Tiny black bug invasion

I live in Sussex County De, near Redden state Forrest. Many people I speak to are having the same issue across the county as I am with tiny black bugs swarming. On several warm days this pst week or two they cover my railing, siding and steps. They look like poppy seeds until you zoom in. Are they harmful? Should we treat and how? This is my new home on the edge of the woods never saw these in summer. Thank you for the help.

What is this bug?

I have found 3 of these in various places around my apartment. At first I thought it was bed bugs but it looks more like a beetle. If anyone knows that would be great!

transplanting Peonies

I have already dug up my peonies for transplanting. Is it too late to move them to their new home or do I need to wait for spring? If I need to wait for spring, what do I need to do to make sure the rhizomes survive the winter?

Honey Crisp Apple Tree

We had an old apple tree removed from our yard, which stopped bearing fruit about 3 years ago. We would like to replace it with a Honey Crisp tree. I read that a pollinator tree needs to be planted nearby.
Which apple trees would be a good choice for a pollinator? Of course, I would like that tree to have wonderful apples as well. The varieties I sometimes choose at the market are Granny Smith, Gala, Fuji, Braeburn. I read that Crimson Crisp are also good, but can't find them locally. How long before apples produce fruit? Would getting larger trees speed things up? Any advice would be welcome
