June

This time of year used to be called the June gap and it all depends on where your bees have access to forage and the weather conditions.
It is always important to check that your colony has enough stores.
If the weather is poor and forage limited a large colony will get through its stores quickly.

Varroa management is important to, as a large colony will have an increase in mites.
Remember varroa mites cause stress to the bees and they provide a vector for viruses such as deformed wing virus.
Carry out a varroa mite drop and calculate the number you may have in your colony. The NBU has the calculator on its website.
Treatments in the summer can be something like MAQS or a pyrethroid if you have not used one in the last 5 years.
Keeping varroa mite numbers down at this time of year will help ensure winter bees are in top condition, with no viruses.

Hopefully the weather is warm and the bees are working well.
The colonies that have not swarmed will be preparing for the nectar flow next month.
If there is a good nectar flow it will be a good time to change frames of old comb in the brood nest as the bees will have the energy to draw wax.

Bees can still swarm in June so weekly inspections are still important.
