Q.Tree Sap on House

Anonymous added on February 23, 2011 | Answered

I have two trees in front of my house, which faces east. The one tree is a┬ávariegated dogwood that is about 10 feet away from the house and approximately 20 feet tall. The other is unknown to me, is about 30 to 40 feet tall, and 25 to 30 feet from the house. It is constantly losing small twigs (very light in weight) and may be diseased as it is split at a ‘V’ in the tree. Which of these trees may leave pin-sized dots of sap on the house and cars? We live in northeast Ohio.

Probably the one that is looking diseased. It is likely not sap but rather honeydew from insects attacking the plant. This is commonly mistaken for sap and pests will attack a diseased tree.
