What causes white residue from silver maple tree and how do you stop it?
We have a silver maple tree in our yard, gorgeous and huge. The only complaint we have is that we get a white substance falling from it onto the vehicles and anything else left within the vicinity. This substance is sticky and a pain to deal with. My husband red truck looks like it's snow covered. What is the cause of this and is there anything we can do about it other than getting rid of the tree?

The sticky substance is likely Honeydew. Honeydew is the residue from pests; your tree is likely infested with Aphids.
