How do I get rid of ivy on my house?

Pull it down and cut it.

You'll need to do this on an overcast day. First, cover all shrubs and grass with waterproof tarps. Wear clothing that protects you from overspray, as well as eye protection. You'll need to use a Brush Killer spray that precludes anything growing there for at least 6 months. Do not permit the overspray to land on anything you want to grow.

Alternatively, it can be ripped down by gloved hand, but it is tedious and tiring, as roots can be 8' long, plus the height to which it's grown. Cut the stems using a good cutting tool dipped in bleach. This will make the lengths more manageable.

Dispose of all leaves, cuttings. Dig up the surrounding ground to loosen roots.

You are looking at a multi year project, if growth is very heavy.

After application has dried, remove tarps so as not to burn/kill grass and shrubs.

Chop it off at ground level, so it starts to die. Then pull it off the house, carefully, so you don't pull mortar out of bricks, or damage siding.

Kill the ivy's roots with a chemical killer, which you can spray or paint on the plant stumps.
