Answers:
Go to a pet supply and buy a timed release sprayer. Buy a few cans of "pyretherins." Ask a sales associate they will know what you are talking about. Pyretherins are made from a flower. They are natural and are non-toxic to humans and animals. The smell might not be pleasant, but they also have scented cans. Ace hardware also carries a package deal with the timed release sprayer with 2 cans of pyretherins. If you cant find anything, go to a hydroponics store and ask about organic pesticides.
