You're right that Tree of Heaven (Ailanthus altissima) is both invasive and hard to get rid of; it will take some persistence on your part - particularly because your property is surrounded by it.
Tree of Heaven is on the CO Department of Agriculture's Noxious Weed List and they have good information and photos on their website plus a fact sheet that details cultural, mechanical, biological, and chemical strategies for removal. That's the best place for you to start. Here's the link:
