How to prevent mice from entering house through weather head?

Mice seem to be entering my house through the basement where the electrical service comes in. I checked the outside of the house and everything seems sealed really well, except where the electrical wires enter the house, I think it's called a weatherhead? That has 5 holes and only 2 or 3 of them have wires going in. None of them are sealed and they seem plenty big for a mouse to enter the house through. What can I do to seal these up?

Answer:

The STUF-FIT copper mesh is used to close openings that rodents can get into.  It is usually used with expanding foam. Typically, if you close an opening around a pipe or wire with just expanding foam, the rodents will eat through it. If you place STUF-FIT copper mesh in the hole first and then use expanding foam, the foam will encase the STUF-FIT. Then if rodents try to chew through the foam, they will ingest the tiny shards of STUF-FIT and it will kill the rodents.
You can easily cut the STUF-FIT with a pair of scissors to fit any sized opening
