Question about tree damage

Question about tree damage

I have a large (probably 40-45 years old) maple tree in my front yard. It's the first maple I've ever had, so I don't know much about it. It loses a lot of small branches (twig size) any time it's windy. But, even more concerning is that I found three colonies of bugs near the base of the tree: 1. Ants--with wings. Two different sizes (large--almost 1/2 inch long and small) burrowing in the groud next to the tree. 2. A light brown bug that looked like a cross between a beetle and a cockroach burrowing INTO the base of the tree and obviously eating at it and disposing of its waste just outside the entrance. 3. Legged worms (centipedes?) that are brown living in the dark brown matter that looks like what the #2 bugs dug out of the tree's base. I panicked and doused them all with Sevin and I've seen no activity for a week, but I'm worried about what this could be and how much damage they've done. The tree is on the north side of the house and I don't want it to be IN my house. Any advice? Or do I need to employ and arborist? Or wait and see? I'm in zone 6/Nashville.
