The Irish beekeeper, who lives in County Galway and has spent his entire life in the area, said he has never heard of a honeybee die, but he would love to see it stopped.
He said the problem of honeybee infestations has been growing over the past 10 years.
“I don’t see it stopping at honey, or at any other kind of products,” he said.
“It is a major concern.
It has been a concern for me since I was a little boy, and I think we have a lot to do about it.”
Mr O’Sullivan, who has spent much of his life in County Dublin, said that for him the biggest issue was the amount of pesticides used to control the problem.
“People need to stop using those products and use more natural ones.
It is a big problem.”
Mr Kavanagh said that even though the use of pesticides has declined, it has not stopped the problem from occurring.
“The bees are still there, they have just gone to other places where they can do it,” he added.
“They are still being eaten up by the honey bees, and the problems will persist.”
A number of the products that are used to kill bees are also toxic to honeybees, he said, adding that it is “absolutely vital” that people stop using them.
“We are not really talking about a product, but a poison, and it is important that people understand that it’s not a product that we take from a supermarket, but that it has come from somewhere, and that it could be poisonous,” he told The Irish Mirror.
