The sight of bees circling or landing on a swimming pool edge is a common summertime annoyance. This behavior is often misinterpreted as an attack or simple attraction to the water itself. Bees are diligently foraging for specific resources necessary for colony survival, not seeking to interact with people. Understanding this biological drive is the first step toward finding a non-harmful and effective solution.
Why Bees Need Pool Water
Honeybees have a profound need for water, especially during warmer months when hive activity peaks. A single, active colony can consume up to a gallon of water daily during the height of summer. This water is collected by specialized “water carrier” bees and serves two primary biological functions within the hive.
The first function is thermoregulation, which cools the colony on hot days. Worker bees spread the collected water across the comb inside the hive. Other bees then fan their wings to increase airflow, creating evaporative cooling. This process acts like a natural air conditioning system, protecting the brood chamber from overheating.
The second major draw is the mineral and salt content found in pool water. Bees actively seek out water sources containing concentrated minerals to supplement their diet. The slightly salty or chlorinated water of a pool is often more attractive than clean water because the dissolved solids provide necessary nutrients. Pool water, especially from a saltwater system, provides a readily available source of sodium and other trace elements.
Are They Bees or Wasps?
Before attempting any deterrence, correctly identify the insects visiting the pool, as their motivations differ significantly. Honey bees are typically rounder and covered with fuzzy, feather-like hair, which helps them collect pollen. When at the pool, their behavior is docile; they focus on drinking and rarely sting unless swatted or stepped on.
Wasps, such as yellow jackets and paper wasps, are generally smoother, with a distinct, narrow waist and slender bodies. These insects are predators and scavengers, making them more aggressive. They are interested in human food and sugary drinks left near the pool, in addition to water. Unlike honey bees, wasps can sting multiple times and are easily provoked.
Practical Solutions for Bee Deterrence
The most effective and humane method for managing bees near a pool is to provide a more appealing water source elsewhere. Setting up an alternative water station draws the bees away from the swimming area without harming them. This station should be a shallow dish or bowl placed far from the pool. It must contain rocks, corks, or sponges that serve as safe landing pads for the bees.
Bees often prefer slightly “murky” or concentrated water. Adding a small pinch of salt or leaving the water for a few days can make the station more attractive than the clean pool. Once the bees establish a flight path to this new source, they display site fidelity and will continue returning to the preferred location.
Natural scent deterrents can also be deployed around the pool perimeter to discourage bees from approaching the main water. Bees have an aversion to strong odors from certain essential oils and plants. Placing cotton balls soaked in peppermint oil or planting herbs like mint, basil, or citronella near the pool edge can help create a fragrant barrier.
Changing the accessibility of the pool water is another useful strategy. Since bees struggle to land on moving water, adding a fountain or pool jets to create surface agitation makes the pool less desirable. Covering the pool when not in use removes the water source entirely, forcing foraging bees to seek out the established alternative water station.
