Wasps begone

“How long do bees live?” Ruth asked me at work. It’s a good question. I replied, “Six weeks in summer and around five months in winter, while queens can live for two or three years.”

It was funny to hear Pat get asked the same question by a family of new beekeepers on Saturday. Though it’s late in the year for visitors, a curious crowd had gathered to find out more about the bees. “The workers live for six weeks in summer, but now they’re fattening up to live longer over winter,” said Pat, as Jochen, Emily and I hovered behind to listen. David had opened his green hive to give the new colony a quick inspection before winter.

An observant beginner pointed at workers on the side of the hive with raised abdomens. I could hear Emily explain about nasonov glands and releasing pheromones for other bees to find their way home. “Sort of like a homing signal,” said the beginner.

It was lovely to enjoy a beekeeping lesson at the apiary and to hear the ‘oohs’, ‘ahhs’ and gasps of beginners. With not much beekeeping doing, the winter months are a chance to enjoy the company of beekeepers.

Emily and I put the mouseguards on our four hives this week, with a few pins from Jonesy, and topped up the feeders. Our dry sugar experiment hadn’t worked out, so I took away the bags. Like children who realise they can no longer play with an unwanted toy, it was only then bees scrambled up to drag down spilled sugar.

Melissa’s clever bees had also built their own honeycomb cover for one of the holes in the crownboard.

Chamomile’s hive had more diarrhoea at the entrance. It is a worry but there is not much we can do to treat nosema. Emily has Thomas’s thymol recipe to make up at home, but I’d be happier to get this colony shook swarmed in spring.

The mild autumn has kept bees, and wasps, active for longer. The wasp problem seems to have sorted itself out with only one or two lingering around hives. As I told a beginner, I hoped the bees flying out and about could find forage to replace all that honey they were eating to sustain their unseasonal activities.

In fact, this autumn seems to have confused bees and beekeepers alike with some still opening hives for inspections. I asked Alan and John their views. Alan was firm this does more harm than good, “You’re letting out all that warmth and breaking up the propolis. Leave them alone.” When I said that some had even found queen cells in the hive, Alan just shook his head and shrugged: “They’re not going to mate now and there’s nothing you can do. Wait till spring and if you have a drone layer, then replace her.” Personally I agree. Sometimes we have to let nature alone and accept what will be.

Jochen puts his hand over a hole in the crownboard to feel the warmth that the bees generate inside the hive, probably around 30°C. 

Sitting at the table I remembered how much I enjoyed being an Ealing beekeeper. Perhaps one day when I keep bees away from the apiary I’ll be able to enjoy visiting just for tea and cake. Jonesy and Stan checked out the suspected wasp nest, confirming it was indeed a wasp nest. Stan even offered to remove it, but we all agreed that the wasps will die out soon. Better to give the wasp queen a chance to fly away first and find somewhere to hibernate till next year.

That done, the Ealing beekeepers cleared up tea cups and brushed off biscuit crumbs. It was time to leave the apiary gently humming in the warm autumn sun.

The wasp palace

IMG_5547

The afternoon had turned out perfectly nice for beekeeping. A low sun brought its warmth closer to the bees who were flying out and about like on a spring day. Mushrooms with long shadows had popped up all over the place to remind me it was autumn.

It was the second Saturday of the month which meant that Ealing beekeepers were at the scout hut for a workshop. But I was not the only visitor to the apiary, there were also the wasps. Last Sunday I had laid a couple of traps to deter wandering wasps from bothering our hives. Yesterday I found out it might not be so easy.

IMG_5576

This is as close as l’m going to get to a (suspected) wasps’ nest, even in a bee suit. A small burrow in the ground with fast-flying insects coming and going in a blur. Too small for bumbles and too many for solitaries. Had I stumbled on a wasp palace?

Wherever the wasps were hiding, the Wasp Queen had given orders to attack Queen Chamomile’s bees. As Emily arrived and stepped through the mushroom path, I had found a dent in the woodwork of Chamomile’s hive that hadn’t been there before. It seemed too early for woodpeckers who would still have lots of other tasty things to eat. “They don’t usually become a problem until the ground gets hard,” said Emily.

EDIT: wood damage from rot, woodpeckers or very determined wasps! Some helpful suggestions in the comments below.

