I still can't agree that you call bees and bumblebees "pests". Without these kind of insects we simply wouldn't be able to grow fruit-bearing trees!
Read - for example - here or here.
In parts of China humans have to pollinate flowers manually because of a lack of bees (as a consequence of all our poisonous insecticides)!
If you make a post about it, I wonder if you really can describe my words in the exact same way I mean them. I think you should first seek various articles about bees, bumblebees, flies and beetles as pollinators of our flowers to get some broader knowledge concerning that topic.
yes, your opinion is correct, yesterday I have read many articles, even I also read the book about flower growth. and I found out the truth.
this is my view, about bees, beetles and the like about flowers. hope you read it
