Do Bees Need Water? Essential Hydration Tips for Beekeepers

One of nature’s most peculiar insects draws our attention to its way of life, but we wonder: Do bees need water?

Bees are insects that gather in hives or communities, which are led by a queen. Well, more than leading, it’s basically about feeding.

The availability of water and food for bees and hives is among the most important resources alongside nectar and pollen.

Therefore, they generally need water near the hive, preferably from streams or natural sources. When the ambient temperature rises outside the hive, the water-collecting bees are set in motion to seek water to prevent overheating.

However, water needs are different in summer and winter, and it is important to differentiate them in the various seasons. But without a doubt, to the question: Do bees need water? There is a clear answer.

Water, humidity, or condensation are not the same for bees.

Do bees need water? How they detect it.

There is a group of bees called scouts who are capable of detecting the presence of water through various mechanisms.

One way is by using their highly sensitive antennae, which can detect water molecules in the air and on surfaces.

They can also detect the relative humidity of the air through specialized receptors in their antennae.

Additionally, bees can detect the presence of water sources through sight. Water sources often reflect light differently than other objects in the environment, making them stand out to bees.

Once they find a water source, they can communicate its location to other bees through the waggle dance.

This dance provides information about the location of the water source, the distance, and the quality of the water, allowing the water-collecting bees to efficiently find and gather water.

Water-collecting bees make several trips a day to obtain water.

How Bees Collect Water

Having answered the question of whether bees need water, there is another very important doubt: how do they transport this vital liquid?

When a water-collecting bee finds a water source, it fills its stomach with the water and returns to the hive.

Once the water carrier arrives at the hive, the bees deposit the water into special cells, where it is used to cool the hive and dilute honey during the maturation process. Generally, bees collect water whenever they need it, rather than storing it.

In warm climates, water-collecting bees may gather large amounts of water to help keep the hive cool and prevent overheating.

Vital Functions of Water in the Bee Hive:

Hives have changing water needs, which depend on the relative humidity of the environment and the rate of moisture loss from the insects.

This loss can occur through the cuticle, the excretory system, or the respiratory system. Therefore, the demand for water becomes especially critical during high-temperature months, when a hive can consume many milliliters of water per day.

It is estimated that a hive needs approximately 1 liter of water per week during the summer.

Breeding in hives requires precise maintenance of temperature and humidity, maintaining around 34°C and 60% humidity.

At the peak of summer, when outside temperatures rise, ensuring thermal regulation is crucial, as the interior temperature can exceed 35°C.

How Bees Use Water in a Hive

Another answer completes the response to whether bees need water, as you can understand below.

Bees regulate the interior temperature by evaporating water inside the brood chamber, a process they perform by placing drops of water on the top of the cells.

The evaporation produces a cooling effect, similar to that of an earthenware jug, which also cools the wax combs, preventing them from softening and falling or sticking together due to excessive heat.

The need for water for bees is so evident that the foragers will fly as far as necessary, risking their lives.

Bees that do not find a nearby water source can fly long distances to get it, but this will come at the cost of honey consumption.

In terms of production, this is a strategic input, but it is also mandatory according to animal welfare laws, as beekeepers may face sanctions.

Therefore, beekeepers must understand that they need to provide water drinkers if there are no natural water sources.

Do Bees Need Water?: How They Use It to Process Honey

The processing of bee honey is a process that involves several steps, in which everyone in the hive participates.

Once the nectar is extracted from the flowers, the honey-making process continues when the bees ingest the nectar and store it in their abdomen, known as the “honey stomach.”

Once ingested, the bees modify the pH of the honey by combining it with enzymes. Subsequently, the bees return to the hive, where the honey-making process continues.

There, they pass the nectar to other younger worker bees, which extract and break down the nectar through various enzymatic digestions into simpler compounds, mainly rich in fructose and glucose.

This gives honey its sweet taste and high caloric content. The bees chew this nectar for about half an hour until the moisture of the nectar drops from 70% to 20%.

Additionally, these enzymes modify the pH of the honey, bringing it to around 3.9%, making it a very acidic product. Water is needed throughout this process.

What Happens If Bees Run Out of Water?

Here’s another answer to the question: Do bees need water? These would be the consequences for the hive:

The lack of water can cause the bees to become dehydrated, leading to a reduction in honey production and a decrease in the number of larvae that can be raised in the hive.

Bees use water to cool the hive on hot days. The lack of water can cause the hive to overheat and result in the death of the bees.

Bees need water to hydrate and produce food. The lack of water can weaken production and affect the strength and health of the colony.

Bees use water to maintain their hygiene and to clean the hive. The lack of water can reduce the bees’ ability to maintain good hygiene, which can increase the spread of diseases and reduce the colony’s immunity.
