Tree/car/everything covered in tiny bugs
I've never posted on here so apologies if I'm doing it wrong!
I have had a quick look around but not found anything that helps me.
So in May last year, I moved into a new house, has a small front garden with a big tree, little bit of grass and lots of bushes/shrubs. Which has all been fine until now, when going out to my car the other day (which was parked under the tree) I noticed apart from the millions of petals that fall from it, my car was absolutely covered in these tiny little bugs, at first I thought they were tiny spiders but they aren't.
I didn't think too much of it until my wife's car was even worse and then the bins were covered in them too, so I started looking around and they are all over the window sills, the cars, the bins, and the branches and leaves of the tree and shrubs are not visible through them all.
Could someone tell me what they are? If it's normal and what I can do to get rid/prevent them?
Thanks so much for any help!
