An Orange Tree

A friend of ours, who spends a lot of time on cruises, gave us her orange tree. It blooms and really smells very nice. We get some small oranges too. Today when I was doing my spring cleaning in the dining room I had to move the tree. I discovered it had bugs on it and was leaking sap all over the floor. Fortunately it is a hard wood floor and easy to clean, but I was surprised at the size of the sticky mess. I put the whole pot in the kitchen sink and washed the plant with a warm spray then I sprayed the tree with an insecticidal soap. Does anyone know if this is the right thing to do?
