We had a squirrel in our attic at our previous house many years ago. I went to home depot and bought a small trapping cage, baited it with peanut butter, set the trap and caught the squirrell within 2 hours. Then, I draped a towel over the trap, drove him out to the country, and let him go. Pretty simple. Don't waste your money on paying someone else to do it for you.
Use the organic Havahart Small Live Animal Cage Trap to frighten small animals away from your yard. Good for many months of continuous usage.
