A number of swarming bees have been sighted in recent weeks.
On Tuesday a large swarm was spotted at Mandurah Forum near the Post Office, the most recent in a number of reports starting around September.
President of the Western Australian Apiarists Society Ian Beeson said this kind of behaviour is normal for bees at this time of year.
“Spring time is usually when they nest,” he said.
“They’ve been in over the winter months, usually it’s overcrowded now, and with everything happening and the warmth and that, usually they’re laying.
“Then the queen takes half the hive and swarms away to make a new one.”
He said they could stop anywhere to rest up, and will “ball” for protection, until the scout bees find a new home for them to settle.
Many people notice these “balls” on their cars and in other exposed areas.
“They’ll be in a spot for two or three days, and then they’ll move on,” Mr Beeson said.
“Other times if it’s suitable and protected they might start making a nest there, but usually they like to make it somewhere were it’s sheltered and closed in, not out in the open.”
He said when bees are swarming they are usually less prone to sting, as they are gorged with honey, and advised that people simply walk away steadily.
If a ball or hive needs to be removed, there are specialists available to relocate them humanely (which is important, as bees play an important role as pollinators).