Irritated by the wasps circling the hive boxes like sharks in the water, I looked at the front and saw a row of wasps scraping and gnawing at the wood, determined to get inside.

Luckily, Emily and I had some spare duct tape and together we taped around the vulnerable seams of wood between the hive boxes and the crownboard. The wasps weren’t happy and retreated back to their queen for new orders.

IMG_5580

There is nothing more tempting to a beekeeper on a sunny day than a wooden box full of insects. But we resisted the temptation to open the hives. The opportunity for wasps to fly in and stress the bees would be too great. Instead we cleaned and topped up feeders with syrup.

We also left small bags of dry sugar under the roofs of Melissa’s and Chamomile’s hives as an experiment. Emily had read that some beekeepers feed hives dry sugar in autumn and spring, leaving the bees to add the water themselves. Though all our colonies are heavy with winter stores, Melissa’s inquisitive workers immediately checked out the spilled sugar. We’ll see next week if they liked it or not, as it’s a useful tip to know if we’re ever caught short of syrup or fondant.

We then walked around the apiary to visit the other beekeepers’ hives. The new bees living in David’s old green hive seemed much better tempered and were content for us to watch them come and go. Although I spotted a hitchhiker on a returning forager (image above, bottom left).

Emily found a worker crawling beneath the apiary’s top bar hive with shrivelled wings, likely caused by deformed wing virus (DWV). Another clue that varroa was always lurking and that we must be ever vigilant against bee diseases even after a good season.

The wasps would probably finish off the hapless bee. They are, after all, useful scavengers. Incidentally, we should also thank wasps for beer and bread.

A new beekeeper had arrived not realising that everyone else was at the scout hut. He had recently got a colony of bees from John Chapple and was giddy with excitement. “I can’t stop watching them.”

John Chapple would tell us to leave the bees alone as, despite appearances being contrary with bees flying in and out with brightly coloured pollen, they were making preparations for winter. Preparations that would be undone by nosy beekeepers pulling at frames to say hello.

With that we closed the gate and left the bees, and the wasps and the mushrooms, to enjoy the rest of the afternoon in peace.

Autumn is coming

Last post Emily and I were in the thick of it. We had to abandon combining two hives as angry bees got the better of us.

So the following Tuesday evening we met at the apiary and pulled on bee suits over smart work dresses and heeled shoes. Emily was wearing a beekeeping jacket that left her legs perilously bare – but it was the mosquitoes, not the bees, who feasted.

Rose’s colony was more bad tempered than ever and, although we couldn’t find the queen, we were almost certain the colony was queenless. The bees have been trying to supercede Rose since spring and our artificial swarms only delayed their efforts to overthrow the reigning monarchy.

We laid a sheet of newspaper over the brood box of Chamomile’s colony and moved over Rose’s colony, then left the apiary hoping for the best. Emily revisited the following week and removed the newspaper, which was mostly chewed away by the bees. All seemed well. In the time the bees had eaten through the newspaper they had gotten used to each others’ smell and were one happy colony. This was also an indication that Rose had gone as the two colonies were more likely to fight if two queens had been present.

A Saturday went by as we shopped for wedding and bridesmaid dresses for Emily. Today was the second Saturday of the August and the apiary was lovely and peaceful as the association held its monthly scout hut meeting. However, we had both forgotten to bring a smoker and the noise of irritated bees soon filled the air.

Myrtle’s colony was well behaved and, as we’ve never smoked these bees, we were able to check both brood boxes and spot our shy queen. I’m rather proud of Myrtle. She is in her second year of being a queen and is still making nice, well-behaved bees.

Chili’s and Chamomile’s colonies were much feistier. They are the daughters of Rose, the queen of the colony we bought from Charles. We managed to check a few frames before they let us know that we should have brought a smoker. All seemed well inside the colonies though. We have three strong hives and apparently enough honey stores for winter. Myrtle, Chili and Chamomile are our autumn queens – an interesting blend of essential oils, I might try it!

At this time of year the bees start to prepare for winter. The queen lays less and the workers bring home propolis to insulate the hive. They are more protective of their honey and on guard for robber bees, wasps and other pests who might want to steal their precious stores. This can make them less tolerant of beekeepers too.

Emily spotted drones being pushed out of the entrance by workers and a few wasps were buzzing around the roofs and floors.

Autumn is coming.
