Beekeeping In March
Excerpted from: Winterizing Bee Hives
March is a month where your bees can do great or they can do terrible. The bee population is expanding
exponentially and the bees are consuming more food.
Weather during March is a mix between winter and spring. Though the weather may be volatile, the bees
are charging full speed ahead towards spring.
The queen is laying an enormous amount of eggs now. That brood requires a lot of honey and pollen to
fully develop. The bees being laid now will hatch out into adult bees in 3 weeks. The increase in population
can mean 2 things:
1. The hive can starve before the main nectar flow starts, or
2. The bees feel crowded and decide to swarm.
When a significant amount of brood is being laid, which happens from mid-February through May,
bees are on a constant search for water and pollen; both are required to raise healthy brood. You may
see your bees sucking the moisture from potted plants or puddles, pulling trace minerals in the “dirty”
water up as they suck up the water.
With all these new bees hatching out, you will see more activity in the front of the hive. You will see the
most activity around 1 or 2 in the afternoon. This is when the new bees will take their orientation flights.
Orientation flights are when the young bees fly outside the hive, visually mapping their surroundings.
March is the month where starvation is at its highest possibility — the only food available is honey
reserves left from the previous year.
This time of the year, varroa, wax moths and small hive beetle populations are low. But you should think
about strategy beforehand. If you are planning hive fumigation — decide what device you will
You should time oxalic acid treatments for Varroa mites for when there is little brood in the beehive.
You can also kill off brood during treatments and return the brood frames after you have cleared mites
from the hive. If your bee colony gets heavily infested during spring or summer, it is permissible to treat
using oxalic acid so that the colony is not overwhelmed by Varroa mites.
Oxalic acid vaporization in beehives is an effective Varroa mite control method. Indeed, it kills mites that
are crawling around the hive, on bees and in uncapped cells. Vaporization utilizes portable gear that you
position inside the beehive. The acid vapor spreads out into the entire beehive. You must wear safety
gear at all times when using oxalic acid.
Fogging with oxalic acid is a very effective method of Varroa mite control. It has an effectiveness rate
of up to 99% on every treatment when done properly. Beekeepers should keep in mind however, that
fogging with oxalic acid does not harm the mites that are still in honey bee brood cells. Repeat treatments
up to 4 times depending on the interval to completely eradicate Varroa mites from your apiary.
Brood nest temperature is of extreme importance to the colony and is controlled with utmost precision.
Honey bees maintain the temperature of the brood nest between 90°F and optimally 95°F so that the brood
develops normally. When the temperature in the nest is too high the bees ventilate by fanning the hot air
out of the nest or use evaporative cooling mechanisms.
There are a number of commercially available in-hive temperature sensors to monitor the temperature,
humidity and C02 levels inside your hive.
As your bees are expanding, many beekeepers will rotate boxes in hopes of stemming the bees
desire to swarm. This is done by simply moving the bottom box to the top of the stack, preferably
done just before a warm spell.
Many beekeepers will feed their bees sugar syrup or pollen patties in the spring, but this may not be necessary
unless the bees are at risk of starving. It may be necessary if the beekeeper wants the bees to build
in population very quickly. Be warned, though feeding bees syrup and pollen in the spring can cause
them to swarm very quickly.
By using the bees' natural instinct to grow and expand during the spring, a beekeeper can make splits
or nucleus hives from their bees. This is the perfect time of the year to do this, as there will be a lot of
drones in the air for queens to mate with. It can be very easy to do, especially when using the walk
away split method.
An optimistic beekeeper can set out swarm traps in the area to catch swarms. A swarm trap will not
entice an established hive to leave their hive but will encourage a “homeless” swarm of bees to
move into your trap. Lemongrass lure is a simple way to increase your odds of catching one.
Many beekeepers use pollen patties to help their bees. They often cause to build up their population
very quickly. Feeding bees is helpful for some beekeepers, but they can cause swarms.
Use pollen patties very conservatively — more is not better with pollen patties.
