As a single female with Utube and basic skills, I do what I can. However, there are things I would never attempt either for safety reasons or because I would far rather pay someone. Right now it is the squirrels who have taken up residence in the crawl space attic. I was briefly tempted to shove my cat up there, but thought the better of it. Exterminator comes to trap and relocate today. His quote was $150 per squirrel. Hoping for very few squirrels.
