Plugging big hole in side of house?
Team, where my cable comes in from street, big hole, letting in bugs and moisture. I can still my arm in this hole. Was thinking foam, but it would take a lot to fill out this cavity.

It looks like an electrical box in your wall. You can chip away at the mortar to expose a bit more and you might be able to cover the hole with a blank cover plate. You might need to cut, sand or file some mouse holes in the cover plate for the wires. Then you can caulk any tiny gaps. Or you can use spray foam or mortar to seal up the hole. Or option #3 could be to caulk or foam between the cable box's back plate and your foundation.

I would probably mortar in something like this. But longer. Pack mortar around it to fill up the giant hole.
Run your wires through it... Then put your plastic box over it and the nut will hold the box on. You can then caulk the pipe to seal the wires up. Fairly weatherproof too.

Foam can be used in multiple layers. With a hole like that you could shoot around the wires inside the hole. The wires would hold the foam in place. The foam would expand forming a backing for a second shot of foam.

I believe the first photo is a closeup of what it looks like behind the cable box, when the cable box has been removed. The 3 wires are exactly the same.

I would spray foam as well.
When you spray foam, move spray foam nozzle around edges first. This will ensure the foam sticks to the surface and clear out any dirt left on the surface.
Spray foam basically is urethane adhesive and once it is sealed, it becomes water proof as well.
Do not spray too much at once as the foam will collapse on its own weight and make a big mess. Remember, these spray foam expends 3+ times.

I also believe those are cable wires and the ground coming thru the hole and not service entrance wires. Why would the OP then show the cable box mounted to the wall if they were service entrance wires.
I also first thought they were service entrance wires but then realized what I was looking at when viewing the second picture.

Hi, is there access on the other side? What happened to the cover for the original box, have you contacted the cable co. to see if they would supply you with a new setup?
