Calling All Techies

[laguera25]

OK, my techie friends, I need help. In order to install my high-speed Internet, PC had to drill a hole in the outside wall of the house and feed the cable through it. Great. The Internet is aces, but this afternoon, we discovered that ants are using the hole as a handy access point to the house. Is it all right to caulk the hole, or will it damage the cable?
