I went on a date and this happened....?

We were sitting on the sofa relaxing and he was giving me a foot mage. I accidently fell asleep and when I woke up i found him knawing on my toenails. I was so shocked I ran him off. But I think he ha made casual attempts to visit my house several times. For instance I opened the door one day and found some toenail clippers and nail polish on the doorstep. Another day I found some calamine lotion, cotton swabs, and a small child shoe. I am a little nervous. What should I do at this point....
