When Marc Newman’s wife brought a new bee hotel home from a local iron trade, he knew it would attract problems.
The 86-year-old had spent almost 20 years building the wooden structures that help support native bee numbers in the Darling Downs of Queensland and knew the specific specifications they needed.
The Toowoomba Local said, just like a lot of cheap imports, the Bijenhotel bought in the store failed.
He had to drill larger holes to protect native bees against predators such as wasps and also part of the wood that he suspected had been treated or replaced with toxic chemicals.

Mr. Newman said it was disappointing that unsuitable hotels were still sold.
“What happens is that the bees do not use hotels and people are disillusioned,” he said.
“It’s always on the internet, people have bought the hotel and it’s not the right design.”
More harm than do well
As more Australians become aware of the need to protect indigenous bee types, many buy cheap hot hotels to set themselves up in their backyard.
University of Southern Queensland Postdoctoral Researcher Kit Prendergast said that these hotels had many defects, which means that they were either not suitable for native bees, or they could cause.
“Some are metal cans with things stuck in it and they can get very hot,” she said.
“Others are only containers filled with twigs, leaves, pine cones and any kind of natural woody material that the bees will not use.”

Dr. Prendergast said that bee hotels had to be carefully designed to attract native bees.
“You want holes that have a diameter of less than 10 millimeters and longer than 10 centimeters, [without] Splinters, “she said.
“You want untreated materials, so those who have not been imported from abroad and are treated with chemicals.”
Need more monitoring
According to the Australian Native Bee Association (ANBA), more had to be done to protect the estimated 1,700 indigenous bee types.
ANBA chairman Megan Halcroft said that there was currently no national monitoring schedule for native bees.

“We don’t know the health status of our indigenous populations of insects,” said Dr. Halcroft.
“We have not done any research and we have no basic data to compare.
“If you don’t know what you started, you can’t know if you have lost numbers or if you have increased the number.”
Dr. Halcroft said that Australia was behind other first world countries when it came to monitoring.
“It has only been in recent years that there has been an increase in consciousness [of natives] Within the broader community, councils and a bit in the government, “she said.
Better back gardens help indigenous bees
Mr. Newman said that the interest of the community in indigenous bees had grown since he first became involved in 2006.
He now passes his knowledge to others and often places his bee hotel specifications online.
Mr. Newman says that bee hotels are useless without native flowers. ((ABC Southern Qld: Peter Sanders))
“I started doing all the wrong things and hopefully ended well,” he said.
“We also have to publish a list of flowers that attract native bees … [you] The hotel can’t just have without the flowers.“
Dr. Halcroft said that people interested in protecting indigenous species must stay away from ordinary European honey bees.

“Honey bees are not at all native to Australia, they are very competitive,” she said.
“There is a lot of competition and we no longer need invasive species.”
Only 11 types of native Australian bees make honey.
Indigenous bees play a crucial role in the environment by pollinating indigenous plants, many of which cannot be pollinated by introduced bees.
