We have two large trees in front of my house that have what appears to be an aphid infestation - like raining sticky goo 24/7 onto everything around them! I’m having trouble finding someone that can help treat this issue or something we can apply on our own to get ride of this issue. It has been an issue for the last few years. Any help or advice?

That sticky goo is called honeydew, but it isn't so sweet when it drips on everything underneath the tree. The best thing to do right now is to use a powerful spray of water to knock the aphids to the ground. They are not likely to find their way back. Next spring while the tree is still dormant, spray with a dormant oil spray which you can find at your local nursery.
