
Identifying the Attractant and the Insect
Insects are primarily drawn to swimming pools because they need water for hydration and colony maintenance, especially during hot, dry weather. Honeybees collect water to regulate hive temperature through evaporative cooling and to dilute stored honey for feeding larvae. The pool’s size and stable nature make it an easily accessible and reliable water source.
Bees are often attracted to minerals in pool water, sometimes preferring chlorinated or saline water over clean sources. They may seek out specific concentrations of sodium and magnesium present in treated pool water. Once a bee finds a source, it exhibits site fidelity, returning repeatedly and marking the spot for others. It is important to distinguish between fuzzy, gentle honeybees and smooth, aggressive yellow jackets, which are a type of wasp. Yellow jackets seek protein and sugars in addition to water, making exposed food and drinks around the pool a major attractant.
Effective Diversion Strategies
The most sustainable solution is to offer an alternative water source that is more appealing and closer to their flight path. Establishing a dedicated bee watering station redirects foraging efforts away from the pool. This alternative source should be set up at least 20 to 30 feet away from the pool area to create clear separation.
A bee-friendly station can be a shallow dish, plant saucer, or birdbath filled with water. Crucially, provide safe landing spots within the water to prevent drowning, such as pebbles, marbles, corks, or wet sand. Set up this new source early in the season before insects establish a water collection routine at the pool. Maintain the water level consistently, as bees will return to the pool if their preferred source dries up.
Direct Poolside Deterrents
While diversion is effective, methods applied directly to the pool area can make the environment less desirable for insects. Physical barriers, such as a pool cover, should be used when the pool is not in use, removing access to the water surface. Breaking up the water’s surface tension also helps, as bees avoid landing on turbulent water; running jets or using floating toys creates this movement.
Sensory deterrents rely on strong odors that bees and wasps dislike, which can be applied to the surrounding deck and furniture. Essential oils can be mixed with water and sprayed around the perimeter, such as:
- Peppermint
- Spearmint
- Eucalyptus
- Citronella
Distilled white vinegar is another effective repellent that can be used in a 50/50 mix with water to wipe down railings and deck surfaces. These scent-based methods require frequent reapplication, often daily or after heavy rain, to maintain effectiveness.
Addressing Localized Nests and Professional Intervention
If a large volume of insects persists, it may indicate a nearby nest requiring a targeted approach. Determine the nest’s general location by observing the flight path of returning insects. A large, established nest, especially one causing aggressive behavior or located within a wall void, is too risky for DIY removal.
For honeybees, the most responsible action is to contact a local beekeeper or specialist who can safely relocate the colony without chemicals. Yellow jackets and other aggressive wasps, which often build paper nests in the ground or hidden cavities, should be addressed by a professional pest control service. A professional assessment ensures safety and proper species-specific removal, minimizing the risk of stings.
